  2. 2
    At the bill-of-entry stage, confirm that the Phytosanitary Certificate covers the specific consignment and quantity being imported. Customs proper officers are instructed to verify the 851000 upload on PGA-facilitated bills and withhold out-of-charge for non-compliant consignments.

A word of counsel

The most common error on this tariff line is treating kieselguhr as a purely industrial mineral and overlooking the Phytosanitary Certificate requirement. Because the raw material originates from sedimentary deposits that may carry soil-borne contaminants, customs proper officers are instructed to hold out-of-charge pending verification of document code 851000 in e-Sanchit — consignments arriving without a current, consignment-specific certificate face detention and demurrage until a compliant certificate is presented.
