The tariff percentages used by the Landed cost calculator when a delivery rate is configured for PDDP (Postal Delivered Duty Paid) have been updated.

Previously, the PDDP tariff table used country-specific percentages based on the former reciprocal tariff schedule. Following recent changes to U.S. tariff policy and the replacement of the reciprocal tariff regime, a temporary global surcharge of 10% now applies to most imports into the United States.

As a result:

• All country-specific tariff percentages in the PDDP tariff table have been replaced with a flat 10% rate
• The United Kingdom and All other countries (default) entries remain at 10% but are now aligned with the global rule
• The logic for HS code exclusions (including cultural works and Section 232 steel categories) remains unchanged

The previous country-by-country percentages were based on a tariff structure that is no longer in force. Continuing to use those values would have resulted in inaccurate customs & duties calculations at checkout for merchants shipping to the United States using postal carriers.

This update ensures that:

• Customs & duties estimates shown to visitors reflect the currently applied U.S. surcharge
• Merchants using PDDP are not over- or under-charging based on outdated tariff percentages
• The Landed cost calculator remains aligned with current U.S. import policy

• The 10% surcharge is a temporary measure currently scheduled to run for 150 days from 24 February 2026
• The U.S. administration has authority to increase this rate (up to 15%) or amend the structure before expiry
• This percentage reflects the additional Section 122 surcharge only and does not replace product-specific duties such as Section 301 or Section 232 tariffs where applicable

If further changes are made to U.S. import tariff policy, the PDDP tariff table will be updated again.
