Quick answer: This is the overview for the 8 export documentation guides — for U.S. exporters putting their export paperwork in order for the first time, and for experienced shippers who keep feeling the documents are “almost right.” Documentation problems are rarely about a missing file. More often, the details don’t line up: a supplier’s code copied as-is, an invoice and a packing list that describe different shipments, a quote whose trade term is missing the place and the edition. Read in order: start with the first guide to sort out what has to change for this shipment, then the two core documents on codes and the invoice, then payment, trade terms, and the trade-show guide as needed. Every section below links to its detailed worksheet. Take it slowly — check one worksheet at a time.

Terms and payment

All 8 guides are collected in the Export Documentation Hub — you can also find them one by one from there.
First, Get Clear: What Has to Change for This Shipment
Before quoting for a new market, don’t rush the quote. Sort the proposed changes into three groups: buyer-preference changes, regulatory questions that are still open, and production-capacity changes. Then record the evidence, when each cost will occur, and who is responsible for validating each assumption. If a cost is unknown, keep it visibly unknown — don’t treat it as zero. Adaptation cost is only part of the quote; sales terms, payment, and taxes belong alongside it, but recorded separately. This worksheet helps you think it through. It is not a compliance judgment for any country, and it is not a profit forecast. See Mapping Product Adaptation Costs Before Entering Another Export Market.
Commodity Codes: Don’t Copy a Supplier’s Number
Before using a supplier’s commodity code, ask two questions: which country is it for, and is it for export or import? The Harmonized System (HS) shares only the first six digits across countries; after that, each country extends the code on its own, so a long code can’t be reused without checking. For U.S. exports, check Schedule B; for U.S. imports, check the HTS; for UK imports and exports, use the Trade Tariff tool and HMRC guidance. Settle the jurisdiction and the direction first, then pick the matching official lookup path. This checklist prepares you for that lookup; it doesn’t classify your goods for you. See Before Reusing a Supplier’s Commodity Code: An HS and National-Code Resource Checklist.
Invoice and Packing List: The Same Shipment?
A commercial invoice explains the sale; an export packing list describes the cargo. They have different jobs, but they describe the same shipment. The useful check isn’t whether every box on both documents looks identical. It’s whether the entries that describe the same thing agree: goods description, quantity, invoice number, number of pieces, net and gross weight — the units and the scope have to match. For example, if the invoice says 120 pieces and the packing list says 6 cartons, the numbers may look wrong; but if the packing detail says 20 pieces per carton, 6 times 20 is exactly 120, and they agree. On the other hand, don’t change a gross weight into a net weight just to make the numbers look tidy — first work out what each number actually measures. Take unresolved destination requirements to the customer, the importer, or the forwarder instead of guessing. See Commercial Invoice vs. Export Packing List: A Consistency Worksheet. This is also the most-cited of the 8 guides — invoice and packing-list consistency really is where many documentation problems meet.
Pro Forma Invoice: Ask What the Buyer Needs It For
A pro forma invoice is essentially a quote written in invoice format. A buyer may want it to apply for an import license, arrange a pre-shipment inspection, open a letter of credit, or arrange a hard-currency payment — and the purpose changes what goes in it and what to watch for. So before writing one, ask: who is this pro forma invoice for, and what will it be used to do? Don’t assume every request means the same shipping requirement. See Pro Forma Invoice: Clarifying the Buyer’s Needs Before an Export Sale.
Certificate of Origin: An Invoice Doesn’t Replace It
An invoice can state origin information, but that doesn’t replace a separate certificate of origin. The reverse is also true: a certificate of origin on its own doesn’t automatically prove the goods qualify for a preferential duty rate. The right approach is to ask first: which document does the other side actually need, and what is it meant to prove — then decide whether this shipment needs one document or both. See Commercial Invoice vs. Certificate of Origin: Why an Export May Need Both.
Incoterms in Your Quote: Rule, Place, and Edition
Incoterms divide up tasks, costs, and risk — but copying an abbreviation is nowhere near enough. A quote should state at least three things: which rule is used, the named place or port, and which edition. For example, if a draft says only FCA, with no place and no edition, mark those two as “to be confirmed” first — don’t fill them in on the draft’s behalf. This guide is preparation for reading a quote draft. It doesn’t pick a rule for you, and it isn’t contract wording advice. See Before Reusing an Incoterms Reference in an Export Quote: Check the Rule, Named Place, and Edition.
Payment Terms Change Who Owes What
Cash in advance, third-party escrow, and a letter of credit differ in more than “who pays first.” With direct advance payment, the buyer pays in full (or most of it) before shipment. With escrow, a third party holds the money and releases it only when agreed conditions are met — the money arriving and the money reaching you are two different moments. With a letter of credit, the buyer’s bank commits to pay, and that commitment is tied to shipment and the required documents. Before negotiating, record each arrangement’s payment timing and document responsibilities separately — don’t lump them together. See Cash in Advance vs. a Letter of Credit: A Payment-Timing and Document-Responsibility Worksheet.
Taking Goods to a Trade Show: Plan the Return Trip
When goods go abroad for a trade show and come back, the ATA carnet is the customs document made for that situation: exhibits can enter temporarily duty-free, but consumables and everyday items are not covered. And if the goods might be sold locally, don’t count on the carnet to handle that. Before departure, list the return plan item by item: for each item, whether it comes back, gets sold, or gets used up; who is responsible for the documents at every border crossing; and who to contact if something is missing, damaged, or held. Keep the export-licence question separate — don’t mix it in with the carnet. See Planning Temporary Trade-Show Exports: An ATA Carnet Document and Return-Plan Worksheet.
The eight documents at a glance — each one answers a different question, and most documentation trouble is a mismatch between two of them:
| Document | What it establishes | The mismatch to check |
|---|---|---|
| Product adaptation plan | What has to change for this shipment, what it costs, and who validates it | An unknown cost treated as zero |
| Commodity code (HS / Schedule B / HTS) | The code for the right country and direction | A supplier’s code copied as-is |
| Commercial invoice vs. packing list | The sale and the cargo — the same shipment | Descriptions, quantities or weights that disagree |
| Pro forma invoice | A quote in invoice form, shaped by what the buyer needs it for | Assuming every request means the same shipping requirement |
| Certificate of origin | Origin, as a separate document | Treating origin notes on an invoice as a replacement |
| Incoterms in a quote | Who does what, who pays, and where risk passes — rule, place, edition | A bare abbreviation with no place or edition |
| Payment terms | When money moves and who owes which documents | Lumping timing and document duties together |
| ATA carnet (trade shows) | Temporary duty-free entry for exhibits, with a return plan | Consumables, everyday items, or goods sold locally |
How to Use This Set
These 8 guides are worksheets and checklists — not official forms, and not conclusions about any particular shipment. They share one way of working: write down what is uncertain, mark it clearly, and take specific questions to the customer, the importer, the forwarder, or the customs broker, then check against official sources (for example, the U.S. International Trade Administration’s ITA guidance and the UK’s HMRC guidance). One extra question asked before the goods move is usually much cheaper than discovering a documentation mismatch after they arrive. The full list of all 8 guides is in the Export Documentation Hub.
