Specification gate
Grade, form, density, melt flow, color and CAS where known. If a supplier offers a substitute, record it as a second row.
DOCUMENT GUIDE
Polyethylene resin suppliers quotes gated by documents
Before a polyethylene resin suppliers offer is treated as complete, lock the specification, document pack, packaging net weight and US destination. Alternative grades belong on a separate line with buyer approval, not inside a blended unit price.
Gates that stop mixed-basis pricing
Document gate
Current SDS, TDS and CoA format for the quoted product. Family literature can frame questions; it cannot close the gate.
Package gate
Bag, supersack or gaylord, liner, net content and pallet pattern. Changing net weight after pricing breaks the kilogram comparison.
Landed-scope gate
Currency, Incoterm, destination, freight, duties and sample charges. Missing lines stay missing instead of being treated as zero.
What this guide will not score
The table does not award points for claimed plant capacity, borrowed ISO badges or a promised percentage below another offer. High-end, mid-range, budget or undecided is a buyer preference about cost, appearance and service, not a rating this desk has verified. Optional budget must show currency and whether it is per kilogram, per package or for the whole order.
Assay, viscosity and solids content rarely apply to neat polyethylene pellets the way they apply to liquid binders, but melt flow, density, moisture and additive package still have to be written as numbers with units. A certificate of analysis that omits melt flow is incomplete for most converting programs.
Approvals that belong with the buyer, not the desk
The formulator or technical buyer. Polyethylene Supplier Sourcing records the alternate but does not treat it as equivalent until that reviewer says so.
EHS and the receiving site. UN number and dock rules are not decided on this website.
After product basis, currency, quantity, package contents, Incoterm and exclusions match. Until then the guide keeps the comparison paused.
Run the polyethylene resin suppliers comparison
Submit the locked specification, quantity, packaging and destination. Factory quotes will be lined up against those fields, not against an assumed catalog price.
