拜登对352种商品关税豁免,是特朗普时期对549种关税豁免产品的部分延续而已
2018年开始,特朗普共对中国产品加征了四轮关税,这四轮关税在此期间曾经历不同批次的关税豁免和原豁免清单的继续延长。一开始特朗普政府对2200种产品进行了豁免,后来美国针对前四轮加征清单的多批豁免已经陆续到期,但其中的549种产品豁免被延长到了2020年年底,然后也过期了
拜登2022年3月宣布,恢复了549种产品中352种的关税豁免,"美国贸易代表办公室今年3月发声明称,重新豁免对352项从中国进口商品的关税,适用于在2021年10月12日至2022年12月31日之间进口自中国的商品"然后这些产品的豁免在不断续约,最后特朗普上台前拜登签署总统令,把352种关税豁免延续到了到2025年8月
所以这些关税豁免已经包括在了51.5%当中

The U.S. Trade Representative's office said on Wednesday it has reinstated 352 expired product exclusions from U.S. "Section 301" tariffs on Chinese imports, well short of the 549 exclusions that it was previously considering.
The Trump administration initially granted more than 2,200 exclusions to the tariffs to provide relief to certain industries and retailers. Most were allowed to expire, but 549 were extended for a year, and these expired at the end of 2020.
