U.S. imports of polymers of other halogenated olefins, in primary forms (HS 390490) totaled $950K in April 2026, traded with 15 countries.
Importers of Polymers of Other Halogenated Olefins, in Primary Forms paid $152K in duties in April 2026 — an effective duty rate of 16% on $953K in dutiable value, based on actual customs collections rather than the published tariff schedule. Polymers of Other Halogenated Olefins, in Primary Forms imports of $950K in April 2026 ran 30% below the year-to-date monthly average of $1.3M.
Last updated: April 2026 dataPolymers of halogenated olefins not elsewhere specified occupy a technically demanding niche, encompassing materials such as polychlorotrifluoroethylene (PCTFE) and related specialty halogenated resins used in barrier packaging, cryogenic seals, and electrical insulation. The US tariff schedule now subdivides this heading into elastomeric (3904901000) and non-elastomeric (3904905000) grades, with a legacy undivided line (3904900000) also present. Japan and the Netherlands are the leading sources of US imports under this heading, with South Korea and Germany also contributing meaningfully to supply.
AI-written summary of the official U.S. Census Bureau trade figures on this page — verify before relying on it.
The elastomeric line (3904901000) covers halogenated olefin polymers that behave like rubbers — flexible and recoverable under deformation — while the non-elastomeric line (3904905000) covers rigid or semi-rigid grades. Correct classification requires review of the polymer's physical properties and, where ambiguous, a binding ruling request to CBP.
The undivided line (3904900000) predates the elastomeric/non-elastomeric split and may still appear on older entry documents or for goods that do not clearly fit either subdivision. Importers should use the most specific applicable line; if classification is uncertain, a licensed customs broker can advise on the appropriate line given current CBP guidance.
