International Supplier Information
International suppliers have separate approval requirements dependent on their Visa type, reason for payment and location where service/activity will be performed.
Homeland Security (IRS, U.S. Immigration, and Department of Treasury) dictates taxation rules, treaty eligibility, and work authorizations that we must abide by when paying foreign individuals/entities.
All international suppliers will be paid via wire transfer. Wire information will be collected at the time of registration. International suppliers should have the appropriate tax documentation current and readily available:
-
-
- Form W-8BEN, Certificate of Foreign Status of Beneficial Owner for United States Tax Withholding.
- W-8BEN-E, Certificate of Status of Beneficial Owner for United States Tax Withholding (Entity).
- Form W-8ECI, Certificate of Foreign Person's Claim That Income Is Effectively Connected with the Conduct of a Trade or Business in the United States.
- Form W-8EXP, Certificate of Foreign Government or Other Foreign Organization for United States Tax Withholding.
- Form W-8IMY, Certificate of Foreign Intermediary, Foreign Flow-Through Entity, or Certain U.S. Branches for United States Tax Withholding.

When I log back into my account, I can’t find my Clemson Registration, where is it?
When you log into your Jaggaer portal, you will click on the link that says, “Manage customer registration”, and then click on Clemson Registration. Do you have multiple Jaggaer profiles?

I am a current supplier with Clemson, but I did not receive the email to update my registration. What do I do?
The invitation email was sent to the person who set up your Clemson supplier registration. If that person is no longer with your company and you do not have access to that email, then you will need to be added to the account. You can reach out to Jaggaer customer service at 800-233-1121 for assistance with being added as a user on the supplier registration. For details on which email this request was sent to, please reach out to supplier@clemson.edu.

Under the address tab of your registration, you can provide your PO distribution on your Fulfillment address with either your email address or fax number.

I entered my password and received a One-Time Verification Code. However, when I entered the code, it said it was invalid.
Sometimes, multiple codes may be sent in a short period. Make sure you are using the most recent code that was sent to your email to sign in. If you’re unsure, wait for a new code and try again using that one.
-
Can I use my phone to register?
No, you must use a desktop or laptop to register due to errors that occur on mobile devices.
Parking
All suppliers must comply with University parking regulations. Suppliers, service contractors and construction workers must obtain a visitors permit from Parking and Transportation Services before attending a scheduled pre-bid meeting or a required site visit for bidding purposes.
Tax Information
Clemson University is not tax-exempt, with a few exceptions.
