Is your recipe ready for a co-packer?

The ten things plants ask about

University and industry guides give founders the same advice: prepare before you meet a co-packer. UF/IFAS lists a business plan and detailed process instructions, with specifications for ingredients, packaging and labeling¹. A co-packer search checklist adds a product specification sheet, a commercial formula, packaging specifications, a process flowchart and volume projections². In practice, plants ask about these ten things:

1. Your recipe is manufacturing-ready: a formula by weight, ingredients you can buy in bulk, and a test at a larger batch size. See a formula, not a recipe.
2. You know how the product is preserved: shelf stable or refrigerated, and whether it is an acidified or low-acid food that needs a process authority. Read Low-acid canned foods and acidified foods.
3. You have chosen the container, closure and label, and you know where to buy them. See packaging.
4. You know your first-run size and a rough 12-month volume. Read Co-packer minimum order quantities by category.
5. You know who buys the ingredients and packaging: the plant (turnkey) or you (tolling). Read tolling vs turnkey.
6. Your label is ready or in progress: nutrition facts, ingredients and allergens, and a barcode. See the label.
7. You know which certifications your buyers require, such as organic, kosher, gluten-free or SQF. See certifications.
8. You know where finished goods go after the run and how they ship. See after the run.
9. You have a budget for the first run: setup, ingredients, packaging and testing. Read What it costs to launch with a co-packer.
10. You have product liability insurance or a plan to get it. Read insurance limits.

A formula, not a recipe

A plant quotes from a formula, not from cups and spoonfuls. Molly Mills Creative, a sister company of Co-Packer Match, describes what a production-ready recipe package holds³:

• A master formula with every ingredient as a percentage of total batch weight. It scales to any batch size, and it is the format co-packers, regulatory consultants and process authorities expect³.
• A specification for each ingredient: the brand, grade and form you buy, and the substitutes you approve. Her example is vinegar: if you need 100-grain and the plant buys 50-grain, the acidity of your product halves³.
• A manufacturing procedure written in numbers: the order ingredients go in, target temperatures, hold times and the checks at each step³.
• Quality targets such as pH, Brix, viscosity, water activity and fill weight, each with an acceptable range³.

Every ingredient also has to be one you can buy in bulk, to the same specification every time. If part of your recipe only comes from a grocery shelf, find the bulk version before the plant does, and taste the difference.

Then test it bigger. Multiplying a kitchen recipe rarely works, because heat, evaporation and how much flavor the spices release all change in a large kettle⁴. A pilot batch, run in the plant on its equipment and with your packaging, proves the recipe before you pay for a full run⁵.

Packaging

Plants run particular containers, so ask each one which container sizes and closures its line can run¹. The container also has to suit the process: hot-fill containers are made to withstand the heat and the vacuum that forms as the product cools⁶.

Settle the packaging before you budget the run. The plant files a scheduled process for each acidified food in each container size, so a new size means a new filing⁷. Shelf-life studies work best with the real market packaging⁸, and printed packaging is often paid for in full up front⁹.

Who buys it depends on the deal. Under tolling you supply some or all of the ingredients and packaging¹⁰; a turnkey plant buys them for you. Either way, ask the plant which packaging suppliers it already works with.

Closures and labels fail quietly. A cap applied too loosely on a hot-filled product can leave a weak vacuum, and some label adhesives slide off after cold storage. Molly Mills Creative's packaging guide walks through these failures and how to test for them¹¹.

The label

FDA's Food Labeling Guide sets out what goes where. The front of the package, the principal display panel, carries the name of the food and the net quantity. The information panel carries the name and address of the manufacturer, packer or distributor, the ingredient list, nutrition labeling and any required allergen labeling¹².

• Ingredients are listed by their common name, heaviest first¹².
• Net quantity appears in both metric and US units¹².
• When a co-packer makes your product and your company's name is on the label, the name needs a phrase that shows how you relate to the product, such as manufactured for or distributed by¹².
• Major food allergens must be declared. Sesame became the ninth major food allergen under the FASTER Act¹³.
• FDA has a small business exemption from nutrition labeling. It covers a product when the business has fewer than 100 full-time equivalent employees and sells fewer than 100,000 units of that product in the United States in 12 months. The business files a notice with FDA each year, and a product that makes a nutrition claim does not qualify¹⁴. Businesses with fewer than 10 full-time equivalent employees selling fewer than 10,000 units do not have to file¹².
• A nutrition panel can come from a lab test or a database calculation. Molly Mills Creative puts a standard lab panel at about $700 to $2,500 and a database calculation at about $200 to $800¹⁵.
• A barcode is a retailer's requirement, not FDA's: FDA's guide notes that the UPC bar code is not FDA-required labeling¹². GS1 US issues them, and each variation of each product, such as each size or flavor, needs its own. When we checked, a single GS1 US barcode cost $30, and a company prefix for 10 items cost $250 plus $50 a year¹⁶.

Products with meat or poultry under USDA inspection follow USDA's label rules instead. See FDA or USDA: when meat or poultry changes the rules.

Certifications your buyers ask for

Find out which certificates your buyers want before you shortlist plants, because for some of them the plant has to be certified too.

• Organic: every operation that produces or handles a product sold as organic must be certified, unless it is exempt¹⁷. If a co-packer makes your organic product, its facility generally needs to be a certified organic handler for the run¹⁸.
• Gluten-free: FDA lets a food be labeled gluten-free when any unavoidable gluten in it is below 20 parts per million¹⁹. A third-party gluten-free seal is a separate, voluntary certification, often with a stricter limit, audits and testing¹⁸.
• Kosher: ask the plant which agency certifies it and whether your product can run under that certificate.
• Food safety: many large retailers ask for a certificate from a GFSI-recognized program such as SQF or BRCGS. Read GFSI, SQF, BRCGS and FSSC 22000 explained.

After the run: storage and shipping

Finished goods need somewhere to go the day the run ends: your own space, the plant's warehouse, a third-party warehouse or a distributor. Plan it before you book the run.

• Storage at a co-packer is often charged per pallet per month. One 2026 pricing guide puts it at $20 to $25, with some plants still at $12 to $20²⁰.
• Ask who owns the materials and the finished goods at each step⁹, and list warehousing, freight and pallets in the agreement as pass-through costs²¹.
• A broker sells your product to retail buyers, a distributor buys it, stores it and ships it to stores, and direct store delivery puts it on the shelf. None of them creates demand for you²².
• Case size and pallet pattern set the freight class of every less-than-truckload shipment, so settle them along with your packaging²³.
• Retailers often pay on Net 60 to 120 terms⁹, so the cash a first run ties up stays tied up after it ships.
