When sending new items a copy of the invoice needs to be provided. This can either be in the form of an invoice received with an online purchase or a photo of an in store invoice. The invoice should include your name and that of the supplier, the value of the package and a description of the product. (The value of the product includes shipping and local tax charges).
A package valued above $75 is charged a tax of 17% by the Israeli tax authorities. In such an event, an Isareli citizen will need to provide a Teudat Zehut number and a non Israeli will need to provide a picture of the passport of the declarant.
