Customs amendments expand administrative powers and impose mandatory appeal pre-deposit requirements, altering tariff and exemption rules. Amendments expand customs officer designations, rename the settlement commission to include service tax, permit pre-filing of Bills of Entry for land imports, and prescribe mandatory fixed pre-deposit requirements for appeals subject to a statutory ceiling. The First Schedule and tariff notifications are adjusted to change basic customs duties and unit codes, safeguard duty is extended to inputs/raw materials of EOUs cleared into the domestic market, and sectoral duty and exemption changes are made across chemicals, energy, metals, electronics, textiles, renewable energy, capital goods, health and security imports, including immediate-effect provisions under provisional collection powers.
