Inbound Receiving Inspection and Hazardous Cargo Documentation Audit Procedures
Inbound cell inspection requires dual-path verification of UN 38.3 documentation and AQL sampling of open-circuit voltage, impedance, and K-value drop.
Test Summary Document
Meaning
Regulatory records certifying that a specific lithium battery design has successfully passed the mandatory safety tests must be made available to the supply chain. Sourcing and compliance teams require a test summary document to verify that the cells they are purchasing are legally compliant for transport. This document is a standardized summary of the results of the United Nations testing and must be provided by the manufacturer or distributor.
The application of this requirement applies to all lithium ion and lithium metal cells and batteries.
Compliance Rules
International transport regulations mandate that this summary be made available to anyone in the supply chain, including freight forwarders and customs agents. The document must contain specific information, including the name of the cell manufacturer, the test laboratory, and the date the test report was issued. It must also list the physical and electrical parameters of the cell, such as its mass and watt-hour rating.
Sourcing professionals must verify that the document matches the cells being shipped to avoid customs delays.
Information Disclosure
Transparency is improved by this requirement because it allows logistics providers to verify compliance without accessing the proprietary details of the full test report. The document can be provided electronically and must be signed by an authorized representative of the company. Sourcing teams should establish a central repository for these documents to ensure they are easily accessible during audits.
Sourcing Logistics
Sourcing contracts should include clauses that require the cell manufacturer to provide an updated summary if the cell design changes. This ensures that the buyer is always compliant with the latest transport regulations. Failure to provide a valid document can result in shipment rejection by air and ocean carriers, which can disrupt the production schedule of the pack assembly line.
