According to the United States-Mexico-Canada Trade Agreement, goods worth between $50 and $117 entering the country through Canadian and American express delivery companies will be subject to a 17% tariff; and for goods worth more than $1 from other countries that have signed international treaties with Mexico, a 19% tariff will also be imposed. As one of the countries that has not signed relevant international treaties with Mexico, China's domestic cross-border e-commerce platforms such as Shein and Temu may be directly affected by this policy.
