CAS attempts to honor claims whenever possible; however, certain restrictions apply. For instance, claims cannot be honored if items are missing because of failure to report a change of address or because a copy is lost or missing from your files.

When submitting a claim, identify the product and reason for the claim, and include the issue number, volume number, customer name, and CAS account number. (Your account number is located above your address on the mailing label and is printed on your subscription invoice.) This information will help us ensure fast and efficient service. Please refer to the table below to determine the claim period for your area.

To submit a claim you should contact CAS Customer Care or use this web-based form.

If you are a non-U.S.A. subscriber whose CAS products are being shipped to a U.S.A. freight forwarder (shipping agent or drop shipper) or subscription agent, please submit your claim within the same allowable claim period as designated for U.S.A. claims: 90 days from publication date plus the estimated delivery time of 3 to 6 weeks.

If you have your CAS subscriptions delivered to a freight forwarder, CAS is not responsible for final delivery from the freight forwarder to your organization.
