How to fix the HS code, check tariffs and import requirements, and use free trade agreement preferences.
Updated 2026-11-12
Scope:Companies preparing to export goods.
Overview
Classification drives the duty rate, import licences and certification; origin decides whether FTA preferences apply. Getting either wrong can lead to back duties, penalties or clearance delays.
Key concepts
- HS code: the first 6 digits are international; countries extend to 8 or 10 digits.
- MFN vs preferential rates: preferential rates apply only when rules of origin are met.
- Rules of origin: common tests are wholly obtained, change in tariff classification and regional value content.
- Proof of origin: certificates from an issuing body or approved-exporter declarations, per each agreement.
Steps
- Determine the 6-digit HS code from composition, function and use.
- Check the destination’s national code, duty rate and import controls with its customs.
- Check certification, labelling and SPS requirements.
- Identify FTAs both China and the destination belong to (e.g. ASEAN–China FTA, RCEP).
- Test the product against the agreement’s product-specific rules.
- Obtain a certificate or prepare a declaration, and keep cost and production records.
Documents
- Product description, composition and process flow
- Bill of materials and sourcing
- Cost records for value-content calculations
Common limitations
- National subheadings can differ between countries for the same product.
- Minimal processing usually does not confer origin.
Practical notes
Main FTAs per country are in Compare · Trade. For complex goods, consider an advance ruling from the destination’s customs.
