Meaning
Administrative liability represents the mathematical foundation for calculating air freight costs, defined by the greater of actual gross mass or volumetric mass. Statutory guidance from the Civil Aviation Administration of China requires this metric to govern all international outbound shipments. It functions as the legal basis for billing when cargo volume occupies disproportionate space relative to weight.
Customs authorities utilize this figure to verify duty declarations during port exit inspections.
Calculation Protocol
Official guidelines mandate that volume is derived by multiplying height, width, and length in centimeters, then dividing the result by a constant factor of 6000. Entities must standardize these measurements before submitting manifests to the carrier or the terminal operator. Any discrepancy between declared dimensions and physical inspection results subjects the exporter to revised billing and potential administrative penalties for misreporting.
Compliance Limit
Regulatory oversight restricts individual flexibility regarding dimensional reporting through strictly defined measurement methods that exclude protective packaging or non-affixed attachments. Enforcement practice relies upon certified scale readings taken at the point of origin, where inspectors compare physical weight against the invoice data. Disagreements between the carrier and the shipper regarding final figures undergo arbitration based upon the original airway bill documentation provided during the customs filing process.
Audit Mechanism
Verification involves cross-referencing shipping manifests with actual terminal weight reports to confirm the accuracy of total tariff payments. Authorities issue citations if the recorded data fails to align with the physical capacity of the cargo load. The final settlement of accounts necessitates adherence to the higher of the two values, regardless of whether the physical density of the goods justifies the price assessment.
