> Proof obligation requires importers, forwarders, and shippers to produce supporting evidence on demand – certificates of origin, declarations of conformity, weighing records, quality certificates, or damage photographs – to substantiate a claim or demonstrate regulatory compliance to authorities or business partners.

Proof obligation requires importers, forwarders, and shippers to produce supporting evidence on demand – certificates of origin, declarations of conformity, weighing records, quality certificates, or damage photographs – to substantiate a claim or demonstrate regulatory compliance to authorities or business partners. In customs procedures, it becomes particularly relevant when preferential tariff treatment is claimed, since the originating status of goods must be actively proved. In freight claims, proof obligation determines who bears the loss: a party unable to document a defect typically forfeits its right to compensation. Proof obligation should be distinguished from document obligation, which concerns the structured retention of records; proof obligation specifically refers to the active production of evidence to establish a material fact.
