Packaging is an integral part of many products that cannot be separated. The management, transportation, and packaging of exported dangerous goods in accordance with unified and standardized principles is of great significance for China to protect the safe transportation of exported dangerous goods and expand exports.
Dangerous goods must meet the corresponding packaging and transportation requirements, and logistics costs are higher compared to ordinary goods enterprises. However, for hazardous goods transported in small quantities, the United Nations Dangerous Transport Regulations and Chinese laws and regulations stipulate that if the quantity and packaging meet the relevant Limited quantities or Excepted quantities standards, many related transportation regulations can be exempted, providing great convenience for the transportation of such substances, and even to some extent equivalent to ordinary goods, comparable to a gold medal in amnesty.
The definition of "Limited Quantity" (LQ) is similar to "Exceptional Quantity" (EQ), which means that when dangerous goods are transferred for transportation, if the quantity is small and the packaging meets certain requirements, some technical requirements for the transportation of dangerous goods can be exempted (such as the carrier's qualification requirements).
What are the similarities and differences between "limited quantity" and "exceptional quantity"?
1、 Partial provisions on pardoning TDG
Similarities: Dangerous goods packaged in "limited quantity" and "exceptional quantity" may not be bound by other provisions except for certain provisions in the "Recommendations for the Transport of Dangerous Goods - Model Regulations" (TDG).
Differences: The TDG terms for "limited quantity" and "exceptional quantity" pardons are not the same. Compared to "exceptional quantity", "limited quantity" needs to comply with more TDG terms.
1. TDG terms to be followed for "limited quantity"
(a) Part 1, Chapters 1.1, 1.2, and 1.3:
(b) Part 2:
(c) Part 3, Chapters 3.1, 3.2, and 3.3;
(d) Part 4, paragraphs 4.1.1.1, 4.1.1.2, and 4.1.1.4 to 4.1.1.8:
Note: When air freight is used, supplementary regulations should also be applied; Refer to Chapter 4, Part 3 of the Technical Regulations for the Safe Transport of Dangerous Goods by Air of the International Civil Aviation Organization.
(e) Part 5:
（1） Air freight: Chapters 5.1, 5.2, and 5.4:
（2） Sea freight: Paragraphs 5.1.1.2, 5.1.2.3, 5.2.1.7, and Chapter 5.4:
（3） Road, railway, or inland waterway transportation: Sections 5.1.1.2, 5.1.2.3, 5.2.1.7, and 5.4.2.
(f) Manufacturing requirements in Section 6.1.4, 6.2.1.2, and 6.2.4 of Part 6;
(g) Part 7, Section 7.1.1, except for the first sentence of 7.1.1.7, paragraph 7.1.3.1.4, and subsection 7.1.3.2.
2. TDG terms to be followed for the number of exceptions
(a) Training requirements in Chapter 1.3:
(b)
Classification procedures and packaging category standards for Part 2:
(c) The packaging requirements in sections 4.1.1.1, 4.1.1.2, 4.1.1.4, 4.1.1.4.1, and 4.1.1.6.
2、 Using packaging types
Similarities: Dangerous goods packaged in "limited quantity" and "exceptional quantity" cannot be packaged in a single package, and must be packed in inner packaging.
Differences: Dangerous goods packaged in "limited quantities" should be placed in inner packaging with appropriate outer packaging. If fragile inner packaging is used, it should be placed in a sturdy intermediate packaging. Otherwise, intermediate packaging may not be suitable;
Dangerous goods packaged in "exceptional quantities" should be securely packed in intermediate packaging with cushioning materials to ensure that they are not damaged, penetrated, or leaked under normal transportation conditions.
3、 The packaging should have corresponding markings
Similarities: Dangerous goods packaged in "limited quantity" and "exceptional quantity" should have durable and easily recognizable corresponding markings on the outer packaging to indicate the use of "limited quantity" or "exceptional quantity" for the goods.
Differences: The "limited quantity" marking is different from the "exceptional quantity" marking. Air transport dangerous goods packages packaged in "limited quantity" have separate marking requirements, while dangerous goods packages packaged in "exceptional quantity" should display the main hazard category.
4、 Transport with "limited quantity" and "exceptional quantity" cannot exceed the upper limit
Similarity: To determine whether dangerous goods can be transported in "limited quantity" and "exceptional quantity", it is necessary to search for the "limited quantity" and "exceptional quantity" indicated in the TDG "List of Dangerous Goods" based on the United Nations Dangerous Goods Number (UN Number).
Differences: The total limit of dangerous goods transported in "limited quantity" and "exceptional quantity" is different. According to the "Measures for the Safety Management of Road Transport of Dangerous Goods", if the total weight (including packaging) of "limited quantity" dangerous goods carried by transport vehicles does not exceed 8000 kilograms, they can be transported as ordinary goods; If the number of dangerous goods packages carried by transportation vehicles does not exceed 1000, they can be transported as ordinary goods. Referring to the maximum net filling capacity of each outer packaging of "exception quantity", which does not exceed 1 kilogram (E1), the maximum limit for transporting "exception quantity" dangerous goods by transport vehicles is lower than the maximum limit for transporting "limited quantity" dangerous goods. This is also the reason why there are more clauses that are pardoned for transporting dangerous goods with "exception quantity".
