The document a forwarder asks for first
A rechargeable camping lantern carries a lithium pack, and a lithium pack is a cargo that freight rules treat as a class rather than as a commodity. The pack powers an LED or COB array through a driver, and the lantern's beam and runtime claims rest on that pack. Before a shipment is accepted for air freight or cleared through a port, the forwarder looks for the test summary that supports the pack, and the summary is where the pack's compliance is stated. When the summary is absent, incomplete or out of date, the shipment does not move at the planned time, and the delay is usually discovered at the warehouse rather than at the factory.
For a buyer, the practical rule is that the summary is requested in the first round of the quotation rather than in the shipping week. A supplier who holds a current summary answers immediately; a supplier who will produce one when the order is placed is telling the buyer something about how the pack was qualified.
Check one: the report type
The first check is what kind of document is being offered. A test summary is a condensed statement of results and is the document most forwarders expect. A full test report carries the method, the equipment, the sequence and the raw results, and it is longer and more detailed. A self-declaration is a statement from the pack maker and is the weakest of the three.
The distinction matters because the document type determines what a forwarder can verify. A summary names the tests and states that they passed. A full report names the tests, the equipment, the sequence and the measured values, and it is the document a laboratory can be asked to re-issue if a shipment is challenged.
Check two: the cell and pack level
The second check is whether the summary covers the cell or the pack. A pack is built from cells, and a summary performed at the cell level supports the cell and not necessarily the pack. A pack-level summary covers the assembled pack as it will ship, including the protection board, the leads and the outer casing, and it is the level a forwarder needs.
The reason is the fault conditions. A pack can pass a cell-level regime and still fail at the pack level, because the protection board, the interconnects and the casing introduce failure modes that the cell does not have. A pack-level summary is therefore the minimum for a shipment that will carry the assembled unit.
A buyer should ask for the pack-level summary specifically. A supplier who offers a cell-level summary and describes it as covering the pack is making a claim the document does not support. A supplier who offers both should be asked which one the shipment will be documented against.
The four checks on a test summary
| Check | What it should give | What it means if it is missing |
|---|---|---|
| Report type | Summary, full report or self-declaration | The forwarder cannot tell what is being offered |
| Level | Cell or pack level | A cell summary does not support the assembled pack |
| Coverage | The model, revision and sample identity | The summary may not describe the shipped unit |
| Validity | The period the summary remains current | An expired summary may not support the shipment |
| Tests stated | The tests performed and their results | The summary states compliance without showing it |
| Packing instruction | The rule the pack is documented under | The freight cannot be booked without it |
Ask for the six rows, not the summary alone. A supplier who can fill them has a current, pack-level, covered summary. A supplier who can only provide a cell document has not qualified the pack.
Check three: sample coverage
The same applies to the sample identity. A summary produced on a golden sample describes that sample; a summary produced on production units describes the batch. A buyer who changes the logo on the housing has not changed the pack and may not need a new summary, but a buyer who changes the pack has changed the product and needs one.
A buyer should ask the supplier to state which model, revision and sample the summary covers, and to confirm in writing whether a change to the product re-opens the document. This is the question that prevents a shipment from being held at the port because the document describes an earlier configuration.
Check four: the validity period
A buyer should also ask whether the summary supports the packing instruction the forwarder will apply. A summary that states the tests passed but does not state the packing instruction leaves the forwarder to determine it, which is a step that can be avoided by a supplier who knows the pack.
A test summary ≠ a safety certificate
A second boundary: a cell-level summary is not a pack-level summary. The two cover different products, and a cell summary does not support a shipment of the assembled pack. A buyer who accepts a cell document and describes it as covering the pack has accepted a claim the document does not make.
A third boundary: a current summary is not a permanent one. The document is tied to the regime in force when it was issued, and it can be superseded. This is the gap that IEC 62133 and EU battery law addresses from the electrical safety side, and the same discipline applies to disposing of lantern batteries safely at the end of the pack's life.
Five questions for the supplier
- What kind of document is offered: a test summary, a full report or a self-declaration, and is it current? The type and the currency are separate facts.
- Was the summary performed at the cell level or at the pack level, and does it cover the assembled unit as it will ship? Pack level is the minimum for a shipment.
- Which model, revision and sample identity does the summary cover, and does a change to the pack re-open it? Coverage is a claim, not a general statement.
- When was the summary issued, against which version of the regime, and when does it fall out of date? Currency is a dated property.
- Does the document state the packing instruction the forwarder will apply, and can it be sent with the quotation rather than in the shipping week? The document is the point of the exercise.
Next step
Request the pack-level summary with its coverage and validity period, file it with the order, and ask the supplier to notify the buyer when the regime changes.
