A word of counsel

The most common error on this tariff line is assuming that textile-use enzymes fall outside the drug-documentation regime because the product is an industrial processing aid rather than a pharmaceutical. The e-Sanchit document set — Registration Certificate, Import Licence, Certificate of Analysis, Batch Release Certificate, and Label of Consignment — is applied at the CTI level regardless of declared end-use; consignments arriving without all five documents uploaded will be detained pending compliance, accumulating demurrage and ground rent at the port.

Frequently asked

Does HSN 3507 90 10 require BIS certification?

No, no BIS Quality Control Order covers industrial enzymes under this tariff line. Import is governed at the bill-of-entry stage by CBIC customs verification of drug-category documentation, including a Registration Certificate for Drugs (101DC1) and Import Licence for Drugs (9111DC), uploaded in e-Sanchit.

Are all five e-Sanchit documents required even for industrial textile-processing enzymes?

Yes. The CCR specifies all five document codes — 0010DC, 0030DC, 0110DC, 101DC1, and 9111DC — as mandatory for this CTI; the proper officer must confirm their presence before granting out-of-charge regardless of the declared industrial end-use.

What happens if the Import Licence for Drugs has expired at the time of filing the bill of entry?

An expired Import Licence for Drugs renders the mandatory document set incomplete; the consignment will be detained at port until a current licence is uploaded in e-Sanchit, with demurrage and ground rent accruing during the period of non-compliance.
