Aeorosol spray cans containing hazardous materials are prohibited but "consumer commodities" dispensed in this type of containers such as dust cleaner, ant killer, paint, window cleaner, or WD-40 can be easily shipped without much restriction. Here are some tips on how to safely and successfully ship aerosol spray cans.
Wrap the each aerosol can in bubble wrap. Arrange the cans in an inner package and then place this in a strong outer package. Each package of aerosol cans should not exceed 66 lbs.
The next key step is properly labeling the packaging. In this case, label your package: Consumer Commodities ORM-D shipping class.
The ORM means Other Regulated Materials, and the D is the packaging group.
Place this label near the location of the shipping address so that it is most likely to be seen by the carrier.
No other marking, labeling, or hazardous paperwork is required, and the package must be shipped via Ground transportation.
