HS-4 · Heading
2511 — Natural barium sulphate (barytes); natural barium carbonate, (witherite) whether or not calcined, other than barium oxide of heading no. 2816
Chapter 25: Salt; sulphur; earths and stone
Plain-language overview
Use HS-4 2511 when importing natural barium sulphate (barytes) or natural barium carbonate (witherite). For example, if you're shipping a bulk container of barytes for industrial use, this heading applies. It covers both unprocessed and calcined forms, providing clarity on what you can import under this classification.
When deciding between HS-6 251110 and HS-6 251120, consider the specific product. If your shipment consists of natural barium sulphate, use 251110. However, if you're dealing with natural barium carbonate, whether calcined or not, then 251120 is the correct choice. Understanding these distinctions will help avoid classification errors.
The boundary between these two subheadings is defined by the chemical composition and intended use. Barium sulphate is primarily used in the paint and plastics industries, while barium carbonate is often utilized in ceramics and glassmaking. Ensure your product aligns with the intended use to select the appropriate HS-6 code.
