Sulfuric acid prices rose sharply through the first half of 2026 before retreating from their mid-year peak as supply conditions loosened. Weak downstream demand has contributed to the easing, though the commodity remains a critical revenue buffer for copper smelters facing squeezed processing margins. The price trajectory reflects the interplay between by-product supply dynamics and broader industrial demand.
China's 98% smelting sulfuric acid price eased over the week as spot trading weakened and recovering supply added pressure. Elevated sulfur and metal ore costs provided partial support, but the market faces further downside as lower-priced regional supplies increase competitive pressure.
Naphthalene sulfonic acid, produced through the sulfonation of naphthalene with sulfuric acid, serves as a key intermediate in dyes, dispersants, tanning agents, and concrete superplasticizers, with end-use demand anchored in construction, textile, leather, and paper industries.
During H1 2026, the market experienced a broadly subdued pricing environment shaped by modest downstream demand and a well-supplied feedstock landscape. Across major Asian producing economies, naphthalene maintained a soft tone through much of the first half, easing cost pressures for manufacturers. Downstream sectors in the region, including concrete admixture producers and textile dye manufacturers, adopted a cautious purchasing stance. In European markets, sluggish construction activity and restrained industrial output tempered appetite for superplasticizers, while North American demand showed somewhat greater resilience from infrastructure-related activity, though broader macroeconomic uncertainties kept sentiment range-bound. Logistics conditions normalized meaningfully versus prior periods.
Analyst Insight
According to Procurement Resource, a modest H2 firming is plausible if construction activity strengthens seasonally.

Asia
Both the primary feedstocks of naphthalene sulphonic acid presented bleak sentiments in the first quarter of 2024, resulting in the southward movement of its prices. The slow offtakes from the downstream industries and the weak economic outlook of Asian countries also contributed significantly to keeping the naphthalene sulphonic acid prices on the lower end of the spectrum. However, after the Chinese New Year holiday season, the domestic manufacturers maintained their regular pace, which, in the absence of demand, only grew the inventories.
The market was further weakened by the loss of export profits due to the tensions at the Red Sea and limited inquiries from overseas industries amid challenging global trading dynamics.
Europe
Throughout the first quarter, the bearish tone of the downstream industries exerted a negative influence on the naphthalene sulphonic acid market and its pricing patterns. The lackluster development of industries was rooted in the broader economic challenges being faced by the European countries. Further, the carryover inventories were more than sufficient in catering to the minimal demand of the commodity while the sustained domestic production stressed the traders. The feedstock sectors also failed to extend any support to the market, and in view of these challenges, the naphthalene sulphonic acid prices took a downturn.
North America
The market sentiments of naphthalene sulphonic acid in North America were not much different from the Asian and European countries as the prices here, too, slid southwards. The market struggled with the existing stockpiles amid slow demand. The decline in feedstock coal and lowered the cost of production further dampened any hope of the manufacturers and traders.
The slow approach of the consumers was likely to be a result of trade disruption and increased transportation charges. The trading challenge stemmed from the disruption of the Red Sea route and lower water levels in the Panama Canal, adding additional pressure on the naphthalene sulphonic acid market and its price trend.
Naphthalene sulfonic acid is a pale-yellow crystalline powder, sulfonated derivative of naphthalene. The compound is highly soluble in water and is known for its strong acidic properties and surfactant properties. It serves as the key intermediate in the production of dyes, dispersing agents, and concrete superplasticizers. Its role in stabilizing emulsions and dispersing solids is widely employed in the textile, leather, oil, and gas industries.
