JD.com

JD.com is a major Chinese marketplace distinguished by its first-party model: it buys, stocks and ships a large share of what it sells rather than acting purely as an intermediary.

That gives it two advantages consumers value — authenticity, because the goods come through its own supply chain, and speed, because its logistics network reaches much of the country same-day or next-day.

Electronics and appliances are its strongest categories, historically the segment where counterfeit risk made a first-party guarantee most valuable.
