Tariff Updates

Canada

As of October 7, 2025, the United States, under the second Trump administration, has imposed significant new tariffs on Canada's Diversified Metals & Mining industry. Initially, a 25% tariff was placed on all Canadian imports and a 10% tariff on energy resources and critical minerals, effective March 4, 2025. While goods compliant with the United States-Mexico-Canada Agreement (USMCA) were later exempted, this exemption specifically excluded steel and aluminum. Tariffs on steel and aluminum were introduced at 25% and later escalated to 50% on June 4, 2025, creating major trade friction.

Existing Trade Agreements

Canada and the United States share a substantial trade relationship in the metals and mining sector, governed by the USMCA. In 2022, over half of Canada's mineral exports, valued at more than C$80 billion, were sent to the U.S. In 2023, this figure was $38 billion. Canada is the largest U.S. supplier of both steel and aluminum, with annual exports valued at approximately $17 billion for iron and steel and $13 billion for aluminum, highlighting the deep integration of the two economies in this industry.

New Tariff Changes

The 2025 tariff policy represents a significant departure from the largely tariff-free trade established under the USMCA. Citing national security and the protection of domestic industries, the Trump administration shifted from targeted tariffs to broad-based, escalating levies. This change has particularly affected the steel and aluminum sectors, which were previously exempt. The policy has disrupted the highly integrated North American supply chains and created significant economic uncertainty, becoming a key issue in discussions between Canadian Prime Minister Mark Carney and U.S. President Donald Trump.

Mexico

As of October 7, 2025, the U.S. implemented significant new tariffs on Mexican goods, including those in the diversified metals and mining industry. On March 4, 2025, a broad 25% tariff was applied under the International Emergency Economic Powers Act (IEEPA). This was followed by a 25% tariff on all steel and aluminum imports on March 12, 2025, based on Section 232 of the Trade Expansion Act of 1962. These tariffs were subsequently increased to 50% on June 4, 2025. The scope was further expanded on August 19, 2025, to include 407 additional items, and a separate 50% tariff on copper imports became effective on August 1, 2025.

Existing Trade Agreements

Prior to the new tariffs, trade was governed by the United States-Mexico-Canada Agreement (USMCA), which promoted largely free trade. In 2024, bilateral trade in goods totaled approximately $839.9 billion. U.S. imports from Mexico were about $505.9 billion, while exports reached $334 billion. In the metals sector for 2024, U.S. exports to Mexico included $7.06 billion in iron and steel and $4.16 billion in aluminum. U.S. imports of 'Miscellaneous metal products' from Mexico amounted to $2.85 billion.

New Tariff Changes

The 2025 tariffs represent a major policy shift away from the free-trade principles of the USMCA, which had established 0% tariffs for most products. Unlike the 2018 tariffs, the new measures use justifications like the IEEPA and Section 232 national security provisions to impose broad duties outside the USMCA framework. This move towards protectionism has created new trade barriers and prompted retaliatory tariffs from Mexico on U.S. goods, including steel. This escalation disrupts the highly integrated North American supply chains that have been built over decades.

Impact on Industry Sub-Areas

Base & Precious Metals Mining: A 25% tariff was implemented for non-USMCA compliant gold and silver, while copper faces a potential 50% tariff under Section 232.
Critical & Strategic Minerals Mining: Non-USMCA compliant critical minerals, such as lithium and nickel, now face tariffs ranging from 10% to 25%.
Primary Aluminum Production: The tariff on primary aluminum from Mexico increased from 0% under USMCA to 50% as of June 4, 2025.
Integrated Iron & Steel Production: Tariffs on steel products rose from 0% to 50%, with the scope expanded on August 19, 2025, to include 407 additional items.
Metal Service Centers & Distribution: These businesses face a 50% cost increase on steel and aluminum inputs and a 25% tariff on other non-USMCA compliant processed metals.
Scrap Metal Recycling & Secondary Production: A potential 25% tariff on non-USMCA compliant scrap metal could impact trade, including the 95,781 tons of aluminum scrap exported from the U.S. to Mexico in 2024.

Trade Impacted by New Tariff

The metals and mining industry has been specifically targeted by the new tariffs. Goods that fail to meet USMCA's rules of origin are subject to the 25% tariff. Crucially, all steel and aluminum products, regardless of USMCA compliance, are now subject to the 50% Section 232 tariff. Given that the U.S. imports an estimated $18 billion in iron, steel, copper, and aluminum from Latin America, a significant volume of this trade with Mexico is now directly impacted by these substantial duties.

Trade Exempted by New Tariff

A substantial portion of bilateral trade remains exempt from the new tariffs. According to reports from August 2025, over 84% of Mexico-U.S. trade continues to be tariff-free. This is because the majority of goods traded meet the rules of origin required to be considered USMCA-compliant. These exemptions primarily cover industries and products not specifically targeted by the national security and emergency powers actions.

China

As of October 7, 2025, the United States has imposed new tariffs on China's diversified metals and mining industry, escalating the ongoing trade dispute. Key measures, effective on various dates in 2025, include doubling the tariffs on steel and aluminum to 50% as of June 4, 2025. Additionally, a new 50% tariff on copper imports was enacted on August 1, 2025. These tariffs build upon a broader 25% tariff on a range of critical minerals that became effective in 2024, aiming to reduce reliance on Chinese imports for materials vital to national security.

Existing Trade Agreements

In 2024, the total trade in goods between the U.S. and China was approximately $658.9 billion. While comprehensive data for the entire diversified metals and mining sector isn't consolidated, key sub-sectors represent significant trade volumes. U.S. imports of iron and steel from China totaled about $537.11 million in 2024. During the same period, imports of aluminum were substantially higher, amounting to $3.07 billion. These figures highlight the significant trade flow that will be affected by the newly imposed tariffs.

New Tariff Changes

The new tariff policy represents a significant escalation from the previous framework established under the Trump administration's Section 232 and Section 301 actions. Previously, steel and aluminum faced tariffs of 25% and 10% respectively. The 2025 policy doubles these rates to 50% and expands the scope to include a new 50% tariff on copper. This shift is driven by a stated goal to bolster domestic production and enhance economic resilience, especially considering the U.S. was 100% reliant on imports for 12 critical minerals and over 50% reliant for another 28 in 2024.

Impact on Industry Sub-Areas

Base & Precious Metals Mining: A new 50% tariff on copper imports became effective on August 1, 2025.
Critical & Strategic Minerals Mining: As of 2024, a new 25% tariff applies to a range of 'other critical minerals', with a 25% tariff on natural graphite and permanent magnets scheduled for 2026.
Primary Aluminum Production: The Section 232 tariff on most aluminum imports was doubled from 10% to 50%, effective June 4, 2025.
Integrated Iron & Steel Production: The Section 232 tariff on the majority of steel imports was increased from 25% to 50%, effective June 4, 2025.
Metal Service Centers & Distribution: The tariff increases on steel and aluminum to 50% will significantly elevate material costs for metal service centers, impacting their supply chain and pricing.
Scrap Metal Recycling & Secondary Production: No new, specific tariffs have been announced for scrap metal imports from China as of October 7, 2025, but the sector remains vulnerable to retaliatory actions by China.

Trade Impacted by New Tariff

The new tariffs directly impact billions of dollars in trade. The increase to a 50% tariff rate affects approximately $537.11 million in iron and steel imports and $3.07 billion in aluminum imports, based on 2024 trade figures. Furthermore, a new 50% tariff is now applied to copper imports. A broader range of strategic materials are also affected, with a 25% tariff impacting an assortment of critical minerals, and a future 25% tariff set for 2026 on natural graphite and permanent magnets.

Trade Exempted by New Tariff

The U.S. Trade Representative (USTR) has maintained a process for tariff exclusions, extending certain Section 301 tariff exclusions for a variety of Chinese products that were set to expire. These extensions provide temporary relief from the additional duties for specific items. However, the exact monetary value of trade within the diversified metals and mining sector that benefits from these exemptions is not readily quantifiable, as it requires a detailed analysis of import data at the specific Harmonized Tariff Schedule (HTS) code level.

South Korea

As of October 7, 2025, the United States has implemented significant new tariffs on South Korea's metals and mining industry. A key measure, effective June 4, 2025, was the increase of Section 232 tariffs on steel and aluminum to 50%. These tariffs were expanded on August 18, 2025, to include 407 new categories of derivative products. Additionally, a separate Section 232 investigation led to a 50% tariff on certain copper products, which took effect on August 1, 2025, further impacting South Korea's non-ferrous metals sector.

Existing Trade Agreements

Bilateral trade in goods between the U.S. and South Korea reached $200 billion in 2024. Within this trade, U.S. steel imports from South Korea were valued at $2.9 billion, making it the fourth-largest supplier. Similarly, U.S. aluminum imports from South Korea amounted to $781 million in the same year, also ranking fourth. More recent 2022 data shows U.S. imports of Base Metals, Iron, Steel, and Tools from South Korea at $9.3 billion. These trade flows were previously governed by the U.S.-South Korea Free Trade Agreement (KORUS), which has been largely superseded by the new tariff measures.

New Tariff Changes

The new tariff policy represents a dramatic shift from the previous approach. Previously, under the 2018 Section 232 rules, South Korea had a quota for steel exports to the U.S. instead of a tariff. However, as of March 2025, all country-specific exemptions and most product exclusions were terminated. This moved South Korea from a quota system to a high-tariff system, with rates on steel and aluminum increasing from 25% and 10% respectively to a uniform 50%. This new protectionist stance effectively overrides the tariff elimination provisions of the KORUS agreement for these specific goods.

Impact on Industry Sub-Areas

Base & Precious Metals Mining: A new 50% tariff on certain copper imports was implemented on August 1, 2025, following a Section 232 investigation.
Critical & Strategic Minerals Mining: While no specific new tariffs are in place as of October 7, 2025, the Commerce Department has initiated Section 232 investigations, signaling potential future tariffs.
Primary Aluminum Production: The tariff on aluminum imports from South Korea was increased from 10% to 50%, effective June 4, 2025, with all exemptions eliminated.
Integrated Iron & Steel Production: South Korea's duty-free quota was replaced with a 25% tariff in March 2025, which was then increased to 50% on June 4, 2025.
Metal Service Centers & Distribution: On August 18, 2025, the 50% tariffs were expanded to 407 new subheadings for derivative steel and aluminum products, directly impacting distributors.
Scrap Metal Recycling & Secondary Production: There are no new U.S. tariffs specifically targeting scrap metal imports from South Korea as part of these recent actions.

Trade Impacted by New Tariff

The new 50% tariffs impact the vast majority of South Korea's metals trade with the U.S. This affects nearly all of the $2.9 billion in steel and $781 million in aluminum (based on 2024 figures) previously exported to the U.S. The impact was broadened on August 18, 2025, when the tariffs were extended to 407 new HTSUS subheadings for derivative steel and aluminum products. Additionally, the new 50% tariff on certain copper imports directly impacts South Korea's non-ferrous metals industry.

Trade Exempted by New Tariff

Under the new policy enacted in 2025, virtually no trade in the targeted metal categories is exempt. As of March 12, 2025, all previously approved general exclusions from the Section 232 tariffs were terminated. Furthermore, the Department of Commerce has also ended the process for companies to request new product-specific exclusions. The primary area not targeted by these new U.S. tariffs appears to be scrap metal imports from South Korea.

Germany

As of October 7, 2025, the Trump administration has instituted significant new tariffs on Germany's metals and mining industry. Citing national security under Section 232 of the Trade Expansion Act of 1962, a proclamation signed on June 3, 2025, raised import tariffs on both steel and aluminum to 50%, effective the following day. This measure represents a substantial increase and a departure from a prior system of negotiated quotas. Additionally, the U.S. announced a 50% tariff on imports of semi-finished copper products and certain derivatives, which took effect on August 1, 2025, further expanding the scope of the protectionist trade policy.

Existing Trade Agreements

Germany maintains a robust trade relationship with the United States in the diversified metals and mining sector. In 2024, Germany's direct exports of iron and steel to the U.S. were valued at $1.32 billion. Globally, Germany is a major player, with total 'Metals' exports reaching $122 billion in 2023, making it the world's second-largest exporter in this category. Beyond direct exports, Germany's indirect steel exports to the U.S., embedded within steel-intensive goods like machinery, amount to approximately 2.4 million tons annually. The total value of all goods traded between Germany and the U.S. in 2024 was €253.3 billion.

New Tariff Changes

The 2025 tariff policy marks a significant escalation from previous measures. Initially, the Trump administration had set steel and aluminum tariffs at 25% and 10% respectively, with various exemptions for the EU. However, proclamations in early 2025 eliminated all country-based exemptions and subsequently doubled the tariffs on steel and aluminum to 50%. A major procedural change was the termination of the process for companies to request product-specific exclusions, signaling a much stricter, non-negotiable stance. The policy also newly targeted copper products and suspended the de minimis rule for shipments under $800, tightening import conditions across the board.

Impact on Industry Sub-Areas

Base & Precious Metals Mining: A new 50% tariff on semi-finished copper products was implemented on August 1, 2025, although raw materials like copper ores and concentrates are exempt.
Critical & Strategic Minerals Mining: This sector is largely exempt from the new tariffs, with 'unavailable natural resources' subject only to standard MFN rates per an August 2025 U.S.-EU agreement.
Primary Aluminum Production: The tariff on primary aluminum from Germany increased from an effective 0% under a quota system to 25% on March 12, 2025, and was then doubled to 50% on June 4, 2025.
Integrated Iron & Steel Production: The tariff on German steel products rose from an effective 0% under the prior tariff-rate quota to 50% as of June 4, 2025.
Metal Service Centers & Distribution: This sector is directly impacted by the 50% tariffs on steel and aluminum effective June 4, 2025, leading to drastically higher import costs.
Scrap Metal Recycling & Secondary Production: This sub-area is affected by EU retaliatory tariffs on U.S.-origin ferrous and aluminum waste and scrap (headings 7204 and 7602).

Trade Impacted by New Tariff

The new tariffs directly impact a substantial portion of Germany's metal exports to the U.S. The 50% tariffs affect all primary steel and aluminum products, which form the bulk of direct metal trade. The impact was broadened in August 2025 when the U.S. expanded the list of dutiable goods to include 407 additional product codes for steel and aluminum derivative products, affecting a wide range of manufactured items from construction materials to household appliances. Furthermore, the new 50% tariff on semi-finished copper products and certain copper derivatives directly affects downstream value-added processing industries.

Trade Exempted by New Tariff

Despite the broad application of new tariffs, certain categories remain exempt. A joint U.S.-EU statement in August 2025 clarified that 'unavailable natural resources' will only be subject to standard Most Favored Nation (MFN) tariffs, a category that likely includes critical and strategic minerals such as rare earths and lithium. Furthermore, the 50% tariff on copper products does not apply to raw input materials like copper ores and concentrates. An exemption process also exists for derivative articles made from steel that was 'melted and poured' or aluminum that was 'smelted and cast' within the United States, aiming to protect domestic primary metal producers.
