Tax certificates

State Sales and Use Tax Certificates / Federal Excise Tax Certificates

Please review the tax certificates available on this page before submitting a request.

If the certificate you need is not available, LYB employees may request a certificate through the Tax Certificate Power App (Tax Certificate and Disputes - Power Apps).

If you are not an LYB employee, please contact your LYB business contact, who can submit the request on your behalf. Your LYB business contact is typically the buyer or procurement representative listed on your purchase order, or the LYB employee who requested your goods or services.
