How to Write a Product Brief a Factory Can Quote From

Sourcing Guide · 2026-10-08

Why the quote is only as good as the brief

When a factory returns a single figure with no conditions attached, it is usually because the brief left something open and the person estimating filled the gap with a guess. That guess may be conservative or optimistic, and you have no way of telling which until the sample arrives.

The practical consequence is worse than a bad number: you cannot compare two quotes properly unless both were priced against the same inputs, and you cannot hold anyone to a figure that rests on assumptions you never saw. Most of the work of sourcing is done before the quote arrives, in how clearly the product was described.

The eight things a brief has to answer

A brief does not need to be long. It needs to close every variable a factory must know before it can cost the job. In practice that is eight questions:

• What the product is — category, product form, and where it sits on the shelf
• What it should do — the functional direction and the claim you intend to make
• How it should feel and smell — texture, foam, fragrance family, colour
• How it will be packed — pack format, fill size, material, decoration
• How much of it — first order quantity and an approximate annual volume
• What it must cost — a target unit cost tied to a quantity and a pack
• Where it will be sold — the destination market or markets
• When it is needed — the target date for the first shipment

Anything you genuinely have not decided yet should be marked as open rather than filled in with a placeholder. A factory can quote a range across two options; it cannot quote against a decision you are going to reverse later without repricing the whole project.

Category and product form come first

Shampoo, conditioner, body wash, serum, cream, mask, gel, spray: each maps to a different production unit, a different filling line and, in China, often a different entry on the factory licence. Naming the category precisely at the top of the brief lets the factory answer in one reply whether it is the right plant for the job, instead of discovering it three emails later.

Specific enough to be filed

A regulator, a testing laboratory and a factory will all file the product under a category. "Hair care" is a department; "sulphate-free clarifying shampoo" is a product that can be costed. One line of precision here saves a round of questions.

Functional direction: describe the job, not the label

If you own a complete formula, supply it and say so. If you are starting from a target, describe the effect you want in terms of use: how the product should perform during application, after rinsing, and hours later; whether it should cleanse strongly or gently; whether the scalp should feel conditioned or clean.

Copying the ingredient list from a competitor label is the most common shortcut, and it usually costs time. A label states what is in the finished product, not the proportions, the grades of raw material or the process. Ask instead for the performance you are trying to match, and let the factory propose how to get there.

• How should it perform in use — foam, slip, rinse feel?
• What should remain afterwards — softness, weight, scent, no residue?
• What should it not do — no sulphates, no silicones, colour-safe, tear-free?
• Is there a benchmark product the factory can hold in its hands?

Describe texture, fragrance and colour by comparison

The fastest way to communicate a target texture is against something the factory already knows: thicker or thinner than a named benchmark product, more or less cushioned, matt or glossy. A comparison is unambiguous; adjectives such as "rich" and "light" are not.

For fragrance, name the family, the strength you want and whether it has to survive a rinse-off. The same fragrance oil behaves differently in a shampoo and in a leave-on cream, and the dosage that works in one can disappear in the other. If you have a fragrance house or a reference scent, say so in the brief rather than in the sample feedback.

Colour is a decision with a cost attached. A clear product is generally easier to reproduce consistently than a heavily pigmented one, and some colourants limit which markets the product can be sold in. If the visual appearance matters, state it early — appearance is formulated, not adjusted at the end.

Packaging decides more of the cost than most buyers expect

Bottles, tubes, jars, pumps and caps usually come from specialist suppliers with their own minimums, which can sit well above the factory filling minimum. Write the pack down in enough detail that the factory can price it or source it:

• Pack type — bottle, tube, jar, pouch, airless, pump, trigger
• Fill size, in the unit convention your market uses
• Material and appearance — clear, coloured, frosted, matt or gloss
• Decoration — label, silkscreen, hot stamp, sleeve, none
• Who supplies the pack — you, or the factory on your behalf
• Whether the pack is an existing stock mould or needs a new one

If the pack is still open, say that too. A quote covering two pack options and the price gap between them is more useful than a precise quote you will invalidate by changing the bottle.

Quantity, price and timing belong in the same sentence

Give a first-order quantity and a rough annual volume. The first order tells the factory what it has to set up; the annual figure tells it whether you are worth quoting keenly. A quote that assumes a reorder you have not mentioned is a quote you may not be able to repeat a year later.

Give the target cost with the quantity and the pack it refers to. "We need it under a dollar" is not a brief, because the factory cannot tell which of a dozen levers you expect it to pull. A statement such as "at 10,000 units in this pack we need to land near this figure" gives the factory something to design against — including the option of telling you it is not achievable.

State the target delivery date for the first shipment at the same time. It tells the factory whether it is quoting a normal lead time or a compressed one, and those two are priced differently.

Market and claims — the part buyers most often leave out

The destination market changes the formula and the paperwork. Labelling language, restricted and restricted-maximum ingredients, and the documents an importer will ask for are all set by where the product is sold, not by where it is made.

Claims belong in the brief for the same reason. Every claim has a formulation or documentation consequence, and asking for "sulphate-free" after the sample has been made is an expensive way to find that out.

• Which markets the product will be sold in, and in which packaging format
• Any claim you intend to make, and the evidence you expect to hold
• Labelling language and any artwork you already have
• Any destination-specific document your importer has asked for

Two ways a brief fails

Too vague

"A good shampoo at a competitive price" cannot be costed. The factory will guess, and you will receive a quote for a product you did not intend to buy.

Too prescriptive too early

Specifying the formula, the process and the pack in full before the factory has commented on feasibility tends to shut down the cheaper routes. The factory will quote exactly what you described, even where an existing base or a stock pack would have reached the same result sooner and for less.

The middle ground is a short document with decisions fixed and open questions clearly labelled. Factories price what you write; they cannot price what you meant.

What a good reply looks like

A quote you can actually work with has a recognisable shape. It names the variables it was priced against, says which one drives the cost, lists what still needs your confirmation, and gives a sampling timeline rather than a single delivery date.

• Which of the three variables sets your MOQ — formula, packaging, or filling setup?
• What assumptions were made where the brief was open?
• What is the unit price at your stated quantity, and at two times that volume?
• What has to be confirmed before sampling starts?
• How long does the first sample take, and what will it come with?

If the reply cannot answer those five questions, the brief is probably still open somewhere — and the fastest next step is to fill the gap rather than to negotiate on the number.
