U.S. exports of Nitric Acid & Sulfonitric Acids (HS 280800) totaled $2.1M in August 2026.
Importers of Nitric Acid & Sulfonitric Acids paid $96K in duties in August 2026, an average duty rate of 7.39% — duty actually collected as a share of the imports that cleared customs, not the published tariff schedule. Nitric Acid & Sulfonitric Acids imports of $1.3M in August 2026 ran 53% above the year-to-date monthly average of $853K.
Last updated: August 2026 dataNitric acid and mixed sulfonitric acids (nitrating acids) are essential intermediates in explosives, fertilizers, and specialty chemical synthesis, and the US schedule separates them at the 10-digit level into nitric acid (2808000010) and sulfonitric acids (2808000020), with a combined line (2808000000) also present. Canada is the leading supplier, consistent with integrated North American chemical trade, while Germany and South Korea serve as sources for higher-specification industrial and electronic-grade material. Both products are classified as oxidizing hazardous materials under DOT, and sulfonitric acids carry additional scrutiny given their use in nitration reactions relevant to controlled-substance precursor monitoring.

Nitric acid (2808000010) is the pure or aqueous acid used broadly in fertilizer and metal-etching applications. Sulfonitric acids (2808000020) are mixtures of nitric and sulfuric acids — commonly called 'mixed acid' or 'nitrating acid' — used specifically in nitration reactions in explosives and pharmaceutical manufacturing. Correct identification of the product form is essential because the two lines may carry different duty treatment and trigger different regulatory scrutiny.
Yes. Nitric acid above certain concentrations is subject to DHS Chemical Facility Anti-Terrorism Standards (CFATS) reporting requirements for facilities that receive it, and it appears on EPA's list of extremely hazardous substances. Importers should also be aware of ATF and international precursor-control frameworks that may require end-use certificates for certain transaction sizes, particularly for sulfonitric acid used in explosives manufacturing.
