The notification amends earlier notification 45/2025 dated 24th October 2025, and makes extensive changes across multiple tables by omitting numerous exemption entries, extending the validity of several existing exemptions up to 31 March 2028, and inserting new entries granting nil basic customs duty on specified goods. The key additions include exemptions for monazite, rare earth compounds, sodium antimonate for solar glass, critical minerals, nuclear power equipment, aircraft and defence-related imports, renewable energy components, and inputs for solar photovoltaic manufacturing. Lists relating to life-saving drugs, rare diseases, and nuclear power projects have been expanded.
