Buyer resources / a clearer first inquiry

What to include in a masterbatch inquiry.

Start with your base resin, processing method, end application and color or specification target. Add the quantities and documents you want reviewed. If a detail is unknown, say so: a clear gap is more useful than an assumed specification.

01 / the essentials

Describe the final part or film.

Base resinThe resin used for the final part or film, with a grade if known. State a requested masterbatch carrier separately.

Processing methodFor example, injection molding, blown film, blow molding or extrusion. Include relevant production conditions you already have.

End applicationDescribe the finished product and intended use. Add part or film thickness where it is relevant to the requested appearance or performance.

Your roleTell us whether you are the processor, brand owner, distributor or sourcing representative, and which technical information you can confirm.

02 / choose your request

Separate the requirements that need review.

Standard-grade inquiryState known composition targets, pigment content, carrier preference and any required filler inclusion or exclusion. Ask for a matching-grade review rather than assuming a grade fits.

Custom colorProvide a color code and its reference system, or describe the physical sample, plaque or swatch available. Tell us whether a photo or sample has actually been supplied.

Functional appearanceDescribe the target effect, such as diffusion or a dead-front appearance, and provide any defined measurements, test conditions and tolerance for technical review.

Regulatory or document requestIdentify the target market, end use and applicable requirement if known. Specify what the requested document must cover.

Common clarification points

Small details that prevent another round of questions.

These checks help keep the discussion tied to your intended application.

What does a percentage in my specification mean?

Label each percentage with its property. State whether it refers to pigment content, addition rate, transmission, haze or another measurement. For a measured property, include the method and conditions if specified. A percentage on its own leaves the request ambiguous.

Can I start with a product photo?

Yes, you can use a photo to explain the initial request. State whether a physical reference or approved color code is also available. The reference and acceptance criteria still need to be agreed for the project.

What should I include in a food-contact document request?

State the intended market, final application and standard or customer requirement you want reviewed. If these are not confirmed, identify the gap. Requesting a document does not establish that a particular grade or final application is compliant.

Do I need a quotation immediately?

Tell us whether you want a technical review, a matching-grade discussion, a TDS, sample availability or a quotation. For commercial review, add the order quantity, delivery destination and requested timing. Sample quantity and production order quantity should be separate.

Send a useful starting brief, even if some fields are still open.
