Preferential origin rules determine tariff concessions via value content thresholds, PSR, or change in heading tests.

Preferential origin criteria determine tariff treatment under each listed trade agreement using principal methodologies: value of non originating material thresholds, product specific rules (PSR), and change in tariff heading (CTH/CTSH). The table maps each agreement to its implementing customs notifications, specifies whether origin is governed by exclusive PSR, percentage value tests, or hybrid value+CTH rules, and identifies applicable partner countries and special relaxations for least developed countries.
