Detection guide
Grey-market goods are genuine — made by you, in your packaging — but sold through a channel you never authorized: diverted across borders, leaked from a distributor, or resurfaced from a liquidation lot. Because the product is real, grey market is a supply-chain investigation wearing a marketplace costume: the listing is the symptom, the diversion source is the problem.
This guide covers the diversion patterns that put genuine goods on the wrong shelves, why binary authorized/unauthorized checks miss half the category, and the explicit territory-and-channel rules Pricelysis classifies listings against.
Grey market arrives through a handful of well-worn routes:
Note what these have in common: many involve sellers you know. A binary "is this seller authorized?" check calls a dealer selling outside their territory clean — which is exactly wrong.
"Unauthorized seller" isn't a precise enough question. A large share of grey-market activity comes from parties inside your network — authorized dealers selling outside their licensed territory, or on channels their agreement doesn't cover. Tools with a flat allow-list wave those listings through.
The product itself gives nothing away online. A photo of a genuine diverted unit is a photo of a genuine unit; you can't see batch codes, packaging language, or warranty cards in a listing. Pure image- or text-matching approaches have no signal to work with.
And volume defeats manual triage: flag every discounted listing as potential diversion and the team drowns. A working program needs rules tied to your actual distribution agreements.
Pricelysis classifies every discovered listing against your authorized-dealer records with explicit, deterministic rules — not a similarity score.
Each listing is resolved to its source domain and matched against the dealers you've registered. No match at all produces an unauthorized-seller finding: someone entirely outside your network.
The dealer matches, but the listing is outside the territory their agreement licenses — the cross-border diversion case, caught even though the seller is "authorized" in the flat-list sense.
The dealer matches, but the marketplace isn't a channel they're licensed for — the brick-and-mortar dealer selling on Amazon case.
Each alert lists exactly which rule fired, plus the seller, listing URL, and price. And because the rules read from your safe list, updating a dealer's territory or channels reclassifies their listings immediately — no retraining, no support ticket.
Enforcement stays human-approved. A territory breach by a real dealer is a contract conversation backed by evidence — not an automated takedown that torches the relationship.
Grey-market enforcement runs on two tracks — marketplace complaints and distribution-agreement enforcement — and each needs its own evidence:
Batch-code tracing is the highest-leverage artifact: one traced unit can close the source that feeds fifty listings.
Trace sources before chasing listings. Recurring diversion from one distributor beats serial takedowns — close the leak and the listings starve. Short-dated stock jumps the queue because it converts directly into safety exposure and review damage.
Handle in-network breaches (wrong territory, wrong channel) through the agreement, with a cure window; reserve marketplace complaints for out-of-network diverters where material differences are documented.
Usually not by itself — genuine goods can generally be resold under the first sale doctrine and its analogues. Enforcement leans on two levers: contract (your distribution agreements) and the material-differences doctrine, which lets trademark holders challenge resale of genuine goods that materially differ from authorized versions. Consult counsel for contested matters.
Grey-market goods are real; counterfeits are fake at manufacture. Filing a counterfeit complaint against goods that turn out to be genuine diverted stock damages your credibility with the platform — verify with a test purchase before choosing the enforcement path.
Test purchases. Batch codes, lot numbers, packaging language, and regulatory marks narrow a unit to a production run and often to a distributor allocation. One confirmed trace is usually enough to start the contract conversation.
Not for being grey market as such — marketplaces don't enforce your distribution agreements. Complaints succeed when framed on what platforms do police: material differences from the authorized product, condition misrepresentation ("new" goods that are short-dated), or safety issues.
That's the most common case — and the reason enforcement is human-approved. The evidence pack supports a notice under the agreement's territory or channel clause with a cure window. Most dealers stop when shown the trace; the ones who don't have told you something important.
Short-dated stock, missing warranties, wrong-region formulations, and no local support all generate returns and one-star reviews that land on your listings — and grey-market pricing undercuts the authorized retailers who fund your growth.
