Import Tips
• Verify geological origin with certificates to confirm natural chalk composition (primarily CaCO3 >95%) and avoid reclassification as synthetic
• Declare as 'crude' only if unground; grinding disqualifies from this heading—common pitfall leading to audits
• Check for impurities; excessive silica may shift to HTS 2517 pebbles if resembling road ballast
