As a global corporation with manufacturing facilities around the world, Corning is reliant upon a vast network of suppliers. These relationships are built on our Values and our commitment to Sustainability. Suppliers are carefully selected and adhere to our Supplier Code of Conduct to maintain integrity throughout the supply chain. 

To protect your interest and to prevent misunderstandings, Corning Global Supply Management is the only organization authorized to commit Corning Incorporated to a purchasing agreement. Our purchase order is your assurance that Corning Incorporated stands behind the purchase and that your invoice will be paid in accordance with the agreed upon terms.

Corning Incorporated requires full compliance with U.S. Customs law. Whenever Corning is the U.S. Importer of Record, we enlist the assistance of our foreign suppliers to ensure full compliance. Complete instructions for all suppliers regarding compliance with U.S. import requirements can be found on the Corning Routing Guide page.
