Duty Suspension and ITC Petitions: How to Reduce or Eliminate Import Duties Legally

The Miscellaneous Tariff Bill (MTB) process provides a legal mechanism for US importers and domestic manufacturers to petition for temporary duty suspensions or reductions on specific imported products that are not available from domestic sources. Administered by the International Trade Commission (ITC) under the American Manufacturing Competitiveness Act of 2016, the MTB process allows petitioners to request that duties on specific HTS subheadings be temporarily suspended or reduced, typically for a period of three years. Successful petitions can eliminate or significantly reduce duty costs on critical inputs, components, and materials, providing a competitive advantage to US manufacturers who rely on imported goods in their production processes.

How the MTB Process Works

The MTB process follows a defined cycle that typically occurs every three years. The ITC opens a petition window during which any member of the public can submit petitions for duty suspensions or reductions on specific products. Each petition identifies the product by its HTS classification, provides a detailed description of the merchandise, estimates the annual import value, and explains why the product is not available from domestic sources. The ITC reviews each petition, publishes them for public comment, and then compiles a report for Congress with its recommendations. Congress then considers the ITC's report and enacts an MTB that includes the approved duty suspensions and reductions. The entire process, from petition filing to enactment, typically takes 18 to 24 months.

Eligibility Requirements

• The product must be identifiable by a specific HTS subheading or a narrower product description within an existing subheading
• The product must not be available from domestic production in commercially meaningful quantities
• The estimated annual duty loss to the Treasury must not exceed $500,000 per petition
• The petition must not be for a product that is the subject of an active trade remedy (AD/CVD) order
• The petition must demonstrate that the duty suspension would benefit US economic interests, such as supporting domestic manufacturing or reducing costs for US companies
• The product description must be sufficiently specific to be administrable by CBP at the border

Filing a Petition

Petitions are filed electronically through the ITC's MTB petition portal during designated filing windows. The petition form requires detailed information about the product, including its commercial name, HTS classification, physical and chemical characteristics, principal uses, and the countries from which it is primarily imported. The petitioner must also provide an estimate of annual import volumes and values, the current duty rate, and the requested duty rate (typically zero). Supporting documentation should include evidence that the product is not available domestically, such as market research, supplier surveys, or trade association data. The quality and completeness of the petition directly affect its likelihood of approval, so investing time in preparation is essential.

Strategic Benefits of Duty Suspensions

The financial impact of a successful duty suspension can be significant, particularly for importers of high-value raw materials, specialty chemicals, or industrial components with duty rates in the range of 3% to 8%. While individual duty savings may seem modest on a per-unit basis, the cumulative effect across annual import volumes can amount to hundreds of thousands of dollars in savings. Beyond the direct duty savings, a duty suspension can improve product competitiveness by reducing landed costs, support domestic manufacturing by reducing the cost of imported inputs, and create pricing advantages over competitors who have not obtained similar suspensions.

Current MTB Cycle and Timing

The most recent MTB was enacted in December 2024, providing temporary duty suspensions and reductions on approximately 1,700 products through December 2027. The next petition filing window is expected to open in 2027 for the subsequent MTB cycle. Importers interested in petitioning for duty suspensions should begin preparing their petitions well in advance of the filing window, which typically lasts only 60 days. This preparation includes confirming the HTS classification of the product, gathering evidence of domestic non-availability, calculating the estimated annual duty savings, and coordinating with trade associations or other importers who may benefit from the same suspension.

Working with Trade Associations

Many successful MTB petitions are filed by trade associations on behalf of their members, which can reduce the cost and effort for individual companies while strengthening the petition through industry-wide support. Trade associations can aggregate data on domestic non-availability, provide broader economic impact analysis, and mobilize member companies to support the petition during the public comment period. If your industry has an active trade association engaged in MTB advocacy, coordinating with them is often the most efficient path to a successful petition. Even if you file individually, consulting with other importers of the same product can help identify potential objections and strengthen your petition.

The MTB process represents a legitimate and well-established path to reducing import duty costs. While it requires planning, preparation, and patience, the potential savings make it well worth pursuing for importers of products not available from domestic sources. By understanding the process, preparing thorough petitions, and engaging proactively with the ITC review process, importers can secure duty suspensions that provide meaningful competitive advantages and cost savings for years to come.
