Legal · Translation · Visa Services for Manufacturers in Thailand
Manufacturing contributes more than 27% of Thai GDP and operates inside overlapping layers of regulation — the Factory Act, BOI investment promotion, EEC privileges, FTA rules of origin and customs declarations in multiple languages. NYC Legal & Notary Services acts as your one-stop compliance partner from BOI application to port-of-loading customs clearance.
Challenges this sector faces
Multilingual ISO & audit documentation
Japanese, German and Chinese off-takers demand ISO 9001 / 14001 / 45001 documentation in their native language, certified by a qualified translator. In-house translations rarely pass third-party audits.
BOI privileges & tax holidays
BOI applications require a Feasibility Study, investment plan and parent-company documents legalised via Apostille or consular chain. A single missing step can cost you a 5–8 year corporate-income-tax holiday.
Customs & FTA documentation
Certificate of Origin, invoices and packing lists must reconcile across languages. Foreign-issued documents that have not been MFA-legalised in Thailand can be rejected at customs, generating tens of thousands of baht in demurrage per day.
Work permits for foreign engineers
Plants running Japanese or German technology routinely bring in expat engineers. Non-B + Work Permit applications require translated and legalised diplomas, employment letters and BOI sub-approvals.
How NYC Legal helps
ISO & technical translation
Our translation team pairs mechanical, electrical and chemical engineers with linguists, so terminology matches DIN/JIS/ASTM standards rather than dictionary equivalents.
End-to-end BOI application
Pre-screening, feasibility drafting, online filing, follow-up until the Promotion Certificate is issued, then onward Non-B and Work Permit processing for foreign management.
MFA + embassy legalization
We legalise parent-company documents (Certificate of Incorporation, Board Resolutions, POAs) for Thai use, and Thai documents for outbound shipments to your buyers.
