Transport rules apply before the sale
Lithium batteries are regulated as dangerous goods for transport. The UN 38.3 test summary is the evidence carriers and freight forwarders ask for, and a shipment without it can be refused before it reaches the customer. The test is design-specific, so a new cell or pack configuration can require a new test.
The transport file and the product-safety file are related but not identical. IEC 62133 addresses the battery's safe operation; UN 38.3 addresses transport. A carrier may ask for both.
The EU Battery Regulation adds a lifecycle layer
The EU Battery Regulation introduces labelling, collection, due-diligence and, for some categories, carbon-footprint and recycled-content requirements that phase in over several years. The obligations follow the battery and the producer, not only the device sale.
A product with a built-in battery can therefore need WEEE registration and battery producer registration in the same market. The two registers are separate, and the reporting volumes are separate as well.
Frequently asked questions
Can I ship a battery product without UN 38.3?
Most carriers require the UN 38.3 test summary for lithium batteries. Without it the shipment can be refused regardless of the product's safety record.
Is IEC 62133 mandatory?
It is the usual safety standard for portable lithium batteries and is required by many certification schemes and retailers, even where the law references it indirectly.
Does a built-in battery change the EPR registration?
Yes. Battery producer responsibility is separate from WEEE in most markets, so the product can create two registrations.
