No, we explicitly rejected a customs union. Customs union would result in no customs (though probably not as you'd have to also be part of the single market to eliminate all checks). The free trade agreement is different, and a step down from that. Given the amount of trade I think the customs fees will come down significantly over time once things are bedded in a bit more.
