How to Write a Formula and Packaging Brief a Manufacturer Can Act On
Delays between a brand and its manufacturer rarely come from a missing field alone. More often they come from an assumption nobody wrote down. This guide treats the brief as a decision document: what is fixed, what is open, who decides each point, and what happens when it is missing.
A brief is a decision document
A brief is often treated as a form to fill in. It works better as a record of decisions: what the brand has already decided, what it leaves to the manufacturer's expertise, and what is still undecided. A manufacturer can work with open points. What slows a project down is an open point presented as decided, or a decision nobody wrote down.
Our view is that most back-and-forth between a brand and its manufacturer starts with an unstated assumption rather than a missing field. The method below is built to surface those assumptions before the first sample.
Three statuses for every field
- Fixed: decided by the brand and not open to discussion without a new decision. Example: the target markets.
- Open: left to the manufacturer's proposal, within stated limits. Example: the preservative system, within the rules of the target markets.
- To be decided: neither party can fix it yet, so the brief names who will decide and by when. Example: the final pack, while two options are still being costed.
Marking each field this way changes the conversation. The manufacturer knows where it can propose, where it must comply, and which questions are already expected.
The fields a manufacturer needs
The table groups the fields that most often decide whether a lab can formulate and quote. For each one, it states who usually decides and what tends to happen when the field is missing. It is our working list, not an industry standard: adapt it to your category.
Formula and packaging brief: fields, owners and consequences
| Field | Who usually decides | If it is missing |
|---|---|---|
| Product and use: format, application, frequency, user | Brand | The lab formulates for its own idea of the use, and the first sample misses. |
| Target markets and channels | Brand | Regulatory checks, ingredient choices and labelling are redone when a market is added late. |
| Claims, with the level of evidence expected | Brand, with the manufacturer on feasibility | Tests are planned late or not at all, and claims are cut before launch. |
| Sensory targets: texture, scent, colour, finish, with references | Brand | Rounds of samples are spent converging on a target nobody described. |
| Ingredient constraints: required, excluded, origin, certifications | Brand | A sample is rejected for an ingredient nobody said was excluded. |
| Benchmark products, and what to take from each | Brand | The benchmark is copied in full when only one attribute mattered. |
| Packaging: format, material, decoration, compatibility needs | Brand, with the manufacturer on compatibility | Stability and compatibility work starts on the wrong pack. |
| Origin and status of the packaging: stock, adapted or exclusive | Brand and pack supplier | Exclusivity is assumed rather than contracted. |
| Target unit cost and retail price | Brand | The quote arrives far from the budget and the formula is reworked. |
| Volumes: first order, annual forecast, tolerance on minimum order | Brand, with the manufacturer | The quote rests on a volume that later changes the unit price. |
| Timeline: launch date and decision dates | Brand | The manufacturer cannot plan stability work or capacity. |
| Decision makers and approval steps | Brand | Samples wait for a decision nobody is empowered to take. |
The packaging status deserves its own line because it is easy to assume and costly to discover late. We look at why in Packaging Exclusivity: What the Eye-Patch Collision Teaches Brands.
Write constraints as ranges, not wishes
A field filled with an adjective gives the lab little to work with. A light texture can mean a dozen things. Lighter than one named benchmark and richer than another can be tested. The same applies to cost: a single target figure invites a single answer, while a range with a ceiling lets the manufacturer propose options at different points.
- Give a reference for every sensory target, and say what to take from it.
- Give a cost range and a ceiling, not a single figure, and always with the volumes it assumes.
- Say which claims are essential and which are desirable, so the lab knows what to protect if a trade-off appears.
- Name exclusions explicitly, with the reason: regulation, brand position or a retailer's requirements.
When the brief reaches the manufacturer incomplete
For a contract manufacturer, an incomplete brief is not a reason to wait. It is a reason to ask the few questions that change the quote. In our view, three matter most: the target markets, the cost ceiling with its volumes, and the claims the brand will not give up. Without them, a quote is a guess. Many other points can be settled with the first samples.
Asking these questions in writing, together with the assumption the manufacturer will use if no answer comes, keeps the project moving without hiding the uncertainty.
An illustrative example
In this brief, the manufacturer sees at a glance where it is free to propose (the preservative system, the test plan, the tube material) and where it must comply. It also sees that exclusivity is not part of the request, which avoids a misunderstanding later.
Common mistakes
- Sending a mood board in place of measurable targets.
- Naming a benchmark without saying what to take from it.
- Leaving the markets open, then adding one after the first samples.
- Giving a single cost figure with no ceiling and no volumes.
- Treating every claim as essential.
- Assuming that a pack shown by a supplier comes with exclusivity.
A brief written this way does not remove the need for samples and iterations. It makes each round answer a question someone has actually asked. It also follows naturally from the decision to develop, covered in How to Evaluate a Beauty Product Concept Before You Commit.
