Compliance steps

1
Where Trimethoprim figures in the Schedule to the Insecticides Act, 1968, obtain registration and an import permit from the Secretariat of the Central Insecticides Board and Registration Committee before filing the bill of entry. Import is restricted to places notified under Rule 45 of the Insecticides Rules, 1971.

2
If the substance is imported for medical or scientific purposes under the NDPS regime, obtain an import certificate under Rule 53 of the NDPS Rules, 1985 as per Chapter VII-A of those Rules; imports outside that category are governed by Appendix-I to the ITC (HS) Schedule. Upload mandatory e-Sanchit documents: certificate of analysis (0010dc), batch release certificate (0030dc), label of consignment (0110dc), registration certificate for drugs (101dc1), and import licence for drugs (9111dc) before out-of-charge.

A word of counsel

The most common error on this tariff line is filing the bill of entry with drug-regime documents (registration certificate 101dc1, import licence 9111dc) while overlooking the CIB&RC insecticide registration and the Rule 45 port restriction, which is an independent and concurrent requirement. Arriving at an unnotified port with a valid drug import licence does not cure the Insecticides Rules violation; the consignment is liable to detention and the importer to separate enforcement under the Insecticides Act, 1968. Verify both the notified import points and the NDPS import certificate applicability before vessel departure.

Frequently asked

Does HSN 2933 59 20 require BIS certification?

No, Trimethoprim falls outside the BIS Quality Control Order regime. Import is governed by the Central Insecticides Board and Registration Committee under the Insecticides Act, 1968, with a concurrent NDPS overlay under Rule 53 of the NDPS Rules, 1985 and DGFT ITC (HS) policy condition 2 of Chapter 29.

Which e-Sanchit documents must be uploaded before out-of-charge for this tariff line?

The mandatory uploads are: certificate of analysis (0010dc), batch release certificate (0030dc), label of consignment (0110dc), registration certificate for drugs (101dc1), and import licence for drugs (9111dc); the proper officer verifies these before granting out-of-charge where the bill has not been routed through the PGA for NOC.

When does the NDPS import certificate requirement apply, and what governs imports outside the medical and scientific exemption?

The import certificate under Rule 53 of the NDPS Rules, 1985 is required for imports for medical and scientific purposes under Chapter VII-A of those Rules; all other imports of NDPS-scheduled substances under this CTI are governed by Appendix-I to the ITC (HS) Schedule per ITC (HS) policy condition 2 of Chapter 29.
