Unworked or simply prepared chanks (mollusc shells)

WCCB CLEARANCE

HSN 0508 00 20 (Chanks) is subject to Wildlife Crime Control Bureau (WCCB) CITES permit controls under the Wildlife Protection Act, 1972, as chanks fall within the CITES-regulated specimen regime. The tariff line is also subject to ITC (HS) policy condition 3 of Chapter 05 administered by the Directorate General of Foreign Trade (DGFT), and a Health Certificate is required as a concurrent customs overlay.

Compliance steps
  1. 1
    Obtain a valid CITES certificate (document code 626000) for the chank consignment before shipment. Upload the certificate in e-Sanchit prior to filing the bill of entry; the proper officer will verify this upload before granting out-of-charge under the WCCB-facilitated clearance pathway.

  2. 2
    Upload the Health Certificate (document code 6360AQ) in e-Sanchit alongside the CITES certificate before out-of-charge. Both documents are mandatory at the bill-of-entry stage and non-upload results in consignment detention pending PGA verification.

A word of counsel

The most common error on this tariff line is treating the CITES certificate as the only mandatory document and omitting the Health Certificate (6360AQ) from the e-Sanchit upload. Both documents are independently verified at out-of-charge; a consignment carrying a current CITES certificate but lacking the Health Certificate will be detained, accruing demurrage and ground rent until the deficiency is rectified or the consignment is re-exported.

Frequently asked
Does HSN 0508 00 20 require BIS certification?
No, unworked or simply prepared chanks are not covered by any BIS Quality Control Order. Import is governed by the Wildlife Crime Control Bureau under the CITES permit regime and the ITC (HS) policy condition 3 of Chapter 05 administered by the Directorate General of Foreign Trade.
Which document codes must be uploaded in e-Sanchit for chanks at the bill of entry?
Two documents are mandatory: the CITES certificate (document code 626000) and the Health Certificate (document code 6360AQ); both must be uploaded in e-Sanchit before the proper officer grants out-of-charge.
What is the effect of ITC (HS) policy condition 3 of Chapter 05 on this tariff line?
Policy condition 3 of Chapter 05 of the ITC (HS) Import Policy restricts the import of chanks, making the CITES-based WCCB clearance a prerequisite and subjecting any non-compliant consignment to Restricted-import enforcement by DGFT.
