Customs Forms are required for all international mail weighing more than 16 oz. Customs forms help to identify the shipper’s name, address, and package contents for the destination country and FAA officials. There are two classes of customs forms. Parcel Post (all items over 4 pounds) and items valued over $400 require the 2976A multi-part customs form, which requires the use of a 2976E envelope. All other items can be mailed with the short 2976 customs form (items weighing over 4 pounds require 2976A customs form). Items not being sold or sent for resale should be described as “Educational Material, No Commercial Value” which will avoid customs fees on the receiver’s end. Do not detach the white “Post Office Copy” of the 2976 short form. A reminder: customs forms do not replace properly affixed address labels.
