ADR/RID 2025 · Classification

The 11 new UN numbers introduced by ADR/RID 2025

ADR/RID 2025 introduced UN 0514 and UN 3551–3560. They cover both substances and articles, including batteries, vehicles and fire suppressant devices. A new UN number is a starting point for classification, not a complete set of transport instructions.

Eleven UN numbers: what they cover

The adopted additions to Table A include the eleven UN numbers below. The English amendment text in Croatia’s official gazette provides the complete new entries. Check the complete entry in the applicable Table A: the descriptions below are a reading aid, not ready-to-copy transport-document descriptions.

For road transport in Spain, consult ADR 2025 in BOE and its correction. For rail, use RID 2025 in BOE and OTIF’s current RID resources. The regulations share many classification provisions, but operational requirements remain mode-specific.

Similar names can lead to different entries

For batteries, distinguish the chemistry, whether the battery is shipped on its own or with equipment, and whether it powers a vehicle. The HSA summary explains the addition of sodium-ion provisions and the three vehicle entries. Review the goods’ actual condition and supporting information before selecting an entry.

UN 0514 and UN 3559 describe fire suppressant dispersing devices in different classes. Classification cannot be chosen merely for convenience. The Spanish correction explicitly assigns special provision 407 to UN 0514, correcting the initial publication’s reference to 347. Check that provision when assessing these devices.

For UN 3560, the concentration threshold matters, as do the full entry’s subsidiary hazard and packing requirements. Review any applicable transition separately; our ADR 2025 changes guide identifies 1.6.1.55.

Turn the entry into a shipment review

After identifying the appropriate entry, work through Table A and its referenced provisions. Confirm the full shipping description, classification code, subsidiary hazards, packing group where assigned, special provisions, permitted packaging or tank, marking, labels and transport documentation.

Keep the evidence that supports the selection. Depending on the goods, this may include the composition and safety data sheet, manufacturer information, battery test summary, device classification or packaging specifications. Check separate requirements for damaged goods, waste or connecting modes.

Send DGSA the product information, quantity, condition, packaging and proposed route to discuss the classification and transport checks for your Spanish operation in English.
