A word of counsel

The most prevalent error on this tariff line is filing a bill of entry for HCFC-141b on the assumption that the ITC (HS) Restricted classification is equivalent to a conditional free entry — it is not. The prohibition under the ODS Rules, 2000 is the controlling instrument, and only a documented feedstock application lifts it; a consignment without pre-verified end-use documentation will be detained and is liable to confiscation and re-export rather than mere amendment. Separately, importers handling quantities of HCFC-141b that exceed specified thresholds must also hold a Public Liability Insurance policy per S.O. 227(E) dated 24-03-1992.

Frequently asked

Does HSN 2903 73 00 require BIS certification?

No, dichlorofluoroethanes are not subject to any BIS Quality Control Order. Import is governed by the ODS (Regulation and Control) Rules, 2000 — which prohibit import except for feedstock use — along with CIB&RC registration and permit requirements under the Insecticides Act, 1968 where the substance is scheduled, and DGFT policy conditions under Notification 26/2015-20.

What documentation is required at the bill of entry for a permitted feedstock import of HCFC-141b?

A feedstock end-use declaration satisfying ITC (HS) conditions 1 and 4 of Chapter 29, CIB&RC registration and import permit where the product is scheduled under the Insecticides Act, 1968, and the mandatory Chapter 29 additional qualifiers per CBIC Circular 23/2023-Cus paragraphs 4.1 and 4.2 must all be uploaded in e-Sanchit before out-of-charge.

When does the NDPS import-certificate requirement apply to this tariff line?

If the specific dichlorofluoroethane compound is listed in the schedule to the NDPS Act, an import certificate under Rule 53 of the NDPS Rules, 1985 is required; imports outside the medical and scientific purpose category are further governed by Appendix-I to the ITC (HS) Schedule per ITC (HS) policy condition 2 of Chapter 29.
