Founder, broker, and consultant reviewing an insurance certificate and contract for Costco vendor insurance requirements

Insurance is the least exciting part of becoming a Costco supplier and one of the most expensive to get wrong. The Costco vendor insurance requirements CPG brand 2026 conversation usually happens late: the buyer has said yes, the vendor agreement arrives, and the founder discovers a section about coverage that no one on the team has read closely. By then, the timeline is tight and the pressure to sign is high. This guide is meant to move that conversation earlier.

A critical note before anything else. We are a brand management firm, not an insurance broker or a law firm, and nothing here is insurance or legal advice. We could not find a published, Costco-specific schedule of required limits, and we are not going to invent one.

Your vendor agreement and your assigned Costco contacts are the source of truth, and your broker and attorney are the people who should interpret them. What this guide can do is help you know what to ask, why it matters, and how to avoid common traps.

Why Retailers Care So Much About Supplier Insurance

When a retailer sells your product, it becomes part of the chain of responsibility if something goes wrong. A contaminated item, a mislabeled allergen, a defective product, or a packaging failure can lead to claims against the retailer as well as the manufacturer. Retailers protect themselves in two ways: through the indemnity and contract terms in the vendor agreement, and by requiring suppliers to carry insurance that backs those promises.

In practice, that usually involves:

Commercial general liability (CGL) coverage, which commonly includes product liability.
Additional insured status, which gives the retailer certain rights under your policy.
Certificates of insurance (COIs), which prove the coverage exists.
Contract language about notice, renewal, and cancellation.

Large retailers across the industry, including other big-box and grocery chains, publish insurance requirements that specify minimum limits and endorsement language, often including primary and non-contributory wording. Costco’s specifics should come from your own agreement.

The Core Concepts, in Plain Language

Product liability coverage

Covers claims that your product caused bodily injury or property damage. For food, beverage, supplement, pet, and personal care brands, this is the central coverage.

Per-occurrence and aggregate limits

The per-occurrence limit is the most the policy pays for a single event. The aggregate is the maximum for the policy period. Retailers and distributors typically specify minimums for both, and for many suppliers the figures involve millions of dollars. Your agreement will tell you what applies to you.

Additional insured status

This endorsement lets the retailer be named on your policy for claims arising from your product. It is a common requirement and a frequent source of problems, because the wording of the endorsement matters.

Primary and non-contributory wording

This means your policy pays first and the retailer’s own insurance does not have to contribute. Some retailers insist on it.

Umbrella or excess coverage

Sits above the base policy to extend limits. Many brands use it to reach required totals economically.

Claims-made versus occurrence-based policies

An occurrence-based policy covers events that happen during the policy period, regardless of when the claim is filed.
A claims-made policy covers claims filed during the policy period, which can leave a gap if you cancel or change carriers unless you buy extended coverage, often called tail coverage.

Recall coverage

Separate from liability, this can help with the costs of a product recall. Retailers may ask about it, and for food brands it is worth discussing with your broker.

Why the Contract Ending Does Not Always End the Risk

A widely cited dispute involving Costco and the insurer Tokio Marine shows why the details matter. The case concerned tires supplied by Yokohama and a reported $5.5 million settlement. As described in reporting, the question that mattered was whether Costco’s additional insured status under the supplier’s policy still applied after the supply contract had ended, in a situation involving an occurrence-based general liability policy. The reported takeaway is that the retailer’s coverage as an additional insured depended on the policy language and the timing, and the status lapsed when the contract ended.

We describe this as a reported example, not as legal analysis. The lesson for brands is practical:

Product claims can surface long after a product is sold.
Your obligations and your coverage may not line up in time.
Policy wording, endorsement dates, and contract termination provisions interact in ways that are easy to miss.
A discontinued product can still produce claims, so ask your broker how your coverage handles products you no longer sell.

Questions to Ask Before You Sign

Bring these to your Costco contact, your broker, and your attorney:

What coverage types and minimum limits does our agreement require? Get it in writing and read the exact wording.
What endorsement language is required for additional insured status, and does our carrier offer it?
Is primary and non-contributory wording required?
What are the requirements for certificates of insurance, including who receives them and how often they must be updated?
What is the notice obligation if our coverage is canceled, changed, or not renewed?
How long must coverage continue after the supply relationship ends? This is where tail coverage or continuing occurrence coverage may matter.
Does our policy cover products manufactured by our co-packer, and does the co-packer carry its own coverage naming us?
Are there exclusions that affect our product, such as certain ingredients, claims, or manufacturing methods?
Do we need recall or contamination coverage, and what would it cost?
How do our limits compare with those required by other retail and distribution partners?

The Co-Packer Question

Many brands rely on contract manufacturers. Insurance then involves multiple parties. Ask:

Does the co-packer carry product liability coverage with adequate limits?
Are you named as an additional insured on the co-packer’s policy?
Who is responsible for a defect that originates in manufacturing versus a labeling or formulation error?
What do the manufacturing agreement’s indemnity provisions say?

Never assume that the co-packer’s coverage protects you. Verify it with documents.

Budgeting for Insurance

Insurance is a real cost of doing business with a large retailer. Costs depend on your category, sales volume, claims history, and required limits. Early-stage brands are sometimes surprised by premiums for higher limits. Include these in your financial model:

Base liability premium.
Umbrella or excess coverage.
Additional insured endorsement fees, if any.
Recall coverage, if purchased.
Broker fees.
Time spent on compliance paperwork.

Add these to your landed-cost and margin calculations before you finalize pricing. Thin margins can be eroded quickly by unplanned expenses.

Common Mistakes

Waiting until the vendor agreement arrives to talk to a broker.
Assuming a standard small-business policy meets retailer requirements.
Overlooking the endorsement wording and timing.
Letting coverage lapse during a renewal.
Not confirming the co-packer’s coverage.
Ignoring what happens after the contract ends.
Failing to track COI renewals and expirations.
Choosing the cheapest policy without checking exclusions.

Insurance is on the critical path. A policy upgrade or endorsement can take days or weeks, and a missing certificate can delay a first shipment.
