U.S. imports of vinyl polymers in primary forms, not elsewhere specified (HS 390599) totaled $3.6M in May 2026, traded with 22 countries.
Importers of Vinyl Polymers in Primary Forms, Not Elsewhere Specified paid $270K in duties in May 2026 — an effective duty rate of 8.3% on $3.3M in dutiable value, based on actual customs collections rather than the published tariff schedule.
Last updated: May 2026 dataThe residual vinyl polymer heading covers primary-form materials that do not fit more specific vinyl polymer subheadings, including the photoconductive specialty resin polyvinyl carbazole (3905993000) and a broad catch-all for other vinyl polymers (3905998000). Polyvinyl carbazole's use in electrophotographic and organic semiconductor applications gives this heading an electronics-supply-chain dimension uncommon among commodity polymer headings. Germany leads US import supply, with Taiwan, China, and Japan also significant sources — a supplier mix that reflects both European specialty chemical production and Asian electronics-oriented polymer manufacturing.
AI-written summary of the official U.S. Census Bureau trade figures on this page — verify before relying on it.
Polyvinyl carbazole (PVK) is specifically named at the 10-digit level (3905993000) and is identified by its carbazole pendant groups, which confer photoconductive and charge-transport properties. All other vinyl polymers in primary forms not classifiable in a more specific heading fall under 3905998000. Importers should confirm the polymer's chemical identity with the manufacturer's specification sheet.
Vinyl polymers under heading 3905 from China have been subject to Section 301 tariffs, though the specific applicability depends on the tariff line and any product-specific exclusions in effect at the time of entry. Importers sourcing from China should verify current Section 301 status with a licensed customs broker before shipment.
