Thailand publishes more corporate information than many buyers realise. The Department of Business Development keeps a registry of Thai juristic persons, and much of it can be searched online. Used well, it lets you form a view of a supplier’s size, history, and finances before you’ve exchanged a single sample. That’s the core of supplier verification in Thailand, and it works best when you read the company registry record against what the supplier has told you.
Search by company name or by the 13-digit registration number. The record shows the registered name in Thai and English, the date of registration, the registered address, the business objectives, the registered capital, and the list of authorised directors. Compare each item with the supplier’s claims. A company that registered eighteen months ago, with a registered capital of one million baht, is unlikely to be a plant with 400 employees and a decade of export history, whatever the website says.
Business objectives are worth reading closely. Thai registrations often list a long set of activities, and the first few are the main ones. A company whose principal objective is wholesale trading, not manufacturing, may still produce goods through subcontractors. That isn’t improper. You just need to know it, since it changes who you audit and where the product is actually made.
Financial statements are filed annually and can often be obtained for a fee. Even a single year gives you revenue, profit or loss, assets, and liabilities. Compare revenue with claimed capacity. A supplier with stated annual sales of 15 million baht and a promise to produce an order worth that much on its own is overcommitted. Two or three years of statements show whether the business is growing, flat, or shrinking, and whether debts are rising faster than sales.
Check for Board of Investment promotion. Companies with BOI privileges have been through a screening process and hold certificates that list approved products, capacity, and activities. If a supplier mentions BOI status, ask for the certificate. If the certificate’s product list doesn’t include what they’re selling you, ask why.
Ownership deserves a look. Thailand has substantial foreign investment in manufacturing, including Japanese, Chinese, and Taiwanese-owned plants, and the registry shows the directors, though not always the ultimate owners. Knowing who stands behind the company affects decisions about pricing, raw material sourcing, and how disputes would be handled. It also helps to understand whether you’re dealing with an independent firm or a subsidiary whose decisions are made elsewhere.
Records only tell part of the story. A site visit confirms that the building at the registered address contains a working factory, with machinery, staff, and stock. The visitor should photograph the entrance, the production floor, the warehouse, and any certificates displayed. They should also check the factory operating licence and ask which products are made on site and which are bought in.
A reputable local partner can combine all of this in one report. InspectionService.com provides supplier checks in Thailand that bring the registry findings, visit notes, and photos together, which saves you from piecing it together from separate sources.
Watch for inconsistencies between names. Thai companies often trade under a brand that differs from the registered name, and a supplier may quote from one entity, ship from another, and take payment into a third. Each of these can be legitimate, but you should know about it. Check that the name on the quotation, the contract, the commercial invoice, and the bank account all match the registry entry or are explained in writing. Ask for a company affidavit, a certified document from the registry confirming directors, capital, and address as of a recent date. Banks and customs brokers often request the same document, so having it on file is useful beyond the verification itself. Request a fresh copy for each new supplier, because a certificate that is a year old can miss a change of director or address.
Finally, speak to existing customers where you can. A supplier audit confident in their record will provide names. Ask about on-time delivery, defect rates, and how the company handled its last quality complaint. The answer to that last question usually says more than the glossy brochure.
