International shipping delivery times are dependent on which mail service is used and can take anywhere from a few days to several weeks for your package to be delivered.

Sending a shipment overseas is like sending yourself overseas: preparation is required. One of the most important steps in the process for either scenario is to determine what class to travel in to get there.

USPS International Shipping Update: HS Codes Required

As of September 1, 2025, the U.S. Postal Service will require all international commercial shipments to include a six-digit Harmonized System (HS) code on customs declarations for each item, regardless of mail class.

The HS code system, created by the World Customs Organization, is used by customs authorities worldwide to classify goods and assess tariffs. This update aligns USPS mailing standards with new Universal Postal Union (UPU) regulations, also taking effect Sept 1, requiring all member countries to enforce six-digit HS codes for commercial goods.
