Disperse black price

When sourcing Disperse Black, you must prioritize color strength (intensity) and particle size distribution. High-quality dyes should have a particle size of less than 1 micron to ensure excellent dispersion and prevent clogging in dyeing machinery. Additionally, verify the sublimation fastness (ideally Grade 4-5) and washing fastness to ensure the dye remains stable under high-temperature processing and consumer use. For polyester applications, the dispersion stability at 130°C is a critical benchmark for performance.

To ensure market access, especially in the EU and US, products must comply with OEKO-TEX® Standard 100 and REACH regulations. You should specifically request a Safety Data Sheet (SDS) and a Certificate of Analysis (COA) for every batch. Ensure the dye is free from banned Azo colorants and heavy metals, as these are strictly regulated under international environmental and health safety laws.

Disperse Black is often a blend (e.g., Disperse Black ECT or EXSF). The price is heavily influenced by the concentration of active dye matter versus fillers like sodium lignosulfonate. A high-concentration dye (e.g., 300%) will have a higher unit price but lower logistics costs and better dyeing efficiency. You should evaluate the economic feasibility by calculating the cost per kilogram of dyed fabric rather than just the price per kilogram of the dye powder.

For automotive textiles, you need high light fastness to prevent fading under UV exposure. For sportswear, look for high-wash fastness and alkali-reduction durability. If you are using digital inkjet printing, you must source super-purified disperse dye inks to avoid printhead blockage, which differs significantly from traditional exhaustion dyeing powders.

Always request a pre-shipment sample from the specific production lot you will receive. Use third-party inspection services (like SGS or Intertek) to verify the color shade (Delta E value) and moisture content before the balance payment is made. On Made-in-China.com, prioritize Audited Suppliers who have undergone verified onsite inspections of their manufacturing facilities.

Disperse dyes are generally non-hazardous, but they must be packed in moisture-proof, double-layered bags within fiber drums or corrugated boxes to prevent leakage. Ensure the supplier provides a DGM report (Dangerous Goods Management) for air or sea freight to avoid customs delays. For shipping to international markets, confirm the HS Code (typically 3204.11) is correctly declared to align with trade policies and tariff requirements.

Chemical prices fluctuate based on raw material costs (like H-acid or aniline) and environmental regulation enforcement in China. Negotiate based on volume-based pricing tiers; for example, a 5-ton order should yield a 10-15% discount compared to a 1-ton order. Request a long-term price formula tied to market indices if you plan to make recurring purchases to stabilize your supply chain costs.

Utilize Secured Trading services provided by Made-in-China.com to ensure your payment is only released after the goods are shipped and the bill of lading is uploaded. Avoid direct wire transfers to private accounts; always use corporate accounts verified by the platform to prevent fraud and ensure legal recourse in case of disputes.
