In the UN Recommendations on the Transport of Dangerous Goods (TDG), the InternationalMaritime TransportationInternational regulations such as the *International Maritime Dangerous Goods Code* (IMDG) impose relatively stringent technical requirements for the transportation of dangerous goods. However, for goods with smaller packaging specifications and lower hazard levels, are there any exemptions from certain packaging requirements to reduce transportation costs for exporting enterprises and facilitate smoother product exports? The answer is yes. This leads us to the topic we will explore next: "limited quantities" in the transportation of dangerous goods.

The term "limited quantity" refers to the situation where dangerous goods are transported in "limited quantity" packaging. Due to the smaller quantity and sufficiently sturdy packaging, the likelihood of hazards is relatively low. Even in the event of safety incidents such as leaks, the resulting impact is controllable. As a result, certain technical requirements for the transportation of dangerous goods can be exempted.

(1) Shippers may consign goods to carriers with dangerous goods transport licenses, general carriers (e.g., trucking or shipping companies), or even individuals.

(2) Dangerous goods transported in "limited quantities" must comply with basic packaging requirements when using packaging. These mainly include that the packaging must be of good quality, capable of withstanding the shocks and loads during transportation, and that the parts of the packaging in contact with the goods must be compatible with them.

The conditions for meeting the "limited quantity" transport requirements include: the UN number (hazardous materials transport number) of the dangerous goods is listed in the UN TDG as well as international maritime,Air TransportationPer TDG general requirements, additional packaging rules apply. For example, limited quantities shipments must use combination packaging (except for aerosols or small gas containers). Specific items like Division 1.4S explosives or Class 8 liquids have further packaging specifications.

According to the general requirements of the TDG regulations, the use of packaging must also comply with some additional rules. For example, when goods are transported in "limited quantities," they must be in the form of combination packaging (except for aerosols or small gas receptacles). Secondly, for specific hazardous materials, such as items in Division 1.4, Compatibility Group S, or Class 8 liquid goods, there are more detailed packaging requirements.

(1) When exporting dangerous goods transported in "limited quantities," it is not necessary to obtain the "Inspection Result of Performance for Transport Packaging of Export Goods" or the "Inspection Result of Use Appraisal for Transport Packaging of Export Dangerous Goods."

(2) For dangerous chemicals exempted from using dangerous goods packaging under international regulations, the Performance Test Result Sheet for Outbound Goods Transport Packaging is not required for export. However, for packaging used in imported dangerous chemicals, it must be inspected for compliance with the announcement requirements, and it is also necessary to check whether the product packaging has hazard communication labels.

Although the "limited quantity" transport can exempt certain packaging requirements, thereby reducing transportation costs and improving convenience to some extent, the safety responsibilities cannot be waived. Therefore, relevant units and individuals must continuously stay updated with the latest international regulations and remain vigilant during transportation to ensure the safety of people's lives and property.
