Any explosive good (or bad) to be transported has to be officially labeled with the Explosive label and a respective class number indicating the intensitiy of the hazard. Of course, the hazard (explosion) usually has to be triggered manually, unlike on the flammable or spontaneously combustible deliveries.

CSGO10 anniversary:
It's pretty hard to confuse this label's meaning to be honest so what's the use of a description? Anyways, put it on your C4. Oh wait you can't.

The Explosive Charge label for C4 grade explosives comes in standard yellow as a paperback sticker, aswell as a bright orange holo sticker and a goldlike foil variant.

Scraping this label let's the explosion remain, just as would happen when not properly labeling explosives.
