At Carlile Transportation, shipping hazardous materials is critical across multiple transportation modes: ground (49 CFR), air (IATA DGR), and vessel (IMDG Code). The regulations for shipping limited quantities can vary between these modes.
Ground (49 CFR): Part 173 packaging instructions in Column 8A of the 172.101 shipping table. The maximum allowed is 66 lbs. per package.
Air (IATA DGR): Packing instructions in Section 5 in Column G of the IATA DGR 4.2 DG List. The maximum allowed is 66lbs per package. (detailed in Column H of the IATA DGR 4.2 DG List.)
Vessel (IMDG Code): Packaging instructions in Column 7A of the IMDG Code 3.2 DG List. The maximum allowed is 66lbs per package.
No more than the below quantities can be shipped per mode of transportation. If more quantity is shipped then it is no longer considered Limited Quantity.
If a shipment is moving across multiple modes of transportation then the shipper needs to package and adhere to the strictest guidelines of the mode being shipped.
Example 1: Shipper >> Truck >> Ocean >>Consignee
The strictest mode is Ocean, therefore the freight and paperwork must be packaged for Ocean shipping.
Example 2: Shipper >> Truck >> Ocean >> Air >> Truck >> Consignee
The strictest mode is Air. Therefore the freight and paperwork must be packaged for Air shipping.
No matter how you ship the shipper is responsible for shipping to the strictest mode that the freight is travelling on. All modes of shipping (truck, air, ocean) have regulations that limit the amount aka quantity of hazardous materials/dangerous goods allowed in inner packaging.
All modes require strong outer packaging for limited quantities of hazardous materials
Shippers are not required to use UN specification markings.

Freight that falls within Limited Quantities still needs to be packaged for the strictest mode.

LABELING RESPONSIBILITY
It is the responsibility of the shipper to not only package and tender the paperwork to the transportation carrier. It is also the responsibility of the Shipper to properly sticker the pallets, and boxes with the appropriate hazmat markings.
The Shipper is also responsible for providing the transportation provider with the appropriate equipment hazmat markings to be placed on the trailer and/or container. 49 CFR 172.516
Hazmat employees must undergo training to ensure compliance with the latest regulations. This includes general awareness, function-specific, and security awareness training. Recurrent training is required every three years for ground and vessel shipping and every two years for air shipping.
