U.S. imports of Hydrazine and Hydroxylamine and Their Inorganic Salts (SITC 52268) totaled $3.7M in August 2026, imported from 10 countries.
Importers of Hydrazine and Hydroxylamine and Their Inorganic Salts paid $423K in duties in August 2026, an average duty rate of 11.47% — duty actually collected as a share of the imports that cleared customs, not the published tariff schedule. Hydrazine and Hydroxylamine and Their Inorganic Salts imports of $3.7M in August 2026 ran 36% above the year-to-date monthly average of $2.7M.
Last updated: August 2026 dataHydrazine and hydroxylamine are reactive nitrogen-hydrogen compounds with critical roles in pharmaceutical synthesis, agrochemical production, rocket propellants, and corrosion inhibitors for boiler water treatment. Both substances and their inorganic salts — such as hydroxylamine sulfate and hydrazine sulfate — are subject to stringent hazardous-materials transport regulations given their flammability, toxicity, and potential use as precursor chemicals. EPA TSCA reporting obligations and, in some cases, export-control considerations at the country of origin add compliance layers that importers should address before contracting supply.

Hydrazine and its aqueous solutions are classified as flammable liquids and toxic substances under DOT 49 CFR, requiring proper UN-number labeling, placarding, and compatibility with approved packaging types. Ocean shipments must comply with IMDG Code requirements, and importers should confirm that the foreign shipper's dangerous-goods declaration matches the concentration and form of the product.
While hydroxylamine salts are not currently DEA-scheduled precursors, they are monitored under EPA TSCA and may be subject to reporting requirements if imported above certain volume thresholds. Importers should also check whether the country of export imposes export-license requirements, as some jurisdictions control these compounds due to their use in energetic material synthesis.
