Limited Quantity Hazmat


Limited Quantity dg

 In hazmat shipping, shippers may select shipping dangerous goods by using the term known as limited quantity hazmat. In dangerous goods regulations, this term means shipping hazmat in small quantities.

In other meaning, the shipper can ship certain dangerous goods which do not exceed certain quantity limits per inner packaging and outer packaging.


What is a limited quantity Hazmat?

This means that dangerous goods packages, which do not exceed certain quantity limits per outer and inner packaging gain relief from the dangerous goods regulations. This relief is a simpler regulatory alternative to preparing all hazmat shipments as fully regulated.



This hazmat shipping option may pose a lower risk during transportation of hazmat by air than shipping hazmat in larger quantities. The shipper will benefit from some exemptions such as the strict packaging requirements, provided that a limited quantity of hazmat is properly packaged and labeled.


Furthermore, using the limited quantity Hazmat option, the shipper wishing to ship hazmat by air can save considerable costs for packaging and shipping.


DG classes are permitted in a limited quantity

Only dangerous goods which meet the criteria of the following classes, divisions, and packing groups (if appropriate) may be carried under the provisions for dangerous goods in limited quantities:

Limited Quantity Packaging Requirements

General Packaging Requirements

Limited quantities of dangerous goods must be packaged per the general packing requirements.


Limited Quantity Packing Instruction

Limited quantities of dangerous goods must be packaged per packing instructions indicated in column G of the list of dangerous goods – table 4.2- in IATA Dangerous Goods manual and which is identified by the prefix letter “Y”.


Furthermore, a Max weight of 30 kg (approx. 66 lbs) per package, and single packaging, including composite packaging, are not permitted.

Note: refer to the current  IATA Dangerous Goods manual, and you must adhere to specific packaging requirements for the DG Class you are shipping.


Package Performance Test

Drop Test:

The package as prepared for transport must be capable of withstanding a 1.2 m drop test onto a rigid, non-resilient, flat, horizontal surface, in a position most likely to cause the most damage.

Stacking Test:

Each package offered for transport must be capable of withstanding, without breakage or leakage of any inner packaging and without significant reduction of effectiveness, a force applied to the top surface for 24 hours equivalent to the total weight of identical packages if stacked to a height of 3m (including the test sample).


The List of Dangerous Goods – IATA DGR Table 4.2

I will give you an example, using the IATA DGR manual- table 4.2- list of dangerous goods. In this example, we will review all information regarding one dangerous good substance from class 2 dangerous goods.

As you see in the below image, you can ship Acetal, UN 1088 by using a limited quantity provision. You must adhere to these dangerous goods instructions:

IATA DGR Table 4.2

The total net quantity per package must not exceed 1 Litter.

The inner packings must not exceed, each:

  • For glass inner packaging: 0.5 litter
  • For Metal inner packaging: 0.5 litter
  • For Plastic inner packaging: 0.5 litter

You may ask, form where I got this information regarding the quantities for inner packaging.

Well, the substance of each dangerous good has its packing instruction – see the image below- for Acetal, UN 1088, the packing instruction is Y341.

 Simply, search for packing instruction Y341 in IATA DGR manual ed63 section 5- packing.


Now, what about 2 liters of Acetal, UN 1088?

Simply, you have two options:

First: you can ship it by air using a limited quantity provision, but you should pack it in 2 packages each one must not exceed 1litter.

Second: you can ship it by air – passenger aircraft- using UN specification packaging which is already tested and has a UN mark. See the image, column J, you can ship up to 5 litters per UN specification packaging. Let this for another article on the aviation professional website.


Let us move to the dangerous goods marking – limited quantity

Marking on The Limited Quantity Package

Before explaining the labeling requirements for the limited quantity hazmat, you need to know the marking on the package.

Each dangerous goods package must show the following;

  1. The proper shipping name(s) of the contents. See the image above column B.
  2. The corresponding UN number(s) or ID number(s) for the dg substance. See the image above column A.
  3. The full name and address of the shipper and the consignee. See the air waybill.
  4. The net quantity of dangerous goods contained in the DG package. For our example it is 1 litter, see the image above column H.
  5. For limited quantity provisions, the DG package must be marked with the Limited Quantities mark (s), see the image blew.

Hazards labels on the Limited Quantity Package

Simply, we refer to the IATA DGR manual- table 4.2.  For Acetal, UN 1088, See the image above column D (hazards labels). It tells us that the label which must be fixed on the dg package is a “flammable liquid label”.

Handling labels on the Limited Quantity Package

Simply, it depends on the nature of the dangerous goods substances. By referring to IATA DGR manual ed63, a package orientation label is required for dangerous goods in an inner packaging that 120ml or less. See the image below.

How our limited-quantity package looks like

In our example, UN 1088, Acetal. we will refer to the IATA DGR manual- table 4.2.  For Acetal, UN 1088, See the image above table columns A, B, E, D, H.

I will mark each letter in the package for you to understand the Limited Quantity Hazmat Placard and other marking and labeling requirements. See the image below with red-colored letters A, B, E, D, H.

In hazmat shipping, shippers may select shipping dangerous goods by using the term known as limited quantity hazmat. A limited quantity exemption may apply to DG shipment if shippers are shipping small quantities of dangerous goods.

Please note that class 1 dangerous goods explosives cannot be transported in a Limited Quantity. Furthermore, some states and airlines have variations that forbid limited quantity packaging.

Note: I am using different dangerous goods terms in this article because of search engine optimization . for example : Placard =Mark =Label , Hazamt=Dangerous Goods.
