<h1>Courier clearance rules updated to add GSTIN and replace multiple courier bill and shipping bill forms with new standardized templates.</h1> The notification amends the Courier Imports and Exports (Clearance) Regulations, 1998 to add a definition of Goods and Services Tax Identification Number (GSTIN) and to substitute existing courier bill and shipping bill forms with designated 'new' forms (CBE-IV, CBE-V, CBE-IX, CBE-X, CSB-II, CSB-V, CBEx-II). The new templates standardise data fields including GSTIN, airway bills, invoices, assessable value (Section 14), tariff classification, IGST and GST Compensation Cess, and require agent declarations and signatures of authorised couriers and customs officers.
