I can see American pack manufacturers taking advantage of this.
Doesn't HK usually ship their lipos labeled as a toy anyway. I don't think I have ever received a parcel from them with a lipo warning label on it.
I worked for UPS for quite some while, they never used to carry labels then everything known to have a lithium polymer battery had to have one of these.

Made it real easy for the a holes that worked at UPS to identify which boxes had the Apple products to steal.
