We're planning on shipping some items from the US to Australia as you cannot get them here, that being:
I have been in contact with a freight forwarder who can ship them to Australia, but obviously they will need to be shipped as a hazmat item and go inside a particular sized box and be shipped by FedEx or DHL.
Now, as I understand it, the reason these are classified as hazmat is because of the chance of bursting as well as being flammable.
As per the link above:
Contents under pressure. Do not puncture or incinerate container. Do not set on stove or radiator, expose to heat or store at temperatures above 120°F (49°C), as container may burst.
I have no idea, but I assume they wouldn't be exposed to high temperatures such as that during shipping, but my question is...
Assuming we got them ok and they didn't burst, do pressurised cans such as these still pose a risk to bursting in "normal" conditions AFTER they have been exposed to high heat? Such as if they had been exposed to high heat during shipping, but we got them ok, would they still pose a risk to us with the possibility of bursting?
The manufacturer provides a Material Safety Data Sheet on their website, which you have to email them or register to get it sent to you, but if it's of any interest you can download it here from MediaFire.
Alternatively you can find instructions to download it via their site - see under "PRODUCT SAFETY INFORMATION".
If you don't want to download anything then you can see screenshots of the document I uploaded to an Imgur gallery here: https://imgur.com/a/gXKxVeE
Note though, the above data sheet was provided via their site that shows their old packaging, the link from Chewy above shows their new packaging, as far as I know the packaging is the only thing that has changed.
