Export Documents Explained

Export paperwork exists to answer three questions for customs and for the buyer: what is in the shipment, what is it worth, and who is responsible for it.

At a glance

  • Nearly every shipment needs a commercial invoice and a packing list.
  • The transport document — bill of lading or air waybill — is issued by the carrier or forwarder, not by you.
  • Certificates of origin matter most when a trade agreement or destination rule depends on where the goods were made.
  • The buyer's bank and the destination customs authority can each add document requirements, so confirm the list before production, not after.

The documents you will see most often

Commercial invoice
The core document. States seller, buyer, goods description, HS code, quantity, unit and total value, currency, trade term and country of origin. Customs values the shipment from this.
Packing list
Physical detail of the shipment: cartons, weights, dimensions and markings. Used for handling, inspection and verifying what arrived.
Bill of lading / air waybill
The carrier's contract of carriage and receipt for the goods. An original ocean bill of lading can also be a document of title, which is why it is handled carefully in payment terms.
Certificate of origin
States where goods were produced. Often required for preferential duty treatment or by the destination country's rules.
Shipper's letter of instruction
Your written instructions to the freight forwarder, authorizing them to act and telling them exactly how to handle and document the shipment.
Insurance certificate
Evidence of cargo insurance. Required by the buyer under terms such as CIF and CIP.

Documents that appear in specific situations

  • Export license or authorization, where the product, destination, end use or end user requires it.
  • End-use or end-user statement, when the buyer must confirm how the goods will be used.
  • Phytosanitary, health or veterinary certificates for agricultural, plant and animal products.
  • Inspection certificate, when the buyer or destination requires third-party verification before shipment.
  • Dangerous goods declaration, for regulated hazardous materials.
  • Consular or legalized documents, required by a small number of destination markets.

How to keep documentation from going wrong

  1. 1

    Ask the buyer for their required document list in writing

    Their customs broker and their bank know what the destination and the payment method demand. Get that list before you produce the goods.

  2. 2

    Make every document agree with every other document

    Descriptions, quantities, weights, values and party names should match exactly across the invoice, packing list and transport document. Mismatches are the single most common cause of clearance delays and rejected letters of credit.

  3. 3

    Describe the goods the way customs needs, not the way marketing does

    Use a factual description with material, function and HS code. “Premium performance kit” means nothing to a customs officer.

  4. 4

    Send documents ahead of the goods

    The buyer often cannot clear the shipment without originals or copies in hand. Late documents create storage charges that someone has to pay.

  5. 5

    Keep complete records

    Retain the full document set for each shipment. Records support audits, disputes, claims and repeat orders.
