1
Verify the exporting country is a State Party to the Chemical Weapons Convention before placing the purchase order. Import of Category 1B chemicals from non-State Parties is prohibited under Appendix II to Schedule I of the ITC (HS) Import Policy, and a consignment from a non-State Party will be refused clearance and is liable to seizure.

Within 30 days of each import, submit post-import notifications to the National Authority Chemical Weapons Convention (Cabinet Secretariat, Ministry of External Affairs, D&ISA), the Department of Chemicals and Petrochemicals, and DGFT — attaching a copy of the bill of entry to each DGFT submission. Where the import quantity exceeds the threshold for hazardous substances, take out a public liability insurance policy under the Public Liability Insurance 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 clearance at the bill-of-entry stage as full compliance and overlooking the mandatory post-import notification cycle. The 30-day window for notifying the National Authority Chemical Weapons Convention, the Department of Chemicals and Petrochemicals, and DGFT is a continuing obligation that attaches to every consignment independently; a missed or late submission constitutes a separate breach of the ITC (HS) policy condition, distinct from any customs penalty exposure under the Customs Act, 1962.
