Merchanting trade compliance: revised rules require single bank routing, documentary verification, and strict KYC/AML oversight. Revised MTT guidelines require that goods must not enter the Domestic Tariff Area, permit limited transformation with documentary proof, require compliance with export/import rules for each leg, and mandate that the entire MTT be routed through a single AD bank which must verify documents, ensure KYC/AML compliance, and maintain retrievable records for inspection.
