双方关税调整将于5月14日前生效。美国总统唐纳德·特朗普于2月和3月对中国征收的20%芬太尼相关关税将维持不变。不过，双方同意在90天内将对方的“互惠”关税降低115个百分点。
根据联合声明，这实际上意味着美国将暂时将对中国商品的总关税从145%降至30%，而中国将把对美国进口商品的总关税从125%降至10%。

The mutual tariff revisions will be imposed by May 14. US President Donald Trump’s 20% fentanyl-related levies on China, imposed in February and March, will stay. However, each side has agreed to lower “reciprocal” tariffs on the other by 115 percentage points for 90 days.
That effectively means the US will temporarily lower its overall tariffs on Chinese goods from 145% to 30%, while China will cut its levies on American imports from 125% to 10%, according to the joint statement.
