HS 280800

Nitric Acid & Sulfonitric Acids

U.S. imports of nitric acid & sulfonitric acids (HS 280800) totaled $817K in April 2026, traded with 10 countries.

Last updated: April 2026 data

Nitric acid and mixed sulfonitric acids — used in explosives manufacturing, fertilizer production, metal etching, and pharmaceutical synthesis — are split at the 10-digit level into nitric acid (2808000010) and sulfonitric acids (2808000020). Canada is the primary US supplier, with Germany and South Korea serving as important sources for high-purity and specialty grades. Both substances are classified as oxidizing hazardous materials under DOT regulations, and sulfonitric acid mixtures (used in nitration reactions) carry additional handling complexity due to their combined corrosive and oxidizing properties.

Frequently Asked Questions

How are nitric acid and sulfonitric acids classified differently under the US tariff schedule?

The US schedule provides separate 10-digit lines: 2808000010 for nitric acid and 2808000020 for sulfonitric acids (mixed nitric-sulfuric acid). Correct classification depends on the product's composition, and importers should obtain a certificate of analysis to confirm whether the shipment is a pure acid or a mixed acid blend.

What countries are the leading sources of nitric acid and sulfonitric acid imports into the US?

Canada is the top supplier, followed by Germany and South Korea. Taiwan and Japan also appear among the leading sources. The supplier mix reflects both proximity and the availability of specialty grades for electronics and pharmaceutical applications.
