Writing a clear product requirements brief

DIBA Trade Group editorial teamLast reviewed: 6 min read

In short

A requirements brief is the document every supplier quotes against, every sample is judged against and every inspection checks against. It does not need to be long, but it must be specific: what the product is, what it is made of, how big it is and how much variation you accept, how it is packed and labelled, and where it is going. This guide explains what to include, how to separate firm requirements from preferences and open questions, and how to keep the brief under control as it changes.

Why the brief does more work than any other document

Suppliers can only quote what they understand. If one assumes a thicker material and another a cheaper finish, their quotes look comparable but are not. The Trade Commissioner Service advises buyers sourcing from China to know their requirements and prepare proper drawings and specifications, and to ask for samples before production starts1.

The brief then follows the whole project. It is the reference for comparing quotes, for approving samples, for the purchase order and for the inspector's checklist. A gap in the brief tends to reappear later as a dispute about what was agreed.

What a useful brief contains

Product and intended use

Describe the product in one or two plain sentences and say who will use it and how. Intended use affects material choices and, often, which destination rules apply.

Materials and construction

Name materials as precisely as you can, such as a steel grade, a fabric weight or a wood species, and say how parts are joined. If you do not know the right term, describe the behaviour you need, for example “must not rust outdoors”, and mark it as an open question.

Dimensions and tolerances

Give key dimensions with units and an acceptable range. A drawing or annotated photo is better than words. Without a tolerance, an inspector has nothing objective to measure against.

Finish, colour and branding

Reference colours with a recognised colour system or a physical swatch, and describe the logo method, position and size.

Packaging, labelling and marking

Specify the retail packaging, the number of units per carton, the carton markings and any language or labelling the destination expects. Packaging failures are common and avoidable.

Quantity, destination and timing

State the destination country, a quantity range, the required arrival window and the delivery term you want quoted, such as an Incoterms® 2020 rule with a named place2. These shape price, lead time and which suppliers are realistic.

Compliance and documents

List the destination requirements you know of and those still to be confirmed. In Canada, CBSA's list of other government import requirements shows which departments regulate which goods3, and Health Canada's guide to the Canada Consumer Product Safety Act sets out duties for manufacturers and importers of consumer products4. For Saudi Arabia, a U.S. government trade guide describes SASO's SABER platform, with different routes for regulated and unregulated products5; in the UAE, MoIAT issues conformity certificates for regulated products under the Emirates Conformity Assessment Program (ECAS)6. Say who will arrange any testing. The brief records the requirement; it does not replace advice from the authority, your customs broker or a qualified testing provider.

Separate requirements, preferences and open questions

Mark every line of the brief with one of three labels. This tells suppliers where they can propose alternatives and where they cannot.

  • Required: the product fails without it. Suppliers must meet it or say clearly that they cannot.
  • Preferred: you would like it, but you will consider an alternative with a stated cost or quality trade-off.
  • Open question: you do not yet know. Ask suppliers to propose, and record who answered and how.

The same honesty applies to answers. When a supplier says a material meets your requirement, record it as Claimed until a document, a sample test or an inspection supports it.

Evidenced, claimed and unresolved
StatusWhat it means here
EvidencedThe approved sample was measured and matches the drawing within the stated tolerance.
ClaimedThe supplier states that the coating is suitable for outdoor use; no supporting test report has been reviewed.
UnresolvedWhether the destination requires a specific label for this product has not yet been confirmed with the customs broker.

Why “same as sample” is not a specification

A sample shows what is possible; it does not define what must be delivered. Samples get lost, age, or are remade slightly differently. Write down what the approved sample demonstrates, keep a signed and dated reference sample in your own hands or your representative's as well as the supplier's, and refer to both in the purchase order.

Version control

Give every brief a version number and date. When something changes, issue a new version, list the changes at the top and ask suppliers to confirm which version their quote or sample is based on.

Keep it short enough to be read

A brief for a simple product can fit on two pages plus a drawing. Put the essentials first: product, use, destination, quantity and timing. These are exactly the fields in our sourcing brief form, which is a reasonable first version. Add detail as it becomes known, rather than waiting for a perfect document before speaking to anyone.

Brief checklist

  • Product described in one or two sentences, with intended use and user.
  • Materials named precisely, or the required behaviour described.
  • Key dimensions with units and tolerances, supported by a drawing or annotated photo.
  • Colour referenced to a colour system or a physical swatch.
  • Logo method, position and size defined.
  • Retail packaging, units per carton and carton markings specified.
  • Destination country, quantity range, arrival window and delivery term stated.
  • Known destination requirements listed, with open ones marked and an owner named.
  • Each line marked Required, Preferred or Open question.
  • Version number and date on the document, with a change list.

Hypothetical example — not a client case

Buyer B turns a photo into a brief

Buyer B, a project buyer supplying furnished staff accommodation in Saudi Arabia, starts with a photo of a folding steel chair and a target quantity of a few hundred units (illustrative). Two suppliers quote quickly; their figures differ widely and neither states the steel tube thickness or the seat material.

Buyer B writes version 1 of a brief. Required: frame tube outside diameter and wall thickness with a tolerance, a seat that supports a stated load, powder-coated frame in a referenced colour, flat-packed with a stated number of chairs per carton. Preferred: a plastic seat in one of two colours. Open question: whether the product needs SABER registration as a regulated product, assigned to Buyer B's customs broker to confirm.

Re-quoted against version 1, the two suppliers' figures are now close, and one supplier states it can meet the wall thickness only with a longer lead time. That trade-off was invisible before the brief existed.

Supplier search & shortlist

Start with our sourcing brief form: the required fields — product, destination, and the support you need — are a workable first version, and the optional fields capture quantity, timing and a link to drawings. If you have a clear requirement but no supplier yet, our Supplier search & shortlist service confirms the specification with you, sends requests for quotation against it and puts the answers on a comparable basis. We work for the buyer. Scope, deliverables and fees are agreed in writing before work starts.

General information only — not legal, customs, tax or financial advice. Requirements change; check current official sources and qualified advisers for your product and destination.
