A word of counsel

The most common error on this tariff line is assuming that the CIB&RC schedule-check can be deferred to the port stage. Customs officers verify at the bill of entry whether a CIB&RC registration and permit are present; a consignment arriving without them at a non-notified port faces simultaneous detention under the Insecticides Rules, 1971 and Restricted-import enforcement under the ITC (HS) policy — demurrage and ground rent accumulate while the dual-PGA deficiency is resolved, with no guarantee of release short of re-export.

Frequently asked

Does HSN 2903 77 32 require BIS certification?

No, dichlorohexafluoropropane is not covered by any BIS Quality Control Order. Import is governed by CIB&RC registration and permit requirements under the Insecticides Act, 1968, with an NDPS Rules overlay and the ITC (HS) Restricted-import policy condition administered by DGFT.

Are all imports of dichlorohexafluoropropane subject to CIB&RC requirements, or only certain uses?

CIB&RC registration and permit apply only when the substance figures in the schedule to the Insecticides Act, 1968; the importer must verify schedule inclusion before shipment, as non-pesticide applications may fall outside the Insecticides Act but remain subject to DGFT Restricted-import controls and CBIC Chapter 29 qualifiers.

What happens if dichlorohexafluoropropane is also classified as an NDPS substance?

Imports for medical or scientific purposes require an import certificate under Rule 53 of the NDPS Rules, 1985 (details at cbn.nic.in); all other imports are governed by Appendix-I to the ITC (HS) Schedule under ITC (HS) policy condition 2 of Chapter 29, and non-compliance constitutes a Restricted-import violation with potential seizure and criminal liability.
