Last updated: May 2026 dataBarium carbonate (BaCO₃) is a key industrial chemical used primarily in the ceramics and glass industries to reduce soluble barium compounds and improve glaze quality, and in the production of specialty barium salts. Germany leads US import supply, followed by India and Italy, reflecting established European and South Asian chemical manufacturing capacity. Classifying under the single 10-digit line 2836600000, it presents a straightforward tariff structure, though importers should verify whether Section 301 exposure applies to shipments from China, which rounds out the top five suppliers.
AI-written summary of the official U.S. Census Bureau trade figures on this page — verify before relying on it.
Barium carbonate is specifically the salt of carbonic acid with barium and classifies under 2836600000. Other barium compounds — such as barium sulfate, barium chloride, or barium oxide — fall under entirely different HTS headings. The key classification test is the anion: carbonate versus sulfate, halide, or oxide.
Imports of barium carbonate from China may be subject to Section 301 tariffs. Importers should confirm the current applicability and any exclusion orders with a licensed customs broker before shipment, as Section 301 coverage and exclusions are periodically revised.
