As an agreement to end the Iran War has yet to be reached and the logistical issues resulting from the closure of the Strait of Hormuz continue to mount, raw materials suppliers to the adhesives and sealants industry are raising their prices. Major adhesives and sealants manufacturers are responding with announcements of their own product price increases. Both adhesives and raw materials suppliers are tying the rising costs of their products to petrochemical constraints, tariffs, energy costs, logistics volatility, and the continued pressure on specialty chemical feedstocks.

In March, H.B. Fuller announced a global price adjustment across all product lines. The company cited broad-based constraints in the petrochemical industry affecting availability and raw material costs across the value chain. The company implemented "a minimum 10 percent price increase across all product lines globally, with significantly higher price adjustments for certain technologies and regions." H.B. Fuller stated that the increase would ensure continuity of supply and service. "Our teams are working diligently to keep customers supplied and supported, even as global markets remain fluid," said Celeste Mastin, president and chief executive officer at the company.

Henkel discussed increasing raw material costs in recent financial updates. In its 2026 outlook, the company said it expects direct materials costs to be in the “high single-digit percentage increase compared to the previous year’s average (previously: low single-digit percentage increase)”

On the raw materials side, Celanese recently announced broad price increases across its acetyl chain portfolio, including vinyl acetate monomer (VAM), EVA, emulsions, dispersions, and solvents used extensively in adhesives and sealants formulations. The company attributed the increases to rising costs and market pressures across global chemical supply chains. Oxea likewise announced price increases tied to rising raw material, energy, and logistics costs.

Earlier in the year, WACKER announced a price increase for its silicones product range. The company stated that the conflict in the Middle East led to significant disruption in global supply chains, resulting in significantly increased costs for energy, raw materials and logistics. In a press release about the increase, the company stated, “The current developments in the Middle East have led to significant distortions in the energy and raw materials markets worldwide. Due to this and to considerable disruptions to international trade routes prices for oil, natural gas, raw materials and logistics have risen palpably. WACKER’s global silicones business is affected by this development.”

Additionally, BASF announced a price increase of up to 30% on selected Home Care, Industrial & Institutional Cleaning (I&I), and Industrial Formulators products in North and South America in March. The company stated, “Given current market dynamics and the high volatility of cost increases, the validity of the price list will be reviewed regularly and communicated accordingly.”

Industry-wide indicators also suggest continuing inflationary pressure. U.S. Producer Price Index (PPI) data for adhesives and sealants manufacturing and related chemical feedstocks show elevated pricing levels compared with historical averages.
