For imports under the medical and scientific purpose special provision, ensure the certificate specifically references Chapter VII-A of the NDPS Rules, 1985.

A word of counsel

The most common error on this tariff line is conflating the NDPS import certificate regime with the drugs-registration and import-licence documentation stack: the Rule 53 import certificate governs NDPS-schedule compliance, while the Registration Certificate (101dc1) and Import Licence for Drugs (9111dc) are separate instruments issued under drugs law and must be uploaded independently in e-Sanchit. Arriving without both sets of clearances simultaneously causes consignment detention at the port of entry pending full documentary compliance.
