Importers of Chemical Products & Preparations, N.E.S. paid $50.5M in duties in April 2026 — an effective duty rate of 14% on $373.2M in dutiable value, based on actual customs collections rather than the published tariff schedule.
Last updated: April 2026 dataResidual chemical products and preparations not elsewhere specified serve as a catch-all for formulated substances that do not fit more specific SITC headings—a classification that customs authorities scrutinize carefully to prevent misuse as a default category. Because the composition of goods in this heading varies widely, TSCA certification requirements apply broadly, and some formulations may additionally trigger EPA or OSHA hazard-communication obligations. Importers relying on this heading should maintain detailed Safety Data Sheets and technical specifications to support classification decisions and respond to any CBP requests for further information.

The NES designation is a residual category, and CBP may question whether a product genuinely lacks a more specific classification or is being placed here to avoid a higher duty rate or regulatory requirement. Importers should document why no more specific heading applies, supported by technical data sheets and Safety Data Sheets, and be prepared to provide laboratory analysis if requested.
All chemical substances imported into the US must comply with TSCA unless specifically exempt. Importers must certify at entry that each chemical substance in the preparation is either on the TSCA Chemical Substance Inventory or subject to an applicable exemption or notification. Given the heterogeneous nature of NES preparations, a substance-by-substance review of the formulation against the TSCA inventory is strongly recommended before shipment.
