In customs declaration procedures, goods under different trade modes within the same shipment cannot be consolidated into a single filing. This regulatory requirement stems from varying supervision policies attached to distinct trade categories, necessitating separate processing.
A practical example illustrates this principle: When a single air waybill contains both complimentary spare parts provided by domestic suppliers and regular commercial goods requiring payment, customs clearance must follow bifurcated procedures. After cargo arrival and tally completion at port, the declaration documents should be divided based on quantity and weight measurements, creating two separate manifests.
The split filings would then proceed under corresponding trade classifications—"other import/export free of charge" for the donated components and "general trade" for the purchased merchandise. This methodological separation ensures both regulatory compliance and operational efficiency throughout the clearance process.
Failure to observe this protocol may result in processing delays or administrative penalties, customs authorities warn. The procedural distinction allows for proper application of tariff treatments, valuation methods, and documentation requirements specific to each trade type.
