Under these rules, is UN3090 allowed at all locations?

• A. Only where UN3090 is not prohibited
• B. Yes, at all locations
• C. Only at airports
• D. Only in the country of origin

Answer: (A)

Shipping dangerous goods depends on the destination’s rules. Not every location allows UN3090 everywhere; some places prohibit lithium metal batteries or restrict how they can be shipped. Because of these location-based restrictions, you can move UN3090 only to places where it is not prohibited. If a destination or carrier policy bans it, you can’t ship there, even if other locations permit it. So the correct understanding is that UN3090 is allowed only at locations where it is not prohibited.
