More Specific Codes
This product may fall under a more specific subheading:
Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If the product is natural barium carbonate (witherite) rather than sulphate
The heading covers both natural barium sulphate and natural barium carbonate, but they are separate tariff items.
If the product is precipitated or chemically treated barium sulphate
Chemically precipitated barium sulphate is classified as a chemical product, not a natural mineral.
Not sure which classification is right?
The Tariff Assistant works through the GRI rules on your specific product to reach the right tariff item — and can price the duty on it in the same conversation.
Import Tips & Compliance
• Ensure the product is natural (not synthetic) barium sulphate; provide a certificate of analysis showing density and purity to support classification
• Keep records of the grinding process to demonstrate it is within chapter 25 processing limits
• Verify if a Canadian Standards Association (CSA) or API certification is required by your buyer

Barytes for Paint Extender
Barytes for Paint Extender is natural barium sulphate ground to a specific particle size for use as an extender pigment in architectural paints, improving opacity and durability. It qualifies under tariff item 2511.10.00 because it is a natural product processed only by mechanical means (grinding, classification) without chemical modification.
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.
Blended Barytes-Witherite Mix
Blended Barytes-Witherite Mix is a natural mixture of barium sulphate and barium carbonate from the same deposit, ground for metallurgical flux applications. It falls under tariff item 2511.10.00 as a natural barium sulphate product, provided the mixture is not artificially blended beyond natural occurrence.
Blizzard 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.
Calcined 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.
Calcined Witherite Powder
Calcined Witherite Powder is natural barium carbonate ore that has been calcined to remove impurities and ground into powder for glass manufacturing and chemical feedstock. It falls under tariff item 2511.10.00 because chapter note 1 permits calcination for witherite, and the product remains a natural mineral.
