We have a load going from Spain to Belgrad,Serbia. T-form is prepared in Spain to the Slovenian/Croatia border. From what i understand we then need a transit document through Croatia to the Serbian border. Can anybody advise on this as it is a new route for us, Will it be a similar thing to Swiss transit ■■ Thanks in advance.
i can’t give an answer for your exact question.
however, i know some bulgarians that double man every week to spain. they don’t bother going via croatia. they say it’s too much hassle. they use hungary, and slovenia. longer distance, but a much shorter time.
Ive never done Swiss so can’t coment on that process but I do Kosovo regularly and transit Serbia and have in the past transited Croatia for Montenegro. When you reach the Slovenian/Croatian border you will have to declare that the goods have left the EU, this will be done on the Slovenian side. Croatian customs will then make a new set of papers to transit, depending on what your load is and the value will determine the costs for the papers, when you leave Croatia those papers will end and a new set of papers will be made up on the Serbian side to get you through to customs. I would imagine you will clear customs in Belgrade but sometimes you can clear on the border depending again on what your carrying and who the recipitant company are. Make sure you carry plenty of copies of the packing lists and the invoices/value of the goods, this make for an easier passage. Customs will charge for parking in the compound in Belgrade, its just another money making scam. If your carrying and food products make sure you have the correct docs, I spent 5 days on the Serbian side of the Hungarian/Serbian border because I did not have DEFRA certificates for the rice I was carrying. I was only tansititing Serbia for Kosovo and my load was humanitarian aid but they where a total pain in the rear. If your staying over night in Belgrade there is the National Hotel where you can park and get a meal and shower in the hotel. Let me know and I will give you directions as it is now within the 7.5 ton truck ban.

On the Croatian custom terminal you can feel that you traveled back in time.
This was less than two years ago, they also had a computers with monochromatic screens (do I need to say that they were kinescopes?) and needle printers, everything was in text mode… 
Ah, and nobody speaks English, French, German, Czech or Polish, and acording to some Hungarian drivers, Hungarian, despite that I was on Hungarian border…
Thanks for your advise guys, will let you know how we get on…
