A word of counsel

The most common error on this residual tariff line is treating the free-import status notified under DGFT Notification 44/2025-26 as a clearance to import without reference to end-use-triggered PGA regimes. Free import status under DGFT addresses only the ITC (HS) policy condition; it does not displace CDSCO registration, CIB&RC registration or the CIB&RC source-restriction, NDPS policy conditions, or the MEFCC insurance obligation. Failure to identify the correct PGA overlay at the bill-of-entry stage results in consignment detention pending mandatory registration documentation that cannot be obtained retrospectively.

Frequently asked

Does HSN 2933 49 90 require BIS certification?

No, this residual heterocyclic-compound tariff line is not covered by any BIS Quality Control Order. Import is governed by CDSCO under G.S.R. 102(E) dated 11-02-2020 for notified medical devices, CIB&RC under Section 9 of the Insecticides Act, 1968 for insecticidal substances, and NDPS policy conditions 2 and 3 where narcotics or psychotropic substances are involved.

Does the free-import status under DGFT Notification 44/2025-26 remove the CIB&RC source restriction?

No. DGFT free-import status governs the ITC (HS) policy condition only; the CIB&RC certificate of registration or permit specifies the permitted import source, and import from any other source is prohibited under Section 9 of the Insecticides Act, 1968 and Rule 45 of the Insecticides Rules, 1971.

When do NDPS policy conditions 2 and 3 apply to imports under this HSN?

Policy conditions 2 and 3 apply when the specific compound falls within the list of narcotic drugs or psychotropic substances covered under Chapter 29 of the ITC (HS) Schedule; importers should verify the scheduled status of the substance against the NDPS Act schedules before filing the bill of entry.
