Naphthalene is a polycyclic aromatic hydrocarbon recovered from coal tar distillation or as a byproduct of petroleum refining. The largest demand pull comes from concrete superplasticiser production via naphthalene sulphonate, followed by phthalic anhydride synthesis, and dye and pigment intermediate manufacturing. Coal tar availability, concrete and infrastructure sector demand, and regional processing capacity all feed into the price.
Global naphthalene prices tracked close to the USD 0.52 to USD 0.66 per KG range projected for 2026, as superplasticizer demand and coal tar costs supported the tone. US prices averaged USD 0.60 per KG in Q1 2026, up 7.1 percent from Q4 2025, as firmer coal tar availability from recovering steel production and growing concrete superplasticizer demand supported prices while phthalic anhydride sector restocking provided additional buying support. China's large coal tar capacity kept it the most affordable source, while Germany remained the highest-cost reporting region.
Naphthalene prices held a firm tone through August 2026, tracking close to the Q1 2026 levels across all tracked regions, as firmer coal tar availability and growing concrete superplasticiser demand continued to support the market.
The balance of supply and demand for naphthalene through the rest of 2026 leans moderately firm. Coal tar naphthalene supply firmed with recovering steel and coke production in major markets. Infrastructure construction demand for naphthalene sulphonate superplasticizers is growing with government investment programmes.
The main upside risk is accelerating infrastructure construction demand alongside steel production recovery that limits coal tar availability. The main downside risk is petroleum-route naphthalene capacity additions that expand supply and moderate the price recovery.

| Global Average | 0.52 - 0.66 | Superplasticizer demand and coal tar costs support tone |
| United States | 0.56 - 0.70 | Steady concrete and phthalic demand keeps it firm |
| China | 0.32 - 0.46 | Large coal tar capacity keeps it the most affordable source |
| Germany | 0.72 - 0.86 | High processing and energy costs keep it the most expensive |
| India | 0.52 - 0.66 | Growing infrastructure concrete demand holds a firm middle |

Naphthalene sulphonate superplasticisers for high-performance concrete take the largest share. Phthalic anhydride production for plasticizers and alkyd resins, dye intermediate synthesis, insect repellent applications, and leather tanning auxiliaries also consume significant volumes globally.
The Q1 2026 average was USD 0.60/KG in the United States, USD 0.34/KG in China, USD 0.77/KG in Germany, and USD 0.56/KG in India. Germany remains the highest-priced market.
The global average rose from USD 0.508/KG in Q1 2025 to about USD 0.530/KG in Q4, a full-year gain of around 4.3%. A brief Q2 softening was followed by a consistent recovery on coal tar supply firming and concrete demand growth.
Steel and coke production softness reduced coal tar byproduct availability, but soft concrete superplasticiser demand in the early construction season outweighed the supply constraint, pressing prices lower before the H2 infrastructure demand recovery.
The global average is expected in the USD 0.52 to 0.66/KG range for the rest of 2026, with continued firming as infrastructure investment expands concrete superplasticiser demand and steel production recovery supports coal tar supply economics.
Germany sits highest on energy and coal tar processing costs, the United States and India hold a firm middle on concrete and phthalic demand, and China prices lowest on large domestic coal tar distillation capacity.

Prices respond mainly to coal tar availability from steel and coke production, concrete superplasticiser demand, and phthalic anhydride sector activity. Steel production cycles and infrastructure investment programmes are key near-term signals.
Asia Pacific leads with China holding the largest coal tar distillation capacity, followed by Europe and North America. Any steel or coke production change ripples across naphthalene markets within one to two quarters.
Buyers can use quarterly trends and forecasts to time superplasticiser and phthalic contracts, build cover when steel production signals coal tar tightening, and monitor infrastructure investment cycles as the primary demand signal.
