Tariffs on countries that import Venezuelan oil could begin as early as April 2 and will be imposed on countries based on determinations from the State and Commerce departments, said an executive order issued by President Donald Trump on March 24.

President Donald Trump acknowledged that the Ontario premier rolled back a surcharge on electricity exports to the U.S. and told reporters at the White House that he "probably" wouldn't increase to 50% the tariffs on Canadian steel and aluminum set to take effect on March 12, as he had threatened about five hours earlier.

The U.S. will double tariffs slated to take effect March 12 on Canadian aluminum and steel, from 25% to 50%, in response to Ontario's decision to place 25% export surcharges on electricity purchased in the U.S., President Donald Trump said today on Truth Social.

All Section 232 quota and tariff-rate quota entries must be presented to CBP by 4:30 p.m. today, local port time, to avoid tariffs that snap back into effect March 12 for certain countries, said CBP in a CSMS message. While Section 232 country exemptions and TRQs for Argentina, Australia, Brazil, Canada, EU countries, Japan, Mexico, South Korea and the U.K. expire at midnight, CBP regulations require that quota entries be filed only during CBP’s official office hours.

Section 232 tariffs on the new steel and aluminum “derivatives” outside of Chapters 73 and 76 will take effect at 12:01 a.m. tonight, CBP said in a pair of CSMS messages. The March 12 effective date is in line with the other Section 232 duty increases announced in February, including an end to all country-specific quotas and exclusions and an increase in aluminum tariffs to 25%.

Section 232 tariffs on a new list of steel and aluminum “derivatives” outside of Chapters 73 and 76 are now set to take effect, after the Commerce Department released a notice that “adequate systems are in place to fully, efficiently, and expediently process and collect tariff revenue for covered articles for both steel and aluminum.”

An exemption for USMCA-qualifying goods from 25% tariffs on goods from Mexico will also take effect March 7, alongside the USMCA exemption for Canada, according to an executive order signed today by President Donald Trump. Like the Canada order, it also lowers the tariff for potash that doesn’t qualify for the USMCA exemption to 10%.

President Trump posted on social media: "After speaking with President Claudia Sheinbaum of Mexico, I have agreed that Mexico will not be required to pay Tariffs on anything that falls under the USMCA Agreement. This Agreement is until April 2nd. I did this as an accommodation, and out of respect for, President Sheinbaum. Our relationship has been a very good one, and we are working hard, together, on the Border, both in terms of stopping Illegal Aliens from entering the United States and, likewise, stopping Fentanyl. Thank you to President Sheinbaum for your hard work and cooperation!"

An exemption for USMCA-qualifying goods from 10% and 25% tariffs on goods from Canada will take effect at 12:01 a.m. on March 7. An executive order signed by President Donald Trump exempts all goods “that are entered free of duty as a good of Canada under the terms of general note 11” of the tariff schedule from the tariffs, “including any treatment set forth in subchapter XXIII of chapter 98 and subchapter XXII of chapter 99.”

The President has amended the executive orders imposing 25% tariffs on all Mexican goods, 10% tariffs on Canadian energy and 25% tariffs on other Canadian imports so that any good that qualifies for USMCA preference will be able to avoid the tariff, the White House said.
