Why are some products marked as a "No-Fly Item"?
There are certain items and materials that are not allowed by The International Civil Aviation Organization (ICAO) and Department of Transportation (DOT) to ship via air shipments. A typical reason for this is a low flashpoint of the material being shipping. These items are only allowed to ship via Ground UPS on our site in order to be compliant with such regulations.
If a product has shipping restrictions you will see the "No-Fly Item" Icon on the product description page Click for More Info.
