Costco Vendor Requirements: What CPG Brands Need to Know Before They Apply
Costco isn't just another retail account. A typical grocery store carries 30,000 to 40,000 SKUs. Costco carries roughly 3,500 to 4,000 items per warehouse. That means if your product gets in, you're one of a very small group. And if it doesn't move, you're out. There's no soft landing.
What makes Costco genuinely exciting for a growth-stage brand isn't just the volume potential. It's the signal. Getting stocked at Costco tells the market you have a product that performs and an operation that can support it. But brands that show up with a great product and an unprepared operation learn quickly that Costco will expose every crack in your supply chain. Fast.
Before you contact a buyer, submit samples, or even look up the Costco vendor inquiry portal, here's what you actually need to have dialed in.
Financial and Business Readiness
Costco buyers don't work with startups. They work with brands that have already demonstrated market traction. You'll generally want at least $500,000 in existing sales before you approach a buyer, and that number is a floor, not a target. More important is where those sales come from. Existing retail presence, especially in grocery or specialty food, signals that your supply chain can handle reorder cycles and that your product has already earned shelf space somewhere.
One thing brands consistently underestimate: Costco shouldn't represent more than 20% of your total business. It sounds counterintuitive to cap your upside, but this is about survival. If Costco drops you or changes the format, and it does happen, you need to still have a company left. Manage the concentration risk early.
How to Become a Costco Vendor
Costco is organized into regional divisions, including Bay Area, Los Angeles, Midwest, Southeast, and others. You don't have to go national on day one, and honestly, you shouldn't try to. A regional rollout lets you prove velocity, fix operational issues, and scale at a pace your manufacturing partners can actually support.
The first step is reaching out through Costco's Vendor Inquiry portal or, better yet, connecting directly with a category buyer. Costco buyers are not passive reviewers of inbound applications. They actively recruit vendors based on strategic fit for their category. That means your pitch needs to be tight, your product needs to be differentiated, and your price point needs to make sense in a club-pack format.
Once there's interest, you'll likely be asked to submit product samples and make a presentation. A full vendor/supplier application goes to a regional manager who works with the category buyer. Don't rush this stage. A sloppy application or a product that doesn't hold up on the floor sends a signal you don't want to send.
For smaller brands that aren't quite ready for full vendor status, Costco Roadshows (also called Special Events) are worth exploring. They're a lower-barrier entry point that lets you test product velocity in a Costco environment before committing to the full operational build-out.
Food Safety Audit Requirements
If you're in food or beverage, this is where brands get tripped up most often. Costco has real, non-negotiable food safety requirements, and they audit for them.
You have two paths: a proprietary Costco GMP Food Safety Audit, or a GFSI-recognized certification (BRCGS, FSSC 22000, or SQF) paired with a Costco-specific Addendum. BRCGS requires Grade B or higher; SQF requires 85% or above. Most audits must be unannounced, with the exception of the Costco Small Supplier audit program.
You'll also need a written Food Safety Plan with a detailed HACCP or Preventive Controls risk assessment. Traceability is equally important: Costco requires that you can trace specific lots one step forward and one step back within two hours. If you're running on spreadsheets and tribal knowledge, that's a problem you need to solve before you apply.
One more detail that trips people up: Julian code dating on your products is not acceptable. All products must carry a use-by, sell-by, or best-before date in a standard consumer-readable format. And if you're producing out of a shared kitchen, know that Costco requires a commercial-grade, dedicated facility. Reach out to your buyer before you schedule an audit so you're not doing it out of sequence.
Packaging Requirements
Club-pack format is its own discipline. Costco products aren't shelved; they're merchandised on pallets on a warehouse floor. That changes everything about how you think about packaging, from structural specs to how your graphics communicate at floor level.
On the structural side: pallet footprint should not exceed 48 by 40 inches (47 by 39 is the recommended target). Maximum pallet height is 58 inches including the pallet itself, and maximum load weight is 2,500 lbs. Your unit load needs to maximize pallet area with no gaps between sell units or master cartons. And packaging must be engineered to withstand significant clamp truck pressure during distribution — Costco's structural specs define the exact tolerances, and your co-packer needs to know them.
Pallets must be iGPS, PECO, or CHEP U.S. Block. GMA stringer and CHEP Canada stringer pallets aren't accepted. If you're not sure which pallet type your co-packer is using, check now.
From a display standpoint, Costco warehouse staff should be able to cut shrink wrap and drop the pallet directly to the floor without needing box cutters or restocking labor. Packaging needs to be display-ready out of the box.
On sustainability: Costco expects recyclable materials, FSC-certified paper, and soy-based inks where possible. Avoid EPS foam unless you have explicit buyer approval. These aren't just preferences; they're part of the brand alignment they expect from suppliers.
If your current co-packer doesn't have experience with Costco pallet specs, find one that does before you get too far down the road. The format requirements are detailed and the tolerances are tight.

EDI and Logistics Compliance
This is the area where growing brands most often take chargebacks they didn't see coming. Costco requires full EDI compliance: purchase orders (850), advance ship notices (856), invoices (810), and acknowledgments (997). All new suppliers are onboarded through SPS Commerce, Costco's required EDI onboarding provider.
The detail that matters most: your ASN (Advance Ship Notice) must be transmitted before your shipment arrives, not after. Costco's warehouse systems rely on ASNs for receiving. If it's late or incorrect, it doesn't just create a delay at that warehouse. Costco runs a cross-dock model where inbound product moves to the club floor within 24 to 48 hours, so a compliance error creates ripple effects across multiple locations fast.
Every pallet and carton needs a GS1-128 label that includes an SSCC-18 barcode, PO number, item information, and carton count. Mislabeled or unreadable barcodes result in chargebacks that add up quickly. This isn't punitive; it's how Costco protects the accuracy of its receiving operation. Build your labeling process correctly from the start and you won't be in a position to learn this lesson the hard way.
From a supply chain readiness standpoint, Costco orders spike. Plan for it. Align your production schedule, co-packer capacity, and inventory positioning before your first PO, not after it arrives.
Insurance Requirements
Costco's insurance requirements are significant and worth reviewing with your broker early. Vendors must carry Commercial General Liability Insurance with a minimum of $5,000,000 per occurrence, and both General Aggregate and Products and Completed Operations Aggregate limits must match that $5,000,000 floor.
If your employees will be on Costco premises, you'll also need Workers' Compensation and Employers' Liability Insurance at $1,000,000 per accident, plus Automobile Liability Insurance at $1,000,000 per accident. Don't assume your current policy covers these thresholds. Many growth-stage brands are carrying policies that were appropriate at $2M in revenue but don't meet these requirements. Get this sorted before the buyer asks for your certificate.
Other Costco Supplier Requirements
A few other things worth knowing as you build your readiness checklist.
Costco has a strict policy against human trafficking and modern slavery. Brands may be audited for compliance as part of the application process. If you work with contract manufacturers, especially internationally, make sure your supply chain documentation is clean.
On pricing: Costco operates on a margin structure of roughly 14% or less. That's not a negotiating position; it's a structural constraint. Your product needs to be priced so the value proposition works within that model for both you and Costco. If your current price point doesn't have room for club-pack economics, that's something to solve before you pitch.
Keep your SKU count tight. Costco wants fast-selling formats, not product line presentations. Lead with your best performer in a club-appropriate size or multi-pack. Leave the full catalog at home.
And finally, Costco actively promotes supplier diversity. If your brand is small or diverse-owned, that's worth noting in your application. It's a genuine consideration in how they build their supplier base.

Frequently Asked Questions
What are the basic Costco vendor requirements?
To sell at Costco, brands need to meet requirements across food safety (GFSI certification or Costco GMP audit), packaging (club-pack format, pallet specs), EDI compliance (via SPS Commerce), and insurance ($5M CGL minimum). Financial readiness matters too: most accepted vendors have at least $500,000 in existing sales and a demonstrated retail track record.
How do I become a Costco vendor?
Start by submitting an inquiry through Costco's Vendor Inquiry portal or connecting directly with a category buyer in your relevant regional division. Costco buyers proactively recruit suppliers based on category fit, so it helps to approach the relationship strategically rather than treating it like a passive application process.
How long does it take to get approved as a Costco supplier?
The timeline varies by category and buyer, but brands should plan for a process that spans several months from initial contact to first purchase order. Food safety audits, packaging development, EDI setup, and internal approval processes all take time. Brands that start the operational readiness work early will be better positioned to move quickly when a buyer is ready.
Do I have to sell nationally to become a Costco vendor?
No. Costco is organized into regional divisions, and brands can launch in one region first. A regional launch lets you prove product velocity, work out operational issues, and scale at a pace your manufacturing partners can support before expanding to additional divisions.
What EDI system does Costco use?
Costco requires all new suppliers to onboard through SPS Commerce for EDI compliance. Required transaction sets include 850 (purchase orders), 856 (advance ship notices), 810 (invoices), and 997 (acknowledgments). Your ASN must be transmitted before the shipment arrives at Costco's facility.
