中际旭创 20250406 摘要 Q&A 关税政策对中际旭创的影响及公司应对策略是什么？ 公司目前正在根据相关的关税政策进行研究，特别是评估产品中镁含量是否超 过 20%。如果符合要求，公司将提交关税豁免申请。公司也在密切关注海外客 户的反应，目前客户没有调整需求或改变现有贸易条款。此外，公司已具备在 泰国厂全面生产和出货光伏产品的能力。 这种情况是不成立的。即使将产品从泰国运到新加坡，再由新加坡出口到美国， 原产地仍然是泰国。关税是根据原产地征收的，而不是根据中转地。因此，通 过新加坡进行转口贸易并不能规避关税。 • 中际旭创已具备泰国工厂全面生产和出货光伏产品的能力，有效规避美国 加征关税对上游高端光芯片采购的影响，所有芯片可直接发往泰国工厂生 产。 • 尽管芯片供应整体仍然紧张，但随着硅光产品产量逐步提升，预计 2025 年 二季度起供应情况将有所缓解，下半年 EML 芯片的紧张状况有望进一步改 善。 • 中际旭创的 1.6T 产品预计在 2025 年二季度出货量将高于一季度，但大规 模放量预计在下半年。整体需求相较去年下半年有所减少，主要原因是客 户需求有所延迟。 • 针对进口芯片用于海外客户，中际旭 ...
