Common criteria:
- WO – wholly obtained (minerals extracted, crops harvested in a party).
- RVC – regional value content above a threshold (often 40%).
- CTC – change in tariff classification (CC, CTH, CTSH).
- PSR – product-specific rules per HS code.
- Accumulation – materials from other parties count as originating.
- Direct consignment and non-alteration in transit.
Steel structures example: non-originating sections (72.16) fabricated into structures (73.08) usually satisfy CTH, but each FTA's PSR must be checked.
