Products classified under Tariff item 2511.10
Barytes Lump for Grinding
Lump form natural barium sulphate ore suitable for further grinding into powder, sourced from barytes deposits. The product is in the crude state, which is covered by Chapter 25 Note 1, and has not been subjected to any processing beyond mining and sorting.
2511.10.00Blizzard Ground Barytes Paint Grade
Premium white ground natural barium sulphate (barytes) for architectural paints, offering superior whiteness and low oil absorption. The product is processed only by grinding, which is permitted under Chapter 25 Note 1, and is not mixed or otherwise altered beyond that.
2511.10.00Calcined Ground Witherite for Ceramics
Lightly calcined and ground natural witherite (barium carbonate) for ceramic glazes and frits. The calcination is not to barium oxide, so it remains under heading 25.11, and the product is not subjected to processing beyond that allowed by Chapter 25 Note 1.
