UN38.3: Test Summary vs Full Report for Shippers

What the term actually covers

Batteries carried by air are regulated as dangerous goods, and the evidence that a cell or pack has passed a transport test is usually presented in one of two forms: a summary, which is a concise statement of results, or a full report, which carries the underlying detail. Both exist for the same purpose, and both can be legitimate. Which one a shipment needs is not a product decision; it is a carrier and shipment decision, and it must be confirmed with the carrier before the cargo is booked.

For a heated scarf, the battery is a removable or packed power source inside a garment, and that raises two separate questions. The first is whether the battery itself is documented. The second is whether the garment, as packed, changes the shipping classification or the paperwork. Neither question can be answered from the spec sheet alone.

The garment is a layered product: an outer fabric, a lining at the skin side, stitched seams that carry the heating element, a finishing layer, and a battery pocket. When the battery is removed the cargo changes, but the garment still carries the element and the stitch route that powered it. The transport question and the garment question are therefore connected but separate.

The numbers behind the claim

Use the table below to compare the two document forms and to record what each shipment actually requires.

Document comparison table

Dimension	Test summary	Full test report	What to confirm before shipping
Length	Concise, results-focused	Detailed, with the underlying work	Which form the carrier requires for this shipment
Content	The pass results and the sample identity	The method, the samples and the results	Whether the sample identity matches the battery in the garment
Audience	Carriers and shippers	Labs, assessors and auditors	Which audience the document must satisfy
Version control	Dated, sometimes tied to a batch	Dated, tied to a specific sample	Whether the date covers the battery being shipped
Availability	Commonly supplied by the battery maker	Commonly held by the battery maker or the lab	Whether it can be produced for each shipment
Scope note	May cover a family of cells	Covers the specific sample tested	Whether the garment's pack is inside the scope

The habit that matters most is to record the answer per shipment. A carrier may ask for a summary, another may ask for a report, and the same carrier may change its requirement after a regulatory update. Do not treat last quarter's answer as this quarter's answer.

A test summary ≠ a full test report

The boundary to state plainly is that the shorter document is not a lesser version of the longer one; it is a different document with a different purpose.

A test summary is a concise statement of results, usually issued to be handed to a carrier or included in the shipping paperwork. It is designed to be read quickly by someone who needs the outcome, not the method. A full test report carries the method, the sample description, the measurements and the reasoning, and it is designed to be reviewed by an assessor or an auditor who wants to reconstruct what was done. Receiving a summary when a report was expected, or a report when a summary would have satisfied the carrier, is a paperwork mismatch rather than a product failure.

The risk for a heated scarf is that the battery inside the garment may not be the exact cell covered by the summary. A battery maker may issue a summary for a family of cells, and the garment may use a pack built around a cell from that family. That is a normal arrangement, but it only works if the pack and the cell identity are stated on the document. Ask the battery maker which battery the summary covers and whether your pack falls inside it, then ask the carrier what it needs for this shipment.

Questions to ask a supplier

Which battery model is the summary or report issued for, and does it cover the pack inside the garment?

Ask for the battery model reference and the pack description, and compare them with the document. A mismatch means the document does not describe the product.

Is the document dated, and does the date cover the battery being shipped?

Ask for the date on the document and the production date of the battery. A stale document is a mismatch even if the results are favourable.

Can you supply the summary, the full report, or both?

Ask which forms are available and how long each takes to produce. A supplier who can only produce one form is a supplier with a gap in the shipping workflow.

What will the carrier require for this shipment?

Ask the carrier directly, per shipment, and record the answer with the shipment reference. This is not a question for the supplier to guess at.

What changes trigger a refresh of the transport evidence?

Ask which change of cell, pack or garment construction forces a new document, and who owns it.

Common mistakes buyers make

Treating a test summary as though it were a full report.
Shipping with a document whose battery model does not match the pack inside the garment.
Reusing last quarter's carrier answer for this shipment.
Accepting a document with no date or no sample identity.
Skipping the carrier confirmation and relying on the supplier's summary of what is needed.

Each mistake is caught by naming the battery model, the document form and the carrier confirmation on the relevant line.

Frequently asked questions

Is one document always enough?

Not necessarily. Some shipments need a summary, some need a report, and the requirement is set by the carrier for that shipment. Confirm it before booking, and record the answer.

Can a summary cover a family of batteries?

It can, but only if the pack and cell identity are stated and the garment's battery falls inside the stated family. Ask the battery maker to confirm the scope in writing.

Who confirms what the carrier requires?

The carrier or the freight forwarder, per shipment. A supplier can tell you which document exists; the carrier tells you which document this shipment needs.

Next step

Confirm the document form with the carrier for each shipment, and check the battery model on the document against the pack inside the garment. For a shipment plan that states the transport evidence your route requires, request one through contact.
