A word of counsel

The dual-regime trap on this residual CTI is the most frequent cause of consignment detention: importers who correctly secure CIB&RC registration for a scheduled insecticide still face out-of-charge refusal when the Chapter 29 mandatory qualifiers required under CBIC Circular 23/2023-Cus are absent or incomplete in the import declaration. The qualifier requirement is chemical-identity specific and applies irrespective of the PGA track; a declaration filed without the stipulated para 4.1 and 4.2 qualifiers will be held pending amendment, accruing demurrage and ground rent.
