What Is a Counterfeit Product Dispute? Quick Answer & Key Definitions

TL;DR for Buyers: File a platform dispute immediately with photos, receipts, and authenticity proof--aim for 90%+ refund success within 14-60 days (e.g., Amazon A-to-z Guarantee, AliExpress 15-day post-delivery window).
TL;DR for Sellers: Respond within 48 hours to claims with invoices, supplier certifications, and authenticity tests to lift listings and avoid account suspension.

A counterfeit product dispute arises when a buyer claims an item is fake (imitating a trademarked brand without authorization) or a brand/seller is accused of infringement. Counterfeits are unauthorized replicas, often sold as authentic, harming brands and consumers. "Superfakes" complicate this--high-quality fakes mimicking originals, challenging traditional "shoddy imitation" claims (The Fashion Law, 2025).

Stats highlight the scale: US Customs & Border Protection (CBP) seized 26,500 counterfeit shipments in 2020 worth $1.3B. France ramped up to 11M items seized in 2022 (up from 5.6M in 2020), with Nice alone destroying 170K in 2021--a 170% jump. Global counterfeits hit $1.7-4.5T annually.
