U.S. imports of unsaturated chlorinated derivatives of acyclic hydrocarbons, n.e.s. (SITC 51134) totaled $7.0M in April 2026, traded with 12 countries.
Importers of Unsaturated Chlorinated Derivatives of Acyclic Hydrocarbons, N.E.S. paid $755K in duties in April 2026 — an effective duty rate of 11% on $6.9M in dutiable value, based on actual customs collections rather than the published tariff schedule.
Last updated: April 2026 dataUnsaturated chlorinated acyclic derivatives not elsewhere specified form a residual grouping that captures specialty chlorinated monomers, intermediates, and reagents whose carbon chain contains at least one double or triple bond. Vinyl chloride monomer (VCM), for example, falls within the broader unsaturated chlorinated family, though major commodity volumes are typically classified at more specific headings. Importers classifying under this residual code should confirm that no more specific SITC or HTS provision applies, as misclassification between saturated and unsaturated series can trigger duty discrepancies.

The key structural criterion is the presence of a carbon-carbon double or triple bond in the acyclic chain. Compounds with only single carbon-carbon bonds are classified under the saturated residual (SITC 51136), while those retaining unsaturation fall here. Laboratory analysis or a supplier's certificate of analysis confirming molecular structure is typically required to support the classification.
All chemical substances imported into the US must comply with TSCA. For residual 'N.E.S.' categories, importers should verify that each specific substance is listed on the TSCA Chemical Substance Inventory and file the appropriate TSCA import certification at entry. Substances not on the Inventory may require a pre-manufacture notice or exemption before import.
