Quote matching desk
This page is the working console for lining up mill replies so two factory answers can be read side by side. Polypropylene Bulk Bags Sourcing remains an independent sourcing partner: we collect the brief, request missing evidence and list exclusions. We do not certify a plant, endorse a resin producer or promise a landed saving.
Fields we align
A unit price without a matching basis cannot be ranked. We ask each candidate mill to fill the same columns, then leave blanks visible instead of filling them with brochure language. Quantity may be stated in kilograms, metric tons, bags or pallets; mixing units on one line is a comparison error, not a rounding convenience.
Record chemical name, CAS number where known, intended conversion process, grade, form, melt flow, viscosity if the process uses it, and color. If the mill offers an alternative copolymer or a different bag GSM, park that offer on a new line so it cannot silently replace the original request.
Ask for the melt-flow method, density, moisture, ash, particle size if relevant and the certificate of analysis fields that will print on the commercial lot. A CoA template should list those fields, not a generic quality slogan. Assay language on this page means the mill-stated polymer identity, not a pharmaceutical potency claim.
List product subtotal, inner pack, palletization, samples, testing, freight, duties and destination charges as separate lines. An ex-works figure is not a delivered cost. Optional budget currency and per-unit versus whole-order basis help ranking; they are not a bid and they are not a verified supplier rating.
Request SDS, TDS, CoA format, TSCA or REACH statements, ISO quality-system evidence and transport classification for the quoted SKU. High-end, mid-range or economy preference describes buyer trade-offs around documentation and packaging, not a rating we have audited at a mill.
Document questions
Confirm revision date, polymer identity, flash point if listed, UN number if the pack is classified and handling statements match the quoted bag. Final storage and carriage follow that SDS, the carrier and applicable rules, not this website.
Use the TDS to see melt flow, density, solids content if filled grades apply, and stated color. Treat it as a supplier declaration to verify, not as a performance guarantee for any compounding or weaving line.
Ask which melt flow, moisture and impurity fields will print on the lot CoA. A historical CoA from another batch or plant is a sample of format, not evidence for the shipment you are buying.
Public product-family pages such as SpecialChem may help you phrase a melt-flow or density question. They do not prove availability or mill capability for your order. Continue with the inquiry range when the field list is ready, then read the buyer brief before ranking replies.
Once identity, quantity, destination and document questions sit on one sheet, submit the requirement so factory wholesale quotations can be compared on that sheet.
