SQM entered the industrial chemical business over 30 years ago, producing and selling industrial nitrates, which are used as raw materials in a great number of production processes. SQM also sells boric acid and industrial-grade potassium chloride.

The high-grade nitrates are used in a wide variety of applications that are a part of everyday life. From manufacturing glass to explosives for mining and civil works to treating metals, this broad range of applications, combined with a customer base that is spread all over the globe, affords SQM considerable diversification in its sales.
