HS Code for Natural barium carbonate
Natural barium carbonate, known mineralogically as witherite, is classified under HS code 2511.20. This classification is determined by its status as a raw mineral product within Chapter 25, which covers salt, sulfur, earths, and stone. The heading 2511 is divided into two subheadings: 2511.10 for the sulphate and 2511.20 for the carbonate. To qualify for this code, the material must be naturally occurring witherite. It can be in its crude state or calcined (heated to remove volatile substances), provided it has not undergone extensive chemical processing that would transform it into a pure chemical compound. Witherite is a relatively rare mineral but is industrially significant. It is primarily used in the glass industry to increase the refractive index of glass, in the production of ceramics to prevent efflorescence, and as a precursor for other barium chemicals. If the product is chemically synthesized through precipitation, it moves to Chapter 28, making the natural origin the primary driver for this specific HS code. The classification 2511.20 specifically excludes barium oxide, which is classified under heading 2816.

Common Misclassification
The most common misclassification occurs with synthetic barium carbonate, which is classified under HS code 2836.60. Synthetic barium carbonate is a chemically manufactured product with higher purity levels than the natural mineral. Another common error is confusing it with barium oxide or hydroxide, which are classified under 2816.40. It is also sometimes confused with natural barium sulphate (2511.10).
FAQ
What is the HS code for natural barium carbonate?
The HS code for natural barium carbonate, also known as witherite, is 2511.20.
Can calcined witherite still be classified under 2511.20?
Yes, natural barium carbonate that has been calcined remains under HS code 2511.20, provided it has not been chemically processed into a synthetic compound.
