Costco Next Is Gone. The Korean Brand Playbook Needs Rewriting
Costco shut Costco Next in late August 2026 with no vendor notice. COSRX and Beauty of Joseon lost the channel. Every guide recommending it as a low-commitment entry point is now wrong, and Costco has announced no replacement.
If your US retail plan includes the sentence "start in Costco Next, prove velocity, then graduate to the warehouse floor," that plan no longer exists.
Costco shut down Costco Next in late August or early September 2026, abruptly and with no notice to vendors or members. The platform had been growing fast right up to the shutdown, by Costco's own account on its Q3 FY2025 earnings call. COSRX and Beauty of Joseon are among the named brands that lost the channel.
Costco has announced no replacement.
This matters more than a single channel closing, because Costco Next was doing quiet work that most brands did not notice.
What "sold at Costco" often actually meant
When a competitor's deck said "available at Costco," there was a decent chance it meant Costco Next: a vendor-fulfilled, consignment-like tier, not a warehouse floor listing with case pack compliance, pallet specs and audit requirements.
Those are materially different achievements. One is a marketplace listing. The other is winning a buyer meeting and surviving a velocity review.
So before you treat any competitor's Costco presence as a proven playbook, establish which tier it was. A good deal of what looked like K-beauty success at Costco ran through a channel that has now closed, and we could not verify whether specific K-beauty SKUs ever reached physical warehouse shelves at all as opposed to living entirely on Costco Next.
There is no online application
Costco's vendor inquiries page splits contact by category and offers no application portal:
- Food and sundry goes to the relevant regional division office
- Non-food goes to Issaquah headquarters
That is the whole published process. There is no form, no RangeMe equivalent, no submission queue. You are looking for a buyer introduction, a broker, or a roadshow.
The roadshow programme, run through Costco's Special Events organisation, remains the most accessible demonstration route. It is a temporary in-warehouse selling event, and for a food or beverage brand it functions as a live velocity test in front of the buyer who would place a permanent order.
The 14 percent rule and what it does to your cost stack
Costco's markup cap is real, old and well documented. Jim Sinegal's rule, quoted directly in 2005, was that no branded item is marked up more than 14 percent and no private label item more than 15 percent, against roughly 25 percent at supermarkets and 50 percent or more at department stores. Costco's average realised markup has been reported at about 11 percent, against roughly 24 percent at Walmart and 30 percent at supermarkets.
Most brands read this as good news. It is, for the shopper. For a supplier it inverts how you have to price.
At most retailers you start from your cost and work up. At Costco you start from the shelf price the buyer believes will move volume, and work down. Your FOB price, freight, duty and any importer margin all have to fit underneath that number with only 11 to 15 points left for Costco.
For a Korean brand this is where the 2026 tariff environment bites. A 15 percent duty on cosmetics that previously entered duty free has to be absorbed inside a stack that was already tighter than any other US channel.
Korean brands that are actually there
The confirmed Korean presence at Costco US is concentrated in food:
- bibigo (CJ CheilJedang), a chicken product in hundreds of stores as of November 2024, via CJ Schwan's
- Samyang, Buldak ramen, reported June 2026
- Nongshim, ramyun, listed directly on costco.com
We searched extensively in both English and Korean for a documented case of a Korean supplier moving from Costco Korea to Costco US and found none. The strong circumstantial evidence is that the two buying organisations operate independently, though we could not confirm this from a Costco statement.
The practical read: a strong Costco Korea record is a credibility signal for a first US pitch. It demonstrates scale, food safety audit history and sustained volume. It is not a warranted shortcut to a US buyer meeting, and treating it as one wastes the pitch.
Velocity, not listing fees, is the real risk
Costco carries roughly 3,700 to 4,000 SKUs company-wide. Compare that to the tens of thousands at a conventional supermarket.
That number explains Costco's behaviour better than anything else. Every slot is expensive in opportunity terms, so a product that pops on promotion and then fades gets delisted quickly. The threat is not an entry fee. It is that you win the shelf and then lose it in two quarters.
Which reframes what you should be preparing. Brands over-invest in getting the meeting and under-invest in proving they can hold a slot. Come with a plan for sustained velocity, not a launch spike.
We should note that several widely repeated Costco claims could not be traced to Costco itself, including specific case pack minimums, pallet and ISTA packaging specifications, chargeback percentages, and the frequently cited "no slotting fees." Those come from consultancies and software vendors. Get your actual requirements from the buyer or the division office, in writing.
What to do now that Next is closed
1. Remove Costco Next from any plan. If a consultant's deck still includes it, that deck predates September 2026.
2. Identify the right door. Food and sundry to the regional division office, non-food to Issaquah. There is no central queue.
3. Build the price from the shelf backwards, leaving 11 to 15 points for Costco, and check whether your landed cost under current tariffs still fits.
4. Treat a roadshow as the audition. For food and beverage it is the most realistic demonstration of velocity available to a new supplier.
5. Use Costco Korea as evidence, not as a referral. Bring the audit history and volume data, expect to pitch from zero.
6. Plan the second and third quarter, not the launch. A slot you cannot hold is worse than no slot, because it burns the relationship.
The closure of Costco Next removed the ramp. What is left is the front door, and the front door has always been narrow.
The Costco Next shutdown is reported from US business press coverage in September 2026. Markup figures are drawn from quoted statements by Costco leadership and subsequent reporting. Case pack, packaging and fee specifications cited by third parties could not be verified against Costco published material and should be confirmed directly.
