2 – Limitations
2.3 – Dangerous Goods Carried by Passengers or Crew
With regard to mobility aids (battery-powered), the provisions have been revised to identify that removal of batteries is only necessary when the mobility aid design does not offer sufficient protection against potential battery damage. (Notably, when the mobility aids contain spillable batteries, the requirements for handling, loading, stowing upright, or removing the battery remain unchanged.)

A revision has been made clarifying that a dangerous goods package with excepted quantities can also include goods that are not covered under the Regulations.

A revision is made in the list (2.8.1) and the List of State Variations to include new states in addition to amended variations for existing states.
3 – Classification
The following revisions have been made:
- The provisions for classification of organic peroxides and self-reactive substances are revised to align completely with the wordings included in the UN Model Regulations.
- It is clarified that mixtures or substances that are classified as corrosive should be earmarked to Packing Group I when the test results don’t suggest a different packing group.
- Revision is made to lithium battery test summary requirements – test summary is no longer required for the button cells included in the equipment.

4.2 – List of Dangerous Goods
Changes to the dangerous goods list include:
- Per package maximum net quantity on cargo aircraft has been changed for wet batteries with acid (UN 2794), wet batteries with alkali (UN 2795), and cells with sodium (UN 3292) from “Unlimited” to 400 kg. UN specification packages should be used to pack these articles (the limit for which is 400 kg).
- Special Provision A154 has been added to the entries for battery-powered vehicles (UN 3171), engines and machinery (UN 3528, 3529, and 3530), life-saving appliances (UN 3072), and vehicles (UN 3166).

4.4 – Special Provisions
Changes made to the existing special provisions are as follows:
- With regarding special provisions A1/A2, a sentence has been added to specify that when an approval is made for dangerous goods, the authorization column in the Shipping Declaration should mention A1 or A2 as may be applicable.

New special provisions are as follows:
- A221 – assigned to compressed air (UN 1002) identifying that oxygen and nitrogen mixtures in specified concentrations may be shipped as UN 1002 without a requirement for a subsidiary hazard label Division 5.1.
- A223 – assigned to self-inflating life-saving appliance (UN 2990) and non-self-inflating life-saving appliance (UN 3072), identifying that these devices may be shipped as “non-restricted” cargo.
- A224 – assigned to articles consisting of miscellaneous dangerous goods (UN3548) identifying that the items with environmentally hazardous elements can be transported as cargo on a cargo or passenger aircraft as per the Packing Instruction 975 provision. Moreover, special provision A2 will not apply in this case.
- A225 – assigned to articles consisting of non-toxic, non-flammable gas (UN 3538) identifying that the items with a Division 2.2 gas without any subsidiary hazard can be transported as cargo on a cargo or passenger aircraft as per the Packing Instructions 222 provisions.
