U.S. imports of Phosphates, N.E.S. (SITC 52363) totaled $18.8M in August 2026, imported from 36 countries.
Importers of Phosphates, N.E.S. paid $2.6M in duties in August 2026, an average duty rate of 14.09% — duty actually collected as a share of the imports that cleared customs, not the published tariff schedule. Phosphates, N.E.S. imports of $18.8M in August 2026 ran 22% below the year-to-date monthly average of $24.2M.
Last updated: August 2026 dataPhosphates not elsewhere specified under SITC 52363 encompass a broad set of inorganic phosphate salts — including mono- and di-calcium phosphate, zinc phosphate, and various ammonium phosphates — that do not fall under the dedicated sodium tripolyphosphate or polyphosphate headings. These compounds are critical inputs for animal feed supplements, metal surface treatment, dental materials, and food processing. Correct classification requires distinguishing the specific cation and degree of phosphate condensation, as several related compounds carry their own dedicated SITC codes.

Sodium tripolyphosphate (52364) and polyphosphates NES (52365) have their own headings, so 52363 applies to orthophosphates and other phosphate salts not captured there. The key classification variables are the cation (calcium, zinc, ammonium, etc.) and whether the compound is a condensed polyphosphate or a simple orthophosphate salt.
Certain phosphate compounds — particularly diammonium phosphate and monoammonium phosphate from specific origins — have historically been subject to antidumping or countervailing duty investigations. Importers should verify current order status with the Commerce Department and confirm the precise chemical identity and country of origin before entry.
