Section 338 Tariffs Now In Effect

The three-day pause has expired. Effective 9:01 p.m. PST Friday, Aug. 21 (12:01 a.m. ET Saturday, Aug. 22), the 50% Section 338 tariffs on certain Canadian-origin goods are in effect.

The additional ad valorem duties imposed in Proclamations 11046, 11047, and 11048 took effect at 12:01 a.m. ET on Saturday, Aug. 22. Canadian-origin goods classified under the covered provisions are now subject to the additional 50% duty at the time of entry.

What this means for your shipments:

• CUSMA/USMCA does not exempt these duties.
• Duties stack. The new 50% is charged on top of the regular duty owed.
• Confirm crossing times with your carrier.
• Advance duty payment may be required for entries on or after August 21. Late payment risks interest, cargo holds, mandatory cash payment, and other CBP action.
• Shipments may face delays.

Please work with your trucking partners and carriers if you wish to reschedule any importations to the US at this time.
