As part of Victoria 3, a customs union is a bilateral agreement between two nations where one nation agrees to submit its national market to another and be absorbed into an economic union, the devs begin their explanation in the latest dev diary .

This means that it is a diplomatic action, i.e. something that another nation must agree to because a customs union alone is not something that can normally be imposed on another nation .

A slight deviation from the above statement is possible, customs unions can be imposed using the bonds of the previously due country. This will only allow diplomatic action to take place despite the nation’s willingness to say no, it should not be able to override any other possible limitation in the game.
