Do not treat cross-border freight as a domestic shipment with one extra form. Build the document packet from the lane, direction, transaction, commodity, and importer’s instructions. For many commercial moves, that packet begins with a commercial invoice, a transportation document, and a packing list, but those three documents are not a universal clearance guarantee.

Use this checklist before pickup, then have the importer or customs broker confirm the final set. The U.S. International Trade Administration advises exporters to ask the foreign customer or importer which documents the destination country requires because special documents can depend on the product and shipment. This guide was verified against official U.S. and Canadian government sources on July 21, 2026. It is a preparation tool, not customs, tax, or legal advice.

The short cross-border document checklist

Copy this section into the shipment file and mark each item complete.

Which three documents form the working core?

Commercial invoice

The commercial invoice describes the transaction and gives customs the information used to examine classification, origin, and value. The International Trade Administration identifies it as one of the main documents customs uses when determining duties. It should be based on the seller’s records, not copied from a generic template without checking the destination rules.

For merchandise imported into the United States, 19 CFR 141.86 lists required invoice information. It includes the parties and transaction, detailed merchandise descriptions, quantities, purchase price or a supportable value for non-purchased goods, currency, specified charges, country of origin, and certain assists. It also requires the invoice to identify what is contained in each package. A vague label such as “parts,” “samples,” or “miscellaneous goods” does not supply the detailed merchandise description the rule calls for.

For every product line, check:

A plain-language description that says what the product is, what it is made of, and, when useful, what it does.
Quantity and unit of measure.
Unit price, extended value, and currency, or a documented basis for the declared value when there is no sale.
Country of origin. Do not substitute the export country or warehouse location.
Tariff classification used by the responsible importer or broker.
Package marks or references that connect the line to the packing list.
Itemized charges or other valuation information required for the destination entry.

Bill of lading or transportation document

The transportation document governs the carrier’s movement and identifies the parties, freight, route, and handling instructions. The International Trade Administration explains that a bill of lading is a contract between the owner of the goods and the carrier. Its legal characteristics vary by mode and form: for example, a straight ocean bill of lading is non-negotiable, while an order bill may be negotiable. Do not describe every LTL bill of lading as a document of title.

Check that the transportation document uses the same shipper, consignee, package count, commodity description, weight, and identifying references as the rest of the packet. Add the proper proof-of-filing citation or exemption legend when the U.S. export filing rules require one; do not invent an AES number or copy one from another shipment.

Packing list

The packing list is the package-level map. The International Trade Administration says it should itemize contents, packaging type, package count, net and gross weight, marks, and dimensions when appropriate. It is not a substitute for the commercial invoice.

Build it from the freight actually tendered. If the invoice says 120 units across four pallets, the packing list should let the importer, broker, carrier, and examiner determine which units are on each pallet. Recount and reweigh after final packaging rather than carrying forward preliminary quote measurements.

Which lane are you shipping?

Use the receiving country’s rules first. A document used on one direction of a lane may not be the document used on the reverse direction.

Goods entering the United States

Start with the U.S. importer and its customs broker. They should confirm the entry data, responsible parties, classification, origin, value method, admissibility, bond or entry requirements, and any partner-government-agency documents. For the commercial invoice, use the current U.S. requirements in 19 CFR 141.86 rather than a carrier’s abbreviated field list.

The invoice and packing information must describe the real merchandise. When goods are not sold—such as samples, returns, transfers, or replacements—do not enter a token value without direction. The U.S. invoice rule still calls for a value basis for non-purchased merchandise.

Goods entering Canada

The Canada Border Services Agency’s invoice memorandum describes three possible invoice approaches for most commercial goods entering Canada: a commercial invoice containing all required information; a commercial invoice with core transaction details plus Form CI1 for the remaining information; or a completed Form CI1. The memorandum lists required fields including the vendor, consignee, purchaser, shipment date, country of origin, conditions of sale, currency, quantities, description, and values.

CBSA marks that memorandum as under review following the transition to the CARM system. Treat it as an official field checklist, but have the Canadian importer or broker confirm the current accounting and submission workflow. Do not claim that every Canadian shipment needs a standalone Canada Customs Invoice; the official guidance provides more than one documentation path.

Goods entering Mexico

The U.S. Commercial Service’s current Mexico import documentation guide says commercial crossings require a completed pedimento. It states that the pedimento is accompanied by a commercial invoice in Spanish, a bill of lading, and any applicable undervaluation or product-compliance documents. The guide also stresses the role of the Mexican importer and authorized customs representative.

Before pickup, obtain the Mexican importer or customs broker’s exact instructions for the commercial invoice, Spanish-language information, tariff classification, importer registration, permits, and any Carta Porte data. The U.S. exporter’s packet supplies information for the process; it does not replace the Mexican importer’s customs declaration.

Do you need an EEI filing or an exemption citation?

For exports from the United States, evaluate Electronic Export Information by Schedule B number and filing rule, not just by the shipment’s total invoice value. The U.S. Census Bureau’s Foreign Trade Regulations guide states that commodities valued at $2,500 or less under each individual Schedule B number are generally covered by the low-value exemption, while a license or another mandatory filing condition can override that exemption.

Shipments from the United States to Canada are generally exempt from AES filing, but the Census guidance lists exceptions, including certain licensed goods, rough diamonds, goods stored in Canada before movement to a third country, and goods transiting Canada to another destination. “Going to Canada” is therefore not enough by itself to close the EEI question.

Record the decision in the shipment file:

Who determined the Schedule B number?
Who is the U.S. Principal Party in Interest?
Who will file, if filing is required?
What is the filing deadline for the mode and commodity?
Which proof-of-filing citation or exemption legend belongs on the loading document?

Does a USMCA certification belong in the packet?

Only add a USMCA certification when someone intends to claim preferential tariff treatment and the goods satisfy the applicable origin rule. The Mexico guide notes that a USMCA certification uses nine minimum data elements and may be completed by the importer, exporter, or producer. It does not need a prescribed form, but that flexibility is not permission to guess.

Keep the product description and Harmonized System classification consistent with the invoice, and retain the supporting origin analysis. “Made in North America,” “shipped from Canada,” or “purchased in Mexico” does not by itself establish that a product qualifies under a USMCA rule of origin.

Run a final document-matching check

Compare the documents side by side before release to the carrier.

Field	Commercial invoice	Transportation document	Packing list	Filing or certification
Parties	Seller, buyer, importer and consignee as applicable	Shipper and consignee	Shipment references	USPPI, filer, certifier or importer as applicable
Goods	Detailed line-item descriptions	Accurate transportation description	Package-level contents	Classification and origin tied to the same goods
Quantity	Units by product line	Pieces or handling units	Units within each package	Quantity or value reported under the applicable rule
Weight	Product or shipment weights as required	Tendered freight weight	Net and gross package weights	Weight only where the filing calls for it
Value	Price or supportable declared value and currency	Do not add a customs value unless required	Usually not the valuation record	Value reported under the applicable filing rule
References	Invoice and purchase-order numbers	BOL, booking, or carrier references	Invoice and package marks	ITN, exemption legend, permit, or certification reference when applicable

Resolve differences rather than adding a note that the documents “may vary.” A legitimate distinction—such as net product weight on the invoice and gross pallet weight on the packing list—should be labeled clearly. An unexplained difference in quantity, origin, value, or consignee should be corrected by the party responsible for the record.

Prepare the quote and customs handoff separately

For a freight quote, gather the origin and destination postal codes, packaged dimensions and weight, commodity description, handling-unit count, freight class when applicable, and pickup or delivery services. Use the checklist above to identify the customs parties and documentation work, but do not wait for a quote screen to determine customs compliance.
