You will have to pay import taxes. And they can be steep depending on what you are bringing and the value of it.

Tunisia's import duties range from 10 percent to 287 percent. Certain luxury, durable goods (such as automobiles), or consumer items are also assessed a consumption tax that can be as high as 500 percent. Tunisia calculates its Value Added Tax (VAT) on the base price of the goods plus any import duties,
surcharges, and consumption taxes. The Ministry of Finance (which oversees the Customs Service) is responsible for determining the duties and taxes of specific imports.

I moved here a little over 5 years ago. I highly suggest you sell your stuff and start fresh here. The price to ship your things, plus the import taxes will make it a lot more costly than if you just bought new stuff. Tunisia has some really nice and good quality items here and they are reasonably priced. For example, to completly redo my kitchen (install cabinets, buy a microwave, oven, stove, refridgerator - the works) we paid between 3,000-4,000TND - that's less than 3,000USD. That's about 80% cheaper than what it would cost to get the same quality in America.

Hope this helped. If I can be of any other assistance, feel free to contact me.

contact the consulate , when I moved to Spain I never paid anything

I moved from UK to Egypt about 5 years ago. The removal company said they checked and I would NOT have to pay import duty as the goods were for my own personal use, they were not new. When the good arrived, I got a message from the removal company that they had confiscated my xerox, because it was a fax/scanner and printer in one machine and as I am not a business I was not allowed to own it! then they charged me such a high import tax that it would have been cheaper to have scrapped the lot in UK and brought new here. The gave me 7 days to pay and said if I didn't they would charge me 100le a day storage and if I didn't pay in 31 days they would scrap the container. My other choice was to pay to have the whole container sent back to the UK. I had to pay because everything I owned was in that damn container. but this isn't EU so maybe its different. Good luck with your move. hope you'll be happy in Tunis
