I had a huge problem with customs but a lot of that was due to Covid. I could not find a customs broker on the internet and eventually found one who left a lot to be desired.
You may have heard that you can bring household effects into the country duty free but there is, of course, a catch. The liability for duty cannot be released until you have full legal residence, so you will either have to deposit the notional duty or buy a guarantee. Furthermore, (according to my agent) the goods cannot be released until the owner is in the country. It took my agent 4 months, after my arrival, to release my container from the bonded yard while it was accruing storage fees of over $400 per month. It took a further 3 years to release my liability for duty because the directorate responsible for national identity, made a mistake and wouldn't admit the mistake until 3 separate visits from lawyers made them see the light.
Below is a list of customs brokers advised by Uruguay Customs. My agent doesn't appear on the list, which is reassuring.

You may have to contact several before one replies to you. Government departments are wont to make mistakes so take a screenshot of any fugitive messages or receipts and check thoroughly to ensure that your details have been entered correctly.
