U.S. exports of Vinyl Chloride Copolymers (N.E.S.), Primary Forms (SITC 57392) totaled $8.2M in August 2026.
Importers of Vinyl Chloride Copolymers (N.E.S.), Primary Forms paid $60K in duties in August 2026, an average duty rate of 1.15% — duty actually collected as a share of the imports that cleared customs, not the published tariff schedule.
Last updated: August 2026 dataVinyl chloride copolymers not elsewhere specified capture specialty polymer grades — such as vinyl chloride–ethylene or vinyl chloride–propylene copolymers — that do not fit the vinyl acetate or vinylidene chloride categories. The 'N.E.S.' designation means classification here is residual: importers must document why the material falls outside the more specific copolymer headings. These specialty grades serve niche applications in barrier packaging, specialty coatings, and engineering compounds.

A binding ruling request or a detailed technical data sheet showing the comonomer identity and weight percentages is advisable. The importer should demonstrate that the product does not meet the definition of vinyl chloride–vinyl acetate copolymers (57391) or vinylidene chloride polymers (57393) before defaulting to the N.E.S. category.
The N.E.S. heading may carry a different HTS subheading and duty rate than the named copolymer categories. Because rates and Section 301 applicability can differ by specific subheading, confirming the correct classification with a licensed customs broker before importation is essential.
