Not allowed. Pepper spray and mace are prohibited in carry-on bags entirely, regardless of container size.
Checked-bag details
Allowed with conditions. You may pack one container, up to 4 fl oz (118 mL), in checked baggage, as long as it has a safety mechanism (such as a safety cap or lock) to prevent it from discharging accidentally. The spray must also contain no more than 2% by mass of tear gas agents (CS or CN). Many airlines restrict or ban pepper spray outright even when TSA allows it, so confirm with your airline before packing it.

Special instructions
Only one 4 fl oz (118 mL) canister per passenger, checked bags only, and it must have a working safety mechanism against accidental discharge. Check your airline's own policy, since some carriers prohibit pepper spray even when TSA permits it, and some countries restrict or ban possession of it entirely.
