Garment bill of materials for production in Turkey: a buyer’s BOM checklist

Use the BOM for components and the tech pack for the complete garment

The bill of materials records what goes into or accompanies the finished product. The wider tech pack also explains measurements, construction, artwork placement, grading, finishing and packing instructions. A BOM therefore belongs with the product file; it does not replace the drawing, measurement chart or sample comments.

Start each document with the same style code, product name, season and revision. When the BOM and technical pages use different identifiers, an approved component can easily be attached to the wrong sample or colourway.

List every component that the style actually requires

Build the list from the garment outward: main fabric, contrast or lining fabrics, rib, pocketing, interfacing, sewing thread, elastic, drawcord, buttons, zips or other hardware. Then add brand components such as the main label, size label, care label, hangtag and any print or embroidery reference.

Include individual product packaging and identifiers when they are part of the manufacturing brief. Do not copy unused rows from another style simply because a template contains them. Each line should describe a real item needed for this garment.

• Fabric and supporting materials
• Trims, closures and hardware
• Labels, artwork and decoration
• Product packaging and identifiers

Make every BOM line independently identifiable

Give each component an item code and plain-language description. Record the material or composition where relevant, construction, dimensions, colour, finish, placement, unit of measure and the proposed supplier or article reference if one exists. Attach a photo, drawing or swatch identifier when words alone could describe several alternatives.

Keep requested consumption or quantity per garment separate from the component specification. Mark whether that figure is a buyer target, a sample reference or a production value still to be confirmed. This prevents an early estimate from being treated as a final purchasing instruction.

Map components to colourways and sizes

A single style can use different thread, rib, zip, label, artwork or packaging references across colourways. Create a matrix that shows which component applies to each garment colour instead of writing ‘matching’ without a controlled reference. Where one item is shared across every colour, state that clearly.

Identify size-dependent components such as size labels, graded artwork or variable packaging data. Connect the BOM to the same size and colour codes used in the purchase order, measurement chart and packing instructions so changes can be reconciled across the complete product file.

Assign sourcing and approval responsibility

For every line, state whether the buyer supplies the item, nominates a supplier or asks the manufacturer to coordinate sourcing. Record who approves the material, colour, artwork, physical proof and substitute. This is especially important for branded components that should not be ordered or reused without the buyer's written authority.

If the buyer supplies a component, agree the required identification, delivery point, quantity record and incoming review. If the manufacturer proposes it, request the supplier or article reference and the appropriate swatch, sample or proof before the line is marked approved.

Use approval status instead of informal comments

Add a status field such as proposed, submitted, revised or approved, together with the relevant sample, swatch or proof identifier and approval date. A note in an email is difficult to trace if the BOM still shows an earlier reference. The controlled document should make the current decision visible.

Define the substitution route before production. If an approved fabric, trim or supplier article becomes unavailable, the replacement should return to the required review rather than being accepted because its description appears similar. Record who can authorise the change and which sample or test must be repeated.

Connect the BOM to quotation and sample review

Ask the manufacturer to identify which BOM lines are included, excluded, buyer-supplied or still provisional in the quotation. A garment price cannot be compared responsibly when one scope includes labels, decoration and packing while another assumes the buyer will provide them.

During sampling, inspect the finished garment against the BOM as well as the drawing and measurements. Confirm fabric, trims, colours, brand components, decoration and packaging by their controlled references. Record open items instead of approving the whole style while a component remains undecided.

Freeze a revision and control later changes

Before a production release, issue a dated BOM revision that shows the approved lines and any authorised exceptions. Preserve the corresponding sample and product-file revisions. A later change to fabric, colour, supplier, dimensions, artwork or packaging should create a new revision rather than overwrite the record used for the original decision.

For a repeat order, compare the new request with the last approved BOM line by line. Reconfirm availability and identify any component that needs a fresh swatch, proof or sample. This keeps repeat production tied to evidence rather than to an item name remembered from an earlier order.

Send Konsey Textile a BOM-ready enquiry

Konsey Textile's private-label and custom-clothing routes can coordinate product development from buyer documentation, including fabric direction, samples, printing or embroidery requirements, labels, finishing and packaging. Send the tech pack or reference garment together with the BOM, colour and size breakdown, artwork files, target quantities and the approvals already completed.

Ask the team to mark which lines require clarification, sourcing review or a physical approval for the specific programme. Workable quantities, pricing, timing and the sourcing route should be confirmed only after the complete style and component brief has been assessed.

Turn the BOM into an approval register

For one hoodie, give the shell fabric, rib, drawcord, main label, care label, embroidery and individual packaging separate item codes. Map each item to the relevant colourways, supplier reference, approval proof and current status. If the rib changes, the register shows exactly which material and sample decisions must be reopened.

• Component code and complete specification
• Colourway, size and sourcing responsibility
• Approval proof, date and revision
