Last updated: August 2026 dataElemental calcium metal, classified under 2805120000, functions primarily as a reducing agent in the production of rare earth metals, uranium, and specialty alloys, and as a desulfurization and deoxidation agent in steelmaking. China is the dominant global producer and the leading US import source, a concentration that exposes buyers to Section 301 tariff considerations when sourcing Chinese-origin material. Mexico and Japan also supply the US market. Like other alkaline-earth metals, calcium reacts with moisture and must be handled under inert conditions, requiring DOT-compliant packaging for import shipments.

Heading 280512 covers only the pure elemental metal — calcium in its unalloyed, reduced form. Calcium compounds such as calcium carbonate, calcium chloride, or calcium oxide are classified in other headings of Chapters 25 or 28. The key classification question is whether the product is the free metal or a chemical compound.
Chinese-origin calcium metal may be subject to Section 301 tariffs. Importers should verify the current Section 301 list status for the applicable HTS line and confirm whether any exclusions apply, as the lists and exclusion processes have been updated periodically. Consulting a licensed customs broker before purchase is advisable.
