Last updated: July 2026 dataBarium sulfate enters US commerce primarily as a high-brightness filler for paints, coatings, plastics, and X-ray contrast media, with Germany and Italy among the leading suppliers. The entire heading resolves to a single tariff line, 2833270000, simplifying classification but placing emphasis on end-use documentation when pharmaceutical-grade material (used as a radiopaque agent) is involved. Natural barium sulfate (barite) is classified elsewhere, so the processing method—precipitation or grinding—is the key distinction at the border.

Natural barite (barium sulfate ore) is classified in Chapter 25 as a mineral, while chemically precipitated or refined barium sulfate falls under 2833270000 in Chapter 28. The key factor is whether the material has been chemically processed rather than merely crushed or ground.
Yes. Barium sulfate formulated as a contrast medium for medical imaging is regulated by FDA as a drug product and requires compliance with FDA import admissibility procedures, including review against approved drug applications, in addition to standard customs entry.
