Mmm, good observation. Possibly he's assuming that goods coming in from the EU aren't even checked by Border Farce, so he doesn't bother requiring a defence. After all, he's not subject to UK laws, it's purely an economic question of whether the toy gets delivered, returned, or destroyed.
It does seem to mostly be US and Far East air mail shipments that people report being stopped, rather than stuff being trucked in from the Continent.
