About Duty Rates: Rates are divided into Column 1 and Column 2. Column 1 is subdivided into General (normal trade relations rates for all countries not eligible for special programs) and Special (preferential rates for countries with free trade agreements or preference programs). Column 2 rates apply to products from Cuba, North Korea, Belarus, and Russia. When no special rate exists for a classification, General rates apply.

Overview

This HTS category, 3903.20.00.00, specifically covers styrene-acrylonitrile (SAN) copolymers in their primary forms. SAN copolymers are thermoplastic polymers characterized by their transparency, rigidity, and good chemical resistance. They are formed by the copolymerization of styrene and acrylonitrile monomers. Common applications include housewares, packaging, appliance components, and automotive parts where a balance of properties between polystyrene and acrylonitrile butadiene styrene (ABS) is desired.

It is important to distinguish this classification from its siblings. While all fall under "Polymers of styrene, in primary forms," 3903.20.00.00 is distinct from "Polystyrene" (3903.10), which refers to homopolymers of styrene. Furthermore, it is separate from "Acrylonitrile-butadiene-styrene (ABS) copolymers" (3903.30.00.00), which contain a butadiene rubber component that imparts toughness. "Other" copolymers of styrene (3903.90) would encompass materials with styrene and monomers other than acrylonitrile or butadiene.

As this is a leaf node within the HTS classification system, there are no further subcategories for 3903.20.00.00. Classification at this level is determined by the presence of both styrene and acrylonitrile as the primary monomers forming the copolymer. The physical form (e.g., beads, granules, powders) is also relevant for primary forms.
