Nitrosylsulfuric Acid prices in Germany, the highest-cost reporting region, posted a net gain of 7.3% in H1 2026, climbing from USD 1.164/KG in Q1 2026 to USD 1.249/KG in Q2 as sulphuric acid feedstock cost firming and recovering dye intermediate procurement from textile finishing manufacturers sustained buying through the season. Globally, the average rose from USD 0.882/KG in Q1 to USD 0.946/KG in Q2, a 7.3% gain extending the Q4 2025 recovery trend. For H2 2026, a global average of USD 0.95-1.07/KG is expected, with continued support from dye sector output recovery and sulphuric acid input cost firming in major producing markets.
Nitrosylsulfuric Acid (NSA), also known as chamber crystals or nitrosyl sulfuric acid, is produced by absorbing nitrogen oxides in concentrated sulphuric acid to yield a pale yellowish crystalline solid with the molecular formula NOHSO4, requiring controlled absorption conditions and temperature management to meet technical grade purity specifications for downstream synthesis applications. The largest pull comes from dye manufacturing, where NSA serves as a diazotization agent in the preparation of azo and direct dyes for textile, leather, and paper colouring applications, converting primary aromatic amines into diazonium salt reaction intermediates used across the textile finishing and printing supply chain. Pharmaceutical intermediate synthesis, where NSA supports diazotization steps in active pharmaceutical ingredient production, and specialty organic synthesis for fine chemical and laboratory reagent applications consume further volumes alongside agrochemical intermediate production. Specialty pigment synthesis for coatings and printing ink formulations adds a consistent smaller demand stream. Sulphuric acid input cost, nitrogen oxide availability, dye intermediate production output, and textile sector capacity utilisation all feed into the price.
The balance of supply and demand for Nitrosylsulfuric Acid through H2 2026 leans moderately firm. Recovering dye intermediate production in Asian textile centres maintained buying. Sulphuric acid input cost firming supported the production floor across European and Asian producers.
The main upside risk is a sulphuric acid cost spike from smelter sulphur dioxide supply tightening, which would raise NSA production economics above the forecast range. The main downside risk is a weaker-than-expected recovery in textile finishing demand, which could ease dye intermediate procurement and soften buying interest.

Dye manufacturing takes the largest share globally. NSA serves as a diazotization agent in the synthesis of azo and direct dyes for textile, leather, and paper colouring. Pharmaceutical intermediate synthesis and specialty organic synthesis for fine chemicals and agrochemical intermediates also consume significant volumes.
The Q2 2026 average was USD 1.036/KG in the United States, USD 0.695/KG in China, USD 1.249/KG in Germany, and USD 0.965/KG in India. Germany carries the highest cost due to energy and sulphuric acid input premiums.
The global average rose from USD 0.882/KG in Q1 to USD 0.946/KG in Q2, a gain of about 7.3%. Recovering dye intermediate procurement and firmer sulphuric acid feedstock costs drove the Q2 recovery from the seasonal Q1 dip.
Seasonal procurement softness in pharmaceutical and dye intermediate applications eased buying urgency. Buyers drew down contracted inventory before the Q2 restocking season, softening the market to USD 0.882/KG before the Q2 recovery.
The global average is expected in the USD 0.95 to 1.07/KG range for H2 2026, with support from recovering dye sector output and sulphuric acid input cost firming across Asian and European producing markets.
Germany holds the highest cost on energy and sulphuric acid input premiums, the United States and India hold a firm middle, and China prices lowest on large domestic production capacity and lower energy costs.
