What is bill of materials?
A bill of materials — BOM — is the list of everything a garment is made of: body fabric with composition and weight, rib, thread, zips, drawcords, eyelets, interfacing, labels, hangtags, polybags, cartons. Each line carries a specification or supplier reference.
Why it matters
It is what the factory sources from. A BOM that says '500 gsm brushed-back cotton fleece, 1×1 rib, YKK #5 zip, woven label per artwork' gets the right hoodie; one that says 'hoodie fabric' gets a guess.
On our floor
Built for every cut-and-sew order and priced line by line — which is also how a quote becomes itemised rather than a single number.
Common questions
- Do I need to know every trim?
- No — we complete the BOM from your reference garment or brief and you approve it.
- Does the BOM affect price?
- Directly: each line is a cost. It is also where savings are found — a different rib, a standard zip.
- Is packaging in the BOM?
- Yes — polybag, hangtag, carton and carton marks.
- Is the BOM kept for reorders?
- Yes, with the pattern and artwork.
