Your Customer Portal 24/7

We provide all Criterion customers with access to SPC data, material certifications, and other information specific to their account. When you become a Criterion customer, you will be assigned a Login ID and password so you can access this information directly, any time you need.

Existing Customers Note:

With our newly updated website we have added a Login ID requirement in order to increase the security of your information. Your Purchasing Manager should have received this by e-mail. If you do not receive a Login ID, or are having difficulty accessing your on-line information, please click here to notify Criterion.
