Plastics manufacturing is a major part of the chemical industry, and some of the world's largest chemical companies have been involved since the earliest days, such as the industry leaders BASF and Dow Chemical.
In 2014, sales of the top fifty companies amounted to US$961,300,000,000. The firms came from some eighteen countries in total, with more than half of the companies on the list being headquartered in the US. Many of the top fifty plastics companies were concentrated in just three countries:
United States - 12
Japan - 8
Germany - 6
BASF was the world's largest chemical producer for the ninth year in a row.
Trade associations which represent the industry in the US include the American Chemistry Council.
