Battery, Liquid and Magnet Cargo: What Makes a Lane Capable

Capability Is a Document Set, Not a Route Attribute

Sellers ask whether a lane “takes batteries”, “takes liquids” or “takes magnets” as if those were features on a pricing sheet, sitting between the transit estimate and the weight bracket. They are not. A hazardous-goods-capable line is a stack of paper that has to line up before a carton reaches a terminal: a classification matching the article, a packing instruction matching the classification, an operator accepting that instruction on the aircraft actually used, an exporting authority that permits it, and a destination that will clear it. Remove one sheet and the shipment does not become slower — it becomes refused, at the worst moment in your calendar.

The useful question is therefore not does your line carry this, but which documents does this combination require, and who produces them. That reframing turns a promise into a checklist, and a checklist can be tested before money moves.

The Rulebook Moves Every Year, and the Quote Does Not

Air movement of dangerous goods follows the IATA Dangerous Goods Regulations, an annual edition that exists to implement the ICAO Technical Instructions for the current two-year cycle. The 67th edition came into force on 1 January 2026, aligned to the 2025–2026 ICAO Technical Instructions. Editions supersede; they do not grandfather.

In practice this means a lane that was correct for your product in November can be incorrect for the identical product in February, with nothing about the goods, the packaging or the aircraft having changed. Rate cards rarely announce it, because a rate card is marketing and the rulebook is compliance. Two habits cover you:

• Date every answer. When an operator tells you a lane handles an item, ask which edition of the regulations that statement is true under, and whether anything changed at the last 1 January.
• Re-test after each new year. A lane you have used for two peaks is not automatically valid for the third. The check costs one email; the failure costs the consignment.

Magnetic Material: UN2807 and the 2026 Description Change

Magnets travel as Class 9, UN2807, Magnetized Material — the family covering magnetic components, speakers and anything whose field is strong enough to matter to an instrument. The paperwork expectation was long simple: the goods-description field of the air waybill named the UN number, the proper shipping name, the class and the packing instruction.

For the 2026 cycle the association published a relaxation for this entry alone, permitting the waybill description to omit the UN number in defined circumstances. Read it carefully, because it is the kind of change that gets relayed as “magnets are no longer dangerous goods”. They are. What moved was a presentation field, for one entry, under one edition.

Three consequences follow. An operator who says “magnets don’t need a UN number anymore” without naming the edition and the condition is repeating something half-remembered. A relaxation on the waybill is not a relaxation on the package: marking, labelling and the shipper’s declaration keep their own rules. And magnets moving by sea or road fall under the IMDG Code or ground rules instead, so a multi-modal lane means asking the magnet question twice, in two vocabularies.

Aerosols and Perfumery: The Limit Is a Packing Instruction

“Liquid” is not a category in the regulations. Sprayed and perfumed products sit in different families with different mechanics, and the ceiling on a shipment lives inside the packing instruction rather than the product name.

Emphasise that third row, because most avoidable cost here is created there. A liquid is not a dangerous good for being liquid; regulation is a property of the substance, established from its formulation and datasheet. If a rate for your item carries a dangerous-goods surcharge, ask which UN number it charges for.

Where Carriers Add Their Own Prohibitions

The regulations set the ceiling of what may be flown when everything is done correctly. Each operator may then be stricter, and most are. The Dangerous Goods Regulations carry an operator-differences section listing states and airlines that deviate, and the 2026 edition includes national variations for France, the United Kingdom and Thailand — three places a China-to-Europe or China-to-Southeast-Asia consignee expects to reach without ceremony.

Common operator-level refusals to expect rather than discover: dangerous goods presented through the airmail stream instead of the express stream; whole classes unless they fall inside a narrow exception; packages in salvage or damaged packaging; and, on some flows, packing instructions the airline simply does not carry even though the rulebook permits them.

The commercial consequence is geometric. If a lane’s only path to your destination passes through a state whose authority restricts the class you ship, that lane does not exist for your product however confidently its name appears on a rate card. So ask which countries the routing touches before it reaches yours, and which 2026 operator differences apply in each of them.

What a Lane Operator Should Be Able to Show You

A line that genuinely carries these goods can produce evidence rather than assurances. The list is short, and any operator who bristles at it is telling you something:

1. A named acceptance rule for your item on that specific flight, under the current edition — not a general statement that they handle dangerous goods.
2. The packing instruction the shipment will be built to, and the per-package limits following from it.
3. Who prepares and checks the paperwork, and when in the week, since a declaration reviewed after the truck has left is not a control.
4. The rejection path: what happens to a package that fails terminal inspection, who is told, and how many days of your lead time that consumes.
5. Confirmation the same treatment applies at the transfer point, if the lane changes modes or carriers mid-journey.

The Questions That Decide Whether Your Goods Can Go on Monday

Compress the category into five questions you can put in writing today: what UN number and packing group this product carries as classified from its datasheet; which edition of the regulations that answer is based on; whether your operator accepts that class and instruction on the aircraft the lane actually uses; which transit states restrict it under current national differences; and who signs the declaration.

On our side we answer those five in writing, and the filing is not left to somebody else to chase. Special-category freight — loose batteries, DG containers, oversized furniture, automotive components, photovoltaic and storage gear, shopfitting materials — is a line we operate, and the honest description of it is that the document set is the service: we classify from the datasheet, draw up the declaration on the shipper’s own written authority, commission the per-mode assessment wherever the article needs one, and submit the assembled file as the named agent. Send the product, its datasheet, the packaging and the destination; we return the classification path, the limits and the name of the desk holding each paper, and only then a routing.
