According to Japanese media reports, China’s ammonium sulfate export volume has exceeded 3 million tons in 2014, and the total annual export volume is expected to reach 4 million tons. As the main by-product of caprolactam (CPL), the output and accumulation of ammonium sulfate in China have been increasing year by year. In the past 5 years, the export volume of ammonium sulfate increased by 4 times. In 2014, Vietnam was the largest importer of ammonium sulfate in China with a total volume of 500,000 tons imported from January to October.
