This chart shows which goods are illegal for each faction. If you get caught shipping these goods in 'illegal' sectors, you risk having your goods confiscated, loose recognition, and or getting attacked!

Some tips when transporting these goods - if you have to travel in sectors where the goods are illegal, avoid at all costs “core” sectors or you will most likely be BUSTED and will lose reputation or risk being shot down.

I've been successfully moving Spaceflies and Space Fuel sticking to border sectors and traveling through pirate lanes whenever possible.
