President Donald Trump is excluding Canadian and Mexican exports from 10% or 25% duties that began March 4, as long as those goods can qualify for USMCA benefits. The change starts at 12:01 a.m. March 7.

Vehicles that meet the USMCA rules of origin will be able to enter the U.S. duty-free again, for one month, two White House spokespeople said March 5.

China and Canada announced new retaliatory trade restrictions against the U.S. -- and Mexico announced plans to soon release its own set of countermeasures -- after President Donald Trump's administration on March 4 increased tariffs on goods from all three countries. Industry associations said the counter-duties could damage a range of American export industries, including shippers of agricultural products, spirits and other commercial goods.

Commerce Secretary Howard Lutnick, when asked by a Bloomberg TV reporter if tariffs will be hiked on April 2, or if a process begins then, said "some tariffs will come on right away," while others could take three weeks, four weeks, or two months, depending on which law is being used.

From corporate giants to small companies, in farming, manufacturing and retail, Americans said tariffs on Canada and Mexico were damaging their businesses and driving up costs for customers.

A domestic producer recently filed a petition with the Commerce Department and the International Trade Commission requesting new antidumping and countervailing duties on certain chassis and subassemblies imported from Mexico, Thailand and Vietnam. Commerce now will decide whether to begin AD/CVD investigations, which could result in the imposition of permanent AD/CVD orders and the assessment of AD and CVD on importers. The U.S. Chassis Manufacturers Coalition, which consists of the Cheetah Chassis Corporation and Stoughton Trailers, requested the investigation.

Imported goods subject to heading 9903 tariff subheadings, including goods from China, may qualify for informal entry only if the goods are valued at $250 or less, CBP indicated in answers to questions posed by the National Customs Brokers & Forwarders Association of America at a recent meeting.

CBP released notices late March 3 on the implementation of 25% tariffs on most goods from Canada and all goods from Mexico.
