Carnets and insurance: taking jewelry across a border for a show
How an ATA carnet works, why declared values matter more than exhibitors expect, and what a jeweller's block policy covers once the goods leave the vault.
The hardest part of exhibiting abroad is not the stand, the flights or the hotel. It is the hour at a customs desk with a case of goods that belong to you, in a country with no reason to believe you will take them home again. Every border treats an inbound jewelry case as an import, taxable on arrival, unless you can document that it is only visiting.
Two documents answer that. One is a customs paper saying the goods are temporary; the other is an insurance policy saying who pays if they never come back. Both must exist before you leave, both must describe the same goods at the same values, and neither can be arranged at the airport.
What an ATA carnet actually is
An ATA carnet is a temporary admission document recognised across most of the trading world, issued at home by the chamber of commerce acting as guaranteeing body. It is a passport for goods: valid twelve months, good for several trips, backed by a security you post up front, usually a bond or cash deposit set as a percentage of the declared value. The security exists so the destination can collect the duty and tax it would have charged if the goods turn out not to leave.
The limitation surprises first-time exhibitors most. A carnet covers samples for display, not goods for sale. If a piece sells off the stand it has to be regularised with local customs, the duty and local tax paid, and that line discharged before the rest of the case goes home. Much of the trade designs around this: show on the carnet, write orders at the stand, ship from home afterwards. Coverage is not universal either. Some major destinations for jewelry sit outside the system, usually because they charge no duty, and some countries inside it exclude precious stones. Ask the issuing chamber which of your cities it covers.
The stamps and the values
One trip generates four endorsements: exportation from home, importation at the destination, re-exportation when the show closes, re-importation on return. Each is a counterfoil an officer signs and stamps, and a missing stamp is the expensive failure, because an unstamped re-exportation looks exactly like goods that stayed and sold. The claim lands on the guaranteeing body and then on you: duty, local tax, penalty. Find the customs desk before you check in, and confirm its hours before booking the flight home. It is rarely near the gates and not always staffed late on the Sunday a show ends.
Declared value is replacement value, line by line, not your cost and not an optimistic retail figure. Understating to shrink the bond is a false economy twice over: it invites a penalty if customs revalues the case, and it caps what you can credibly claim if goods are lost. Overstating raises the security and slows the inspection. The list should match your insurance schedule item for item: an adjuster and a customs officer looking at the same case should read the same document.
- An itemised list, one line per piece, not a lump sum by tray.
- Weights, grades and report numbers for stones; serial numbers for watches.
- Country of origin and of manufacture on every line.
- Replacement value per line, in one currency, matching the insured schedule.
- Photographs of each piece and tray as packed, dated before departure.
- Hallmarks, maker's marks and identifying engraving.
What the policy covers once the goods leave the vault
A jeweller's block policy is the trade's standard cover, and the part that matters for a show is the part few people read: the off-premises limits. Cover at your own premises says nothing about cover in a hall four thousand miles away. Policies commonly cap goods away from the business at a fraction of the main limit, exclude certain territories, and require an exhibition endorsement before a show is covered. The exclusions have a pattern, and each describes something exhibitors do routinely: goods in an unattended vehicle, in a hotel room rather than a safe, out of a locked case overnight, in checked baggage.
That last one is why the specie carriers exist. Insured door-to-door transit, with the goods in a vault at every stop and a signature at every handover, costs more than a flight with the case on your knees and is easier to claim against. Hand carriage suits a small parcel on a short route, but only if the policy says so in writing and the goods were registered with your own customs on the way out, so their return is not itself treated as an import. If anything is travelling on memo, settle whose policy answers for it in transit.
A carnet proves the goods were only visiting. The policy decides who pays if they never come home. Start both four to six weeks out, not four days.
Valumira runs twelve cities between Las Vegas in November 2026 and Sydney in October 2027, which is ten customs regimes for anyone doing the full series, and the paperwork is easiest as a standing list amended rather than rewritten each month. Each show opens on Friday for the trade before the two public days, which makes Friday morning the wrong time to be in a freight office. Antwerp in June 2027 adds a layer, since rough diamonds travel under their own certification regime and a carnet substitutes for none of it.
