U.S. imports of salts of inorganic acids and peroxoacids (excluding azides) (HS 284290) totaled $19.6M in July 2026, traded with 20 countries.
Importers of Salts of Inorganic Acids and Peroxoacids (Excluding Azides) paid $2.1M in duties in July 2026 — an effective duty rate of 15% on $14.2M in dutiable value, based on actual customs collections rather than the published tariff schedule.
Last updated: July 2026 dataFulminates, cyanates, thiocyanates, selenides, tellurides, and other miscellaneous inorganic acid salts fall under this heading, which excludes azides covered elsewhere in Chapter 28. The US schedule breaks these out across four 10-digit lines — 2842901000 for fulminates, cyanates, and thiocyanates, and 2842909010 and 2842909050 for selenides/tellurides and remaining salts respectively — reflecting the chemical diversity of the group. Germany and Canada are the leading suppliers, with China also a significant source; goods from China may be subject to Section 301 tariffs. Importers should confirm correct classification at the 10-digit level, as the chemical identity of the salt determines which line applies.

Classification hinges on the specific anion: if the salt is a selenide or telluride, it falls under 2842909010. All other inorganic acid or peroxoacid salts not covered by a more specific line in the heading — and not azides — default to 2842909050. A licensed customs broker or CBP binding ruling can confirm the correct line for novel or ambiguous compounds.
Imports originating from China may be subject to Section 301 tariffs, depending on the specific 10-digit classification. Importers should verify current Section 301 list applicability for each tariff line before entry.
