You invested in a market on the strength of a supplier's exclusivity promise — and the same product starts appearing under other flags. What Chinese law clearly gives the exclusive buyer, what remains genuinely contested, and how to draft and document so the promise holds.
Almost every serious distribution relationship starts with the same conversation. The buyer — investing in tooling, certification, marketing, a service network, inventory — asks the supplier for exclusivity: don't sell this product line in my territory, don't sell to my competitors, and I'll build your market. The supplier agrees, often warmly, in an email. What ends up in the signed contract is sometimes a clause, sometimes a single sentence in a PI, and sometimes nothing at all.
Then the diversion starts — often not flagrant, but structural: the "same" product reappears through a trading company, a sister factory in the same group quotes your customer directly, an online storefront undercutting your pricing ships from an address you recognize. The buyer asks the obvious question: is my exclusivity actually enforceable in China?
The honest answer has two parts, and they need to be kept apart. Part one is what Chinese law clearly establishes — and it is more than most buyers fear. Part two is what remains contested or fact-dependent — and it is more than most buyers expect. Both parts decide whether the promise is an asset or expensive paper.
Drafting against a clause is easier when you understand the behavior it is meant to stop. Diversion is rarely irrational; it is the predictable result of what happens after the buyer builds the market. Your certification, your marketing, your service network create demand that other players would like to serve — and from the supplier's side, a second or third buyer for the same product line in your territory is incremental revenue at almost no acquisition cost. You paid for the market entry; they ride it. Competition for the market's rents, in other words, not malice, is the default state — and the exclusivity clause is the mechanism that prices it.
The standard plays, in rising order of sophistication. The direct one: quiet sales to a trading company that on-sells into your territory. The structural one: sales through a sister factory or affiliated exporter in the same group, so the contracting entity's hands stay formally clean. The channel one: the product appears on e-commerce platforms, sometimes under a slightly different listing, sometimes gray-labeled. And the pricing one: no diversion at all, but margin erosion — the supplier quietly supplying a price-war competitor while honoring the letter of the exclusivity and destroying its economics. Each play defeats a differently drafted clause, which is why the scope definition has to be written with these patterns on the desk, not from a form book.
Start with the bedrock. Under Chinese law, an exclusivity undertaking between a supplier and its buyer is, at its core, an ordinary contractual term — and it is valid. The general principles of contract freedom under the Civil Code support agreements under which a supplier binds itself to sell a defined product only to a defined buyer, or not to supply a defined territory or defined competitors. This is a mainstream commercial arrangement in China, used constantly in domestic distribution; a foreign buyer's exclusive-supply clause does not sit in some exotic legal category.
Three consequences follow, all of them solid:
So the starting position is favorable: you are not holding a void promise. One taxonomy note before moving on, because buyers often lump distinct animals together. A sole-supply undertaking (the supplier sells this line to you alone in a defined scope) is the core case. A right of first refusal (the supplier must offer you the chance to match before selling elsewhere) is a different, weaker animal with different mechanics. A buyer-side non-compete (you won't carry competing brands) binds you, not them — and suppliers frequently ask for it in the same breath as giving exclusivity, which is exactly when both should be priced together. Each is valid as a contract term; each fails differently when drafted loosely.
The difficulty begins where everyone's case actually lives — in the boundaries around the promise, and in the proof of its breach.
Here the honest framing matters, because each of the following points is genuinely unsettled at the level of "it depends."
The competition-law boundary of territorial exclusivity. Chinese competition law distinguishes between agreements that are flatly prohibited — notably, fixing minimum resale prices — and other vertical restraints, including territorial and customer restrictions, which are assessed with room for the parties to show the arrangement does not have the effect of eliminating or restricting competition. For the typical foreign buyer negotiating with its own supplier, this is usually a theoretical risk: the buyer is the beneficiary of the restriction and rarely holds market power. But it is not zero — a exclusivity scheme with wide market coverage, long duration, or market-power dynamics can attract scrutiny, and the analysis depends on market definition, market shares, and effects, none of which can be resolved in a blog post. Practical guidance: exclusivity scoped to what the buyer genuinely invests in — a defined product line, a defined territory or channel — is both more defensible and more enforceable than sprawling, open-ended restraints. If your arrangement has real breadth or duration, get an actual competition-law opinion rather than a blog's assurance.
Specific performance of a continuing supply obligation. Suppose the court finds the breach: can it order the supplier to keep supplying you exclusively for the next three years? As a practical matter, Chinese courts are reluctant to supervise ongoing positive obligations of that kind, and the realistic outcome in most cases is damages for past breaches plus the buyer's right to terminate — not an injunction forcing future supply. This is a matter of judicial practice and the facts of each case rather than a bright-line rule, but buyers should plan for it: the exclusive supplier who wants out can usually buy out, and the contract should be priced for that possibility.
Enforceability is a function of precision and evidence. "The Supplier shall support the Buyer's market development" is not an exclusivity clause; it is a mood. Whether the promise is enforceable — against whom, for what, in which territory, for which products — turns entirely on how precisely the scope was written and how well the bargain was documented. That is a drafting problem, and it is solvable.
Exclusivity cases are won and lost on two evidence sets: the bargain, and the breach.
Fix the bargain while everyone is friends. The exclusivity agreement — including the email chain that preceded it, the PI terms, meeting minutes — should exist in a signed, bilingual form with the supplier's company chop, from the signing entity. A warm email from "the sales manager of the factory" is a fragile basis for a restraint claim; a stamped exclusivity annex is not. If the exclusivity was agreed in correspondence, memorialize it: a short confirmation document, chopped and returned, costs one email and years of argument.
Fix the breach like a litigator, not like a victim. When diverted product appears: buy it — through a third party, with payment records and delivery documentation, and where the stakes justify it, through notarized purchase procedures that preserve the evidence chain; screenshot listings with timestamps and store-entity details before they vanish; record container numbers, shipping-route clues, and factory addresses where visible; and preserve every communication in which anyone — the supplier's staff, the trader, the affiliated factory — acknowledges the source of the goods. Commercial trade-data services can help identify exporter patterns for a product line, but treat such data as an investigative lead rather than courtroom proof, and let the notarized purchase do the evidentiary work. Diversion through affiliated entities is standard practice, so build the paper trail that connects the goods to the group, not just to the flag they sailed under.
Keep the loss file in parallel. Your own sales records for the exclusive territory, margin data, the investment made in reliance — maintained contemporaneously, not reconstructed. When the claim is finally quantified, the buyer who can hand over a clean file negotiates from a different planet than the buyer who starts digging after the demand letter.
| Element | Standard to meet |
|---|---|
| Scope definition | Products (SKU annex), territory, channels, protected customers — all named, all bounded |
| Bound parties | Supplier plus group companies and affiliates, each named or structurally captured |
| Consideration | Minimum purchases or equivalent commitment from the buyer, stated in the same document |
| Remedy structure | Liquidated damages per breach event + termination + investment protection on supplier-caused exit |
| Documentation | Bilingual, chopped by the signing entity; the pre-contract email chain preserved |
| Breach evidence | Test purchases (notarized where warranted), timestamped listings, entity-linkage trail, contemporaneous loss records |
An exclusivity promise in China is neither magic nor waste paper. It is a contract term whose value scales with the precision of its scope, the care of its documentation, and the discipline of your evidence file — the same three variables that decide most things in this trade. Building an exclusivity annex and its evidence architecture is standard work in a contract and trade document review; doing it before the market investment, not after the first diverted container, is the whole trick.
This article is general information, not legal advice, and does not create an attorney–client relationship. The competition-law treatment of any specific exclusivity arrangement depends on its facts and market context; obtain a case-specific opinion before relying on any restraint. Outcomes vary; nothing here is a guarantee of results.
