Calcium Borate Precipitate from China
Calcium borate precipitate is a fine particulate form of calcium borate used in specialty ceramics and as a boron supplement. It is an 'other borate' because it is a metal borate other than sodium borate, and it is not excluded by Chapter 31 notes.

Import Tips
• Confirm the product is not a calcium cyanamide or other Chapter 31 fertilizer, as that would change classification
• Provide particle size distribution data to support the precipitate form
• Ensure the product is not mixed with organic binders that could alter classification
