Supply notice

USG is discontinuing this product

USG Corporation is phasing out its entire Industrial Products range, which is made at its Southard plant in Oklahoma. USG has confirmed these products will not be manufactured at any other site, and it is no longer accepting orders. The plant closes in November 2026.

USG has put the decision down to the escalating cost and complexity of mining and manufacturing the range, which relies on a highly specialised rock source that has become harder to extract.

Our stock has now sold out and we are unable to reorder.

We are currently looking to source alternatives for the future. Any updates will be posted on this page.

Updated 19/08/2026. The plant closure was reported by
Global Gypsum.
