Working with Thai factories for cosmetici a marchio privato turned out to be my biggest unexpected discovery last year. Initially, Southeast Asia was not on my radar at all. That changed when a friend running a spa brand sent me OEM samples — their skin feel was nothing like the “cheap contract manufacturing” I had in mind.
I later learned that Thailand’s contract‑manufacturing history goes back much further than most people realize. Back in the 1970s, local factories already held production licenses for Colgate. What’s more, access to Halal certification and ASEAN‑sourced botanical ingredients are unique advantages hard to find elsewhere.
After visiting multiple facilities, I shortlisted the following seven local Thai factories based on product portfolio, certification systems and production capacity. All of them accept direct orders.
