SITCSection 5
U.S. imports of acyclic amides, carbamates & derivatives; salts (SITC 51471) totaled $36.5M in April 2026, traded with 34 countries.
Importers of Acyclic Amides, Carbamates & Derivatives; Salts paid $2.6M in duties in April 2026 — an effective duty rate of 8.3% on $31.7M in dutiable value, based on actual customs collections rather than the published tariff schedule.
Last updated: April 2026 dataAcyclic amides — including acyclic carbamates — and their derivatives form a commercially significant class of nitrogen-function compounds used in agrochemical formulations, polymer production, and pharmaceutical synthesis. Carbamate derivatives in particular are key active ingredients or precursors in pesticide chemistry, which can affect admissibility requirements depending on end-use. The open-chain (acyclic) structure is the primary classification criterion separating these substances from cyclic amide counterparts, and importers should confirm ring-structure absence in technical documentation to avoid heading disputes.
AI-written summary of the official U.S. Census Bureau trade figures on this page — verify before relying on it.
CBP relies on the compound's structural formula to confirm the absence of a ring structure. If a compound contains even one ring — carbocyclic or heterocyclic — it falls outside this heading and into the cyclic amide provisions. Submitting a certified structural diagram or IUPAC name with the entry documentation helps prevent disputes.
Carbamate compounds intended for use as pesticide active ingredients or precursors may require EPA registration review and are subject to FIFRA import provisions. Importers should verify whether the specific compound triggers EPA admissibility requirements before shipment.
