Yes, SA matches are classified as HAZMAT.
Seems that SO many people are worried about the danger in every item that the benefits are ignored.
Sign of the times, people are so pampered that it's no wonder the general population (does not apply to forum members) is virtually helpless if the American Express card is not the solution.
You know people who wish to make explosives can still find the means, so it accomplishes absolutely nothing to make the world safer, It does create strange paradox's though. In order to buy SA matches recently I had to buy many more boxes online than I wanted in order to make the HAZMAT charge justifiable.
While I have some REI matches as well SA are the main stay of my kits.
