The chemical industry has been slow to get online for sales, but U.S. chemical sales have gained a foothold in ecommerce in recent years, industry experts said in a recent webinar presented by Knowde, a chemicals industry B2B online marketplace. The presentation, featuring speakers from chemicals giant DuPont, global consultants Deloitte and Knowde, noted a compound annual growth rate (CAGR) of 3.7% in U.S. chemical industry B2B ecommerce sales on company websites and third-party marketplaces between 2017 and 2020, resulting in $27.8 billion in online sales projected for 2020, according to figures from Deloitte. With worldwide chemical industry sales of $4.1 trillion, however, there is plenty of room for the industry to grow online.
