Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If alloyed with other metals or chemically treated
Alloyed calcium or chemically modified forms are classified as prepared chemical mixtures outside pure elemental headings in Chapter 28.
If in phosphor bronze or copper phosphide form with >15% phosphorus
Chapter notes specify certain phosphides including copper phosphide fall under 2853, not pure calcium.
If manufactured into welding wire or rods
Calcium shaped into wire or rods for welding is classified as cored wire of base metals in Chapter 83, not elemental metal.

Import Tips & Compliance
• Verify purity exceeds 99% to confirm elemental classification; obtain safety data sheets for hazardous material handling during transport
• Ensure proper UN packaging for reactive metals to avoid pyrophoric risks
• Declare exact form (granules vs lumps) to prevent misclassification
