What's happened
On August 1, 2025, the US imposed 50% tariffs on semi-finished copper products and copper-intensive goods, excluding refined copper and raw materials. This unexpected scope caused a historic plunge in US copper futures and a surge in inventories, disrupting global markets. Concurrently, the US will scrap the $800 de minimis import exemption from August 29, impacting low-value UK exports to the US.
What's behind the headline?
Market Disruption and Policy Nuance
The Trump administration's copper tariffs have upended a lucrative arbitrage trade by imposing a 50% duty on semi-finished copper products and copper-intensive goods, while exempting refined copper and raw materials like cathodes. This selective approach has caused a record 20% intraday plunge in US copper futures and a surge in US warehouse inventories, reflecting a sudden glut from pre-tariff stockpiling.
Strategic Intent vs. Market Reality
The tariffs aim to bolster US domestic copper production and reduce dependence on foreign suppliers, notably China, which dominates global copper smelting and refining. However, by excluding refined copper and raw materials, the policy offers limited support to US mining and smelting industries, which lack capacity to meet demand. This benefits major copper exporters like Chile and Peru, while US producers face ongoing challenges.
Broader Trade Implications
The accelerated removal of the $800 de minimis exemption on August 29 will impose tariffs on low-value imports from the UK and other countries, increasing costs for exporters and potentially reducing competitiveness in the US market. This move aligns with broader efforts to protect American manufacturing but risks disrupting supply chains and consumer prices.
Forecast and Impact
The copper market will likely experience continued volatility as inventories adjust and trade flows recalibrate. The US government's planned review in mid-2026 and potential phased tariffs on refined copper suggest ongoing trade tensions. For consumers and businesses, higher costs on copper products and low-value imports will translate into price increases and supply uncertainties in the near term.
What the papers say
Bloomberg's Joe Deaux reported on July 30 that the tariffs would take effect August 1 but with limited scope, surprising markets. The South China Morning Post detailed the tariff exclusions, noting the exemption of refined copper and raw materials, and highlighted China's dominant role in global copper refining. Business Insider UK described the historic 20% plunge in US copper futures and the resulting inventory surge, emphasizing the market's reaction to the tariff's limited coverage. The Guardian underscored the tariffs' impact on US producers and the boost to Chile and Peru, while quoting analysts who called the move a partial backtrack by the Trump administration. The Scotsman and The Independent focused on the accelerated removal of the $800 de minimis exemption, warning of significant impacts on UK exporters of low-value goods to the US, with Parcelhero's David Jinks highlighting potential cost increases for consumers and risks of unsold inventory. These sources collectively illustrate a complex trade policy with significant market and economic repercussions.
How we got here
President Trump announced tariffs on copper imports in July 2025 to boost US domestic production and reduce reliance on foreign sources, especially China. The tariffs target semi-finished copper products but exempt refined copper and raw materials. Separately, the US accelerated the removal of the de minimis import exemption, which previously allowed low-value goods under $800 to enter duty-free.
