Import Dye — Buy in Bulk from Supplier in China

Syntop Chemical Co., Ltd, based in Tianjin, China, supplies industrial dyes for the textile, paper, pharmaceutical and leather sectors. Their catalogue includes Reactive Brilliant Blue, Sulfur Black, Titanium Dioxide, Zinc Chrome Yellow, Oil Soluble Blue and Vat Yellow 3RT. Each product is formulated for high colour strength and stability in the intended application. The company advertises these dyestuffs as suitable for large‑scale manufacturing processes.

In the dye industry, purity levels of 85 % or higher are typical, ensuring consistent shade matching and low impurity content. Most powdered dyes dissolve at about 5 g per litre of water at 25 °C, allowing easy batch preparation. They remain stable across a pH range of 2 to 10, which covers most textile and paper processing conditions. Particle sizes usually fall between 5 and 20 µm, facilitating uniform dispersion in finishing baths.

Textile mills, paper producers, pharmaceutical manufacturers and leather tanneries are the primary buyers of these chemicals. Syntop offers bulk shipments, commonly packed in 25 kg HDPE drums, with FOB terms from Tianjin port. The listing does not provide a minimum order quantity or lead‑time, so importers should confirm those details directly with the supplier before placing an order.

Syntop Chemical Co., Ltd operates from Hesheng International Plaza in the Binhai New Area of Tianjin, China. The supplier holds a harbor‑level trust tier on the platform, though its response rate is currently recorded as 0 %. The listed address confirms a physical presence in a major industrial zone, which can be verified through local business registries.

The company focuses on supplying chemical dyestuffs to a range of downstream industries, including textiles, paper, pharmaceuticals and leather processing. Its product range is limited to the colourants mentioned in the source description, and no additional certifications or capacity figures are provided in the listing.
