3) Special Conditions for Importing & Exporting Isocyanates
Isocyanates import volume into Iran
To supply domestic polyurethane and foam industries, Iran’s isocyanates imports reach thousands of tons annually. Volumes depend on industrial demand growth and polyurethane-related production. According to official customs data, more than 20 thousand tons of isocyanates are imported into Iran each year.
Exports of isocyanates from Iran are very limited because most of these materials are consumed domestically; direct imports predominantly come from major producers such as China, Germany, and South Korea.
4) Global Players & Isocyanates Market Flow
China, Germany, the United States, Japan, and South Korea are among the largest producers/exporters. With advanced technology and high capacity, they play a pivotal role in global supply. China is the largest producer/exporter, a key source for both developing and industrialized countries. Germany and the U.S., emphasizing advanced technology and quality, also hold major export shares.
Developing and industrial countries are major importers due to high demand for polyurethane-based products and foams. Notable importers include India, Türkiye, Brazil, Mexico, and Iran—driven by growth in automotive, construction, and home appliance sectors. Iran, due to strong domestic demand, is a key importer in the region.
Because of wide industrial applications, market value is substantial. It is estimated that the global isocyanates market will reach around 50 billion USD by 2027. Growth is fueled by demand from automotive, furniture, construction, and other polyurethane-related industries.
