Opinions

What are the key differences between reactive black and sulphur black in textile dyeing?

Cost dynamics also differ: sodium sulfide is cheap and used at roughly 1.2 times the dye weight, while reactive dyeing's salt and alkali consumption adds up. For bulk dark shades, sulphur black remains the most economical choice despite environmental handling costs.

How is the wastewater from Sulphur Black 1 production typically treated?

The recovered sodium thiosulfate has commercial value in photographic fixing, leather tanning, and as a dechlorinating agent. Producers should evaluate local market demand for these byproducts, as logistics costs can make recovery uneconomical if no nearby off-takers exist.

How does India's anti-dumping duty on Sulphur Black 1 affect Chinese exporters' pricing strategy?

Beyond duty avoidance, note that Indian domestic producer Atul Ltd. has repeatedly pushed for protection, signaling sustained pressure. Exporters should also watch for possible retroactive measures or expanded product scope in future reviews, which could affect even transshipped goods.

Overview

Sulphur Black 1 (C.I. Sulphur Black 1, CAS 1326-82-5) is a water-insoluble black dye powder produced by sulfurization of aromatic amines, phenols, or nitro compounds. It is one of only two true black dyes, alongside aniline black, and is widely used for cellulose fiber dyeing.

Textile dyeing: primary application for cotton and cellulosic fiber dyeing, offering good wash fastness and deep black shades.
Industrial: used in cotton blends and denim; available in powder and liquid forms, with liquid grades offering higher absorption and lower effluent treatment costs.
Environmental: liquid formulations reduce pollution by eliminating sodium sulfide use and minimizing wastewater impurities.

China is a major global producer and exporter of Sulphur Black 1, with a long production history and simple synthesis routes. The product remains cost-competitive despite competition from reactive dyes. In 2024, India imposed anti-dumping duties on Chinese Sulphur Black, with producer-specific rates ranging from 271 to 389 USD/tonne, reflecting ongoing trade tensions.

Key domestic producers:
Shandong Dyeriyarn Ecochem Co., Ltd. – major exporter subject to India anti-dumping duty.
Other Chinese producers – collectively face higher anti-dumping duties in India.
