Last updated: August 2026 dataUnwrought antimony metal and antimony powders serve as flame-retardant synergists (typically as antimony trioxide precursors), lead-acid battery hardeners, and semiconductor dopants. Thailand leads US imports under this heading, followed by India and Burma, reflecting the geographic concentration of antimony smelting capacity in Southeast Asia. Antimony is classified as a critical mineral by the US government, and supply-chain concentration in this region has drawn increasing attention from importers seeking to diversify sourcing.

Antimony is on the US critical minerals list, but that designation does not by itself impose import restrictions or additional entry procedures. Standard CBP entry requirements apply. However, importers should monitor any evolving trade remedy actions or export restrictions imposed by major producing countries, as supply disruptions in this concentrated market can affect availability and pricing.
Unwrought antimony (heading 8110) refers to the metal itself in primary forms — ingots, lumps, or powders of the element — while antimony trioxide and other antimony compounds are classified in Chapter 28 as inorganic chemicals. The key distinction is whether the imported material is the metal or a chemical compound. Importers should obtain a certificate of analysis confirming the form and purity of the material to support the correct classification.
