贸易投资一体化发展思路下，海外投资未动，原产地筹划与布局必须先行。在全球产业链碎片化的同时，原产地规则也同样复杂碎片化。美国优惠性原产地规则以《美国协调关税税则》总注释为主要渊源，形成两大FTA模式，涵盖税则归类改变、区域价值含量等核心标准，对汽车、纺织品等敏感行业规制严苛，《美墨加协定》更设四重叠加要求、隐形劳工条款、向下追溯等特殊规则。现有研究对该规则的系统性剖析不足，我国企业因中美无自贸协定忽视其价值，易陷入第三方转运或微小加工、难以证明产业链迁移经济合理性等合规误区。我国商界需摒弃短期思维，出海前先进行原产地规则全链协同筹划与管理，通过网状倒序筹划、吃透主规则、善用补充规则与程序工具等路径，合规跨越壁垒，稳定拓展北美市场，筑牢可持续海外发展根基。

Under the perspective of integrating trade and investment, planning and layout of rules of origin must precede overseas investment. As the global industrial chain becomes fragmented, rules of origin have also grown increasingly complex and fragmented. The General Notes of the HTSUS contains the most part of US’preferential rules of origin which forms two major RoO models. These rules cover core standards such as tariff classification changes and RVC, imposing stringent regulations on sensitive industries like automobiles and textiles. The USMCA further introduces special provisions including quadruple superimposed requirements, hidden labor clauses, and“roll-down”rules. Existing research lacks in-depth systematic analysis of these rules. Due to the absence of a free trade agreement between China and the US, Chinese enterprises often overlook their value and are prone to falling into compliance pitfalls such as third-party transshipment, minor processing, or difficulty to prove the economic rationality of industrial chain relocation. Chinese businesses need to abandon short-term thinking and conduct full-chain collaborative planning and management of rules of origin before and after going global. By adopting approaches such as reverse planning, thoroughly grasping core rules, and making good use of residual rules and procedural tools, enterprises can cross barriers in compliance, steadily expand the North American market, and lay a solid foundation for sustainable overseas development.
