1-Chloro-2,3-Epoxypropane (Epichlorohydrin)

Both countries host large integrated epoxy resin and chemical manufacturing complexes that produce epichlorohydrin as part of broader value chains. Thailand in particular benefits from access to bio-based glycerin feedstock, enabling glycerin-to-epichlorohydrin routes that compete with propylene-based production.

Epichlorohydrin is listed on the TSCA Chemical Substance Inventory, so importers must certify compliance at entry — either that the substance is on the inventory or that it qualifies for an exemption. Additionally, EPA has identified it as a chemical of concern, so importers should monitor any ongoing TSCA risk evaluation actions that could impose use or import restrictions.
