A word of counsel

The most frequently overlooked obligation on this tariff line is the post-import CWC notification: importers who clear the consignment without following up within 30 days of import — notifying all five specified authorities and submitting the bill of entry copy to DGFT — are in breach of the Appendix II condition independently of whether the CIB&RC permit and NDPS certificate are in order. The CWC notification duty is a recurring, consignment-by-consignment obligation and cannot be discharged by a one-time declaration at the time of filing.

Frequently asked

Does HSN 2904 91 00 require BIS certification?

No, trichloronitromethane (chloropicrin) is not covered by any BIS Quality Control Order. Import is governed by the Central Insecticides Board and Registration Committee under the Insecticides Act, 1968, overlaid by CWC Category 1C chemical controls under ITC (HS) policy condition 3 of Chapter 29.

To which ports is the import of chloropicrin restricted?

Import is restricted to ports specified under Rule 45 of the Insecticides Rules, 1971; the current list should be confirmed with the CIB&RC secretariat before placing the purchase order, as arrival at an unspecified port triggers consignment detention.

Does the NDPS overlay apply to chloropicrin, and what does it require?

If the substance falls within the schedule to the NDPS Rules, 1985, an import certificate must be obtained under Rule 53 of those Rules before import; consignments outside that scheduled category remain subject only to the CIB&RC permit and the CWC post-import notification regime.
