Your Products Are Being Resold Where You Never Shipped Them: 6 Rules to Stop Gray Market Diversion

In 2013, the US Supreme Court ruled on a case that started with a graduate student and a stack of textbooks. Supap Kirtsaeng, a Thai student at Cornell, had his family buy English-language textbooks in Thailand, where the publisher John Wiley & Sons sold them for far less, and then resold them in the United States. Wiley sued. Kirtsaeng won: in Kirtsaeng v. John Wiley & Sons, the Court held that the "first sale" doctrine applies to copies lawfully made abroad.

The lesson for any company that sells in more than one country is uncomfortable. When you charge different prices in different markets, somebody will try to buy where you are cheap and sell where you are expensive, and the law will often be on their side.

That trade has a name: the gray market, or parallel imports. The goods are genuine. They are your own products, sold by you or your distributor. They simply turn up in a country, a channel or a price band where you never intended them to be.

Our group has sold in more than 75 countries since 1890, mostly through importers and distributors who each own a territory. Gray goods are one of the fastest ways to destroy that network, because they punish the partner who invested in your brand and reward the one who did not. These are the six rules I use to keep diversion under control.

What is a gray market importer?

A gray market importer buys genuine branded products outside the official distribution chain, usually in a cheaper market, and resells them in another market without the brand owner's authorization.

It is not counterfeiting. The bottle, the box or the machine is real. What is unauthorized is the route. That is why gray goods are so hard to fight: the customer often cannot tell the difference, and in many countries the reseller is doing nothing illegal.

The damage shows up in three places:

• Your authorized distributor loses margin and motivation. They paid for marketing, samples and sales staff; the diverter paid for nothing and undercuts them.
• Your price structure collapses. One cheap market becomes the real price everywhere.
• Your brand takes the blame for problems you did not cause: wrong labels, missing warranty, products stored badly in transit.

Rule 1: Find the price gap before the arbitrageur does

Gray markets are a math problem before they are a legal problem. Diversion happens when the price difference between two markets is bigger than the cost of moving the goods between them.

So start with a simple table. For each product, list the net price to the distributor in every market, then add freight, duties and handling to move it into your most expensive market. If the landed cost from your cheapest market is below your distributor price in your most expensive one, you have built a gray market yourself.

You do not need identical prices worldwide. You need gaps that are smaller than the cost and hassle of moving the goods. We explained how to build each market's price from the shelf backwards in our guide to export pricing and the margin stack. Run that exercise for every market at once, not one at a time.

Rule 2: Know what the law allows in each market

Before you threaten anyone, find out whether you can stop them. The answer depends on where you are.

• United States. Under the first sale doctrine, a genuine product you sold can generally be resold, and Kirtsaeng extended that to goods made abroad for copyright purposes. Brand owners have narrower tools: US Customs can restrict gray goods that are "materially different" from the US version under what is known as Lever-rule protection, which covers differences such as labeling, formulation or warranty.
• European Union. Inside the EU, once goods are sold in one member state, they can move freely to another. Since the Silhouette ruling of 1998, the EU applies regional exhaustion: you can usually block goods imported from outside the European Economic Area, but not goods moving between member states.
• Other markets apply their own rules, from international exhaustion to strict brand protection.

The single most expensive mistake in this area is trying to stop parallel trade inside the EU. On November 28, 2024, the European Commission fined Pierre Cardin and its licensee Ahlers €5.7 million for restricting cross-border sales of clothing. Brand owners can choose their distributors, but they cannot wall off member states from each other.

Rule 3: Write the territory rules into every contract

Most diversion starts with a distributor who buys more than its market needs, usually to hit a volume rebate, and sells the surplus to a trader.

Your distribution agreement should make that hard and visible:

• Define the territory and the customer types each distributor may serve, within what local competition law allows.
• Prohibit active selling outside the territory where the law permits, and be clear on what that means.
• Base rebates on sell-out, not sell-in. Paying a distributor for what reaches real customers removes the incentive to dump surplus stock on a broker.
• Reserve the right to audit sales records and to trace products back to the shipment.

Choosing the right partner in the first place matters even more. Our seven questions for choosing an international distributor include asking who else they sell to and how they handle surplus stock.

Rule 4: Make every unit traceable

You cannot enforce a contract if you cannot prove where a product came from.

Code every case and, ideally, every unit with something that tells you which shipment and which distributor it was sold to. That can be a lot number printed on the label, a serialized QR code, or an invisible mark that only your team can read. When a diverted product appears on a website or a shelf, you buy one, read the code and know exactly which partner leaked it.

Traceability also protects your customers. In food, beverages, cosmetics and electronics, a lot code lets you run a recall. The same system that fights diversion is the one regulators expect you to have anyway.

Rule 5: Make the official product better, not just more expensive

The strongest defense against gray goods is a customer who prefers the official version.

That means giving the authorized channel something the diverter cannot copy:

• Local labeling and compliance, which in many regulated categories is mandatory and is also the basis of the "material difference" argument.
• Warranty and service honored only for products bought through authorized dealers, stated clearly at the point of sale.
• Local formats, packs and assortments designed for each market.
• Support for the distributor's customers: training, marketing, fast replacement.

If the only difference between your official product and the gray one is the price, the gray one will win. Registering your trademark in each country you sell to strengthens every one of these defenses; we covered that in six trademark rules before entering a foreign market.

Rule 6: Monitor the market and act fast, but proportionately

Gray trade grows quietly. A few cases on a marketplace this quarter become a full container next year.

Set up a simple monitoring routine: someone checks the main online marketplaces and price comparison sites every month, and distributors report gray stock they see in their territory. When you find it:

1. Buy a sample and trace it to the leaking shipment.
2. Talk to the source distributor first. Many leaks are a sales rep chasing a target, not company policy.
3. Escalate in steps: warning, loss of rebates, reduced allocation, and only then termination.
4. Use legal action where the law clearly supports you, such as genuinely different products or trademark misuse, not as a reflex.

If a partner keeps leaking stock after warnings, it may be time to change distributors. Do it carefully; here is how to terminate a foreign distributor without creating a legal problem bigger than the one you are solving.

Key Takeaways

• Gray goods are genuine products sold through unauthorized routes. They are a pricing and channel problem before they are a legal one.
• Diversion happens when the price gap between markets exceeds the cost of moving goods. Manage the gaps across all markets at once.
• Know the law in each market. The US first sale doctrine and EU regional exhaustion limit what you can block, and restricting trade between EU member states can bring heavy fines.
• Contracts should reward sell-out, not sell-in, define territories and give you audit rights.
• Code every shipment so you can prove which partner leaked stock.
• Give the official channel real advantages: local labeling, warranty, service and support.
• Monitor monthly and escalate in proportion, starting with a conversation, not a lawsuit.

Frequently Asked Questions

What is a grey market importer?

A grey market importer is a trader who buys genuine branded goods outside the official distribution chain and resells them in another market without the brand owner's permission. The products are real, not counterfeit; only the route is unauthorized. They usually buy where the brand is cheap and sell where it is expensive.

What are parallel import goods?

Parallel imports are genuine products imported into a country outside the manufacturer's authorized distribution network. The term is often used interchangeably with gray market goods. They compete directly with the official importer, usually on price.

Is grey market legal or illegal?

It depends on the country and the product. In the United States, reselling genuine goods is generally legal under the first sale doctrine, although Customs can restrict versions that are materially different from the US product. In the EU, goods can move freely between member states, but brand owners can usually block imports from outside the European Economic Area.

Is it safe to buy parallel imports?

The product itself is usually genuine, but buyers can lose the local warranty, receive labeling or formulations meant for another country, or get goods that were stored poorly in transit. For businesses that resell, it can also mean losing access to manufacturer support and promotions.

How can a company stop product diversion?

Close the price gaps that make diversion profitable, base distributor rebates on real sell-out, code every shipment so leaks can be traced, and give the official channel advantages such as warranty and local labeling. Monitor marketplaces regularly and escalate with the source distributor before taking legal action.
