Advertising system na Coupang Ads (search/display ads, pay per click). Rocket Growth sellers get traffic weighting through rocket warehouse; big sales (Mega Sale etc) traffic dey highly concentrated.

Fulfilment & logistics

Self-built last-mile delivery network + cold chain (Rocket Fresh): same-day delivery for Seoul etc core areas, next-day for most of country — na di most complete next-day infrastructure for Korea (kr_platforms.md 6.2.1). Seller side fit enter Coupang Fulfillment Services. Global sellers use CGF official rocket warehouse (Chinese sellers send goods to fulfilment center, Coupang finish cross-border + Korea last-mile) or self-ship direct mail (no tracking: overseas items auto-confirm receive on day 45, delivery slow, Chuhai 2025.2).

Payments & settlement

Buyer side support Coupang Pay, credit card, account transfer etc, settlement currency won. Long settlement cycle na recognized pain point: Korea Large-Scale Distribution Industry Act allow big distributors up to 60 days settlement; Coupang almost use up di limit — KBS report Naver/Gmarket 1 day, 11st 2 days settlement, Coupang near 60 days (KBS 2025.12.24). From 2024 launch paid quick-settlement service (basic rate 0.31%, pay more fit get faster, KBS). SME Central Association survey 34% respondents say money-back over 51 days (DigitalToday). Chinese material say local shops weekly/biweekly, cross-border shops monthly settlement (Chuhai 2025.2, coexist with KBS, as e dey for contract). Cross-border sellers fit bind PingPong/Payoneer etc third-party collection (withdrawal fee about 1%).

Compliance

Korea Personal Information Protection Act (PIPA/PIPC) regulate very strict: 2025.11 data breach hit 33.7 million Korea users, initial compensation plan about $1.1B (about ₩1.5T-level coupons), worst-case estimate $11.4B; government cross-department review, lawmakers dey brew stronger penalties (kr_platforms.md; Insideretail/Korea Times). Product compliance: electrical appliances, children products, batteries, food, cosmetics, medical-related need KC etc certification, some KC certification only Korea entity fit apply. Korea grid na 220V/60Hz, plug-in products must check voltage an certification (52by). Open-market fake-goods governance an search ranking rules dey under continuous KFTC regulation (2025 KFTC once investigate/penalize membership bundling an quick settlement, BusinessKorea/KBS).

Key risks
