On June 29, 2026, the U.S. Department of Commerce initiated a new investigation under Section 232 of the Trade Expansion Act of 1962 examining whether imports of anthracite coal and metallurgical bituminous coal threaten U.S. national security. Commerce publicly announced the action on July 2. The investigation sits within the same statutory framework the government has used to justify tariffs on steel, aluminum, and other products, and importers should treat it as a serious signal that new duties or quotas on covered coal could follow.
Products Covered
The investigation is defined by tariff classification. It covers two Harmonized Tariff Schedule of the United States (HTSUS) subheadings: 2701.11.0000 (anthracite coal) and 2701.12.0010 (metallurgical bituminous coal). Any imported product entering under these subheadings falls within the scope of the inquiry, which makes accurate classification a threshold concern for affected importers.
Key Timeline and Deadlines
Section 232 proceedings run on statutory clocks, and the early public-comment window is the most immediate deadline importers need to calendar. The key milestones are:
June 29, 2026 - Section 232 investigation initiated.
July 2, 2026 - Public announcement by Commerce.
July 21, 2026 - Deadline for public comments to Commerce.
Under the governing statute, Commerce generally has up to 270 days from initiation to deliver its report and recommendation to the President, who then has 90 days to decide whether and how to act, including through tariffs, quotas, or other measures. Parties who wish to shape the record should focus first on the July 21 comment deadline. Commerce has asked commenters to address, among other things, the extent to which domestic anthracite production can meet domestic demand, the feasibility of expanding domestic capacity, whether tariffs or quotas are necessary to protect national security, the impact of foreign predatory trade practices on domestic producers, effects on U.S. manufacturing employment if anthracite is not used, and the likelihood of foreign export controls.
Impacted Countries: Canada and Colombia
The countries most directly affected by any resulting import restrictions are Canada and Colombia. According to Commerce, nearly 90% of U.S. coal imports come from these two nations, both of which have free-trade agreements with the United States. Because import volumes are dominated by these two sources, any tariff or quota outcome would fall most heavily on Canadian and Colombian coal exporters and the rail, port, and logistics supply chains that serve them. Notably, the U.S. remains a net exporter of coal overall, shipping roughly 23.7 million short tons in the first quarter of 2026 against only about 737,000 short tons imported, so the practical import exposure is concentrated in these two supplier relationships.
The National Security Rationale in Tension With the Data
A notable feature of this investigation is the tension between the underlying trade data and the policy narrative driving it. The Energy Information Administration reports that anthracite represents only about 1% of domestic coal production, that the U.S. is a net exporter of anthracite, and that both anthracite imports and exports are very small, under 1 million short tons per year. On its face, that data does not suggest imports are undermining domestic production. The Energy Department, however, has argued that the decline of the Appalachian coal industry, where thermal, metallurgical, and anthracite coal share infrastructure and workforce, threatens U.S. steel dominance, and has urged treating metallurgical coal as a critical material. Importers should expect the government's national security theory to rest on this industrial-base argument rather than on import volumes alone. Electric arc furnaces already account for roughly 70% of U.S. steel production and do not rely on metallurgical coal the way traditional blast furnaces do, which further complicates the link between imported coal and steel-sector national security.
What Affected Parties Should Do Now
Confirm classification exposure. Verify whether your imports fall under HTSUS 2701.11.0000 or 2701.12.0010, and assess downstream exposure if you purchase U.S. metallurgical coal for steelmaking.
Consider filing comments by July 21, 2026. The comment record is often the single most important opportunity to influence the scope and outcome of a Section 232 action.
Model potential duty scenarios. Evaluate cost impacts under possible tariff or quota outcomes, particularly for supply from Canada and Colombia.
Review contracts and sourcing options. Consider force majeure, cost-pass-through, and alternative-sourcing provisions in light of possible new duties.
