Air Liquide recently completed its acquisition of Airgas and the two companies have come
together as one industry-leading business.

Effective April 3, 2017, several Air Liquide businesses that were integrated into Airgas in 2016 will now transition to Airgas’ SAP enterprise system. These businesses include Air Liquide’s legacy ASUs and Large On-Sites, Industrial Gas Services, and Oil and Gas. Our goal is to make this transition seamless to you, our valued customers. As part of this transition, you will need an Airgas USA, LLC W-9 with the Airgas USA, LLC tax ID number. Please download this W-9 form and keep it for your records.

If you have any questions, please contact Airgas by phone at 866-935-3370.
