Among them, the German chemical giant BASF once again ranked first in the world's chemical industry top 50 with US$70.5 billion in chemical product sales. This is the company's sixth consecutive year ranking. The vast majority of the company's profits do not come from the chemicals business but are contributed by its Wintershaw oil and natural gas exploration business. Dow again became the second largest chemical company in the world. The company’s sales in 2008 reached US$58 billion, an increase of 7.5% over the previous year; however, its profit index fell sharply by 44.1% from the previous year to US$2.2 billion. In the third place is still the British Ineos Group, its sales revenue in 2008 was 47 billion US dollars, a huge contribution to the refining business. Shell's ranking was relegated from the third in the previous year to No. 11 because this year's statistics deducted sales revenue from its non-chemical business.
