The October 23 US decision splits Canadian-product coverage into additions and removals. Match your confirmed product code and customs records to the worksheet to compare existing stock with the next purchase.
Canada tariff changes: two refrigeration codes, opposite cost directions
The essentials in 30 seconds
- Compare your products before drawing a national conclusion.
- Similar product names can sit on opposite sides of the change.
- Separate ordering, shipping and arrival from the customs event specified in the proclamation.
- Review remaining duties, costs and contractual allocation after one tariff layer changes.
- The worksheet is for manual document review, not automatic classification or a tax calculation.
01
Some products leave the tariff while others enter it
On October 23, 2026, the US decided to remove Part A products from its 50% Section 338 tariff coverage for Canada and add Part B products.[C1] The customs conditions below apply.[C3] Even products bought from the same supplier can therefore face pressure in opposite directions in the next quotation.
The first business question is which row of the change applies to a particular product, rather than simply whether the company buys from Canada. Equipment staff may group several purchases under refrigeration, while the annex separates them into different codes. Treating an internal product name as a customs classification can leave a procurement team expecting relief when it should be examining the addition instead.
This is a separate legal action from Canadian factory assistance, domestic vehicle-emissions standards or private sales contracts. The administration cites disadvantage from Canada’s automotive measures.[C1] That political explanation cannot determine the economics of an individual machinery or packaging purchase. Product coverage is the starting point; buyers’ and sellers’ trading terms determine the subsequent effects.
Take one product to both annexes
Work with a confirmed HTS classification, product specifications, the relevant customs records and quotations in your own files. The worksheet identifies what each document establishes and which answer is missing. It does not classify a product entered into this site, and no confidential contracts or customs documents need to be submitted. If the code itself is uncertain, preserve that question for the person responsible for classification.
A procurement file may contain removals, additions and products absent from this particular change. Applying one rate change to the whole company merges purchases requiring different questions: where to examine a lower offer and where to ask for evidence behind an increase. Sorting the direction by product first helps sales, procurement, customs and finance establish whether their different documents concern the same transaction.
That mixture also provides a better starting point for the international implications. Even unchanged total trade can contain changes in product composition and the distribution of margin between counterparties. Flat exporter revenue would not prove that nothing changed, and a larger product list would not imply a proportionate fall in national exports. Connecting the changed rows to quantities and contracts narrows the route to earnings and supply chains.

02
Do not merge 8418.69.01 and 8418.30.00 under one equipment name
Part A includes 8418.69.01, other refrigerating/freezing equipment, not elsewhere specified; B includes 8418.30.00, chest freezers of no more than 800 litres.[C2] These are two actual codes with opposite changes. A product’s everyday name, appearance or a single word about its use does not establish which classification applies to it.
A factory upgrade can purchase an equipment package containing more than one classification. One line in a capital budget may therefore differ from one line in a customs record. Connect quotation identifiers, specifications and quantities to the codes established by the responsible specialist, and identify whether the assessment concerns the package or individual items. This is not an invitation to assign unsupported codes merely to make the spreadsheet look detailed.
Descriptions inform; they do not delimit coverage.[C2] Making a product name resemble a short translation is not a way to establish treatment. The worksheet is more useful when it records the specification and classification basis used, rather than a perceived match to a description. Switching to a similarly named item also raises two questions: whether it meets the operational specification and whether its customs treatment is the same.
A description is not the boundary of coverage
Annex II changes subheadings in HTSUS chapter 99 note 51(b)(3).[C3] A bare A in an internal ledger loses the version of the table used. Recording the annex date, code and direction of change together makes it possible to trace whether a later difference comes from classification or a change to the measure itself.
B excepts civil aircraft/parts meeting HTSUS General Note 6.[C2] Finding a code in B and establishing that a transaction meets an exception are separate steps. An equipment team describing an item as aviation-related is not enough to establish the exception. A claimed exception needs its supporting documents and the responsible person’s confirmation in a separate field.
A product absent from the annex should not be marked duty-free. Absence establishes only the reach of this replacement list. Its existing treatment, other duties and relevant exceptions still need to be checked against the product’s records. The worksheet’s third category preserves a question that this particular change does not answer; it does not declare the product outside all tariffs.

These are code examples, not classifications inferred from product names.
| Object | Annex I location | Annex II connection | Your record to connect |
|---|---|---|---|
| 8418.69.01 | A: removal | Deletion from note 51(b)(3) | Confirmed code, specification and transaction |
| 8418.30.00 | B: addition; exception below | Insertion in the same note | Confirmed code, exception evidence and transaction |
| Item absent from this change | This replacement alone does not settle treatment | Check existing treatment separately | Prior treatment, other duties and classification basis |
A shared equipment label does not establish a shared direction of change.
03
Do not replace the October 30 customs boundary with an order or arrival date
The specified boundary is a consumption entry or withdrawal from warehouse for consumption on or after 12:01 a.m. eastern time on October 30, 2026.[C3] These are customs events, respectively an entry for consumption and a warehouse withdrawal for consumption. This is why a logistics arrival schedule and the customs owner’s explanation of effective timing can be different records. Approaching the border alone does not establish which side of the change applies.
For a Part A product, stock already entered for consumption and cargo awaiting the relevant event require different questions. The prospective effective clause does not by itself establish a refund of a past charge. For the latter cargo, the record of the customs event matters more than a planned delivery date. This is a comparison of two inventory states, not a recommendation to accelerate or delay a company’s shipment.
For a Part B product, placing an order before the change does not by itself remove the new condition. If the cost assumed at contracting differs from the cost associated with the customs event, the contract must answer who bears the difference. A fixed price, a separate tariff line or a renegotiation clause can transmit the same timing change differently to the buyer and seller.
Check the recorded event even for goods on the same shipment
When comparing timestamps, retain the local time and timezone together. A company managing North American purchases from another region may see the same displayed date in systems using different clocks. Ask which event was recorded and which timezone the record uses when connecting it to the proclamation’s boundary. An order-system timestamp cannot stand in as evidence for the time of the customs event.
Warehouse also needs care. Receiving goods into an ordinary warehouse is not the event called withdrawal from warehouse for consumption in the proclamation. When a warehouse owner says goods have been received, establish whether the answer concerns storage or a customs withdrawal for consumption. Rather than assigning treatment by matching a storage location to a word in the article, align what the customs and logistics records actually record.
Timing can reach near-term cash planning and quotations before any longer-term decision to move production. Bringing forward a date in a plan, however, is different from validly completing the required procedure then. Keep cargo whose timing is unresolved separate from cargo with confirmed records. That prevents a prospective saving or additional charge from entering a budget as though it were a settled amount.
For a separate case in which cargo release and later tariff certainty diverge, Read about origin evidence and tariff certainty after release.

04
Put the removed 50% layer beside the costs that remain
Part A removes the relevant Section 338 additional duty. The fact sheet says coverage applies regardless of USMCA origin qualification and that the duty is additional to applicable Section 232 duties.[C4] Calling A duty-free, or adding Section 232 to every product indiscriminately, would both distort the cost sheet. Establish the applicability of each layer for the individual item.
For a fictional illustration, hold the valuation at 100 in the same currency and compare only this additional duty. A charge of 50 makes the amount including that layer 150. Removing it for A gives 100, a reduction of about 33.3% from 150. Adding 50 to B from zero moves 100 to 150, a 50% increase. The same change of 50 does not produce symmetric percentage changes when the starting amounts differ.
The example excludes other duties, freight, insurance, fees, storage, finance and negotiated discounts. It does not represent an actual valuation or combination of taxes. Its purpose is to align the denominator when comparing a 50% tariff rate with a percentage change in acquisition or selling cost. A total-cost comparison needs the same cost perimeter before and after, with unknown items left unresolved rather than entered as zero.
Keep a controlled calculation separate from total cost
When a supplier presents a tariff-related increase, ask separately about the product, transaction, valuation used and contractual allocation. A rate document does not establish the composition of the selling price. Conversely, demanding an equal price reduction merely because an item is in A can miss differences in inventory or sales contracts. Agreement on the terms held constant provides a starting point for the negotiation.
Finance can inadvertently combine two different additions: costs layered on one transaction and changes aggregated across products. Calculating the second before establishing the first can hide large unresolved assumptions inside a small net figure. Confirming product direction and duty layers before aggregating the supported amounts gives management a more interpretable number.
Equal counts of additions and removals would not mean balanced costs. Each row can cover different quantities, prices and purchase frequencies. Code counts describe a list, not trade value, company numbers or employment. Estimating global growth or inflation effects would require further evidence such as covered trade values and substitution. The length of this annex alone cannot establish the economic effect.
Figure 3 · Compare only the additional-duty layer at a fictional valuation of 100

Part A: the relevant additional duty moves from 50 to 0
Part B: 0 to 50 where coverage applies and no exception does
Totals including only this layer move 150→100 for A and 100→150 for B. Different starting points give about −33.3% and +50%.
05
A and B reverse the comparison between existing stock and replenishment
Consider a distributor holding a Part A product. If stock already through the relevant customs event has a different acquisition cost from the same product replenished after the change, two cost bases will coexist at sale. A lower expected replacement cost does not automatically improve the margin on current stock. Competitors able to quote on the new cost basis could instead put pressure on a distributor holding inventory bought at the older cost.
A Part B item can present the opposite relationship. Stock associated with the earlier treatment may offer near-term pricing room if replenishment becomes more expensive. Selling it, however, creates a need to replace it on the higher basis. Discounting solely against historical cost may leave too little cash for that purchase. The advantage depends on when inventory is used and the price accepted for the next order.
If both refrigeration codes occur in one upgrade, the net equipment budget can hide this difference. Lower A replenishment costs and higher B costs might offset, while earlier and later deliveries still produce different cash flows. Add columns for stock on hand, cargo awaiting the relevant event and the next replenishment to the product table. A stable total budget can then reveal which rows still need an examination of purchasing sequence.
Inventory value and the next purchase price
Equal inventory quantities can also represent different commercial states: ready-to-sell goods, equipment awaiting an installation slot or customer-specific products. Their flexibility in responding to price changes differs. After confirming customs status, ask sales or equipment owners how much can actually be sold or used elsewhere. Treating every unit on the books as freely saleable can overstate the ability to absorb the cost change quickly.
Keep finance’s acquisition-cost record beside procurement’s replacement quote, with their different purposes explicit. One explains goods held; the other informs terms for future commitments. Accounting recognition depends on the company’s policies and actual transactions, so the illustration is not a basis for changing the books. Mark whether each number is an incurred cost or a counterparty’s quotation.
The evidence that would change this reading is concrete. If a new A purchase costs no less, examine supply price, other duties, freight and contract terms. If B quotations are unchanged, ask whether the seller absorbed the difference or the transaction falls outside the comparison. When observed numbers move against the expected direction, check whether the quotations concern the same product, quantity and timing before concluding that the measure had no effect.
06
Read who bears the change by matching the quotation to the contract
A pricing contract stands between product coverage and the buyer’s invoice. A seller committed to a fixed delivery price may not be able to invoice the customer for the entire additional burden. A separate-duty arrangement raises the question of which charge is settled against which document. Ask how a clause applies to the particular item, order and delivery, rather than relying on its heading or inferring the answer from general trading practice.
A removal calls for the same contractual review. Negotiating evidence differs depending on whether the seller holds stock acquired at the older cost or will deliver replenishment under the new conditions. The buyer can ask where the affected cost sat in the quotation. The proclamation does not itself rewrite a private selling price. Matching the source to the counterparty’s explanation is a practical way to isolate the unanswered cost item.
An additional-duty line on a quotation still needs to match the covered goods. Check whether a uniform rate has been applied to an entire equipment package, whether unaffected items are included, or whether entered stock and unresolved cargo have been combined. This does not presume an error by the counterparty. It creates a common set of documents for locating a difference in specification, classification or contract terms.
Compare the same currency, cost perimeter and quantity
Align currency, conversion date, quantity and cost coverage when comparing Canadian supply prices with US costs. Keep tariff and exchange-rate changes separate within the quotation difference, identifying the portion that is comparable.
A shorter quotation-validity period can impose a burden separate from price. A seller unable to settle changing assumptions may commit only briefly and reprice later deliveries. The buyer’s work then extends from comparing unit prices to coordinating the deadline for internal approval. This is a condition to examine in a mixed A/B equipment project, not evidence that the response has already occurred widely.
The party making a payment, the party handling customs procedures and the party ultimately absorbing the cost need not be the same. Before using a single word such as payer, list the cash-paying entity, the contractual settlement counterparty and the business whose margin changes. This prevents a customs answer from being treated as a conclusion about selling prices, or a finance payment from being confused with a decision about economic incidence.
For the basics of how currency changes the way a business experiences costs, Read how exchange rates reach business costs.

07
Match comparable conditions before switching product or country
A company seeking another source for a B item first needs products that perform the same job. The existence of an A code does not make its equipment a direct substitute for a B product. Capacity, installation, power, maintenance and lead time can change the meaning of a price gap. A customs difference is not evidence of operational equivalence—an important practical implication of the refrigeration comparison.
Changing supply country requires a separate review even where the code is the same. This proclamation changes treatment of Canadian products; it is not a complete cost schedule for buying a similarly named item elsewhere. Add specification equivalence, responsibility for explaining origin and actual delivery time to competing quotes. A different shipping route should not be assumed to change the product’s origin.
For equipment, post-purchase work can outweigh a short-term price gap. Installation, staff familiarization, spare parts and breakdown support can constrain when a new machine is usable. Rather than predicting immediate substitution from the tariff gap, examine compatibility and the implementation schedule for each product. A price change reaching an order can still leave further conditions before it reaches production capacity.
Include the work needed after delivery
Repeated purchases of packaging and equipment installed for years also require different comparison units. The former can transmit changes through the next order and inventory turnover; the latter through the replacement cycle and downtime. Separate consumables from capital purchases before turning one supplier’s cost change into a company-wide sourcing conclusion. Alongside mixed A/B coverage, purchase frequency changes how the measure appears.
An opportunity for a third-country supplier has specific conditions: it must genuinely compete with the covered Canadian product, meet the required specification and volume, and arrive within the buyer’s implementation window. Producing something in an added category alone does not establish higher orders. A supplier without spare capacity may receive inquiries without increasing deliveries. Examine the price gap, product fit and available supply together.
An A removal may give US buyers room to reconsider a Canadian product. Yet a project that has already qualified another supplier and arranged tooling or service can face costs in switching back. Separating new quotations from contract transitions explains why improved costs might not bring orders back immediately. In evaluating sourcing changes, do not count an inquiry, a signed contract and an actual delivery as the same outcome.
08
SG Group View: examine transactions moving in opposite directions
The easy overreading is that removals mean a uniform easing of US–Canada costs. Additions appear in the same annex, and the two refrigeration codes split even within a broad industry label. SG Group starts with transactions in the changed products rather than an average national tariff. That makes it possible to identify who might obtain lower replacement costs and who needs to resolve an additional contractual burden.
This does not make the tariff change immaterial. At a common valuation for a covered product, the direction of the added or removed layer is clear and can justify revisiting quotations and procurement budgets. The unresolved connection is its translation into a company’s overall margin or retail prices. Covered revenue, inventory status, contract settlement and substitutes connect the definite legal change to a range of possible business effects.
Margin shares can move before volumes. A B supplier discounting to preserve sales may leave the buyer’s invoice little changed while reducing its own margin. With weak competition in an A product, the benefit may initially remain with an intermediary rather than reach the final customer. These are conditional channels; assessing the outcome requires comparable quotations, transaction prices and quantities for the same product.
Margin redistribution and changes in volume
Inflation transmission also becomes misleading when additions and removals are forced into one direction. A consumer product may connect directly to its selling price; factory equipment works through its useful period and output. A one-off change in equipment acquisition cost cannot establish the same percentage change in every finished product. Trace the purchased item to the cost of the particular process before inferring international price competition or investment effects.
Evidence against this interpretation would be an absence of behavioral differences after identifying genuinely covered transactions. If comparable A and B quotes and purchase volumes continue to move together, other costs or demand may dominate the difference. Conversely, a divergence explained by seasonal volumes or another contract change cannot be attributed solely to the proclamation. The analysis should not turn every possible result into proof of its effect.
09
Three counterarguments that could change the assessment
The first counterargument is that the changed products account for little of a company’s business. Even a large rate can have a small overall earnings effect when covered quantities are small. Test that claim against actual sales or purchasing composition. A small spending share, however, differs from a missing machine essential to an upgrade. Put value alongside irreplaceable processes and delivery deadlines to assess financial and operational importance separately.
The second is that discounts or seller absorption smooth away the difference. A nearly unchanged final invoice would not necessarily mean the measure was irrelevant; the supplier’s price or margin may have changed. Examine the breakdown of comparable quotes, not only the duty-inclusive total. Evidence that the buyer absorbed no burden is different from evidence that no participant in the transaction absorbed one.
The third is that demand or product specifications matter more. A refrigeration buyer postponing capital spending may place no order despite better A conditions. A B buyer may continue purchasing if no alternative meets the required capability. Testing this explanation needs the buyer’s budget, implementation plan and feasible models alongside the tariff comparison. Do not assume flexible substitution from the duty gap alone.
Return to the transaction when a difference fails to appear
An unimplemented tariff also starts from a different comparison. It asks about a burden that did not occur. Here, specific rows leave existing coverage and other rows enter it, making a before-and-after match possible for a product. Private pricing decisions are still not settled by that change. The next task is to find the evidence connecting the direction of the legal change to the behavior businesses choose.
Retaining counterarguments makes unexpected observations useful. A price that fails to rise prompts questions about demand, inventory use or seller absorption; a price that fails to fall prompts questions about fixed contracts or other costs. Keeping code, timing and cost coverage aligned makes the next quotation a way to update the view, rather than forcing it into a predetermined conclusion.
For a different comparison involving a charge that did not take effect, Compare an unimplemented tariff with its counterfactual.
Figure 5 · Read one procurement file through A, B and absence from the change
Begin with a confirmed code. An unresolved classification returns first to its owner.
A · Removal
- Example: 8418.69.01
- Match specified customs event/time
- Identify removed layer and remaining costs
- Separate old stock and replacement quote
B · Addition
- Example: 8418.30.00
- Check evidence for the annex exception
- Match customs event and remaining layers
- Check fixed pricing or separate settlement
Absent from this change
- Do not enter duty-free
- Return to existing treatment and other duties
- Record what this replacement does establish
- Ask an owner the specific outstanding question
The three branches lead to different documents and questions, not one conclusion.
10
Connect product, customs timing and remaining costs in one record
Start Figure 6 with one potentially material product. Record its internal identifier and specification, the basis for the confirmed classification, and its match to A, B or absence from this change. Do not fill a gap by guessing. Where an everyday product name cannot be connected to a customs code, the first question is which document establishes the classification, not the duty amount. Identifying the owner of that missing evidence is already useful progress.
Next match the Annex I row to the Annex II modification, retaining an answer about the exception where relevant to B. A consultation date helps locate the same version later. If a counterparty supplies a different code or table, record the changed basis instead of overwriting only the conclusion. Keeping a classification correction separate from a change to the coverage list makes a revised financial estimate easier to explain to management.
Separate planned and completed events in the customs field. Identify the record establishing the event and timestamp for consumption entry or warehouse withdrawal for consumption. An arrival estimate alone leaves the customs timing unanswered. The article need not decide whether a shipment should be expedited. First establish what the customs owner can explain, then distinguish estimates depending on a future event from amounts concerning completed transactions.
Turn an unanswered field into a question for its owner
Separate the changing layer, remaining duties and costs, and contractual allocation. A quote needs its currency, quantity, period and cost coverage. Use different columns for an amount associated with an actual customs transaction and an estimate for a future purchase. The aim is to expand the comparable portion, rather than rush to one total. An empty field can then be identified as a missing cost item or an answer still needed from an owner.
Finally identify whether the record concerns stock on hand, unresolved cargo or the next replenishment. Different costs across those states change the numbers used in negotiation and cash planning. Connect sales’ customer price, procurement’s supplier quote and finance’s expected payment to the same row. This can reveal colleagues discussing different transactions despite having read the same tariff headline.
The table does not determine classification, an exception, a duty assessment or legal compliance. It supports manual comparison of documents and specific questions to responsible people. It requires no site input, storage feature or automatic determination; adapt the relevant fields to your own records. Separating established fields from pending answers turns a vague request for more research into a task with a product, document, question and owner.

Build three scenarios from the two refrigeration codes
In the first scenario, coverage is established and new quotations reveal a difference. A replenishment terms may improve while B offers include the additional burden. Compare transactions meeting the confirmed code and customs conditions, rather than a uniform revision across all business with the supplier. Next examine whether quotations become contracts, whether quantities change and which participant absorbs the difference.
In the second, the legal direction is clear but contracts or stock delay the invoice effect. A goods shipped from older-cost inventory and B goods delivered under fixed-price terms may reveal little difference in near-term invoices. Replacement quotes and contractual settlement explanations become more useful. An unchanged price does not establish a zero effect; identify the lag that remains.
In the third, an unanswered code, exception or customs event prevents a like-for-like comparison. A supplier’s equipment name without classification evidence, an unsupported B exception or an arrival estimate without the relevant event narrows the questions required before stating an amount. Marking the missing field supports a targeted inquiry to the owner, without jumping from an information gap to a blanket decision to stop all trading.
Which observation changes the scenario?
The first scenario weakens if comparable specifications and quantities show no quotation difference along the added and removed directions. The second weakens if the expected difference still fails to emerge after stock turns over and contracts change. The third resolves when the responsible owner supplies the record. These are not growth forecasts; they organize which document would advance the company’s comparison.
12
Use the next documents to reconnect the changed rows to actual transactions
CBP is authorized to issue implementation material and technical corrections.[C1] Examine which element a later document clarifies: code, exception, reporting method or timing. This is not a scheduled promise of a new release at a particular hour. Retaining the October 23 reference makes subsequent explanations traceable.
From October 30, the useful evidence is a transaction record corresponding to the specified event, together with comparable quotations. Documents establishing completed events can narrow a prospective cost estimate beyond a purchase plan alone. Confirm aligned assumptions row by row in A and B before rebuilding the company-wide estimate; that also reveals how much remains unanswered.
For a later statistical comparison, align codes, value versus volume and periods. National changes containing products absent from this replacement cannot stand in for effects on the two refrigeration codes.
Move from quotations to realized costs and quantities
Company results should connect revenue, margin, stock and cash. Lower A purchasing costs might leave no extra profit under competition, while stable B volumes might still require more working capital. When management refers to tariff effects, ask which product, cost and period it means. The two-code comparison supplies a concrete question for connecting that explanation back to the business and its transactions.
The proclamation alone does not establish a company’s valuation, contractual burden, delivery volume or pass-through. These require business records, not an interpretation of list length. If an aggregate omits unresolved transactions, retain the omitted quantities and cost categories in the management record. A supported number for a small subset should not be extended into a settled figure for all transactions.
The entry point into a company decision is one product row. Match the confirmed code to A and B, connect Annex II, and place the specified customs event beside remaining costs. Adding inventory, replenishment and the contractual counterparty separates transactions where relief is plausible, those requiring an answer about additional burden, and those awaiting classification or timing evidence. That distinction is more useful for the next quotation than a broad conclusion about Canada.
Frequently asked questions
Does USMCA origin qualification by itself avoid this addition?
The fact sheet says covered Canadian goods are subject regardless of USMCA origin qualification.[C4] Match origin evidence separately from this additional-duty coverage, and establish other relevant conditions, including the B exception, with the responsible owner.
Can cargo ordered before the change be calculated on the old basis?
Use the customs event and clock explained in the text; the order date is not enough. If the quote uses earlier assumptions, ask separately about the customs event and the contractual allocation of any difference.
Does holding a Part A product establish a refund of an earlier duty?
The prospective clause alone does not establish a refund for an earlier transaction. Separate records of completed customs events from future replacement quotations, and ask the responsible specialist about the procedures applicable to the earlier transaction.
Can A and B differences be netted on a mixed invoice?
Align classification, timing and cost coverage by item before aggregating an internal estimate. A small net figure can conceal unresolved exposure. Actual customs reporting and settlement must follow the applicable procedures and contract, not an aggregation inferred from this table.
Does the 800-litre description classify my freezer into B?
Capacity is one field. Match the product and description conditions in the text to specifications and classification evidence, then ask the classification owner. A product name or one number does not establish your item’s classification.
Does absence from this change mean procurement cost stays the same?
This replacement list does not establish existing duty treatment or changes in supply price, freight or currency. Absence from the list is not proof of unchanged total cost. Compare quotes at the same specification, quantity, currency and cost coverage.
Does removing 50% make the selling price fall by 50%?
The selling-price denominator need not equal the valuation used for the additional duty. Figure 3 moves from a fictional 100 plus 50, or 150, back to 100—a reduction of about 33.3%. It excludes other duties, costs and margin, so it is not a forecast of the actual selling-price reduction.
Must I upload documents to use the worksheet?
No. Compare authorized documents in your own records using Figure 6. It is not an input, generation or storage service; it organizes the documents and answers needed. Confidential contracts, customs documents and customer information do not need to be sent to this site.
