AliExpress Counterfeit / Brand Risk Warning

Quick answer

Paste an AliExpress listing that carries a brand name (Nike, Apple, Dyson…) and get a counterfeit-risk indicator: is the price far below the cheapest realistic

How the counterfeit-risk check works

price ratio = product price in USD ÷ cheapest realistic genuine price for the brand — under 20% ⇒ high risk, 20–50% ⇒ elevated, 50%+ ⇒ low

We read the product title from AliExpress's official partner API and scan it for 50+ well-known brands (whole-word matching, including aliases such as iPhone and AirPods for Apple). For each brand we store a "genuine floor": the lowest price a genuine item of that brand realistically sells for at official stores — a deliberately conservative number, set low so we never flag an innocent product. A price far below that floor is a strong counterfeit signal, because major brands are simply not sold at a third of their price. The strongest signal of all is the title itself containing words like Replica or 1:1 — that pushes the indicator straight to high risk. A "for iPhone" phrasing is treated as what it is: a legitimate way to describe compatible accessories, so no price-based judgement is made. The result is an estimated indicator plus a general customs warning for the shipping country you selected — not an accusation against the seller and not a legal judgement.

FAQs

How do you know a product is counterfeit?

We don't "know" — we estimate. Two signals drive it: first, the gap between the product's price (converted to USD) and the cheapest realistic genuine price for the same brand — e.g. a Dyson styler at $12 while the cheapest genuine Dyson product starts around $99, i.e. the price is only 12% of the floor. Second, words in the title itself that admit a copy (1:1, Replica, AAA quality). The more signals coincide, the stronger the indicator.

Do customs really seize counterfeit products?

Yes — this happens routinely and is well documented. Gulf customs detain IP-infringing goods including personal parcels; EU Regulation 608/2013 lets EU customs detain and destroy counterfeits in small consignments; US and UK customs seize them without compensation. Practically: if your parcel is seized you usually lose both its value and the shipping cost.

The product says "for iPhone" — does that mean it's fake?

Not necessarily. The "for / compatible with" phrasing (Case for iPhone) is the legitimate way third-party accessory makers describe compatibility, so we make no authenticity judgement from such an accessory's price. What we hunt for is the brand claimed on its own (e.g. AirPods) at an implausible price.

How accurate is this check?

It is an estimated indicator, not a lab test: we analyse only the title and the price, and never see the product or its photos. The price floors in our database are conservative estimates from official-store prices across 50+ brands. That is why we always show the reason behind each indicator with the exact numbers we derived it from, and state plainly that no brand match or a low indicator is not proof of authenticity.
