The total volume of imports to the U.S. started to fall off in November of 2017 and fell to below 100 million KGs in mid-2018 before starting to recover in both weight and number of shipments. The largest supplier has been China, with Thailand and India distant second and third. Imports from China have been slowed by U.S. trade negotiations and the fact that domestic preference has remained strong. Demand is still steady at around 6.5%, and there remains plenty of domestic capacity should imports from China erode further.


The American Supply Association (ASA) and its Industrial Piping Division (IPD) is the national organization serving wholesaler-distributors and their suppliers in the industrial and mechanical pipe-valve-fitting industry.  As a powerful alliance of channel partners, we provide a forum for your upstream trading partners to exchange critical information and address key issues.

In particular, ASA’s IPD members constantly check the pulse of the materials and commodities they proudly supply to you.  ASA’s IPD members are knowledgeable industry leaders, and those who volunteer their service on the IPD Executive Council compile and prepare the IPD Commodity Reports.  The Reports contain some of the most current and qualified market data and information available from the industry’s leading manufacturers and distributors about emerging trends and other price-influencing actions and events.
