Imagine returning home from a trip overseas only to be questioned by authorities about the Hermès Birkin you’ve owned for years or the Cartier bracelet you’ve worn on countless occasions. While it might seem unlikely, US Customs and Border Protection (CBP) officers can ask travelers to prove that valuable belongings were already in their possession before leaving the country. Without the right documentation, establishing prior ownership may not be as straightforward as you think.

A recent incident at Philadelphia International Airport is an expensive reminder of why this matters. U.S. Customs and Border Protection (CBP) officers seized more than $250,000 worth of undeclared Cartier jewelry from an American passenger arriving from Amsterdam. The haul included a bracelet valued at $183,818 and a ring worth $67,811. The passenger acknowledged the purchases only after officers revealed they already knew about the items, and CBP initiated proceedings to revoke her Global Entry membership.

While the jewelry in this case had been purchased abroad, it raises an important question for anyone traveling with luxury goods: if questioned by customs officials, how can you prove that your watch or handbag were taken on the trip, rather than purchased during it? Your word may not be enough.

Not to worry, there are steps you can take before embarking on this season’s Thanksgiving and holiday travels to ensure your luxury belongings are ready for the journey. This three-part guide covers the key considerations at every stage of the journey, from documenting the pieces you already own before departure to packing and protecting your handbags along the way, and understanding customs requirements when shopping abroad.

Document Your Luxury Belongings Before Departure

There are several ways to show that valuable items you’re bringing home were not purchased abroad. One of the simplest is to take photographs before you leave. Capture recognizable details of each piece and, if possible, include a dated newspaper, such as a copy of USA Today, in the frame to provide a visual reference for when the photos were taken. This provides a visible reference to when the photograph was taken, rather than relying solely on its digital timestamp, which can be altered.

It’s also a good idea to keep a list of the valuable items you’re taking, noting details such as the brand, model, serial number or other identifying features. Original receipts are useful too, although not everyone keeps them, particularly for pieces purchased years ago. Appraisals and insurance records can also help establish prior ownership.

For additional peace of mind, and with advance planning, US travelers can consider CBP Form 4457, the Certificate of Registration for Personal Effects Taken Abroad. This allows you to register your belongings with CBP before departure, creating an official record that they were already in your possession before traveling.

Form 4457 is available directly from the CBP website and requires you to list the items you’re traveling with, including their descriptions and identifying details. Before your trip, take the completed form and the listed items to a CBP office for inspection and certification. It’s worth checking your local office’s opening hours and whether you need to make an appointment, so you can factor the visit into your pre-trip preparations.

What, If Anything, Do You Need to Tell French Customs When Travelling with Luxury Items?

Of course, customs considerations don’t end in the US. Let’s say you’re travelling to Paris for a little luxury shopping. Alongside thinking about what you might bring home, it’s worth understanding the customs considerations for valuable belongings you already own and are taking with you.

Generally, you won’t need to take any special steps or pay import duty simply for bringing them into the country. However, French Customs could ask you to demonstrate that valuable items were already in your possession before your trip and that any applicable duties and taxes have been paid.

As with the US CBP, photographs, receipts, appraisals and insurance records can help support prior ownership. If you travel to France frequently with valuable belongings, you might also consider a carte de libre circulation (Free Movement Card). This free document, issued by French Customs, helps establish the customs status of personal belongings. You can obtain one from a customs office by presenting the items and supporting documentation.

Taking a Luxury Item Abroad for Repair?

A trip to Paris might present the perfect opportunity to have a handbag repaired or a watch serviced, but taking a valuable item abroad for maintenance requires a little extra planning. After all, the last thing you want is to face unexpected import duties or fees when bringing or shipping your own item home.

Before leaving the US, you’ll need to complete CBP Form 4455, the Certificate of Registration, and present both the form and the item to a CBP officer for inspection. This creates a record of the item being temporarily taken abroad for repair, helping distinguish it from goods purchased overseas.

If the work substantially improves the item or increases its value, such as adding diamonds to a watch or upgrading a strap, additional import duty may apply. This is different from routine maintenance, such as having a handbag cleaned or repaired. If the item is replaced, exchanged or upgraded, ask the supplier to document the work and any difference in value on the invoice. Be sure to keep the repair invoice and declare the item to CBP when you return.

A Little Preparation Goes a Long Way

Part of the pleasure of travelling is enjoying the things you’ve collected along the way, whether that’s carrying a favorite Hermès handbag through Paris or wearing a treasured piece of jewelry to dinner. A little preparation can help you avoid unnecessary customs questions and unexpected costs, leaving you free to enjoy your trip with greater peace of mind.

But there’s more to preparing your luxury goods for travel than documentation. In Part II of our series, we’ll turn to the art of packing: from handbag nesting and choosing the right carry-on to protecting your favorite pieces in transit. Because how you pack can be just as important as what you take.
