Last updated: August 2026 dataBarium carbonate is a white inorganic salt used primarily as a raw material in specialty glass (including CRT and optical glass), ceramic glazes, and barium-based chemical synthesis. Classified under a single tariff line (2836600000), it is a relatively concentrated market where Germany and India are leading US suppliers, with China also a notable source — an origin mix that may implicate Section 301 tariff exposure for Chinese-origin material. Purity grade and particle size are key commercial specifications that distinguish industrial ceramic-grade from higher-purity electronic or optical-grade product.

HTS 283660 does not subdivide by purity grade — all barium carbonate falls under 2836600000 regardless of whether it is standard industrial grade (used in ceramics and bricks) or high-purity electronic grade (used in specialty glass and phosphors). Importers should document the grade and specification on commercial invoices for end-use verification and any applicable downstream regulatory purposes.
Chinese-origin barium carbonate may be subject to Section 301 tariffs. Importers should verify the current tariff treatment for the applicable HTS line and country of origin with a licensed customs broker, as Section 301 lists and rates have been subject to revision.
