The United States Postal Service handles 7.3 billion shipping and package deliveries annually, with millions requiring proper customs documentation. Getting your USPS customs forms right is essential for successful USPS international shipping — especially to military APO, FPO, and DPO addresses where incorrect paperwork can delay care packages to service members overseas.
This complete guide covers everything you need to know about USPS customs forms in 2026, including recent policy changes, required documentation, and how to avoid common mistakes that cause delays.
What Are USPS Customs Forms and Why Are They Required?
USPS customs forms are mandatory documentation that declares the contents, value, and purpose of international packages. These forms help customs officials in receiving countries process shipments, assess duties, and ensure compliance with import regulations.
All international packages require customs forms except First-Class Mail International letters and large envelopes under 15.994 ounces. Even packages sent to military APO (Army Post Office), FPO (Fleet Post Office), and DPO (Diplomatic Post Office) addresses — though treated as domestic mail — require specific customs documentation when crossing international borders.
