Aerosol cans get a new definition, making it easier to ship them internationally

The US Transportation Department is changing how it defines an aerosol can. This will make it easier for companies to ship aerosol products like hairspray and bug spray across borders, aligning US rules with international standards.

For years, US rules for shipping aerosol cans were stricter than international ones. This meant companies had to deal with extra paperwork and costs when sending products abroad or bringing them into the US. This change removes that friction, making global trade in these common products simpler and cheaper. It's a small technical tweak that smooths out a common logistical headache for manufacturers and retailers.
