About this directory
Manufacturer listings here come from public Google Business Profiles filtered against a B2C category blocklist (retail stores, restaurants, factory outlet malls are excluded). Each listing shows direct contact (phone + website where available) so buyers can skip sourcing-agent markups when contracts allow.
Manufacturer — FAQ
How do I contact a Thai manufacturer directly?⌄
Each listing shows the manufacturer's public phone and website where available. We never paywall or gatekeep contact info. Many buyers go through sourcing agents who add 15-30% markup — direct contact saves margin and gives you control of the relationship.
What does the Trust Score mean for a manufacturer?⌄
Trust Score (0-100) combines Google rating and review volume on a logarithmic scale. Higher score = larger, more established operation with more public reviews. It's a directional signal — pair it with direct due diligence (factory visits, samples, references).
Are Thai manufacturers DBD-verified?⌄
DBD-verified suppliers on this directory have been cross-checked with Thailand's Department of Business Development (Ministry of Commerce). Verified profiles show the official legal name, registration number, registered capital, founding date, and TSIC industry code. Non-verified listings are sourced from Google Business Profiles and may still be legitimate operating businesses.
