A customs declaration is an official document that lists all details of imported or exported goods.
The person controlling the imported/exported goods fills out the customs declaration form.
It is necessary to input the information on the type of imported/exported items, their worth, purpose, as well as your contact information.
By filling out a customs declaration form and attaching it to an internationally-bound parcel, you are helping to ensure customs officials have all the information they need to process your arrival smoothly.
