Specification brief beside sealed masterbatch bags

Supplier matching, not mill ownership

Masterbatch manufacturer answers compared on one sheet

This page shows how Masterbatch Sourcing restates producer quotation fields. Each proposed masterbatch manufacturer is asked the same carrier, load, package, document and delivery questions so a unit price is not compared across mismatched lots.

A color house that only reprints a shade card is not offering the same concentrate as a plant that writes lot-controlled pigment load and melt flow. Those differences stay on the sheet. Mill capacity, authorization and a preferred factory roster are omitted because they are not in this site record.

Matching work that stays inside the brief

When a buyer asks for a masterbatch manufacturer, the desk does not advertise a preferred mill. Open questions are rewritten into fields a producer can answer, and alternative grades stay on separate lines until substitution is accepted.

Normalize identity

Confirm whether the intended material is a color, white, black or additive concentrate, which carrier resin is required, and whether recovered pigment is acceptable. A producer name is recorded only as a proposed source, never as this site’s factory.

Align measurable limits

Put melt flow, viscosity, moisture, color coordinates and let-down ratio on the same units. If a manufacturer offers a typical value instead of a lot limit, that difference stays visible so purchasing and quality can decide separately.

Request the same documents

Every quotation should state which SDS, TDS and CoA format will be supplied. TSCA inventory status, REACH statements or ISO quality-system files are asked as evidence for that product, not as credentials of Masterbatch Sourcing.

Keep delivered scope visible

Freight, pallet pattern, temperature limits and hazardous-material paperwork change total cost. We ask each manufacturer to mark inclusions and exclusions instead of inferring a delivered price from an ex-works number.

Questions we send to a masterbatch manufacturer

Is the CoA lot-controlled?

Ask whether pigment load, melt flow and moisture are measured on the shipped lot or copied from a historical typical sheet. A historical sheet cannot close a receiving inspection.

Which transport class is proposed?

UN number, packing group and flash-point statements must match the quoted concentrate and package. Final carriage still follows the exact SDS, carrier rules and destination law.

What sample gate exists?

If a sample is offered, record mass, container, residual analysis and the buyer method that will accept or reject it. This desk does not operate the laboratory or the molding press.

Use the masterbatch suppliers planner or return to the inquiry catalog when the field list is ready.

Request comparable manufacturer quotes

Send carrier, pigment load, quantity, bag or drum net content and the US receiving city. Producers are asked those fields only; mill output, lead time and a savings percentage are not invented here.
