A word of counsel

The most common error on this tariff line is treating diatomite as an inorganic mineral commodity exempt from plant-quarantine requirements and arriving at port without a Phytosanitary Certificate. Because the certificate must be issued by the exporting country's authority before departure, a missing document cannot be remedied post-arrival without detaining the consignment — detention, demurrage, and ground rent accumulate while the importer pursues a retrospective certificate that most exporting authorities will not issue.

Frequently asked

Does HSN 2512 00 30 require BIS certification?

No, diatomite and similar siliceous fossil meals are not covered by any BIS Quality Control Order. The operative import requirement is a Phytosanitary Certificate (document code 851000) to be uploaded in e-Sanchit before customs out-of-charge.

Who issues the Phytosanitary Certificate required for this tariff line?

The Phytosanitary Certificate must be issued by the competent plant-protection or national plant-protection authority of the exporting country and uploaded in e-Sanchit under document code 851000 before the bill of entry is processed.

What happens if the Phytosanitary Certificate is missing at the port of import?

The customs proper officer will withhold out-of-charge clearance until the mandatory document is verified in e-Sanchit, resulting in consignment detention, demurrage, and ground rent accruing at the port.
