FAQ

Common Sourcing Questions

Common Sourcing Questions in Pigment & Dye

What certifications should I check when sourcing inorganic pigments for industrial use?

When purchasing inorganic pigments, prioritize certifications like ISO 9001 for quality management and CE marking for EU safety compliance, ensuring product reliability. Verify MOQ (typically 500kg+) and request lab samples for color consistency testing before bulk orders. Custom packaging in sealed, moisture-resistant bags helps prevent degradation during sea freight. Always confirm supplier adherence to these standards to avoid delays and ensure smooth procurement.

How can I customize reactive dyes for specific textile applications?

To customize reactive dyes, provide detailed specifications like fiber type and color fastness requirements to your supplier. The process includes initial sampling (small batches for testing), with MOQ starting at 200kg. Ensure certifications such as Oeko-Tex for eco-safety. Lead times for custom formulations are 3-5 weeks, including dye stability checks. Opt for vacuum-sealed packaging to maintain quality during international shipping.

What is the typical MOQ for vat dyes in large-scale orders?

For vat dyes, MOQ often ranges from 300kg to 1,000kg depending on the supplier and dye concentration. Confirm ISO 9001 certification for consistent quality and request pre-shipment samples to verify shade accuracy. Customization options include adjusting solubility for specific applications. Packaging in durable, UV-resistant containers ensures safe transport. Plan for 4-6 week lead times to accommodate testing and bulk production.

Are acid dyes compliant with international safety standards for wool dyeing?

Yes, acid dyes should carry certifications like REACH and CE for safety in wool and nylon applications. Check supplier credentials for ISO 9001 to guarantee batch consistency. MOQ starts at 150kg, with sampling available for pH and colorfastness tests. Custom formulations require 2-4 weeks for development. Use airtight packaging to prevent moisture damage during transit, and select FCL shipping for cost-efficiency.

Can basic dyes be tailored for enhanced color fastness in paper manufacturing?

Basic dyes can be customized for improved color fastness by specifying parameters like lightfastness and pH tolerance. Suppliers typically offer MOQ from 100kg, with sampling to validate performance. Look for CE and ISO 9001 certifications to ensure quality. Lead times for custom batches are 3-4 weeks. Packaging in moisture-barrier bags protects against humidity during shipping, and air freight is recommended for urgent orders.

What packaging solutions prevent contamination for organic pigments during global shipment?

For organic pigments, use multi-layered, anti-static packaging such as aluminum-lined bags to avoid contamination and oxidation. Suppliers should hold ISO 9001 and CE certifications for reliability. MOQ starts at 250kg, with samples for purity testing. Customization for particle size or dispersion adds 2-3 weeks to lead times. Opt for temperature-controlled shipping containers to maintain stability, especially for long hauls.

How is quality maintained for sulphur dyes during international transport?

Quality for sulphur dyes is preserved through certified packaging like corrosion-resistant drums with desiccants to prevent moisture absorption. Ensure suppliers have ISO 9001 and REACH compliance. MOQ is usually 400kg+, and request samples for sulfur content verification. Lead times average 4 weeks. Use refrigerated shipping for sensitive batches, and confirm insurance coverage for transit risks to safeguard your investment.

What lead times should I expect for custom disperse dyes in synthetic fiber applications?

Lead times for custom disperse dyes range from 4 to 6 weeks, including formulation, sampling, and stability testing for synthetic fibers. Confirm MOQ (e.g., 300kg) and supplier certifications like Oeko-Tex and ISO 9001. Sampling is crucial for color match approval. Packaging in UV-protected containers prevents fading during transit. Plan for sea freight with tracking to manage costs and timelines effectively.
