At its eleventh session, (9 December 2022), the Committee adopted a set of amendments to the Model Regulations on the Transport of Dangerous Goods (see ST/SG/AC.10/50/Add.1), concerning, inter alia:

- new UN numbers and provisions regulating the transport of sodium ion batteries, fire suppressant dispersing devices, disilane, gallium contained in articles and trifluoromethyltetrazole-sodium salt in acetone;
- a tightening of the conditions for the transport of tetramethylammonium hydroxide, including the creation of a new UN number for concentrations of not less than 25 %;
- changes to the provisions for the transport of battery powered vehicles, including the creation of three new UN numbers;
- an exemption for the transport of cells or batteries from production runs and pre-production prototypes;
- a new special provision to increase the authorized volume for transport in limited quantities of some compressed gases of Division 2.2 without subsidiary hazards;
- more specific concentration limits for ammonium nitrate hot concentrated solutions;
- exemptions for nitrocellulose membrane filters used in rapid test devices such as those for pregnancy tests, COVID-19 infections, or other infectious diseases;
- a clarification concerning pharmaceutical products (such as vaccines) that are packed in a form ready to be administered; and
- an update to the requirements for the use of recycled plastics in packagings;
