What is new in ADR 2027

DGAssistant supports ADR 2027 from 1 January 2027

From that day, the transport document, the 1.1.3.6 calculation, the checklist and the package marking prepared by DGAssistant follow the 2027 edition of ADR.

ADR 2027, the new edition of Annexes A and B of the Agreement concerning the International Carriage of Dangerous Goods by Road, enters into force on 1 January 2027, after no Contracting Party objected to the amendments. As usual, ADR 2025 may still be applied until 30 June 2027 (1.6.1.1). DGAssistant supports ADR 2027 from 1 January 2027. The changes affect the 1.1.3.6 exemption, several UN numbers, the marking of cargo transport units with installed batteries, waste, tanks, training and the construction of vehicles.

31 December 2027	Last day for the previous model of the instructions in writing
1 January 2030	New tanks can no longer be approved under both Chapter 6.7 and Chapter 6.8

The 1.1.3.6 exemption: one limit for transport category 1

Until now, note a of table 1.1.3.6.3 allowed up to 50 kg per transport unit for UN 0081, 0082, 0084, 0241, 0331, 0332, 0482, 1005 and 1017, counted with a factor of 20 in the calculation of 1.1.3.6.4. ADR 2027 deletes this note: these goods follow the general limit of transport category 1, 20 kg with a factor of 50. The previous note and factor may still be applied until 31 December 2030 (1.6.1.61), which gives time to adapt, for instance to the vehicle requirements for explosives.

An example: a transport unit carrying 30 kg of chlorine (UN 1017) in cylinders adds up 600 points under ADR 2025 and benefits from the exemption. Under ADR 2027 the same load adds up 1 500 points and exceeds the limit of 1 000. In addition, UN 3563 and UN 3564 join transport category 2 for Class 9.

New and amended entries

• UN 3561 and UN 3562 are added for corrosive chlorophenols, and UN 2020 and UN 2021 become chlorophenols, toxic, solid or liquid, n.o.s.
• UN 2348 butyl acrylates, stabilized and UN 2862 vanadium pentoxide receive packing group II entries in addition to their packing group III entries.
• A corrosive hazard is added to UN 1040, UN 1041 and UN 3300, a toxic hazard to UN 1727, and both to UN 2372, whose tank conditions change.
• UN 3536 is divided into three entries for batteries installed in cargo transport units: UN 3536 for lithium ion, UN 3563 for lithium metal and UN 3564 for sodium ion batteries.
• UN 2857 and UN 3358 also cover heating machines.
• UN 3553 disilane may no longer be carried in tanks.
• Hybrid batteries with lithium ion and sodium ion cells are classified according to special provision 410, and the procedure for samples of energetic substances is completed (2.1.4.3.2 and 2.1.4.3.3).

Batteries and vehicles carried as cargo

• Cargo transport units in which lithium or sodium ion batteries are installed (UN 3536, 3563 and 3564) must display on both sides orange-coloured plates with the hazard identification number and the UN number, as already required by rail (5.3.2.1.4).
• Packaged vehicles of UN 3556, 3557 and 3558 must be marked and labelled in accordance with Chapter 5.2 (special provision 666).
• When damaged or defective lithium or sodium ion batteries are packed under P911 or LP906, the consignor must give the loader and the carrier a description of the conditions under which the packaging may be used and carried, attached to the transport document (special provision 680).

Waste

• Drums and IBCs of more than 150 litres with small residues may be carried for disposal or recycling even when their period of use or their periodic inspection has expired, for certain substances of Classes 3, 4.1, 5.1, 6.1, 8 and 9 and under additional conditions (4.1.1.11.2).
• For waste carried in tanks, the quantity stated in the transport document may be estimated when it cannot be measured at the loading place; this now applies to every type of tank, still only for certain substances (5.4.1.1.3.2).

Pressure receptacles and tanks

• Pressure receptacles approved by the United States Department of Transportation and imported under 1.1.4.7.1 may be carried to a disposal facility under the same conditions as ADR pressure receptacles (1.1.4.7.3).
• The periodic inspection interval of LPG cylinders built to EN 14140 may be extended to 15 years with the agreement of the competent authority (P200).
• Salvage pressure receptacles are limited by a pressure-volume product instead of a maximum capacity; existing ones may be used without the new mark until 31 December 2030.
• Cooling devices count as service equipment of tanks, and tanks with electrical heating must meet new requirements for their circuits and switch boxes (6.8.2.2.12 and 6.8.2.2.13).
• Tanks constructed from 1 January 2030 may be approved under Chapter 6.7 or Chapter 6.8, but not both. Existing tanks with a double approval keep it until their first periodic inspection after 1 July 2031 (1.6.4.71).
• Extra-large tank-containers intended for liquefied, refrigerated liquefied or dissolved gases must bear an orange band around the shell (5.3.5).

• The training provisions and the obligation to keep training records also cover persons without an employer and the self-employed (1.3).

Vehicle construction

• Rear protection must meet UN Regulation No. 58 (9.7.6 and 9.8.5); vehicles first registered before 1 January 2029 that do not meet it may continue to be used.
• Automatic engine fire suppression systems must meet UN Regulation No. 181 (9.7.9.1).
• Electrical systems that power accessories from a battery installed in the bodywork must meet the new provisions of 9.7.10, which refer to UN Regulation No. 100; vehicles first registered before 1 January 2028 may continue to be used without them.

What to review before applying ADR 2027
