Certain items such as lighters are considered “hazardous materials.” This means that there are shipping restrictions and additional charge involved in transportation. Where these apply, the HazMat fee has been embedded into the items pricing. Only ground shipping is available on hazardous materials, rush shipping is not available. These items can only be shipped domestically within the contiguous United States, for other locations a freight forwarder may be necessary. For these reasons, hazardous material items are not available as free samples.
