Import vs Export Declaration: What's the Difference?
An import declaration is filed with Thai Customs to declare imported goods and pay duties and taxes before goods are released from the port. An export declaration is filed to declare goods before they leave Thailand. The key differences are the direction of goods, supporting documents, tax obligations and how the declaration is used afterwards.
What Is a Customs Declaration?
A customs declaration is the document used to report details of imported or exported goods to the Customs Department, including product type, HS code, quantity, value and country of origin or destination. Declarations are filed through Thai Customs' electronic system, and the data is used to calculate duties, check permits and compile trade statistics.
The declaration can be filed by the importer or exporter directly, or by a licensed customs broker on their behalf.

| Topic | Import Declaration | Export Declaration |

Import Documents: What an Import Declaration Requires
- Commercial Invoice showing value and sale details
- Packing List showing packages, weight and packing
- Bill of Lading (sea) or Air Waybill (air)
- Import permits for controlled goods, such as items regulated by the Thai FDA or TISI
- Certificate of Origin, if claiming preferential duty under a trade agreement
Export Documents: What an Export Declaration Requires
- Commercial Invoice and Packing List
- Vessel or flight booking details
- Export permits for goods under export control
- Tax benefit documents, such as duty refund or investment promotion privileges (if applicable)
After export, exporters often use export declaration data to prepare other documents, such as a Certificate of Origin and accounting evidence.
Duties and Taxes: The Most Important Difference
Imports: Importers pay import duty based on the HS code rate plus value added tax, and some goods also carry excise tax. Taxes must be paid before goods are released unless an exemption or guarantee applies, so an incorrect HS code or value directly affects costs.
Exports: Most exported goods have no export duty, and exports qualify for 0% VAT. A correct export declaration is the key evidence for these benefits, including duty refunds on imported raw materials used to produce exported goods.
Key Checklist Before Filing a Customs Declaration
- Confirm the HS code matches the product's specifications and actual use
- Match product names, quantities, weights and values with the invoice and packing list
- Check whether the goods need an import or export permit
- Make sure Incoterms are consistent with the declared value
- Prepare a Certificate of Origin if claiming preferential duty
- Check available tax benefits, such as BOI privileges or duty refunds
- Keep copies of declarations and supporting documents for future audits
