HS 251110 · Natural barytes (barium sulphate)
Get the code right at quotation time, not at customs.
Misclassifying HS 251110 on the commercial invoice walks the cargo into the wrong duty rate, the wrong rebate column, and a customs hold that costs days of demurrage to clear. This page gives you the WCO heading, the product it most often covers, the China VAT export rebate rate, the US Section 301 status, the supplier provinces that ship it, and practitioner buying notes for first-time importers.
For an explanation of how the WCO Harmonized System is structured, what each digit means, and why misclassification is the most common landed-cost error first-time buyers make, see the HS code glossary entry.

Buying notes
Natural barium sulfate (BaSO4) for oilfield drilling-mud weighting and downstream barium-chemistry feedstock. Guangxi and Guizhou hold the bulk of Chinese barytes mining. Specific gravity (typically 4.2 minimum, API 13A standard) and brightness drive the price; oilfield-grade is the largest single global pull. Section 301 not currently listed. The post-2022 oil-and-gas drilling rebound supports steady demand.
Common end uses
