Effective on orders placed after September 16, 2021, Interface will permanently increase its U.S. market prices 5-7% for all carpet tile products and 10% for adhesives. Because of the extreme rise in shipping container costs, the company said it is also adding a temporary $0.25 surcharge per square foot to all LVT orders and a $0.10 per square foot surcharge to all nora rubber product orders. The shipping surcharge will be reduced or discontinued when freight costs moderate.
