Effective March 23, 2018, the United States will impose additional duties on steel and aluminum imported from all countries except Canada and Mexico. As we discussed in a recent blogpost, the U.S. issued a 25% tariff on steel and a 10% tariff on aluminum. Anti-dumping duties (ADD) had also been considered, but it would have been difficult for the U.S. to manage so many new ADD cases.


Affected HS numbers

The new tax affects 73 HS numbers for aluminum and 736 HS numbers for steel.

The applicable HTS provisions for steel are:

  • 7206.10 through 7216.50
  • 7216.99 through 7301.10
  • 7302.10
  • 7302.40 through 7302.90
  • 7304.10 through 7306.00
  • 9903.80.01

Aluminum products covered by the proclamation are:

  • Unwrought aluminum (HTS 7601)
  • Aluminum bars, rods, and profiles (HTS 7604)
  • Aluminum wire (HTS 7605)
  • Aluminum plate, sheet, strip, and foil (flat rolled products in HTS 7606 and 7607)
  • Aluminum tubes and pipes and tube and pipe fittings (HTS 7608 and 7609)
  • Aluminum castings and forgings (HTS 7616.99.51.60 and 7616.99.51.70)
  • HTS 9903.85.01



If you would like to request exclusion from these new tariffs, you can read about the formal exclusion process in a recent Federal Register Notice. All exclusion requests are required to be filed at www.regulations.gov. Finally, the U.S. Bureau of Industry and Security has provided instructions and forms regarding the exclusion and objection process for aluminum and steel.



We realize through media channels that the execution of the steel and aluminum tariffs is still very fluid.  As we learn more from U.S. Customs and Border Protection on the topic, we will be sure to share the information with our clients through system alerts.


A note on U.S. imports
