ADR Class Finder: practical guide

ADR class tells transport teams what type of danger they are handling: explosive, flammable, toxic, corrosive, radioactive, oxidizing or otherwise regulated. The class changes labels, documents and carrier options.

Use this finder as an orientation tool before preparing a shipment, then verify against the SDS, UN number and official dangerous-goods records.

Real examples

Practical notes

  • ADR class alone is not enough; UN number and packing group matter.
  • Some goods have special provisions or limited quantity rules.
  • Use trained dangerous-goods support for actual shipment release.

Common mistakes

  • Treating ADR class lookup as final approval.
  • Ignoring packing group, tunnel code and quantity limits.
  • Using old SDS data after a formulation change.
