Why this matters in 2026

Thailand remains one of ASEAN's most stable manufacturing and export hubs, with strong infrastructure through Laem Chabang and Bangkok ports, and BOI-backed industrial zones on the Eastern Seaboard.

Key considerations for supplier audits

Regulation & compliance — align product specs with buyer-country requirements early.
Supplier vetting — DBD registration, factory license (Ror.Ngor.4), and third-party audits.
Documentation — commercial invoice, packing list, CO Form A/D/E, and any product-specific certificates.
Landed cost — FOB + freight + insurance + duty + broker + last-mile.
