Shipments to Puerto Rico, Non-hazardous substances, the Overpack label, and Aviation Regulated Liquids or Solids
Welcome back to the Regulatory Helpdesk where we answer your dangerous goods & hazmat questions. We’re here to help you become independent with – and understand the whys and hows – of the regulations.
Shipping to Puerto Rico
Q. If 49 CFR is used to make a vessel shipment of limited quantities from the mainland US to Puerto Rico is a shipping paper required? I’m asking because limited quantities don’t require shipping papers.
A. Technically that is true. Shipping papers are not needed for US GROUND shipments. You have to read the fine print in paragraph 173.150(b) which is the section on limited quantities for flammable and combustible liquids. It that paragraph it says, ” … is not subject to the shipping paper requirements of subpart C of part 172 of this subchapter, unless the material meets the definition of a hazardous substance, hazardous waste, marine pollutant, or is offered for transportation and transported by aircraft or vessel, and is eligible for the exceptions provided in §173.156 of this part“.
Non-hazardous substances under WHMIS 2015
Q.Customer called and asked if SDS’s were required for non-hazardous substances and where to find this in the WHMIS 2015 Regulations?
A.The answer to your question can be found below in WHMIS 2015, which states that safety data sheets only pertain to a hazardous product, therefore Continue Reading…

UN Numbers on Explosive Placards
Q.Can the UN number be added to a class 1.4 placard shipping UN0323 ground in the U.S?
A. 49 CFR 172.334(a) States no person may display an identification number on Explosives 1.2, 1.2, 1.3, 1.4, 1.5, or 1.6. In this case 0323 is classified as a 1.4, So it cannot display the ID number.
Q. Section 18.104.22.168.1 has changed with the Dec 2017 Corrigenda to the IMDG. Why would you need to put a proper shipping name on a CTU when a placard is all that is really required?
A. First of all that section speaks specifically to 3 situations where information beyond a placard is required. The 3rd one really doesn’t exist anymore, but the first 2 do. The first is when you have a TANK cargo transport unit. Tanks as defined in Section 1.2 are those that are portable tanks, road tank-vehicles like gasoline highway trucks, and rail tank-wagons which are those rounded rail cars that you see. The second is when you have bulk containers. For either of these situations a placard is needed as well as the PSN. Given the corrigenda the height Continue Reading…
The formalization of the overpack concept into the Canadian TDG regulations has been the subject of concern for domestic shippers of dangerous goods due to the wording for fully regulated (TDGR 4.10.1) products. The wording implies that even when the DG safety marks for packages within the overpack are visible, the overpack must still have an “OVERPACK” mark displayed. This leads to some additional labelling requirements, particularly for shippers of stretch-wrapped pallet loads.
We’ll pause to review the concept of an overpack, consistent among the various regulations (e.g. TDG, UN Model Recommendations, IMDG, IATA, & 49 CFR).
An overpack is non-standardized packaging that:
Is used for handling convenience (e.g. to reduce multiple handling- I.e. 4 drums on a skid, allowing loading 4 at once rather than 4 trips, or 6 small containers in a “non-spec” master carton, or 48 small boxes stretch wrapped on a skid; a keg (small drum) in a non-spec box for stability, etc. )
Cannot be used as a replacement for inadequate, required “standardized” packaging
Is to be unopened between consignor and receiver
Cannot interfere with the integrity of the standardized packaging (e.g. banding cutting into boxes on a pallet)
The common principle requires that the description of DG that cannot be seen once the overpack is in place will be reproduced on the outside of the overpack.
