Key Takeaways
- A Certificate of Origin (C/O) is an official trade document that certifies the country where a shipment's goods were produced or manufactured, and it feeds directly into customs clearance and tariff assessment.
- Thailand issues two main categories: a non-preferential (ordinary) certificate that simply confirms origin, and a preferential certificate that supports reduced or removed import duty under a free trade agreement.
- Thailand's Department of Foreign Trade (DFT) issues preferential Certificates of Origin, while the Thai Chamber of Commerce and the Federation of Thai Industries are empowered to issue non-preferential certificates.
- Since October 2025, DFT-approved exporters can self-certify origin for eligible trade agreements, cutting down how often a shipment needs to go through a third-party issuing authority.
- Getting a Certificate of Origin in Thailand means confirming the buyer's and destination country's requirements, checking origin status against the applicable rule of origin, and applying through the correct channel.
- An incorrect or late Certificate of Origin export document can result in denied tariff preferences, customs delays, or penalties, so building origin checks into the standard export workflow pays off.

- Frequently Asked Questions About Certificate of Origin in Thailand
A Certificate of Origin, or C/O, is an official trade document that certifies the country where a shipment's goods were produced or manufactured under the applicable rules of origin. This document serves as a means for customs officials in the importing nation to verify the true origin of merchandise, distinct from its point of departure. This verification is essential prior to the assessment of duties, implementation of trade regulations, or the provision of preferential tariff rates pursuant to free trade accords. An incorrect origin declaration may result in a shipment being held in a bonded warehouse pending the resolution of documentation by the buyer’s broker.
A business exporting from Thailand can lower that risk by working with an established international transportation company in Thailand to align freight bookings with origin paperwork. This guide covers the certificate types Thai exporters use most and the steps for getting a Certificate of Origin export document through the correct government channel.
Why Origin Matters in International Trade
Origin matters because governments treat it as a policy lever. A country can grant a lower tariff to goods from a trade partner under a free trade agreement, restrict imports from a specific origin for security or trade-remedy reasons, or apply anti-dumping duties to products sold below fair market value from a particular country. None of that works without a reliable way to establish where a product actually came from, which is what the certificate provides.
Types of Certificates of Origin
Certificates of Origin fall into two broad categories:
Non-Preferential Certificates of Origin
A non-preferential, or ordinary, Certificate of Origin confirms where an export product was made. It does not grant any tariff reduction on its own. Businesses use it to meet general import licensing requirements, satisfy buyer contract terms, support customs declarations in markets without a relevant trade agreement, or provide evidence in anti-dumping and other trade-remedy proceedings.
Preferential Certificates of Origin Under FTAs
A preferential Certificate of Origin supports a claim for reduced or removed import duty under a free trade agreement or another preferential arrangement, provided the goods meet that agreement's specific rule of origin. Thailand is a member of the ASEAN Free Trade Area and the wider ASEAN Trade in Goods Agreement (ATIGA), several ASEAN+1 agreements with partners including China, Japan, and Korea, the Regional Comprehensive Economic Partnership (RCEP), and a number of bilateral agreements, each has its own origin criteria.
Common ways a product can qualify as originating include being wholly obtained in Thailand (grown, mined, or raised entirely within the country), undergoing a qualifying change in tariff classification during production, meeting a required regional value content threshold, or satisfying a product-specific rule set out in the relevant agreement. Because the criteria and forms vary by agreement and by destination market, exporters need to confirm the applicable rule of origin for each shipment.
Certificate of Origin in Thailand: Key Authorities and Channels
Two government-recognized bodies handle most Certificate of Origin applications in Thailand, and the right one depends on the certificate type and the trade agreement involved. Procedures and digital systems continue to change, so it is worth confirming the current process before applying.
Department of Foreign Trade (DFT)
The Department of Foreign Trade, under Thailand's Ministry of Commerce, issues preferential Certificates of Origin for shipments claiming benefits under a free trade agreement, and it is also involved in issuing non-preferential certificates for goods under closer scrutiny. Applications run through the DFT SMART C/O electronic system. Exporters submit the required product, origin, and shipment information online, and the department verifies the origin calculation before issuing the certificate electronically.
Exporters shipping surveillance-listed goods to the US or EU should also watch for upcoming origin-verification requirements DFT has proposed for these markets, which would apply prior to non-preferential C/O issuance.
Thai Chamber of Commerce
The Thai Chamber of Commerce, together with the Federation of Thai Industries, is empowered to issue non-preferential Certificates of Origin for general trade purposes. The Chamber's C/O online system requires users to upload supporting documents, such as the commercial invoice and packing list, for verification before the certificate is issued. This route suits shipments that need proof of origin but are not claiming preferential tariff treatment under a trade agreement, since that claim runs through the DFT instead.
Self-Certification by Exporters Where Allowed
Origin self-certification lets an approved exporter declare a product's origin directly, without applying to DFT or the Chamber for every shipment. The Thai Department of Foreign Trade’s registration scheme for approved and authorized exporters lets qualifying businesses self-certify origin for eligible trade agreements. Self-certification is not available for every product, agreement, or destination market, and registration carries its own eligibility and compliance requirements. Exporters that self-certify still carry responsibility for the accuracy of the origin declaration.
How to Get a Certificate of Origin in Thailand: Step-by-Step
Getting a Certificate of Origin in Thailand typically involves these steps:
Step 1: Confirm the Buyer's and Import Country's Requirements
Review the sales contract or purchase order and the letter of credit, if one is in place, since banks reject documents that do not match its terms exactly. Confirm the import country's requirements for the product, identify whether a non-preferential or preferential certificate applies, and confirm the accepted issuing authority or self-certification method. Coordinate this early with the internal customs and logistics team.
Step 2: Determine Origin Status and the Applicable FTA
Work out whether the shipment qualifies for preferential treatment under a relevant free trade agreement, and which rule of origin applies. This means reviewing the materials used in production, including where imported components, the manufacturing and processing steps carried out in Thailand, and the product's HS classification. Bills of materials and supplier declarations usually supply the detail needed to run the origin calculation accurately.
Step 3: Prepare the Required Documents
Document requirements vary by certificate type and destination market, but most applications need a commercial invoice, packing list, product details and HS code, bill of materials, manufacturing or production records, cost information supporting the origin calculation, and supplier declarations and other supporting origin documents. Exporters shipping surveillance-listed products to the US or EU should check whether DFT's proposed origin-verification requirement applies to them before submitting their application, as this may add a prior verification step to the process.
Step 4: Apply Through the Correct Channel
Register with the applicable system, DFT SMART C/O for preferential certificates and certain non-preferential ones, or the Thai Chamber of Commerce's CO Online for standard non-preferential certificates, then complete the electronic application and upload the supporting documents. Respond quickly to any request for additional information or clarification.
Step 5: Check and Use the Certificate of Origin
Once issued, check the certificate, including exporter and consignee details, product descriptions, HS codes, the stated country of origin, and origin criteria, and consistency with the invoice and other shipping documents. Send the finished certificate to the buyer, the bank if a letter of credit is involved, and the customs broker or logistics provider handling clearance.
Common Certificate of Origin Mistakes to Avoid
Certificate of Origin problems tend to come from the same handful of errors rather than the process itself, and most are avoidable by thorough checking before submission.
Mismatched documents: Product descriptions, quantities, or values that do not match across the invoice, packing list, and Certificate of Origin are one of the most common reasons an application gets rejected or delayed.
Wrong HS classification: An incorrect HS code can point to the wrong rule of origin entirely, so a shipment that should qualify under an FTA gets treated as non-originating instead.
Confusing certificate types: Applying to the Chamber of Commerce for a shipment that actually requires a preferential certificate from DFT, or vice versa, wastes the application window and forces a resubmission through the correct channel.
Incomplete supporting evidence: Missing bills of materials, supplier declarations, or cost calculations for an origin claim is a frequent cause of requests for additional information, which delays the issue date.
Applying too close to the shipping deadline: Processing time varies, so treating the certificate as a last-minute document leaves no room to correct an error before the vessel or flight departs.
Assuming last year's process still applies: Origin rules, forms, and digital systems change, and reusing a template from a previous shipment without checking the current requirement is how outdated origin claims slip through.
How an International Transportation Company in Thailand Can Help
Coordinating C/Os With Shipping Schedules
Aligning origin documentation with container loading and consolidation schedules, customs clearance timelines, and port cut-off or flight schedules prevents origin paperwork from being the reason a booking is missed. A logistics partner that manages both the freight and the documentation timeline can help with this.
Documentation Support and Customs Advisory
Reviewing shipment documentation for gaps before submission, coordinating customs requirements across multiple government touchpoints, and checking for consistency among the invoice, packing list, and Certificate of Origin all reduce the risk of a rejected or delayed application. This kind of support matters most for exporters entering a new market for the first time.
Linking Certificates of Origin With Multi-Country Supply Chains
Origin gets more complicated when raw materials arrive from several countries before substantial processing happens in Thailand, and the finished product ships across ASEAN or further afield. Coordinating freight, warehousing, customs, and origin documentation as a single, connected process, rather than as separate handoffs between providers, reduces the risk of a customs dispute or a denied tariff preference claim further down the supply chain.
