COUPANG KEYWORD REPORT
Selling carbonated soft drinks (탄산음료) on Coupang: competition, prices & top products
Direct answer
탄산음료 means "carbonated soft drinks" and carries an A demand grade on Coupang, with 40 organic listings competing in a ₩390–₩24,900 price band. The top 10 average 69,163 reviews — led by 나랑드사이다 제로 30-pack at ₩11,900 with 231,598 reviews and 칠성사이다 190ml 30-pack at ₩13,200 with 344,917 reviews — so review authority, not price, is the real barrier. Most winners are domestic brand multipacks in the ₩10,000–₩17,000 range, making this a very hard keyword for a new cross-border seller to enter head-on.

FAQ
Is 탄산음료 a realistic keyword for a new cross-border seller?
Not head-on. Demand is graded A and there are only 40 organic listings, but the top 10 average 69,163 reviews and the leaders sit above 200,000 — that review moat takes years to match. Enter through a niche variant (imported flavors, zero-sugar novelties) rather than mainstream soda.
What price should I target?
The observed band is ₩390–₩24,900. Most top sellers are multipacks priced roughly ₩10,810–₩17,140, so bundle economics matter more than unit price; the ₩390 entry (초록매실 스파클링 제로) shows single-unit or promo pricing also appears in results.
What formats win on this keyword?
Bulk multipacks dominate: 24- and 30-count cases in 190ml, 245ml, 345ml, 350ml, 355ml and 500ml sizes. Mixed variety sets also rank (e.g. the 6-type 24-pack at ₩23,580), which is a lower-review entry point with only 581 reviews on that listing.
