Thai kratom is a vendor name historically tied to Thailand, now used as a trade label across vein colors rather than a guarantee of Thai origin. Thailand long restricted kratom and only legalized it in 2021, so most “Thai” kratom on the US market is grown elsewhere in Southeast Asia.
The label is applied to red, green, and white products. Because it functions as a market category, vein color and lab testing describe a batch more reliably than the origin name. See the Kratom Strains Guide.
