Miscellaneous Tariff Bill (MTB) Information

Under current law, MTBs do not relieve importers of additional duties imposed under Chapter 99 of the Harmonized Tariff Schedule, including products of China subject to section 301 duties and steel and aluminum products subject to section 232 duties.

This area contains resources and information for the Miscellaneous Tariff Bill (MTB) petition process being administered by the Commission in accordance with the American Manufacturing Competitiveness Act of 2016 (AMCA). The AMCA established a new process for the submission and consideration of requests for temporary duty suspensions and reductions.

On June 9, 2020, the Commission delivered its preliminary report on miscellaneous tariff bill petitions it received under the 2016 American Manufacturing Competitiveness Act (AMCA).  The Commission will re-open the MTBPS comment portal from June 12 – June 22, 2020 to allow the public to provide additional information on petitions in Category VI in the preliminary report.  Please read this notice, published in the Federal Register on April 24, 2020, for more information.
