A brief that works with a domestic contract manufacturer will usually fail with a Chinese one, & the reason is rarely the language. Domestic briefs are often written as a conversation with a supplier who shares your market, your vocabulary & your assumptions about what a phrase like "premium feel" implies. Sent to a factory nine hours ahead with no shared frame of reference, the same document produces a first sample that answers a different question.
This article sets out how to write a brief that survives translation, distance & a first-time commercial relationship: the three questions a factory will ask before anything else, how to phrase technical requirements so they are not reinterpreted, which numbers belong in writing, how to handle claims without asking a factory to promise something it cannot, & the labelling details that decide whether the artwork round takes one exchange or three. Read it before you send the document & the first call becomes a working session instead of a clarification.
Why a brief written for a domestic supplier fails here
The first reason is missing context. A domestic supplier knows your category, your competitor set & the retail environment the product enters. A factory in Guangdong or Zhejiang may produce for twenty markets & will read your brief literally. Where a domestic brief leaves the market implicit, a cross-border brief has to state it, because the destination decides the preservative options, the labelling duties, the allergen thresholds & often the pack format.
The second reason is vocabulary. Words that carry a shared meaning inside one market do not survive export. "Clean", "clinical", "pharmacy-grade", "dermatologist-style" & "spa" are all meaningful in a pitch deck & nearly empty on a production floor. The floor needs a viscosity, a pH range, a fill weight, a colour reference & a fragrance load, none of which those words supply.
The third is that a brief written as a conversation assumes a feedback loop. In a domestic relationship, a vague line gets clarified in a phone call the same afternoon. Across a supply chain of eight hours & a language boundary, every vague line becomes a round trip, & a round trip costs days rather than minutes.
None of this means a brief has to be long. It means the parts that would have been settled by shared assumptions have to be written down instead.
The first three questions a factory will ask
The first question is which market the product is for. It is asked first because it is the most consequential. A preservative system permitted in one jurisdiction may be restricted in another, a colourant allowed for one use may be prohibited for another, & a labelling requirement in one market can add a panel that changes the carton size.
The second question is the quantity, & specifically the first-order quantity rather than the annual ambition. Minimum order quantity is set per line & per format, & it is a function of material loss, filling accuracy & line changeover rather than a negotiating position. A factory that hears "we plan to scale" without a first-order number cannot quote accurately, because the price of a small first run is genuinely different from the price of a large one.
The third question is what the brand supplies itself. Some buyers bring their own bottles, cartons, capsules or labels; others expect the factory to source everything. The answer changes the quotation structure, the risk allocation, & which party owns a delay when a component arrives late.
A brief that answers those three questions in the first paragraph saves a full exchange before the technical discussion starts.
Writing for translation: short sentences, numbers, no idioms
The most useful change a brand can make is to break long sentences into short ones. English written for a native reader often nests a condition inside a clause inside a qualification, & a translator working quickly will resolve that structure in one of two ways & not always the intended one. One idea per sentence survives the trip.
Idioms should be removed entirely. "Good enough to eat", "silky as a duvet", "the Rolls-Royce of textures" & similar constructions are untranslatable & will be rendered as something meaningless. The same applies to sports metaphors, military metaphors & anything borrowed from a television advertisement.
Numbers travel best of all. Where a requirement can be expressed as a number, write the number & the unit: fill weight in grams or millilitres, viscosity in centipoise with the instrument named, pH with the measurement temperature, colour with a reference standard. Where an attribute genuinely cannot be numbered, attach a physical reference instead: a photograph taken in stated light, a competitor product, or a retained sample.
Two smaller habits help. Avoid adjectives stacked before a noun, because the order of modifiers does not survive translation & the emphasis shifts. Write the acceptance criteria as a short list rather than as prose, so that a misinterpreted sentence is one item to correct rather than a paragraph to reinterpret.
The technical core: base, actives, claims, pack
A workable brief has four technical blocks, & each is more specific than it first appears. The base describes the physical system: an oil, a gel, an emulsion, a powder, a capsule fill. For an emulsion, the brief should say which phase is continuous, since an oil-in-water & a water-in-oil product behave differently, tolerate different actives & feel different on application.
The second block is the ingredient position. If the brand wants specific materials, they should be named by INCI name rather than by trade name, because a trade name belongs to one supplier & a different supplier's equivalent will have a different name. If a concentration is expected, state it as a range & say whether it is a target or a limit, since a formulator needs to know which direction is acceptable.
The third block is the pack, & it reaches further back into production than most brands expect. A single-dose capsule format brings questions about shell material, shell colour, fill weight & the blister count per card. A bottle brings questions about the closure, the orifice, the dose per actuation & whether the pack has to be compatible with a pump that the factory does not supply.
The fourth block is the intended position of the product, expressed without a claim. Position is legitimate brief content: it tells the factory the texture expectations, the fragrance level, the price band & the pack format. What it must not do is ask the factory to substantiate a statement that only the brand can defend.
Numbers that must be in the brief rather than in discussion
Certain parameters should always be written, because a verbal agreement on any of them is worth very little three weeks later. Fill weight with a tolerance is the most important, since it drives both the label & the filling line setting. Viscosity with the method is the second, because a number without an instrument, a spindle & a speed is not transferable between laboratories.
Colour needs a standard rather than a description. A Pantone reference, a retained sample or a photographed comparison against a grey card all work. "Soft pink" does not, & a sample produced against a verbal colour description is not evidence of anything except enthusiasm.
Where a fragrance is present, the brief should state the intended intensity on a scale & the market it is aimed at, because fragrance load requirements differ between regions & between rinse-off & leave-on products. The IFRA standards apply concentration limits by product category, & the twenty-six substances that must be named on a label above the applicable threshold are declared by the fragrance house. A brief that names the intended intensity makes it possible to check the load against those limits before the sample is made.
Two further numbers belong in writing where they apply. The first is the flash point of the finished product, which decides the transport classification & therefore the carrier, the documentation & sometimes the carton. The second is the shelf life the brand intends to claim, since it determines how much stability work is needed before launch & whether accelerated data alone will be enough.
Claims: what the factory can support
Brands often send a brief containing the marketing copy they intend to publish & expect the factory to confirm it. That expectation misunderstands the division of responsibility. A factory can confirm what is in the product, how it was made & what the standard tests show. It cannot confirm that a statement is permissible in a given market, because permissibility depends on local rules, on the evidence held by the brand, & in some markets on a registration decision.
The practical approach is to separate the brief into two parts. The first part lists the claim wording the brand intends to use, marked as a statement of intent rather than a request for validation. The second part lists the substance of the product, expressed in ingredients & effects on the product itself rather than on the person using it.
That second part is where the language has to be chosen with care. Descriptions of the product's own behaviour are usually safe: it spreads easily, it dries without tack, it remains stable in the stated pack. Descriptions that assert a physiological outcome belong to a different category & require evidence the brand has to hold, & in several markets they move the product into a regulated class with different registration duties.
The useful rule to send with the brief is that the factory will produce against a specification & will issue the documents it can issue, while the claim decision & the evidence behind it stay with the brand. Saying so at the start prevents an awkward conversation later, when a marketplace asks for substantiation & the brand discovers that the factory never promised anything in writing.
Labelling details that save a second round
Artwork revisions are the most common source of avoidable delay in a first project. Most of the causes are known in advance & can be settled in the brief. The nominal quantity & the unit convention, the ingredient list order, the allergen declarations, the batch code position, the best-before format, the responsible person or manufacturer address, & the recycling or disposal symbols the destination expects.
The dieline is the second cause. A carton cannot be designed without the correct dieline, & a dieline issued late forces the designer to work twice. Asking for the dieline in the first week costs nothing & removes a dependency from the critical path.
The third cause is the language of the pack itself. A product sold in several markets may need more than one language on the same panel, which changes the space available & sometimes the carton size. Deciding the languages in the brief, rather than after the first proof, avoids a resizing exercise in the middle of the artwork round.
A fourth detail is the barcode & the retailer's data requirement. Where the product goes into retail, the barcode has to be correctly sized & positioned for the retailer's scanning equipment, & the artwork is where that fails. Sending the requirement as a specification rather than a preference removes another revision.
Channels, time zones, one page at a time
Communication design is part of the brief. A working arrangement usually has three elements: a single channel for decisions so that nothing is agreed in two places, a named contact on each side with a nominated deputy, & a written confirmation after every decision call. The confirmation does not need to be long; a short list of what was decided & what is still open is enough, & it prevents a later disagreement about what was said.
Time zones are best handled by structuring rather than by waiting. Questions sent one at a time & answered one at a time consume a full day each. A batch of questions sent together at the end of the brand's working day is usually answered before the brand's next morning, which turns a nine-hour gap into an overnight cycle rather than a lost day.
The one-page rule helps more than any style guide. A brief that can be read in five minutes is read carefully; a forty-page document is skimmed, & the detail that matters may be on page thirty-two. The long documents still have a place, as annexes referenced by the one-page summary.
Photographs belong in the brief where a verbal description is doing too much work. A pale pink versus a rose pink, a matte versus a satin finish, a fine grain versus a coarse one: each of those is settled faster by two labelled images than by a paragraph of adjectives.
Separating what is fixed from what is still open
A brief that does not distinguish between a requirement & a preference will be read as though everything is a requirement. The result is a sample that satisfies the strict parts & ignores the parts the brand cared about most. Marking each line as fixed, preferred or open costs nothing & changes how the document is used.
Fixed items are usually the destination market, the format, the fill weight band, the pack type & the claim position. Preferred items might be the exact texture, the fragrance direction & the colour. Open items are genuinely negotiable & are where a factory's experience is most valuable, since a substitution can sometimes reduce cost or lead time without changing what the customer experiences.
Saying explicitly where the factory's judgement is welcome also changes the quality of the response. A factory asked to reproduce a specification exactly will do so. A factory told which two attributes are negotiable will often propose a version that is easier to make, more stable or cheaper, & those proposals are one of the practical benefits of working with a manufacturer that runs dozens of similar products.
Brief sections compared
The table below sets out the sections a cross-border brief normally contains, what a factory reads each one for, & what tends to go wrong when the section is left vague. It is a working comparison rather than a template to be copied without thought.
| Brief section | What the factory reads it for | Cost of leaving it vague | Best form |
|---|---|---|---|
| Destination market | Which ingredient & labelling rules apply | Formula restricted after sampling | Named countries plus the sales channel |
| Product format | Which line & which fill method | Quotation for the wrong process | One line with the pack type |
| Base & texture | How to build the physical system | Sample answers a different question | Reference product plus sensory scale |
| Ingredient position | What to source & at what grade | Substitution the brand did not intend | INCI names with target ranges |
| Fragrance position | Load, allergen duties & documentation | Reformulation after the sample | Intensity on a scale plus market |
| Fill weight & tolerance | Label quantity & line setting | Relabelling or a rejected batch | Target plus percentage tolerance |
| Pack & artwork | What is ordered & who approves | Late plate & die orders | Dieline request plus language list |
| Claim position | What may be printed & what is tested | Unsupported wording on the market | Intent noted, not requested as validation |
Those rows are a comparison of emphasis rather than a fixed document structure, & a proven base product needs fewer of them than a full development project. What does not vary is the value of writing down the parts that a domestic relationship would have left to assumption.
What to put in the brief
Keep the summary to one page & put the detail in annexes that are clearly labelled. Write the market, the quantity, the format & the pack in the opening paragraph. Then state the acceptance criteria as a list of numbers, mark each item as fixed, preferred or open, & say who inside the brand has authority to approve a sample.
- The destination markets & the sales channel for each one.
- The first-order quantity & the expected reorder cadence.
- The product format, fill weight target & the tolerance you will accept.
- The reference product, with the attributes you are copying & the ones you are changing.
- Ingredients to be included or excluded, named by INCI rather than by trade name.
- The fragrance direction, intended intensity & the documentation you expect with the sample.
- The pack type, who sources it, & the languages that must appear on the panel.
- The claim wording you intend to publish, marked as intent rather than as a request.
Send the brief with the annexes & a short list of the questions you want answered in the first call. A factory that receives a one-page summary, a numbered annex & three clear questions can usually come back with a costed proposal & a realistic timeline without a second clarification round.
Where our capability fits
We read briefs in the form they arrive & reply in writing with what we can make, which line it would run on, what the first-order quantity would be, & which items in the brief are open to substitution. Where a requirement cannot be met at your volume, or where an ingredient position is restricted in one of your destination markets, we say so in that first reply rather than after the sample. Samples are issued with the formula version, the fill weight & the raw material lots used, so that an approval refers to a specific product.
We work with brands on private label (your brand on a proven base), OEM/ODM contract manufacturing & full custom formula development, & the brief format is the same for all three. Our lines include custom softgel capsule face serums, a copper peptide serum & a hydrating repair face cream, each quoted with the pack components, the fill tolerance & the documents listed separately.
Send us your one-page brief & the annexes, & we will come back with a line recommendation, a first-order quantity & the questions we still need answered before quoting. 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. How a brief becomes a production brief is set out in our formula development guide, & the communication habits that prevent most errors in our article on factory communication.
General manufacturing information, not regulatory or legal advice. Ingredient restrictions, claim rules, labelling duties & transport classifications vary by market & by product, & the applicable requirements should be confirmed for each destination before a product is placed on sale.
