Freeze the identity
Record trade name, chemistry family, CAS number where known, and whether pellets, liquid resin, film, prepreg or another form is required. If the mill proposes a substitute, keep it on a second line until the buyer approves.
Supplier matching desk
Normalize one composite materials manufacturer RFQ before ranking mills
The matching desk turns a buyer brief into the same questions every factory can answer: grade, form, viscosity or melt flow, color, quantity, packaging, US destination, SDS/TDS/CoA format and sample intent. Composite Materials Sourcing does not substitute a platform catalog for your specification. We do not own a compounding line and we do not endorse a mill until written answers return for the exact quoted product.
RFQ control fields
- Chemical name and CAS number where known
- Grade, purity or concentration, form
- Quantity unit and packaging construction
- Destination, timing, Incoterm request
- Evidence list: SDS, TDS, CoA, TSCA/REACH status to confirm
Requirement cards
Force inclusions and exclusions onto separate lines
Manufacturer quotes often hide drum deposits, moisture-barrier bags, CoA testing, export packing or hazardous-goods paperwork inside a kilogram price. The cards below are how we keep those lines visible. They are process checks, not a claim that a named mill has capacity, ISO 9001 coverage or TSCA listing for your SKU.
Measure the chemistry
Ask for assay or purity, viscosity, melt flow, density, moisture, color and any active or solids content that your process uses. Unknown values stay labeled unknown rather than filled with typical catalog midpoints.
Split the commercial buckets
Request product subtotal, packaging, samples, testing, freight, duties and destination charges as separate figures, with currency and validity. An ex-works number is not a landed comparison.
Bind evidence to the SKU
ISO quality-system, REACH, TSCA, GMP, DOT or IMDG statements are useful only when the supplier maps them to the quoted concentration, plant and lot. A competitor brochure cannot be reused as this site's credential.
Document checks for manufacturers
Which files still sit with the mill?
Ask for the fields the mill actually issues: assay, viscosity or melt flow, moisture, color, and lot identification. A blank template is not a certificate for a future lot.
Place each alternative on its own row with its own SDS/TDS reference. Do not average prices across different resin contents, tack windows or moisture specifications.
Only the criteria you named. Identity, appearance, processing behavior and packaging can be checked separately. Laboratory and EHS decisions stay with the buyer after the exact SDS arrives.
Compare sourcing options
Send the manufacturer brief
Name the resin, prepreg or compounding grade, the kilograms or drums, the US receiving plant, and the date you need a first lot. Optional budget and high-end / mid-range / economy preference stay buyer guidance, not a mill score we have verified.
