Garment bill of materials: prepare a traceable buying brief.

List the components, not just the fabric name.

A garment bill of materials, or BOM, is the component list within the product brief. For this proposed buyer record, that means the fabrics, trims, labels and packing components needed for the identified style. A material name alone leaves the reference, intended use and decision state unclear.

The complete clothing tech pack also covers construction, measurements, artwork and revision history. This page goes deeper into one job: making a component line traceable. It does not replace the full pack, recommend material values or describe a verified HACOLD factory procedure.

Give every line a stable identity.

Agree a record format with the people who will quote, source and review the material. The fields below are a proposed starting point, not a universal mandatory template.

Style and revision

Identify the style, colourway, BOM revision and date. State which tech-pack revision the list belongs to.

Component and location

Assign a stable component ID and describe where it is used: body, neck, cuff, waistband, label position or packing layer.

Controlled reference

Link the description to the intended article, swatch, trim sample or artwork file. Record the revision of that reference rather than relying on an image in an old message.

Specification and colour

Record the agreed material description and applicable characteristics. Identify the colour reference and keep a disputed or unconfirmed requirement visibly open.

Quantity basis

Give the unit and whether the value is per garment, per pack or for an order. Separate an initial estimate from a consumption figure that has been technically reviewed.

Responsibility and status

Say who supplies or proposes the component, who reviews it, what remains unresolved and which reference the eventual decision covers.

A fictional T-shirt material record.

These invented rows demonstrate the fields, not a complete production BOM. They contain no recommended composition, weight, consumption, supplier or approved manufacturing specification. An incomplete example is not ready for costing or ordering.

Use the existing buyer toolkit BOM sheet for your own working record. Add all components actually needed for the style; do not copy these illustrative codes into a supplier instruction.

A number needs its unit and its basis.

Before using a material quantity in a comparison, ask what it measures. A length per garment, a mass per garment and an order-level purchase quantity are different inputs. Write the intended unit beside the value and identify who checked the basis.

• Keep per-garment use separate from order-level material requirements.
• Identify whether an allowance is included and how it was reviewed; do not silently add a generic percentage.
• Check whether sizes or colourways need different component references or quantities.
• Leave unknown consumption visibly unconfirmed rather than entering zero.

The manufacturing-cost guide explains cost inputs. This record does not calculate a garment price or guarantee material availability.

A proposed substitute stays a proposal.

Suppose the original FAB-A reference cannot be supplied and an alternative is offered. Keep the original reference in the record, identify the proposed alternative and ask which characteristics and project assumptions would change.

1. Identify the affected component and the reason for the proposal.
2. Record the alternative reference, comparison evidence and questions requiring review.
3. Ask whether the change affects fit, construction, colour, care, price or the timing plan.
4. Record the reviewer, decision, date and exact scope. Update the controlled documents only after the relevant decision is made.

Separate a quotation input from a material approval.

A supplier may need to quote a proposed component before it is approved. Keep the basis explicit so an estimate is not mistaken for a final material decision.

Identified reference

Send the component ID, current reference and intended location. Ask the supplier to state what that quotation includes and which material details remain unconfirmed.

Supplier proposal needed

Describe the intended garment and required characteristics. Request an identified material proposal, its quotation basis and the evidence needed for review; do not mark the component approved.

Substitution or open quantity

List the affected component and unknown consumption or availability. Ask which price, sample or timing assumptions depend on the answer before comparing quotations.

The useful output is a short open-items list: component, question, responsible person and next decision. A blank consumption field means unknown, not zero cost. The cost guide owns the broader price-driver question.

Send one current material brief.

Issue the BOM with the matching tech-pack revision, the referenced swatches or files and a short list of open questions. Distinguish buyer-supplied material from supplier-proposed material and ask for the responsibilities to be confirmed for the project.
