Industrial Calcium Carbide Briquettes from China
Calcium carbide formed into dense briquettes for efficient storage and transport in steelmaking and carbide lamp applications. Falls under HTS 2849.10.00.00 as chemically defined calcium carbide, explicitly included in Chapter 28 despite physical forming. Briquettes reduce dust and improve handling safety.

Import Tips
• Document briquetting process doesn't add binders; pure pressed carbide stays in 2849.10
• Use IPPC permits for facilities generating acetylene from imported carbide
• Watch for reclassification if briquettes exceed 15% phosphorus (shifts to 2853 per note)
