Certificate of origin: how to fill it out for USMCA, UK and Australia shipments
A certificate of origin (CO) certifies where your goods were made or produced — not where you shipped them from. Get it wrong and customs can deny the preferential duty rate, hold the shipment, or reject the declaration outright. This guide covers the fields, who can sign it, and how the requirements differ across USMCA, UK and Australian shipments.
General guidance only, not customs or legal advice — requirements vary by shipment and change over time. Confirm current rules with the relevant customs authority or a licensed customs broker before relying on this for a specific shipment.
The distinction that confuses most independent forwarders
There are two different documents that both get called "certificate of origin," and mixing them up is the single most common mistake:
- Preferential certificate of origin — proves the goods qualify for a reduced or zero duty rate under a specific free trade agreement (USMCA, AANZFTA, etc.). Usually self-certified by the exporter, producer, or importer directly on the commercial invoice or a standalone certification statement — no third party required.
- Non-preferential certificate of origin— simply confirms the country of manufacture, with no duty benefit attached. Typically required when a buyer's bank, a letter of credit, or the importing country demands independent proof of origin. In the UK in particular, this type is issued and stamped by an accredited Chamber of Commerce, not self-certified.
USMCA (US–Mexico–Canada) shipments
USMCA has no official government form — any document is acceptable as long as it contains all nine required data elements (USMCA Annex 5-A), certified by the importer, exporter, or producer:
| # | Required data element |
|---|---|
| 1 | Certifier type: importer, exporter, or producer |
| 2 | Certifier name, title, address, phone and email |
| 3 | Exporter name and address (if different from the certifier) |
| 4 | Producer name and address (or “available upon request”) |
| 5 | Importer name and address (if known) |
| 6 | Description of the goods and its 6-digit HS tariff classification |
| 7 | Origin criterion claimed (A, B, C, D or E) |
| 8 | Blanket period, if the certificate covers multiple identical shipments (max 12 months) |
| 9 | Authorized signature, date, and the USMCA certification statement |
Keep the supporting records (bill of materials, supplier statements, origin calculation) on file for at least five years — CBP and its Canadian and Mexican counterparts can request them well after the shipment clears.
UK shipments
For UK exports where an FTA applies, proof of origin usually takes the form of an exporter's declaration on the invoice or, for some agreements, a EUR1 movement certificate obtained through a Chamber of Commerce or HMRC.
Outside an FTA — the more common case for independent UK forwarders — a non-preferential certificate of origin is issued by an accredited Chamber of Commerce (paper or e-certification), typically costing somewhere in the £40–£75 range per certificate depending on the chamber and turnaround speed. You submit your commercial invoice and origin details; the chamber verifies and stamps it.
Australia shipments
Australia has multiple free trade agreements, and the certificate of origin process is not identical across them. Some FTAs require a Certificate of Origin (COO) issued by an authorised body (such as the Australian Chamber of Commerce and Industry); others allow approved exporters to self-certify origin directly. The exact requirement depends on which FTA applies to the specific shipment and destination — always confirm with DFAT guidance or the importing country's customs authority before shipping.
The mistakes that get a CO rejected
- — HS code on the certificate doesn't match the code on the commercial invoice.
- — Description of goods too vague to verify against the origin criterion claimed.
- — Using a preferential (self-certified) format when the buyer's bank actually needed a non-preferential, chamber-stamped certificate — or vice versa.
- — Missing signature, date, or certifier details on a document that's otherwise complete.
Questions
Do I always need a certificate of origin?
No. It depends on the destination country, the trade agreement (if any), and whether the buyer's bank or a letter of credit requires one. Always check the specific FTA or the importer's customs requirements before assuming a certificate is (or isn't) needed.
Can I fill out a certificate of origin myself?
For preferential certificates under most modern FTAs (like USMCA), yes — the exporter, producer, or importer self-certifies, no chamber of commerce required. For non-preferential certificates (common for UK exports without an FTA in play), you typically need an accredited Chamber of Commerce to issue and stamp it.
What happens if a certificate of origin has an error?
Customs authorities can deny the preferential duty rate, delay the shipment, or in serious cases issue fines for false declarations. In one CBP case, an automotive company was fined $2.5M USD for non-compliant origin claims. Accuracy matters more than speed here.
