Thai Union — world #1 canned tuna — FZ enables Pacific tuna raw imports at 0% duty for processing & re-export to US/EU. — paired with Map Ta Phut Industrial Estate (Rayong), Deep-sea LNG terminal + integrated cracker — feedstock-to-polymer within one fence, plus 13-yr EEC CIT means Raw input duty drawback 100% under FZ §155 + zero-rated VAT.
Rules: MFN 30–60% · VAT 0% on FZ-to-FZ + export zero-rated; domestic 7% if released · No excise applies · Control authority: FDA (อย.) + DOF + Halal Certification (HBCT) + USDA/EU establishment number · Best FTA: Thailand-Japan JTEPA tuna quota · EU GSP+ pending · RCEP.
Common HS-6 lines: 1604 canned tuna · 1605 prepared shrimp · 1602 prepared poultry — NYC Visa builds the FTA Origin Strategy before FZ entry to maximise duty saving.
Common pitfall: USDA FSIS establishment number must match the FZ-located plant — re-audit (6 months) required if moved between FZs. — we pre-load the mitigation checklist + audit trail for Customs' 5-yr ex-post audit.
