SITCSection 5
U.S. imports of ammonia, anhydrous or in aqueous solution (SITC 52261) totaled $114.6M in April 2026, traded with 10 countries.
Importers of Ammonia, Anhydrous or in Aqueous Solution paid $2.3M in duties in April 2026 — an effective duty rate of 9.9% on $23.5M in dutiable value, based on actual customs collections rather than the published tariff schedule.
Last updated: April 2026 dataAnhydrous ammonia and aqueous ammonia solution (ammonium hydroxide) are foundational nitrogen-source chemicals serving fertilizer production, refrigeration systems, water treatment, and chemical synthesis. Anhydrous ammonia is classified as a hazardous material under DOT regulations and requires specialized pressure vessels for transport, while aqueous solution is handled under less stringent conditions — a distinction that drives significant differences in logistics cost and carrier requirements. The fertilizer sector is the dominant end-use, making import volumes sensitive to domestic natural gas prices, which govern US production economics and influence the competitiveness of imported supply.

Anhydrous ammonia is a compressed liquefied gas classified as a hazardous material (Hazard Class 2.2/2.3) requiring DOT-specification pressure vessels and placarding, while aqueous ammonia solutions at lower concentrations may be transported under less restrictive conditions. Importers and logistics providers must confirm the concentration and physical state of the product to apply the correct DOT shipping requirements and select appropriate carriers.
Ammonia is produced via the Haber-Bosch process using natural gas as the primary feedstock, so US domestic production costs track natural gas prices closely. When US natural gas prices are relatively high, imported ammonia becomes more price-competitive, increasing import volumes; when domestic gas is cheap, US producers can undercut import prices. This dynamic makes ammonia one of the more price-sensitive commodity chemicals in the import market.
