What it means
Customs authorities normally charge duty and tax when goods cross a border, because the default assumption is that the goods are being sold in that country. A carnet tells them the goods are only visiting, so nothing becomes payable provided everything leaves again within the validity period.
Carnets are issued by national chambers of commerce and accepted across a large network of participating countries. Three broad categories of goods are covered: commercial samples, professional equipment, and goods destined for trade fairs and exhibitions.
Camera crews, touring musicians, engineers carrying test rigs and sales teams with demonstration units are all typical users. The financial benefit is cash flow and certainty rather than a tax saving as such.
Without a carnet, a business either pays duty and tax that it must then reclaim through a slow refund process, or posts a separate temporary import bond in every country on the itinerary. A single carnet can be valid for up to twelve months and can cover multiple trips and multiple countries on one document.
The issuing body charges a processing fee and requires security, commonly a cash deposit or an insurance-backed guarantee, sized on the duties and taxes that would otherwise be at stake. The discipline required is paperwork.
Every entry and exit must be stamped by customs, and if an item is sold, lost, or simply not stamped out of a country, the guarantee is called and the full duty and tax become payable, usually with penalties added.
In practice
Real-world examples.
Example
A touring orchestra visits six countries with instruments insured for $2.4 million. One carnet covers the whole tour, and customs officers stamp the same document at each border rather than the group arranging separate clearances in every country.
Example
An oil services firm ships $600,000 of downhole testing equipment for a four-week survey. The carnet avoids a temporary import bond in the host country and, just as importantly, gives the crew a single itemised list that customs will accept on the way out.
Example
A jewellery house takes a sample collection to a trade fair and displays goods it has no intention of selling on site. The carnet keeps the samples duty-free, and the firm carefully records that nothing was sold, because any sale would immediately trigger duty on that piece.
Formula
Calculation
Duty and Tax at Risk = Goods Value x (Duty Rate + Import Tax Rate)
Carnet Cost = Processing Fee + Security Premium
A broadcast production company takes $180,000 of camera and lighting equipment abroad for a three-month shoot. In the destination country the applicable duty rate on that equipment is 5% and import tax is charged at 20% of the same value.
Duty = $180,000 x 0.05 = $9,000
Import Tax = $180,000 x 0.20 = $36,000
Total at Risk = $9,000 + $36,000 = $45,000
The carnet costs a $400 processing fee plus a guarantee premium of 1% of the amount at risk, which is $45,000 x 0.01 = $450, giving a total of $400 + $450 = $850. Without the carnet the company would have to tie up $45,000 for the duration of the shoot. Even at a 10% annual cost of capital, holding $45,000 for three months costs $45,000 x 0.10 x 0.25 = $1,125, more than the carnet itself, before counting the staff time spent chasing a refund afterwards.Case study
Seen in the real world.
Lantern Field Robotics is a fictional company invented to illustrate how carnets work in practice. It demonstrates inspection robots to mining clients and typically travels with about $340,000 of equipment across four or five countries a year.
Before adopting carnets, the operations manager arranged temporary import bonds country by country. On one trip the company paid roughly $58,000 in duty and tax up front in a single jurisdiction and waited eleven months for the refund, which sat as a receivable on a balance sheet that could ill afford it.
In this illustrative example the firm switched to an annual carnet costing a few hundred dollars plus a guarantee premium, and the up-front payments disappeared. The one painful lesson came when a technician left a damaged sensor behind for local repair without having it stamped out; the guarantee was partially called and the company paid duty on that item plus a penalty. The fictional story ends with a simple internal rule: nothing on a carnet leaves the team's possession without a customs stamp.
Watch out
Common mistakes.
- Selling an item that travelled on a carnet. The document only covers goods that will return, and any sale makes duty and tax immediately payable on that item.
- Missing an exit stamp. Customs treat unstamped goods as having stayed in the country, and the guarantee is called even if the equipment is sitting back home.
- Listing goods vaguely on the general list. Serial numbers and precise descriptions are what allow officers to match items on the way out, and loose descriptions cause delays and disputes.
Questions
People also ask.
What goods cannot travel on a carnet?
Consumable and disposable items, goods intended for sale, and most postal shipments fall outside the scheme, as do goods that will be processed or repaired abroad in many countries.
How long is a carnet valid?
Up to twelve months from issue, and within that period it can cover several separate trips and several countries on one document.
Is the security deposit refundable?
Yes, the deposit or guarantee is released once the carnet is discharged, meaning all goods are properly accounted for on return and the document is closed out.
