U.S. imports of Natural Barium Sulfate (Barytes) (HS 251110) totaled $35.2M in August 2026, imported from 16 countries.
Importers of Natural Barium Sulfate (Barytes) paid $126K in duties in August 2026, an average duty rate of 0.44% — duty actually collected as a share of the imports that cleared customs, not the published tariff schedule. Natural Barium Sulfate (Barytes) imports of $35.2M in August 2026 ran 67% above the year-to-date monthly average of $21.1M.
Last updated: August 2026 dataBarytes — the naturally occurring mineral form of barium sulfate — is a high-density, chemically inert industrial mineral whose dominant use is as a weighting agent in oil and gas drilling fluids, where its specific gravity is critical to wellbore pressure control. The US tariff schedule distinguishes ground barytes (2511101000) from unground material (2511105000), reflecting the significant value-add of milling to API-grade particle specifications required by the drilling industry. Importers should be aware that API Specification 13A sets the purity and particle-size standards that determine whether a shipment qualifies for drilling-grade pricing.

Drilling-grade barytes must conform to API Specification 13A, which sets minimum specific gravity (typically 4.20 g/cm³), maximum soluble alkaline earth metals, and particle-size distribution requirements. Material that does not meet these thresholds is typically redirected to paint, coatings, or rubber applications.
Ground barytes (2511101000) and unground barytes (2511105000) are assessed separately under the US tariff schedule. Since grinding to API-grade specification is a substantial processing step, importers should ensure the product's physical form and particle-size documentation align with the declared tariff line to avoid reclassification at the port of entry.
