So you've ordered a doll and feel pretty good about yourself. She's been made at the factory and has shipped out. So far, life is great and then Customs gets involved and dammit! everything grinds to a halt or is suddenly not so straight forward. Well, thankfully, this doesn't happen too often and if you're dealing with a legitimate company, then parcels will likely sail through the process or be delayed by just a few days
What is customs though?
Each country has a Border Force that is responsible for checking two things: 1) that parcels entering into the country fall within the laws of that country and 2) that the appropriate tax or tariffs are paid on them. Many people try to illegally import all kinds of items, from drugs to guns, and also try to pay less tax than they should - so Border Force is given a lot of power to deal with this. They are, in effect, the law on parcel importation.
That said, the UK Border Force does not have a problem with sex dolls, as long as they are considered adult and the correct amount of tax is being paid. This is why it's always best to purchase from a reputable dealer who is, ideally, located in your country - as they are best placed to abide by local laws. Note that even if your doll is an adult doll, customs may still want to take a look and may hold on to it for a few days. This is simply a matter of logistics, as they pull some out at random and then need to coordinate an officer to look at a few at the same time. Once they've checked them, they will be cleared or denied, depending on the features. So if you've bought from a good company, relax and just wait for the update that your parcel has cleared customs.
