Clean Label Requirements by Retailer: Whole Foods, Kroger, Costco, Walmart

You are prepping a product review for Whole Foods, Kroger, or HEB and each one hands you a different banned ingredient list. One wants no BHT/BHA. Another demands non-GMO Project Verified. A third rejects any natural flavor with residual solvent. Reformulating blind costs months. Here is what each major retailer is actually asking for in 2026, before you submit the spec.

Whole Foods Market. A Published Banned List

Whole Foods Market publishes a list of more than 300 ingredients it bans from the food it sells. It notes the list is written for shoppers and does not include every supplier requirement. For meat and prepared foods suppliers, key banned ingredients include:

• Sodium tripolyphosphate and all phosphates
• Sodium nitrite and nitrate
• All artificial colors including Red 40 and Yellow 5
• Artificial flavors
• Carrageenan, BHA/BHT, and high fructose corn syrup

Ask the buyer for the current supplier requirements before you formulate. Products must also meet their animal welfare standards (GAP-rated for meat). Plan for a review that can take months, so start before your reset date. If your retailer has already asked you to remove specific dyes, see our full playbook for removing Red 40.

Kroger. Simple Truth and Private Label Standards

Simple Truth is Kroger's natural private label line. Ask the buyer for the current Simple Truth standard and the conventional Kroger brand standard; they are not the same list.

Costco. Kirkland Signature Requirements

While Costco doesn't publish a formal banned ingredients list like Whole Foods, their buyer requirements include: preference for recognizable, simple ingredients, growing restrictions on phosphates in meat products, no artificial colors in most categories, and strong preference for products that can be marketed as "natural" or "clean label." We have not found a published banned ingredients list for Kirkland Signature. Ask the buyer which ingredients the category excludes before the pitch.

Walmart. Great Value and Scale Requirements

Walmart's approach is different. They focus less on strict banned ingredient lists and more on cost-per-unit optimization. Walmart announced it will remove 11 synthetic dyes and more than 30 other ingredients from its US private brand foods, including Great Value, by January 2027.

Hispanic Supermarket Chains. The Emerging Opportunity

Regional Hispanic supermarket chains are rapidly professionalizing their prepared foods operations. While they don't have formal clean-label programs like the national chains, they face the same consumer pressure. These chains are moving from scratch kitchens to standardized prepared foods programs. What they ask of suppliers is consistency: the same pastor, birria, carnitas in every store, with ingredients a shopper recognizes. See how Hispanic supermarkets are scaling prepared foods.

How to Prepare for Any Retailer

Regardless of which retailer you're targeting, the playbook is the same:

1. Audit your current formulations against the strictest standard (Whole Foods)
2. Identify ingredients that need to be replaced (phosphates, nitrites, artificial colors, artificial flavors)
3. Develop clean-label alternatives that maintain product performance
4. Get samples and technical documentation ready before the buyer meeting

Step 3 is where most projects stall. Pulling an ingredient is simple. Holding flavor, color and adhesion once it is gone takes formulation work. If you would rather buy the finished blend than build it, see clean label seasoning systems for manufacturers.

With the FDA's Red Dye No. 3 revocation in effect and a voluntary federal phase-out of six more synthetic dyes underway, aligning to the strictest clean-label standard now saves you from reformulating twice.

Imported brands face the same retailer ingredient standards, only earlier in the process, before a first US listing exists. That is the work we do on ourUS distribution program for international food brands. For the full list of failure points, see why US retailers reject imported food products.
