今天，唐纳德·特朗普总统签署了一项行政命令，取消了对从中国进口的低价值商品的免税最低限度待遇，这是应对合成阿片类药物非法流入美国造成的持续健康紧急情况的关键一步。

Following the Secretary of Commerce’s notification that adequate systems are in place to collect tariff revenue, President Trump is ending duty-free de minimis treatment for covered goods from the People’s Republic of China（PRC）and Hong Kong starting May 2, 2025 at 12:01 a.m. EDT.

在商务部长通知已建立适当的关税征收系统后，特朗普总统将从美国东部时间 2025 年 5 月 2 日凌晨 12：01 开始，终止对来自中华人民共和国 （PRC） 和香港的受管制商品的免税最低限度待遇。
Imported goods sent through means other than the international postal network that are valued at or under $800 and that would otherwise qualify for the de minimis exemption will be subject to all applicable duties, which shall be paid in accordance with applicable entry and payment procedures.
通过国际邮政网络以外的方式发送的进口货物，如果价值等于或低于 800 美元，并且符合最低限度豁免条件，则需缴纳所有适用的关税，这些关税应根据适用的入境和付款程序支付。
All relevant postal items containing goods that are sent through the international postal network that are valued at or under $800 and that would otherwise qualify for the de minimis exemption are subject to a duty rate of either 30% of their value or $25 per item（increasing to $50 per item after June 1, 2025）. This is in lieu of any other duties, including those imposed by prior Orders.

Carriers transporting these postal items must report shipment details to U.S. Customs and Border Protection（CBP）, maintain an international carrier bond to ensure duty payment, and remit duties to CBP on a set schedule.
运输这些邮件的承运人必须向美国海关和边境保护局 （CBP） 报告货件详情，保持国际承运人担保以确保缴纳关税，并按设定的时间表向 CBP 缴纳关税。
CBP may require formal entry for any postal package instead of the specified duties.
CBP 可能要求任何邮政包裹正式入境，而不是指定关税。
The Secretary of Commerce will submit a report within 90 days assessing the Order’s impact and considering whether to extend these rules to packages from Macau.
商务部长将在 90 天内提交一份报告，评估该命令的影响，并考虑是否将这些规则扩展到来自澳门的包裹。
