Prepare any document, letter or item that needs to be shipped to the Philippines. For regular airmail service using the United States Postal Service (USPS), you may either use your own envelope or box for your shipment or buy one directly at USPS. You may either buy and print the stamps, and also print the customs forms online or you may just buy the stamps and get copies of the forms when you are already sending the airmail at a USPS outlet.
Write your name and address, and the name and address of the recipient of the package in the Philippines. You may want to weigh it ahead of time so you have an idea how much it would cost. If it is a fragile or perishable item, place a note on the box. If your airmail includes many items, it is best to write them down before closing the package, because you will need this list for the customs form.
Go to your chosen USPS outlet to send the airmail. The weight of the airmail determines the amount you must pay. You will be given the customs forms, if you haven't prepared them ahead of time. The regular international airmail service of USPS is called "First Class Mail International."
Fill out the required forms, then pay the transaction fees. According to the USPS website, customs forms are not required on the following categories of mail: "non-dutiable First Class Mail International items that weigh less than 16 ounces; non-dutiable First Class Mail International items that weigh 16 ounces or more when they are tendered by a known mailer." For further information on what this means, see the Resources section below.
