We arrived in the afternoon at this one-stop border. We drove straight to the main building and went to the Ministry of Health’s window. They issued us a health certificate, which nobody ever requested (they did not check any vaccination certificate or temperature). For the truck, they issued a “Certificate for free pratique of motor vehicle” for the fee of 10000 TZS, which we paid in the bank (1 USD / 2550 TZS). They said it’s valid for 30 days, so it can be used multiple times to cross Tanzanian borders.
Then we proceeded for the Rwandian exit stamp. After that, we applied for the Tanzanian transit visa. We filled out the application form, paid the officer 30 USD in cash, and got the stamp in the passport. The next window was a quick exit stamp into our CPD; they did not ask anything. Following window processing Tanzanian TIC for cars, but since we had CPD, they sent us to the booth near the exit gate, where they stamped it, and we could drive out.
In the meantime, we bought Tanzanian SIM cards (Vodacom—sim card 2000 TZS, 10 GB / 30 days / 20000 TZS). The officer of the Ministry of Health briefly checked the truck and asked us to show him the dust bin and first aid kit. Then, we drove out without any customs check to the exit gate, where the officer controlled the stamp in our CPD. It was a pretty efficient border without annoying fixers, and all procedures took us around an hour and a half.
