If the item that you are trying to ship is deemed Hazmat you may have an additional fee added to your order when you check out. Items are deemed Hazmat as per the Section 14 Transport Information located in the item's Material Safety Data Sheet (MSDS). Sorry, but things that can go "boom" are hard to ship and we have to pass on our fees.
There is not "one-size-fits-all" fee for Hazmat shipping, the fee will vary depending on a variety of factors, such as what types of items you are buying, the size of the order, or the shipping method selected. If you have any questions about this subject, feel free to Contact Us at any time!
