Sourcing Organic Pigments
Colour-material enquiries should identify the target chemistry and the buyer’s substrate or processing application. Include the relevant colour and quality evaluation criteria so that potential supply options can be compared on a consistent basis.
For organic pigments, define colour identity, substrate and the particle, dispersion or performance tests used for application approval.
Include in your enquiry
- Chemical or colour-index identity and intended substrate
- Required assay, colour characteristics and relevant physical properties
- Evaluation quantity, packaging and end-use documentation

Explore technical profile03 / Better enquiries, clearer decisions
A useful enquiry starts with the right details.
Whether you are evaluating a synthetic building block or planning an industrial purchase, a shared specification helps both teams assess the same material.
Prepare my enquirySet the quality requirements
Share your target assay, test method and limits for critical impurities, water or residual solvents. Attach your specification if available.
Plan the supply request
State the quantity, preferred packaging, destination and required delivery date. Ask for the quotation and supporting documents to be reviewed together.
04 / Sourcing questions
Before you enquire.
How do I find a chemical by CAS number?
Enter the CAS number in the catalogue search. You can also search by English or Chinese name, synonyms or molecular formula where recorded. Open the product detail page to check its identity and category before sending an enquiry.
Does a catalogue listing mean the material is in stock?
A catalogue entry identifies a material within our sourcing portfolio. Availability, price, minimum order quantity, grade and delivery schedule are confirmed for each enquiry. The catalogue does not publish live stock or a fixed commercial offer.
Can I request a COA, SDS or specification?
List the documents required by your team when submitting an enquiry. Ask for the current safety data sheet, a suitable specification and relevant analytical evidence. Document availability and the applicable batch must be confirmed for the proposed supply.
What if I cannot find my product?
Send a sourcing enquiry with the product name, CAS number and target quantity. Include the intended application and any essential quality requirements so that the team can assess your request.
