U.S. imports of halogenated, sulfonated & nitrated derivatives of aldehyde-function compounds (SITC 51626) totaled $41K in April 2026, traded with 6 countries.
Halogenated, Sulfonated & Nitrated Derivatives of Aldehyde-Function Compounds imports of $41K in April 2026 ran 68% below the year-to-date monthly average of $127K.
Last updated: April 2026 dataDerivatives of aldehydes, cyclic aldehyde polymers, and paraformaldehyde that have been halogenated, sulfonated, nitrated, or nitrosated occupy a specialized niche in fine chemical and agrochemical synthesis. The presence of halogen or nitro substituents often triggers additional regulatory scrutiny — including EPA Toxic Substances Control Act (TSCA) review — before these compounds can be imported for commercial use. Accurate classification requires distinguishing the parent aldehyde structure (acyclic, cyclic polymer, or paraformaldehyde) from the derivative modification, as these distinctions drive the applicable tariff line.
AI-written summary of the official U.S. Census Bureau trade figures on this page — verify before relying on it.
Yes. Under TSCA Section 13, importers must certify that chemical substances either comply with TSCA or are not subject to it. Halogenated or nitrated aldehyde derivatives that are not on the TSCA Chemical Substance Inventory may require a pre-manufacture notice (PMN) or exemption filing with the EPA before importation.
Paraformaldehyde is a solid polymeric form of formaldehyde and is classified separately from monomeric aldehydes. Its halogenated or sulfonated derivatives are grouped within this heading but must be distinguished from derivatives of acyclic aldehydes or cyclic aldehyde polymers, which may fall under different subheadings depending on the specific modification.
