Compliance steps

1

2
Confirm that the consignment CIF value and product description align with the 8-digit classification for tripolite under Chapter 25, specifically the apparent specific gravity of 1 or less condition. Misclassification between 2512 00 10 (kieselguhr/diatomite) and 2512 00 20 (tripolite) may trigger a reassessment and re-examination at the port.

A word of counsel

The single most common error on this tariff line is treating the Phytosanitary Certificate as optional because tripolite is a mineral product rather than a plant-derived commodity. The e-Sanchit obligation under document code 851000 applies irrespective of this distinction, and consignments arriving without the uploaded certificate are detained pending regularisation, attracting demurrage and ground rent at the port of import.

Frequently asked

Does HSN 2512 00 20 require BIS certification?

No, tripolite and similar siliceous fossil meals are not covered by any BIS Quality Control Order. The operative requirement at the bill-of-entry stage is the submission of a Phytosanitary Certificate (document code 851000) uploaded in e-Sanchit before customs out-of-charge.

Is document code 851000 mandatory even when no plant-health risk is apparent in the consignment?

Yes. The CCR for this tariff line mandates the Phytosanitary Certificate upload in e-Sanchit as a condition precedent to out-of-charge, and the proper officer is required to verify it regardless of the apparent plant-health risk profile of the mineral.

What happens if the Phytosanitary Certificate is missing at the time of bill of entry?

The proper officer will withhold out-of-charge until the certificate is uploaded in e-Sanchit under document code 851000, during which time the consignment remains in customs custody and accumulates demurrage and ground rent charges at the port.
