Artikel 9

1. The weight to be declared on temporary importation papers is the net weight of the vehicles. It shall be expressed in the metric system. In the case of papers valid for one country only, the Customs authorities of that country may prescribe the use of another system.
2. The value to be declared on temporary importation papers valid for one country only shall be expressed in the currency of that country. The value to be declared on a cornet de passages en douane shall be expressed in the currency of the country where the carnet is issued.
3. The articles and tool-kit which form the normal equipment of vehicles need not be specially declared on the temporary importation papers.
4. When the Customs authorities so require, parts (such as wheels, tyres, and inner tubes) and accessories not considered as constituting the normal equipment of the vehicle (such as radio sets, trailers not declared on a separate document, or luggage carriers) shall be declared on the temporary importation papers with the necessary particulars (such as weight and value) and shall be produced on exit from the country visited.
