UN 38.3 Compliance Checklist

UN 38.3 is the transport test standard for lithium cells and batteries, and air, sea and road carriers ask for UN 38.3 evidence before they accept a lithium battery shipment. UN 38.3 evidence supports transport only; product safety certification is a separate evidence track. The T.1 to T.8 test sequence and how testing is scoped are covered on UN 38.3 Battery Transport Testing.

Who Needs UN 38.3 Evidence

UN 38.3 evidence is needed for lithium metal and lithium-ion cells and batteries shipped alone, packed with equipment, or contained in equipment. The parties that hold it or pass it on:

Cell manufacturers and battery pack manufacturers.
Original equipment manufacturers (OEMs) shipping products that contain lithium batteries.
Importers and distributors shipping lithium batteries across borders.
Third-party logistics (3PL) providers and fulfillment operations handling battery-containing products.

What the Test Summary Must Contain

Downstream shippers usually receive the UN 38.3 test summary, not the full test report. Check that each summary contains:

Identification of the cell or battery tested, with configuration details.
The tests performed, with results and references.
Manufacturer and test laboratory information.
Signature or authorization and issue date.

A test summary covers only the configuration that was tested. Evidence from a similar battery does not cover the shipped product, and results go stale after changes to the design, cell, battery management system (BMS) or supplier.

What UN 38.3 Does Not Replace

UN 38.3 does not replace product safety testing and certification. Most battery compliance programs keep separate evidence tracks for:

IEC product safety standards such as IEC 62133-2 and IEC 62619 (see IEC Battery Safety Standards).
Stationary storage system standards used in various markets.
Jurisdictional regulations on labeling, extended producer responsibility (EPR), battery passports and recycling (see Battery Regulations Overview).

Pre-Shipment Checklist

Shipping scenario defined: battery alone, packed with equipment, or contained in equipment.
Shipped configuration confirmed: cell type, capacity, BMS, enclosure, connectors.
UN 38.3 testing complete for that exact configuration or a defensible qualified family.
Current test summary issued to logistics partners, with access controlled.
Prototypes held until transport evidence is confirmed.
Change-control triggers in place that require re-test or engineering justification.
Shipping evidence packet kept per stock keeping unit (SKU) and route to market.
