Carnet mail

You're referring to a "carnet de passage en douane" or "CPD" for short, also known as a "temporary importation bond" or "TIB".

A carnet is a special type of customs document that allows travelers to temporarily bring goods into a country without having to pay duties or taxes upfront. It's commonly used by professionals, such as photographers, journalists, and artists, who need to transport equipment or materials across international borders.

Here's how it works:

1. The traveler applies for a carnet through a national association or chamber of commerce.
2. The carnet is issued for a specific period, usually up to 12 months.
3. The traveler lists the goods they plan to bring into the country on the carnet.
4. When the traveler arrives at the border, they present the carnet to customs officials.
5. The officials inspect the goods and verify that they match the items listed on the carnet.
6. If everything is in order, the traveler is allowed to bring the goods into the country without paying duties or taxes.
7. When the traveler leaves the country, they must return the goods and present the carnet to customs officials again.

Carnets are commonly used for:

• Professional equipment, such as cameras, lighting, and sound gear
• Artistic materials, such as paints, canvases, and sculptures
• Musical instruments and equipment
• Medical equipment and supplies

Keep in mind that carnets are not the same as a regular customs declaration, and they may have specific requirements and restrictions. It's essential to research the requirements for the countries you plan to visit and ensure you comply with all regulations.
