U.S. imports of natural barium sulfate (barytes) & natural barium carbonate (witherite) (SITC 27892) totaled $15.6M in July 2026, traded with 14 countries.
Importers of Natural Barium Sulfate (Barytes) & Natural Barium Carbonate (Witherite) paid $128K in duties in July 2026 — an effective duty rate of 2.3% on $5.7M in dutiable value, based on actual customs collections rather than the published tariff schedule. Natural Barium Sulfate (Barytes) & Natural Barium Carbonate (Witherite) imports of $15.6M in July 2026 ran 18% below the year-to-date monthly average of $19.1M.
Last updated: July 2026 dataBarytes — natural barium sulfate — is the dominant commercial mineral in this heading, valued for its high specific gravity and chemical inertness in oilfield drilling mud, radiation shielding, and automotive brake linings. Witherite (natural barium carbonate) is far less common in trade and must be distinguished from chemically precipitated barium carbonate, which falls under a separate chemical heading. The oilfield services sector is the largest consumer of imported barytes, and API specifications for drilling-grade material govern acceptable density and chemical purity thresholds.

The American Petroleum Institute (API) publishes specifications for drilling-grade barite, including minimum specific gravity, maximum soluble alkaline earth metals, and maximum residue on sieve. Importers supplying the oilfield sector must ensure their material meets current API standards and typically provide third-party test certificates with each shipment.
Natural barytes is mined and may contain trace mineral impurities consistent with geological origin, while synthetic barium sulfate (blanc fixe) is chemically precipitated to high purity. The distinction matters because synthetic barium sulfate is classified under chemical headings rather than this mineral heading, and the two carry different duty rates. Mineralogical certificates or production-process declarations from the supplier support correct classification.
