Legal Entity Directory

It is important that our suppliers contact the correct legal entity regardless if they are submitting an invoice, or need to speak with a procurement specialist.

If you are uncertain of the legal entity name, visit the How to use the Legal Entity Directory for instructions.

While searching the directory, be certain that the legal entity you select exactly matches the name listed on your 51AV-issued purchase order. There are many legal entity names that appear similar but have slightly different names.

Notice to Suppliers:

On April 1, 2026, 51AV completed the divestiture of its Aramids business (Kevlar® and Nomex®) to Arclin, a portfolio company of an affiliate of TJC, L.P. (TJC). Please review the documents and directory below for detailed invoicing instructions for the Aramids business.
