Last updated: August 2026 dataAntimony articles not elsewhere specified — including refined metal, oxides used as flame retardants, and specialty compounds — enter under the single 10-digit line 8110900000. Cambodia leads US import supply for this heading, followed by the United Kingdom and Peru, a geographically diverse sourcing pattern that reflects both primary smelting capacity and downstream processing. Antimony is a US-designated critical mineral, making supply-chain provenance documentation increasingly important for downstream manufacturers in electronics, plastics, and battery sectors.

Cambodia's position likely reflects re-export or further processing of antimony sourced regionally, a common pattern for specialty metals where value-added finishing or blending occurs in a country other than the original mine source. Importers should verify origin documentation carefully, as country-of-origin rules for processed metals can be complex.
Unwrought antimony metal and antimony powders fall under heading 8110, while antimony trioxide — the dominant commercial form used as a flame-retardant synergist — is classified as an inorganic chemical compound under Chapter 28. Misclassification between these chapters is a common audit finding; consult a licensed customs broker to confirm the correct heading for your specific product form.
