There may have been some change to HazMat rulings.

If anyone knows how to search HazMat rulings and regulations, please take a go at it.

Quote:

# Flammables less than one Gallon are available to certain areas within Canada via UPS Ground. Please call to see if your city qualifies.
# Please call for details on shipping flammables to areas outside of the United States or Canada.
# Butane Canisters are an exception, all canisters may only ship UPS ground and only to the lower 48 states. 8oz canisters incur a $35 HAZMAT fee for shipping. NRS can ship 1-4 eight oz butane canisters in one hazardous materials box, which would incur only one $35 fee. Each additional box will incur a $35 fee.
