Shipping Hazardous Materials in E-Commerce: Rules and Limits.

Dangerous goods include, among other things, batteries, aerosols, flammable liquids, and certain cosmetic products. The shipment of such items is subject to strict international regulations such as ADR (road transport) or IATA (air freight).
Hazardous materials must be specially packaged, properly labeled, and accompanied by the appropriate documentation. Errors can result in substantial fines and rejection by the shipping carrier.
Not every fulfillment provider is allowed or able to store and ship hazardous materials. A specialized partner understands the legal requirements and handles the entire shipping process in compliance with regulations, including in the areas of food and cosmetics fulfillment.
Anyone who sells hazardous materials should work with an experienced, certified fulfillment partner early on to avoid legal risks.
