If you are mailing any of these items, you must contact the United States Postal Service (USPS) or the Hawaii Department of Agriculture (HDOA) for specific instructions.
In general, the best way to mail items to Hawaii is to use a USPS flat-rate box. These boxes come in various sizes and shapes and are priced based on their size, not their weight. This makes it easy and convenient to ship items to Hawaii without worrying about the cost.
You can also use a private shipping carrier, such as FedEx or UPS, to mail items to Hawaii. However, these carriers typically charge more than the USPS. If you are shipping valuable or fragile items, you may want to purchase insurance.
