Commodity pellets
Polyethylene and polypropylene grades used in molding or extrusion. Record melt flow, density, additive package and whether the lot is virgin, recycled or a blend. A family SDS does not replace a lot CoA.
EVIDENCE BOUNDARY
What a thermoplastic quotation must confirm before prices are compared
A catalog name such as thermoplastic, polypropylene or hose compound can hide different molecular-weight bands, stabilizer packages, recycle content and color. The table is a buyer check. It does not claim that any supplier, assay, TSCA listing or transport class has already been verified for this desk.
| Field | Buyer records | Supplier must answer | Status until confirmed |
|---|---|---|---|
| Grade / melt flow | Requested MFR window or open for proposal | Quoted melt-flow method, load and typical value | Open |
| Form and color | Pellet, powder, compound; natural or specified color | Stated form, particle size and color for the SKU | Open |
| Viscosity, density, moisture | Process window if known | Typical values at a stated temperature | Open |
| Packaging | 25 kg bag, gaylord, octabin or bulk | Net fill, liner, palletization | Open |
| Documents | SDS, TDS, CoA, TSCA or REACH questions | Exact-product files, not a family sheet | Open |
PRODUCT FAMILY ROWS
Polymers and resins inquiry families used on this desk
Rows below organize how a thermoplastic suppliers brief is usually split. They are not a stock list, approved plant roster or certified SKU catalog. Click through only after the grade and pack questions are written.
Engineering resins
ABS, polycarbonate and related families. Record moisture limits, color, molecular-weight band and any filler. Unknown assay or purity values stay labeled unknown rather than filled from a brochure midpoint.
Hose and compound grades
Compounds requested under thermoplastic hose manufacturers language. Record hardness, oil resistance questions, color and pack. This desk does not rate hose working pressure; that stays with the buyer’s qualified reviewer after the exact SDS arrives.
Distribution packs
When a thermoplastic resin distributor is the intended receiving role, record relabel language, bag mix and whether one CoA can follow a resale lot without blending plants.
Continue to the application field matrix, the document guide, or the procurement brief.
PACKAGING AND TRANSPORT
Logistics questions that change a thermoplastic landed scope
Why must bag, gaylord and bulk stay on separate quote lines?
Net fill, residual heel, moisture barrier and destination equipment differ. A 25 kg bag price cannot be compared to a gaylord or silo fill until currency, quantity, Incoterm and package contents are aligned. Ask the supplier to state liner, pallet pattern and whether desiccant or foil lining is included.
Who assigns UN number and flash point?
Transport classification, packing group and flash point come from the exact-product SDS and the quoted concentration. Thermoplastic Suppliers Sourcing does not assign UN numbers or write DOT or IMDG instructions. Final carriage follows the SDS, carrier rules and the destination site procedure.
What stays open until the destination is named?
US city, receiving hours, silo or dock limits, winter pourability for certain compounds and any site ban on a package type can change freight and residual cost. Leave those items visible instead of treating a factory EXW number as a delivered total.
REQUEST FACTORY QUOTES
Send the thermoplastic suppliers brief after this checklist
Write polymer identity, bag or gaylord pack, US city and the SDS/TDS/CoA files still missing. A planning budget in USD may sit on the same brief. No lowest-price or savings percentage is published.
- Grade, melt flow, viscosity, density, moisture and color are written or marked unknown.
- Quantity unit, pack type and US destination sit on one line.
- SDS, TDS and CoA requests are bound to the quoted SKU, not a family brochure.
- Open items remain visible instead of being filled with catalog defaults.
