Not OP, so I could be wrong about this, but I'm guessing that his issue is strict customs and not A being unwilling to ship N to his country, seeing how I'm not familiar with him refusing to ship to specific countries with the exception of Mexico. In that case it wouldn't make much of a difference since it would still have to pass through inspection. Perhaps they're less thorough about checking packages sent from Europe or the US than those sent from Mexico, but even if that's true, a package with two bottles containing liquids would still arouse suspicion.
