How to Find Factories in Thailand

Start from the product, not the city: pick the industry, then narrow by province. This directory lists 14,198 B2B suppliers across 61 provinces, 83% with a public phone number. Shortlist 5–10, check each company's DBD registration, then send the same short brief (product, annual volume, target price, timeline) to all of them.

Around Bangkok and on the Eastern Seaboard. In our data the top provinces are Bangkok (2,175), Chon Buri (2,164), Samut Prakan (1,400), Pathum Thani (1,129), Rayong (909). The three Eastern Economic Corridor provinces — Chonburi, Rayong and Chachoengsao — hold 3,448 of the 14,198 listings (24%).

Every Thai company limited is registered with the Department of Business Development (DBD) under a 13-digit juristic person number. Ask for it, then look it up on the DBD DataWarehouse (datawarehouse.dbd.go.th) to see the registered name, capital, directors and filing status. 1,483 suppliers here carry a DBD check mark, meaning we matched them to a DBD record.

Not usually. Most export-oriented Thai manufacturers have an English-speaking sales contact and quote directly. An agent helps when you need on-site quality inspection or have no time to manage several suppliers — see the direct-sourcing guide below for the process step by step.

By number of suppliers in this directory: warehouse (1,855), logistics (1,089), auto parts manufacturer (623), food manufacturer (502), steel & metal (491). Thailand is also known for automotive production, processed food exports and petrochemicals at Map Ta Phut.
