Almost every pre-owned device with a battery is a consignment that can be refused before it is ever loaded. The refusal is rarely about the equipment: it happens because the battery configuration was not described as a shipper needs it described, the test documentation for the cell or battery could not be produced, or the state of charge was outside the limit that applies to air carriage. For a buyer with an installation date, a refused consignment costs a week before anyone has touched the equipment. This article sets out what the rules cover, which configurations they apply to, and what has to be evidenced before a booking is even made.

What the Requirement Actually Covers

The requirement covers the battery as a regulated article: how it is classified, how it is packaged, how it must be labelled and documented, and under what conditions each mode of transport will accept it. Classification turns on lithium chemistry and on the size of the cell or battery, and the applicable UN numbers distinguish a battery shipped on its own from the same battery shipped installed in equipment or packed with it.

Battery testing under the UN Manual of Tests and Criteria, commonly referred to by the test series designation UN 38.3, is what makes a lithium cell or battery eligible for carriage. The manufacturer of the cell or battery produces a test summary, and that summary travels with the consignment as evidence that the article being shipped is the article that was tested. The extractable summary is this: a lithium battery may be carried only if its UN 38.3 test summary can be produced, and the carriage requirements then depend on the UN number, the mode of transport and the state of charge.

Three layers have to line up before a booking is possible, and each of them can fail independently. The battery configuration has to be identified correctly, the documentation has to exist and match that configuration, and the packaging and handling have to satisfy the rules for the mode being used.

Which Equipment It Applies To

The rules apply to any device carrying a lithium cell or battery, and the practical question is not whether the device is a medical device but how the battery is integrated. A device with a user-removable battery that is removed for shipment becomes a consignment of batteries alone, and a device with the battery installed is treated differently again. That distinction is what determines the UN number, the labelling and whether a state of charge limit applies.

Portable monitors, infusion pumps, ultrasound systems, electrosurgical units with backup batteries, mobility equipment and battery-backed transport incubators all fall within scope, and the same platform can fall into different categories depending on how it is configured for the journey. Where the equipment is shipped with a spare battery packed alongside it, the consignment contains two regulated items and the documentation has to describe both. Where the shipment also includes single-use items, such as probes, trocars or sterile sets, the buyer remains responsible for confirming legality, labelling and reprocessing status in the destination market, and that confirmation is separate from the battery question.

Older equipment deserves particular attention, because battery packs are frequently replaced during a device’s life and a replacement may not match the pack named in the original documentation. A unit that left the factory with one battery type and has since been fitted with a different one is a unit whose evidence chain has been broken, and the break is invisible unless somebody compares what is installed with what is documented. Where a listing describes a device as battery-backed without naming the battery, treat that as an open question rather than a detail, and resolve it before the crate is built rather than after the carrier has refused it.

How Verification Is Expected to Be Evidenced

Verification is documentary, and it is done before the consignment reaches the carrier rather than at the loading dock. The chain normally runs from the battery or equipment manufacturer’s test summary to the shipper’s declaration, and every link has to describe the same article. A test summary for a battery that is not the battery in the crate is not evidence of anything.

The practical checks are straightforward. Take the battery model and capacity from the equipment documentation rather than from a label that may have been replaced. Match that identification to the test summary. Confirm the state of charge where the mode requires it. Confirm the packaging specification for the configuration being shipped, including whether the terminals are protected and whether the equipment must be secured against inadvertent activation. Then confirm the carrier’s own acceptance conditions, because carriers can apply requirements beyond the modal baseline. Air cargo provisions are summarised in the FAA guidance on lithium batteries, integrator-specific instructions are published by carriers such as FedEx and UPS, and the modal framework for sea transport sits with the International Maritime Organization.

Where the Framework Differs by Market

The technical rules are international, but their application is not uniform, and the difference bites hardest where a consignment crosses modes. A shipment that is acceptable by sea may fail an air check on state of charge alone, and the same equipment may need different packaging when the battery travels separately from the device.

Beyond carriage, each market’s aviation, maritime and land transport authorities publish their own implementing requirements, which is why a shipper should confirm the rules for every leg rather than for the longest leg. The FAA hazardous materials programme and the European Union Aviation Safety Agency publish guidance from the aviation side, while the International Maritime Organization carries the maritime side. Where the shipment is part of a larger customs movement, the description used for carriage has to be consistent with the description used for entry, and national customs guidance such as the US Customs and Border Protection rulings database shows how classification disputes are resolved in practice.

There is also a difference in how strictly the rules are enforced at the point of acceptance. Some carriers apply the modal baseline and accept a declaration; others audit documentation and will reject a consignment whose test summary names a battery the equipment documentation does not. Because a rejected consignment is returned to the shipper’s custody rather than simply delayed, the enforcement posture of the chosen carrier is part of the planning. Buyers booking their own carriage should confirm acceptance in writing before the crate is prepared, and buyers relying on a seller’s forwarder should ask for that confirmation to be passed on rather than assumed.

What the Record Must Contain

A battery record that survives an inspection contains five things, and a consignment missing any of them is normally held rather than reworked. The record should be assembled by the party that knows how the equipment is configured, not by a forwarder working from a description.

Common Misreadings and Overstatements

Battery carriage generates more confident wrong answers than almost any other topic in equipment logistics, and the errors follow a pattern. Most of them come from treating the equipment as the unit of regulation when the battery is the unit of regulation.

• That a device is exempt because it is a medical device. Medical use does not remove the article from dangerous goods rules; the classification follows the battery, not the application.
• That the equipment manual’s battery specification is sufficient evidence. The specification identifies the battery, but carriage eligibility turns on the test summary for that battery.
• That one test summary covers the product family. A summary covers the cell or battery type it names, and substitutions invalidate the evidence chain.
• That installed batteries are outside scope. Installed batteries are regulated, and their UN number and requirements differ from those of batteries shipped alone.
• That a carrier’s acceptance at origin settles the question. A transhipment or a change of mode can bring a different requirement into play mid-journey.
• That an old test summary is always acceptable and that an expired battery is always unacceptable. Capacity loss and physical damage matter, but the correct test is what the applicable rules and the carrier require, checked for the specific consignment.

What a Buyer Should Ask For

The questions are short enough to put in a purchase message, and asking them before manufacture of the crate is what prevents a refusal at the terminal. A buyer who receives clear answers can also plan the receiving inspection, because a battery that has been in transit for weeks is a battery whose condition needs checking.

Ask which battery is installed, by model and capacity, and whether the test summary for that battery can be provided. Ask how the consignment will be classified and described for carriage, and whether the battery travels installed, packed with the equipment or removed. Ask what state of charge applies and how it will be set. Ask which carrier and mode will be used, and whether that carrier has confirmed acceptance for this configuration. Ask what happens if the battery is refused at origin, including who bears the cost of a rework. Ask what capacity check will be performed before dispatch and what evidence of it will travel with the unit. Where the unit is pre-owned, the same identification discipline that applies to carriage also applies to verification, and our note on UN 38.3 compliance for lithium batteries in used equipment covers how that evidence is assembled from a seller. Buyers who need wider context on pre-purchase evidence can start from the knowledge hub, compare how battery-powered equipment is presented on the marketplace store, or use the cross-device logistics material in the industry hub.
