UN 38.3 Lithium Battery Testing and Transport Documentation Support

UN Manual of Tests and Criteria subsection 38.3 testing, type-variation assessment and test-summary support for lithium metal and lithium-ion cells, batteries and equipment. This service is not the same as complete transport classification.

Service overview

Before transport, lithium cell and battery types generally need evidence that they meet Part III, subsection 38.3 of the UN Manual of Tests and Criteria. The test series includes altitude simulation, thermal, vibration, shock, external short circuit, impact/crush, overcharge and forced discharge as applicable to the sample type. SCS Testing supports type identification, testing and test-summary information while keeping packaging, state of charge, mode-specific transport and dangerous-goods declarations separate from UN 38.3 testing.

Applicable products or businesses

• Lithium-ion and lithium-metal cells, battery packs, power banks and energy-storage batteries
• Lithium batteries contained in or packed with equipment
• New types, changed designs or projects reviewing existing test coverage

Target market

• International air, sea, road or rail dangerous-goods supply chains, subject to mode-specific rules

Regulatory authority

• UN dangerous-goods transport framework
• Mode-specific authorities, rules and carrier requirements, assessed separately

Regulations, directives and standards

• UN Manual of Tests and Criteria, Part III, subsection 38.3
• Lithium-battery classification and transport conditions in the UN Model Regulations
• Mode-specific packaging, marks, documents and state-of-charge requirements

Service scope

• Cell/battery type, chemistry and model-family assessment
• Coordination of applicable T.1 to T.8 testing
• Test report and subsection 38.3 test-summary information
• Initial review of whether design changes affect prior test representativeness

Service process

• Collect cell/battery construction, capacity, mass and model relationships
• Determine sample category, applicable tests and preconditioning
• Prepare the required number and state of samples
• Complete testing and investigate anomalies or failures
• Issue the report and test-summary information and identify separate transport-document duties

Information required

• Cell and battery specifications, construction drawings and protection-circuit description
• Rated capacity, watt-hours, lithium content, mass and model list
• Critical components, BMS and cell-supplier information
• Charge/discharge method, sample state and safe-operating instructions
• Existing UN 38.3 reports and design-change records

Sample requirements

• Sample quantity, cycle state and preconditioning follow the Manual and the cell/battery category
• Production-representative batteries and any required cells must be supplied
• Testing can be destructive; tested samples should not be returned to normal product use

## Reports, certificates or registration outcomes Outputs include a UN 38.3 report for the agreed type and test-summary information for the supply chain. They are not automatically equivalent to an air/sea transport assessment and do not replace packaging, marking, declaration, state-of-charge or carrier requirements.

Factors affecting timing

The prescribed sequence includes preconditioning and multiple tests. Timing depends on sample category, cycle state, sample quantity, anomaly investigation and document completeness.

Common compliance risks

• Treating a UN 38.3 report as the complete dangerous-goods transport file
• Failing to assess the impact of cell, BMS, model or construction changes
• Test-summary information lacks model, laboratory or report identifiers
• The tested configuration differs from production

Is UN 38.3 a certification?

It is more accurately a type-testing and evidence requirement under the UN Manual, not a market certification issued by one authority.

## Does a UN 38.3 report alone permit air transport?

No. Mode-specific packaging, state-of-charge, marking, documentation and carrier requirements also apply.

## Can a report remain valid after changing the cell?

Changes to the cell, capacity, construction, protection circuit and type definition must be assessed.
