Delrin® - Submitting your invoice


On August 21, 2023, DuPont de Nemours, Inc. (“DuPont”), the parent company of the Delrin® acetal business “Delrin® Business”1, announced a definitive agreement to sell an 80.1% ownership interest the Delrin® Business to TJC LP (TJC). Although a specific date for the intended transaction has not been announced, we are preparing the Delrin® Business to enable the potential closing of the intended transaction around year-end 2023 subject to customary closing conditions and regulatory approval.

Specifically, in anticipation of the intended transaction, DuPont is internally separating its Delrin® Business from DuPont’s other businesses (the “Internal Separation”) effective October 1, 2023, by updating its legal entity structure so that separate legal entities hold DuPont’s Delrin® Business. To be clear, until the closing of the intended transaction, the Delrin® Business is and continues to be, a business of DuPont, regardless of any changes as part of our Internal Separation.

This updated structure will be effective October 1, 2023, and will result in changes that will impact how you transact with us.

Effective October 1, 2023, the legal entity name, Tax Identification Numbers (TIN), and invoicing information for some legal entities are changing or are newly created. (Please note: some, not all, legal entities are impacted; others will have no changes.) Invoices related to impacted Purchase Orders need to be addressed to this changed or new address or email, unless otherwise determined by country laws and regulations (see more detailed instructions below).

In anticipation of the transaction, you may need to set up new Delrin® Business(es) as a customer in your system, as well as update the invoicing and tax information. (If you currently transact with the Delrin® Business and other DuPont businesses, please be sure to create a new account for the Delrin® Business and not replace the existing DuPont account.) The effective date to make these changes is October 1, 2023.

After September 30, 2023, we will be unable to process payments for invoices that are sent to the previous contacts. Failure to invoice the new legal entity will result in invoices being rejected for reasons of legal compliance.
