Common items like nail polish, perfume, and hair spray are considered hazardous material, and require special procedures when shipping them.

It's important to read all the USPS rules about Hazardous Materials when shipping anything considered dangerous. You are liable for any failure to follow the rules. 

For common, less-hazardous items like perfume, you're simply not allowed to use air-based services like First Class Package, Priority Mail, and Priority Mail Express. This means Parcel Select Ground is your only option. You also need to follow a few steps, explained below.
