Diamino Sulfanilide Prices, Demand and Supply Overview

Diamino Sulfanilide prices in Germany, the highest-cost reporting region, rose 7.0% in H1 2026, climbing from USD 13.607/KG in Q1 to USD 14.559/KG in Q2 as aromatic amine feedstock cost firming and recovering dye intermediate procurement from reactive and direct dye manufacturers reversed two consecutive quarterly declines through Q3 and Q4 2025. Globally, the average rose from USD 10.387/KG in Q1 to USD 11.114/KG in Q2, a 7.0% gain. For H2 2026, a global average of USD 11.2-12.6/KG is expected, with continued support from dye sector output recovery and aromatic amine feedstock cost firming across Asian and European producing markets.

Diamino Sulfanilide (DAS), commercially available as 4,4’-diaminodiphenylsulfone (DADPS) and related diaminoarylsulfone derivatives, is produced by catalytic hydrogenation or chemical reduction using sodium sulphide or iron powder of the corresponding dinitro precursor under controlled temperature and pH conditions, yielding a pale yellow to off-white crystalline solid with two primary aromatic amine groups that enable diazotization and coupling reactions in dye synthesis. Commercial production requires precise control of reduction conditions, product isolation by filtration, and purification by recrystallisation to meet the amine purity specifications required for consistent downstream dye colour strength. The largest pull comes from reactive and direct dye manufacturing, where the bifunctional diamine structure enables synthesis of bisazo and polyfunctional dye architectures for textile, leather, and paper colouring applications with broad colour gamut. Pharmaceutical intermediate synthesis for sulphonamide-type active ingredient production, specialty epoxy and polyimide resin curing agent applications, and polymer additive use add further demand. Aromatic amine feedstock cost, reductant availability, dye manufacturing output, and textile sector capacity utilisation all feed into the price.

Diamino Sulfanilide Price Forecast for 2026

The balance of supply and demand for Diamino Sulfanilide through H2 2026 leans moderately firm. Recovering reactive and direct dye manufacturing output in Asian textile centres maintained procurement. Aromatic amine feedstock cost firming supported the production floor across European and Asian producers.

The main upside risk is an aromatic amine or dinitro precursor cost spike raising production economics above the forecast range. The main downside risk is weaker-than-expected dye sector recovery or textile finishing demand softness extending the seasonal procurement dip.

Region 2026 Price Range (USD/KG) Outlook
Global Average 11.2 - 12.6 Dye sector recovery and amine feedstock support
United States 12.2 - 13.7 Specialty synthesis demand holds firm buying
China 8.5 - 9.6 Large capacity keeps China most affordable
Germany 14.6 - 16.5 Energy and feedstock costs maintain premium
India 11.0 - 12.4 Dye export demand supports firm middle

Key Questions Answered in the Report

Reactive and direct dye manufacturing takes the largest share globally. The bifunctional diamine structure of DAS enables bisazo and polyfunctional dye synthesis for textile, leather, and paper colouring. Pharmaceutical intermediate synthesis, specialty epoxy and polyimide resin curing agent applications, and polymer additive use also consume significant volumes.

The Q2 2026 average was USD 12.114/KG in the United States, USD 8.391/KG in China, USD 14.559/KG in Germany, and USD 10.947/KG in India. Germany carries the highest cost due to energy and aromatic amine feedstock input premiums.

The global average rose from USD 10.387/KG in Q1 to USD 11.114/KG in Q2, a gain of about 7.0%. Recovering dye intermediate procurement and firmer aromatic amine feedstock costs drove the H1 2026 rebound from the two-quarter Q3-Q4 2025 decline.

Seasonal procurement softness in reactive dye manufacturing eased buying urgency through both quarters. Aromatic amine feedstock cost moderation reduced the production floor. Inventory drawdown ahead of H1 2026 restocking extended the two-quarter softening.

The global average is expected in the USD 11.2 to 12.6/KG range for H2 2026, with support from dye sector output recovery, aromatic amine feedstock cost firming, and recovering textile sector capacity utilisation across Asian and European markets.

Germany holds the highest cost on energy and aromatic amine feedstock input premiums. The United States and India hold a firm middle, and China prices lowest on large domestic production capacity and lower energy and feedstock costs.

This report is updated monthly. For real-time pricing intelligence, contact the Expert Market Research team directly.

Prices respond mainly to aromatic amine feedstock cost, dinitro precursor availability, reactive and direct dye sector procurement cycles, and downstream textile finishing and pharmaceutical intermediate demand seasonality.

China holds the largest production capacity, followed by India and European producers. Any aromatic amine feedstock cost shift or dye sector demand change ripples across all regional markets.

Buyers can use quarterly trends and forecasts to time contracts around dye sector procurement cycles, monitor aromatic amine feedstock cost as the primary production floor signal, and build forward coverage ahead of the Q1 and Q2 2026-style recovery phases.
