Acrylonitrile-Butadiene-Styrene (ABS) Copolymers in Primary Forms

ABS imports from China have been subject to Section 301 tariffs, making accurate country-of-origin documentation critical. A manufacturer's declaration, certificate of origin, and production records may all be required to substantiate origin claims. Importers sourcing from alternative countries should ensure documentation clearly establishes that the resin was produced — not merely transshipped — in the declared origin country.

Melt flow index, impact strength (notched Izod), heat deflection temperature, and flame-retardant additive content are the primary commercial specifications. Flame-retardant ABS grades may carry additional regulatory considerations under RoHS or REACH in export markets, which can affect the choice of grade and supplier for globally distributed finished goods.
