Most briefs written to a factory are written like a pitch. They open with the story of the brand, explain the customer, describe a feeling, & close with a request for the best price. A costing desk cannot use any of that. What it can use is a short list of hard facts, & the briefs that get quoted fastest are usually the least exciting ones to read.
This article sets out how to write a brief that a factory can price without a second round of questions: what belongs in it, in what order, which decisions belong to you & which belong to the factory, & what to leave out because it makes the project harder to cost rather than easier. The aim is a document you can send once & get a usable scope back from.
Why a brief is a costing document, not a pitch
A brand writes a brief to communicate ambition. A factory reads it to find the inputs that price a job: what is being made, how much, in what pack, for which market, on which formula lane. These are two different documents with two different shapes, & when the first is sent in place of the second, the reply is a questionnaire rather than a scope.
The practical consequence shows up as a delay that is hard to attribute. Nobody refused the project. The information simply was not there to cost it, & the sales desk, which is paid to close work it can define, moves on to the enquiries it can define. Two weeks later the brand is chasing an answer that was never going to arrive.
There is a useful test before sending. Read the brief & ask whether a stranger could order materials, book a line & quote a unit cost from it. If the answer is no, the missing item is usually one of four things: fill volume, pack, volume band or market. Those four carry more of the cost than any other line in the document.
The one-page structure that works
The structure that costs fastest has six blocks in a fixed order: the product & its physical form, the market of sale, the volume plan, the pack, the formula lane, & the commercial frame. Put the facts you cannot change first, because those are the constraints the factory has to design around, & everything else is negotiable.
Keep the brief itself to about a page. Longer documents are not read more carefully, they are read more selectively, & the risk is that the factory prices the three lines it noticed. Anything visual & anything narrative belongs in an appendix: reference images, mood, brand assets, existing artwork. An appendix is allowed to be atmospheric because it is not carrying a number.
Write in short declaratives, one fact per line, & avoid advisory language. A brief that says the brand would ideally like something quite natural & gentle has said nothing, while a brief that says fragrance-free, silicone-free, aiming at a light gel texture, 12-month shelf life target has said four things a formulator can act on.
Position & price point: the input buyers leave out
The single most useful commercial line in a brief is the price band the finished product is intended to sell at, & the channel it sells through. That one line sets the pack tier, the fill volume, the decoration, & the depth of development that is affordable. A brief without it invites a formula for a different shelf from the one you intend to occupy.
This is not a request for the factory to design down to a number. It is a request for the factory to tell you which combinations are achievable inside the band you are aiming at, & where the band is unrealistic for the specification you have described. A supplier that answers that honestly is more useful than one that agrees with every specification & then quotes a number you cannot launch with.
Include the retail channel as well, because it changes more than price. A product sold through a marketplace needs artwork that survives a small image, a pack that survives parcel transit, & documents that satisfy platform checks. A product sold through a salon or a clinic channel may carry a larger pack, different secondary print, & a different claim set. Same formula, different brief.
Describing the formula without writing it
The brief should describe what the formula has to do, not how to build it. Target texture, spread, absorption, afterfeel, scent level, colour, & the conditions the product will be used in all belong in the brief. Percentages for individual ingredients usually do not, because a percentage given without knowing the rest of the system constrains the formulator for no benefit & creates a dispute if the finished product performs well at a different figure.
What must be absent matters more than what must be present, & this is where new brands under-specify. If the product has to be free from silicones, fragrance, essential oils, alcohol or a particular preservative family, saying so at the brief stage saves a reformulation later. The same applies to a certification the brand intends to pursue, because the standard constrains the ingredient list & the process before the formula exists.
Where a target product exists, name it & define the match. A match can be close on texture & feel without copying the ingredient list, & it can be defined in a sentence: same cushion on application, lighter afterfeel, no fragrance. Naming a reference gives the formulator an achievable target & gives you a fair basis for judging the sample. The full route from brief to first sample is set out in our guide to formula development from brief to production.
Claim wording & what the brief can promise
If you intend to print a claim, put the wording in the brief & ask which evidence supports it. Claims about moisturising, smoothing, appearance or sensory benefit sit inside cosmetic rules; claims that describe a medical outcome do not, & a brief that asks the factory to make wording true is asking the wrong party. The honest version of the question is what can be said, & what has to be removed or reworded.
Claims carry a testing consequence, & that consequence belongs in the costing. Some wording is supported by consumer use studies, some by instrumental measurement, & some by nothing more than a formula description. Because the brand is the one answerable for what is printed, the brief should record who commissions the test & who holds the report. The boundary between wording that can be defended & wording that cannot is covered in our article on claim substantiation.
A practical rule is to write claims last, after the specification is fixed, & to write them as a short list rather than as marketing copy. Three claims the formula can support are worth more than ten lines of copy that has to be cut at the artwork stage, when the printed pack is already in production.
Packaging as a commercial decision
The pack is where a brief most often splits into two documents: a design the brand has already approved, & a specification nobody has costed. Write four lines & regard none of them as a detail: the primary container, the closure or applicator, the decoration, & the secondary packaging. Each line is a separate purchase with a separate lead time.
The pack also constrains the formula, & this is the part that surprises first-time buyers. An airless pump, a dropper bottle, a tube & a wide-mouth jar each place different demands on viscosity, preservation & compatibility with the fill. A formula developed for a pump can behave differently in a jar, & a fill containing an alcohol or an essential oil can interact with a liner, a gasket or a decorative coating.
Say in the brief which pack decisions are already locked & which are open. If the container shape is fixed, the factory can check compatibility & work backwards. If it is open, ask for two options at the price band you named, because a pack comparison is far cheaper to run on paper than after the mould is cut.
Markets, channels & who holds the documents
Name every destination, including the ones you plan to enter within a year, & name the person or role inside the brand who will hold the product file. That single line tells the factory how deep the documentation has to go, & it prevents the situation where a formula is fixed for one market & then has to be reworked for another before launch.
Ask for the document list in the brief rather than near shipping. Say what you need issued per formula & what you need per batch, because those are different requests answered by different departments. Where a document comes from a raw material supplier rather than from the factory, ask for that to be identified in the reply, so you know which gap is yours to close.
If you sell through retailers or marketplaces that run their own supplier checks, say so. Their questionnaires overlap with a regulatory file but do not match it, & a factory that knows about them at the brief stage can prepare the evidence once instead of assembling it twice under time pressure.
Volume plan & the shape of the range
Give two numbers: a first order band & a twelve-month band, both described as planning figures. Then describe how the range grows. A single product that later becomes three shades, two scents & a travel size is a range plan, & it changes how the factory sets minimums, because each additional variant carries its own bulk, its own filling run & often its own component minimum.
If the ambition is a full range, the cheapest route is usually a sequenced launch rather than a simultaneous one. Launch the core item, prove the sell-through, & add variants once the first order has moved. That keeps the first commitment to one production set-up while preserving the plan, & it means the second order can be placed against a product that is already known to work.
Say whether the brand expects to repeat the order within the year, because repeat intent is a costing input even when the second order is not committed. A factory planning material purchases is more comfortable quoting tightly against a repeatable line than against a one-off run it may never see again.
What to leave out of a brief
Leave out instructions that contradict each other, because the factory will either ignore one or price the difficulty. A product that must be preservative-free, entirely natural, in a jar, with a long shelf life & a pH above 5.5 has described a set of requirements that fight each other in a water-based system. Contradictions are not a negotiating position; they are a signal that the brief has not been thought through.
Leave out the ingredient list of a competitor pasted in full with a demand for the same. Ingredient lists are declarations, not formulations, & they say nothing about ratios, process or the grade of a material. They also invite a copy that no factory can honestly promise & no brand can legally protect.
Leave out claim wording that has already been published, unverified test numbers, & any legal or regulatory wording copied from another market. A brief is a working document, & anything inside it may end up as an instruction. The safest habit is to include only what you are prepared to stand behind in writing.
The brief, section by section
The table below sets out the sections of a workable brief, what belongs in each, who normally owns the decision, & the error that shows up most often.
| Section | What to write | Who owns the decision | Common error |
|---|---|---|---|
| Product & form | Fill form, fill volume, format family, sensory target | Brand, confirmed by factory | Described by category rather than structure |
| Formula lane | Proven base, adapted base or full development | Factory advises, brand decides | Development requested on a sampling budget |
| Free-from list | What must be absent, plus any certification sought | Brand | Restrictions that conflict with the shelf-life target |
| Market & channel | Destinations, marketplaces, retailer audits | Brand | Market added after the formula is fixed |
| Claims | Intended wording, with the testing consequence accepted | Brand, tested by factory or laboratory | Claim added after sampling with no testing budget |
| Pack | Container, closure, decoration, secondary pack | Brand | Pack chosen without a compatibility check |
| Volume plan | First order band, twelve-month band, range growth | Brand | One SKU priced, a range of five launched |
| Documentation | What is issued, by whom, in which language | Both, agreed in writing | Requested in the week before shipping |
These are relative comparisons rather than fixed values. The weight of each section moves with the project, & a brief for a stock base in a stock pack can be short while a brief for a new moulded pack & a new formula cannot.
Reading the reply against the brief
When the reply arrives, read it against the brief rather than against expectation. Every section you wrote should appear in the response, or be explicitly identified as an open point. Sections that vanish quietly are usually the ones that reappear later as a change order, & a change order always costs more than a line written into the first scope.
Ask which assumptions the number rests on, & ask for a list of deviations from your specification. A good reply often contains a proposal to change something: a different base, a different pack, a simpler decoration. That is not a refusal, it is the factory applying knowledge you do not have, & it is worth reading carefully before rejecting it.
Finally, keep a dated version of the brief. When a project runs over three or four months, the difference between what was asked in March & what is being produced in July is normal, but only if both sides can see it. A brief with a version number turns an argument into a comparison.
What to put in the brief
The list below is the working version of everything above, in the order a costing desk reads it.
- The fill form, fill volume & format family, described by structure rather than by category.
- The sensory target: texture, spread, afterfeel, scent level & colour direction.
- The free-from list & any certification the brand intends to pursue.
- The markets of sale, the channels, & who inside the brand holds the product file.
- The claims you intend to print, with the assumption that testing has to support them.
- The pack, split into container, closure, decoration & secondary packaging.
- The first order band & the twelve-month band, both labelled as planning figures.
- The documents you need issued, & whether they are per formula or per batch.
Then add one line naming the decision you want from the factory: an indicative cost, a scoped development proposal, or a matching exercise against a reference product. A brief that asks for one clear thing is answered faster than a brief that asks for everything at once.
Where our capability fits
Send us a brief in the six blocks above & we will come back with a scope rather than a questionnaire: the lane we would use, the pack options that fit the price band, the testing your claims imply, & the documents we can issue against a list that says who supplies what.
We work with brands on private label (your brand on a proven base), OEM/ODM contract manufacturing & full custom formula development, & we will tell you plainly when the lane you asked for is more than the brief requires. Our ranges include a hyaluronic acid serum capsule, a vitamin C brightening face cream & a hydrating repair face cream, each of which can be matched, adapted or rebuilt from the brief.
Tell us the product, the price band & the market, & we will write back with what is achievable inside them, including the parts we would change. Start at our inquiry page, email capsulebiotech@163.com, or message the right team on WhatsApp: Capsule Series (capsules only) +86 158-7655-5319, Cosmetics Series (serum, hair care, body care, fragrance) +86 158-7655-5319. The document set most briefs end up needing is listed in our guide to the documents required for private label brands.
General manufacturing information, not regulatory or legal advice. Ingredient restrictions, claim limits, labelling duties & document requirements vary by market & by product, & the applicable rules should be confirmed for each destination before a product is placed on sale.
