HS Code for Calcium borate
Calcium borate is classified under HS code 2840.20 as a chemical compound. Heading 2840 covers borates and peroxoborates. While natural calcium borates (like colemanite) are classified in Chapter 25 as mineral products, the refined or chemically produced calcium borate falls under Chapter 28, which covers inorganic chemicals. Subheading 2840.20 is the residual category for "other" borates that are not disodium tetraborate (borax). The classification depends on the purity and the manufacturing process; if the product has been chemically treated to achieve a specific concentration or to remove impurities found in the natural ore, it is treated as a chemical product. This distinction is vital for customs purposes, as chemical products often face different regulatory requirements and tariff rates compared to raw minerals. Calcium borate is widely used in the glass and ceramic industries as a flux and in the production of fiberglass.

Common Misclassification
Calcium borate is frequently misclassified under 2528.00, which covers "natural borates and concentrates thereof." The key difference is the level of processing; if the material is simply crushed or washed ore, it belongs in Chapter 25. If it has been chemically precipitated or refined to a high degree of purity, it belongs in 2840.20. Another misclassification occurs with 2840.11 or 2840.19, which are reserved specifically for disodium tetraborate (borax). Importers must ensure the cation (calcium vs. sodium) is correctly identified before selecting the code.
