Abstract: Analyzed in the paper are the export/import volumes，average prices and varieties of China’s steel tubes from 2000 to 2017.Also introduced in details are the trade remedies of foreign countries against China’s steel tube sector，as well as Section 232 Investigation on Steel and Aluminum released by U.S.Department of Commerce.Based on the analysis，it is concluded that China’s steel tube export condition in 2017 is better than that in 2016.China’s steel tube import volumes have declined dramatically over the recent years to only 0.51%of the overall steel tube production.Global economic situation is generally improving，which is good for export；but China’s steel tube export countries and regions are limited because of the influence of international trade protectionism.
