Compliance steps

1
Determine the end-use of the substance before filing the bill of entry. Where the cyclic aldehyde polymer (including metaldehyde) is imported for insecticidal, rodenticidal, fungicidal, or herbicidal use, obtain a Certificate of Registration from the Central Insecticides Board and Registration Committee under Section 9 of the Insecticides Act, 1968. Where imported for a non-insecticidal purpose, obtain an import permit from the Registration Committee; import is restricted to the source specified on the certificate or permit, and only through ports notified under Rule 45 of the Insecticides Rules, 1971.
Section 9 of the Insecticides Act, 1968 · Rule 45 of the Insecticides Rules, 1971 · Policy condition 7 of Chapter 29 · CBIC Circular 35/2011 dated 09-08-2011 · CBIC Circular 7/2014 dated 07-03-2014
2
Where the substance falls within the medical devices listed in G.S.R. 102(E) dated 11-02-2020 issued by the Ministry of Health and Family Welfare, comply with all conditions specified therein including CDSCO registration before import. Upload the CDSCO registration document in e-Sanchit prior to bill of entry out-of-charge.

Comply with CBIC Circular 23/2023-Cus dated 30-09-2023 by declaring mandatory additional qualifiers in the import declaration for Chapter 29 commodities as stipulated in paragraphs 4.1 and 4.2, effective 15-10-2023. Where the substance is a hazardous substance imported in quantities exceeding specified thresholds, obtain a Public Liability Insurance policy under the PLI Act, 1991 per S.O. 227(E) dated 24-03-1992.

A word of counsel

The most common error on this tariff line is treating the DGFT 'Free' classification as a standalone clearance and overlooking the end-use-triggered PGA overlays: a consignment of metaldehyde declared as a general organic chemical but subsequently found to be used as an insecticide attracts retrospective CIB&RC registration enforcement, port seizure, and prosecution under the Insecticides Act, 1968. The source-of-import restriction on CIB&RC certificates and permits compounds the risk — a consignment shipped from a source not specified on the certificate is liable to confiscation even where the registration itself is current.

Frequently asked

Does HSN 2912 50 90 require BIS certification?

No, cyclic polymers of aldehydes are not covered by any BIS Quality Control Order. Import is governed by end-use-triggered PGA regimes — principally CIB&RC registration under the Insecticides Act, 1968 for insecticidal-use substances, and CDSCO registration under G.S.R. 102(E) dated 11-02-2020 for listed medical devices.

Does metaldehyde under this tariff line require both a CIB&RC certificate and compliance with DGFT policy condition 7 of Chapter 29?

Yes. Metaldehyde is a listed insecticide under Section 3(e) of the Schedule to the Insecticides Act, 1968 and is separately subject to policy condition 7 of Chapter 29; both the CIB&RC registration or import permit and compliance with the DGFT policy condition must be satisfied concurrently.

Do narcotic drugs or ozone-depleting substances under this heading attract additional restrictions?

Yes. Import of narcotic drugs and psychotropic substances under Chapter 29 is subject to policy conditions 2 and 3 of that chapter, and import of ozone-depleting substances is subject to policy conditions 1, 4 and 5 and the Ozone Depleting Substances (Regulation and Control) Rules, 2000.
