U.S. imports of Salts of Inorganic Acids or Peroxoacids, N.E.S. (SITC 52389) totaled $40.7M in August 2026, imported from 29 countries.
Importers of Salts of Inorganic Acids or Peroxoacids, N.E.S. paid $7.5M in duties in August 2026, an average duty rate of 18.28% — duty actually collected as a share of the imports that cleared customs, not the published tariff schedule. Salts of Inorganic Acids or Peroxoacids, N.E.S. imports of $40.7M in August 2026 ran 32% above the year-to-date monthly average of $30.9M.
Last updated: August 2026 dataClassified as a residual 'not elsewhere specified' heading, this group captures inorganic acid salts that do not fit the more specific SITC positions for cyanides, silicates, borates, or oxometallic salts — examples include nitrites, selenates, tellurates, arsenates, and peroxocarbonates. Because the heading is a catch-all, correct classification requires ruling out all more-specific positions before assigning goods here, making chemical identity documentation especially important. Many compounds in this group serve as specialty reagents, water-treatment chemicals, or precursors in pharmaceutical and electronics manufacturing.

A supplier-issued certificate of analysis or safety data sheet identifying the precise chemical formula is the starting point. The importer or broker should then systematically check whether the compound fits any named SITC heading (cyanides, silicates, borates, oxometallic salts, etc.) before defaulting to the NES position. Customs may request this analysis during a classification review.
Potentially yes — certain inorganic salts, such as sodium nitrite, have been subject to antidumping or countervailing duty orders at various times. Because the heading is broad, importers should check the current scope of any active orders against the specific compound and its country of origin before entry.
