Copper shipments into the United States continued to surge as traders sought to capitalize on the price premium between the COMEX and London Metal Exchange (LME) markets ahead of a potential U.S. decision on refined copper import tariffs. According to IHS Markit shipping data, more than 200,000 tonnes of refined copper arrived at U.S. ports during July, marking the highest monthly inflow in more than a decade. Combined inventories held on COMEX and LME facilities in the United States have now exceeded 740,000 tonnes, while additional material remains in storage at U.S. ports awaiting delivery. The movement of metal into the U.S. has tightened availability in other key trading hubs. Market participants reported significant inventory declines at bonded warehouses in Shanghai, where stocks have fallen sharply since the beginning of the year as cargoes have been redirected to the U.S. to capture favorable arbitrage opportunities. The premium of COMEX copper over LME prices has remained well above historical norms, providing sufficient margin to offset transportation, insurance and warehousing costs. The shift comes as the U.S. administration continues to evaluate potential tariffs on refined copper imports. While the timing and scope of any measures remain uncertain, the prospect of future trade restrictions has already reshaped global trade flows and inventory distribution. The continued migration of copper inventories into the United States is tightening physical availability across international markets and supporting a firmer supply outlook outside North America. Any delay, revision or cancellation of proposed U.S. import tariffs could narrow the COMEX-LME price premium, potentially reversing some of the recent inventory movements and increasing short-term price volatility.

Copper prices climbed to around US$14,000 per tonne on the London Metal Exchange (LME), reaching their highest level in two months as traders continued to monitor record inflows of copper into the United States ahead of an anticipated decision on refined copper import tariffs. According to foreign media reports, more than 200,000 tonnes of copper arrived at U.S. ports during July, representing the largest monthly inflow recorded by IHS Markit since it began tracking the data in 2014. The surge has significantly increased inventories at U.S. warehouses and ports while reducing the volume of metal available to consumers in other regions. The inflows have continued despite uncertainty over potential U.S. tariffs on refined copper imports. Although the U.S. Commerce Department was expected to submit its recommendations by the end of June, no formal decision has yet been announced. The sustained premium of U.S. copper prices over LME prices has continued to support profitable arbitrage opportunities, encouraging traders to redirect material into the U.S. market. Market Impact: The concentration of copper inventories in the United States is tightening physical availability elsewhere, reinforcing an already constrained global market. With copper prices remaining near historic highs and demand supported by electrification, power infrastructure and advanced manufacturing, any tariff decision that further alters global trade flows could intensify regional supply imbalances and provide additional upside for international copper prices.

[SMM Express] South Africa's total chrome ore exports reached 2,403.95kt in June 2026, slipping 0.90% month-on-month but still up sharply by 38.86% year-on-year. The marginal monthly pullback suggests export volumes are levelling off after a period of strong growth, even as the scale of the annual gain confirms that underlying external demand for South African chrome ore remains robust. China remained the dominant destination, absorbing 67.61% of June's total export volume, underscoring how concentrated South Africa's chrome ore trade continues to be around Chinese ferrochrome demand. Singapore and the UAE followed as the second- and third-largest destinations, at 7.85% and 7.82% respectively, together accounting for a modest but notable share outside the core China-linked trade flow.

High ore costs, tight spot availability and weak stainless demand pin China's benchmark NPI index inside a RMB 7/nickel-point range in July, before an Indonesian policy jolt lifts it to a monthly high of RMB 1,129.5.

The SEA secondary aluminum market remained mixed this week. Aluminum scrap prices were largely stable, while ADC12 remained under pressure due to weak downstream demand. Buying activity stayed cautious, although UBC scrap held firm on tighter supply and steady recycling demand. Market attention also shifted to the EU's Carbon Border Adjustment Mechanism (CBAM), with growing focus on carbon reporting, recycled content, and supply chain traceability as compliance requirements continue to evolve.

The ongoing delay by the White House on potential refined copper import tariffs under President Donald Trump is accelerating structural dislocations across the global physical copper market. Although the statutory timeline for U.S. Commerce Secretary Howard Lutnick to deliver a recommendation has lapsed without a public ruling, the regulatory ambiguity itself has become a primary driver of global trade dynamics. By keeping the tariff threat active, the U.S. has sustained an elevated delivery premium that continues to incentivize aggressive physical inflows into American ports. Over the past 18 months, this mechanism has allowed the country to build a substantial domestic stockpile of a critical metal essential to both green energy transition and advanced technology sectors. However, this deliberate accumulation has come at the direct expense of liquidity in non-U.S. markets. Physical metal is being systematically diverted away from international hubs, driving rapid inventory drawdowns across both London Metal Exchange and Shanghai Futures Exchange warehouses. As regional pricing premiums widen and trade flows skew disproportionately toward the United States, prolonged tariff uncertainty risks transforming temporary arbitrage plays into a permanent, structural fracture in the global copper market.

South Africa’s International Trade Administration Commission (ITAC) has proposed expanding the country’s automotive incentive framework to include minerals used in electric-vehicle battery manufacturing, supporting deeper localisation of the domestic automotive and battery-material supply chains. Under the proposal, the existing list of eligible standard materials including aluminium, steel and platinum-group metals would be expanded to cover lithium, graphite, cobalt, copper, iron and rare earths. Eligible materials would need to originate from member states of the Southern African Customs Union (SACU) or Southern African Development Community (SADC). The proposed framework would recognise 50% of the value of qualifying EV battery materials as local content, potentially improving producers’ eligibility for automotive-sector incentives. The policy aligns with the South African Automotive Master Plan 2035, which aims to increase vehicle production, local content and investment as the industry transitions toward electric mobility. Stakeholders were given four weeks from the notice date to submit comments, meaning the final scope and implementation schedule remain subject to consultation. SMM comments: The proposal represents a demand-side approach to developing Africa’s battery supply chain, contrasting with Zimbabwe’s supply side policy of restricting concentrate exports to force domestic processing. If implemented, South Africa could emerge as a regional battery material processing or manufacturing hub sourcing feedstock from neighbouring SADC producers, including Zimbabwe and Namibia. However, the near-term impact on regional lithium trade flows is likely to be limited. Major Zimbabwean lithium assets including Arcadia, Bikita and Sabi Star are controlled by Chinese companies with established China-linked processing and offtake arrangements. It also remains unclear whether spodumene concentrate would qualify directly as an eligible battery material or whether further conversion into lithium sulphate, carbonate or hydroxide would be required. The final rules should therefore be monitored alongside Zimbabwe’s planned January 2027 lithium concentrate export deadline, as the two policies could influence future investment and trade flows within Southern Africa.

[SMM Research] Nigeria remains a key supplier of tantalum concentrate, with exports largely priced on an FOB basis and driven by strong Chinese demand. Concentrate grades vary widely, with higher Ta₂O₅ content commanding significant premiums. Artisanal mining dominates supply, while informal trade continues to limit market transparency. SMM's research indicates that first-hand market intelligence remains essential for assessing pricing, quality and evolving supply chains.

[SMM Analysis: US and Europe Expand Copper Recycling Capacity as Scrap Localisation Takes Shape]The US and Europe are expanding recycling capacity and tightening resource policies to retain more copper scrap locally. Aurubis projects in Hamburg and Georgia will increase complex-feedstock processing, while export controls may further limit trade flows. Asian buyers could face higher payabilities, longer lead times and tighter supply.

Following the start of the definitive phase of the EU Carbon Border Adjustment Mechanism (CBAM) in 2026, differences in country-specific default values , default production routes and corresponding benchmarks have begun to translate into significantly different theoretical certificate exposures for unwrought aluminium. SMM analysed EU-27 imports of unwrought aluminium under HS/CN 7601 from non-EU origins and matched the trade data with the 2026 default value, default production route and CBAM benchmark assigned to each origin. The theoretical unit certificate exposure in this analysis is calculated as: 2026 theoretical unit certificate exposure = 2026 default value − benchmark × 97.5% × cross-sectoral correction factor The cross-sectoral correction factor, or CSCF, is provisionally assumed to be 1. The calculation does not deduct any qualifying carbon price effectively paid in the country of origin. The results therefore indicate the relative CBAM exposure of different origins under the default-value scenario. They do not represent the final number of certificates that EU importers will be required to surrender or the final monetary cost. EU-27 unwrought aluminium imports rose 7.0% in 2025 According to SMM calculations, EU-27 imports of unwrought aluminium under HS/CN 7601 from non-EU origins reached approximately 7.63 million tonnes in 2025 , up from 7.13 million tonnes in 2024. This represented an increase of about 502,200 tonnes, or 7.0% year on year . Of the 2025 total, approximately 4.56 million tonnes originated from countries subject to CBAM, accounting for 59.7% of total imports. Imports from CBAM-exempt origins, including Norway, Iceland and Switzerland, amounted to approximately 3.05 million tonnes , representing around 40.0% of the total. A further 25,800 tonnes were recorded without a specified origin and were excluded from the country-level exposure ranking. Applying the 2026 default values and benchmarks to the 2025 trade structure produces an estimated theoretical certificate exposure of approximately 4.09 million tCO₂e for imports from CBAM-covered origins. The trade-weighted average unit exposure was approximately 0.898 tCO₂e per tonne of product . As 2025 remained within the CBAM transitional period, these figures are scenario-based estimates using 2025 trade volumes and the 2026 calculation rules. They do not represent actual certificate obligations for 2025. Primary aluminium route accounted for more than 99% of theoretical exposure The primary aluminium route dominated both CBAM-covered import volumes and theoretical certificate exposure. In 2025, imports assigned to the primary aluminium route totalled approximately 4.46 million tonnes , accounting for 97.8% of imports from CBAM-covered origins. Their theoretical certificate exposure reached approximately 4.06 million tCO₂e , representing 99.3% of the total exposure. The trade-weighted average unit exposure for the primary aluminium route was approximately 0.912 tCO₂e per tonne of product . By comparison, imports assigned to the secondary aluminium route amounted to approximately 99,500 tonnes, or 2.2% of CBAM-covered imports. Their theoretical certificate exposure was approximately 30,600 tCO₂e, with an average unit exposure of around 0.307 tCO₂e per tonne . The gap between the two routes reflects differences in both country default values and the applicable benchmarks. For HS/CN 7601, the benchmark used for the primary aluminium route is 1.423 tCO₂e per tonne , compared with 0.091 tCO₂e per tonne for the secondary aluminium route. This means that, under a default-value declaration scenario, the theoretical CBAM exposure of EU-27 unwrought aluminium imports remains highly concentrated in primary aluminium supply. Mozambique recorded the highest unit exposure, with China also ranking near the top The results show a clear divergence in theoretical unit exposure among origin countries. Mozambique recorded the highest unit exposure among major origins with a country-specific default value, at approximately 2.130 tCO₂e per tonne of product . China followed at approximately 1.913 tCO₂e per tonne , placing it among the origins with the highest default-value-based unit exposure. South Africa recorded an estimated unit exposure of approximately 1.207 tCO₂e per tonne , followed by Russia at 0.989 tCO₂e and Canada at 0.769 tCO₂e. Bahrain, the United Arab Emirates, India, the United Kingdom, Egypt and Kazakhstan share similar default values under the primary aluminium route, resulting in unit exposure of approximately 0.670 tCO₂e per tonne . Australia, Brazil, Malaysia, Oman, Qatar, Saudi Arabia and the United States recorded unit exposure of approximately 0.483 tCO₂e per tonne . Origins assigned to the secondary aluminium route generally recorded approximately 0.307 tCO₂e per tonne . A high unit exposure does not necessarily mean that an origin faces the greatest aggregate impact. Total exposure also depends on the volume of trade with the EU-27. China illustrates this distinction. EU-27 imports of HS/CN 7601 products from China reached approximately 12,400 tonnes in 2025 , up 24.3% year on year. This corresponded to theoretical certificate exposure of about 23,700 tCO₂e . China therefore ranked near the top on a unit basis, but its comparatively limited shipment volume to the EU-27 kept its aggregate exposure well below that of Mozambique, Canada and several major Gulf suppliers. Mozambique’s total theoretical exposure reached 1.34 million tCO₂e After incorporating 2025 import volumes, Mozambique emerged as the origin with the highest aggregate theoretical certificate exposure. EU-27 imports from Mozambique reached approximately 628,000 tonnes in 2025 , up 17.5% year on year. Based on unit exposure of 2.130 tCO₂e per tonne, its total theoretical exposure was approximately 1.34 million tCO₂e . Mozambique alone accounted for 32.7% of the theoretical exposure associated with CBAM-covered origins. However, the above total exposure is a static estimate based on 2025 trade volumes. Power supply constraints may limit Mozambique’s aluminium smelting capacity and output in 2026–2027, potentially reducing its exports to the EU. As a result, its actual near-term aggregate CBAM exposure may not reach the theoretical level estimated using 2025 trade volumes. Canada supplied approximately 682,800 tonnes to the EU-27 in 2025. Although its unit exposure was considerably lower than Mozambique’s, its larger trade volume lifted its aggregate theoretical exposure to approximately 524,800 tCO₂e , equivalent to 12.8% of the total. Bahrain, the United Arab Emirates, Russia and South Africa recorded theoretical total exposures of approximately 350,900 tCO₂e, 329,300 tCO₂e, 322,200 tCO₂e and 263,600 tCO₂e, respectively. Mozambique, Canada, Bahrain, the United Arab Emirates, Russia and South Africa together accounted for approximately 76.4% of total theoretical certificate exposure. Mozambique’s position was driven by the combination of a high unit default-value exposure and substantial trade volume. Canada’s unit exposure was not among the very highest, but its large and rapidly increasing export volume significantly amplified its aggregate impact. Four-quadrant analysis places China in the “high intensity, low trade volume” category A four-quadrant analysis using 2025 EU-27 import volume on the horizontal axis and 2026 theoretical unit certificate exposure on the vertical axis provides a clearer view of the combined influence of carbon intensity and trade scale. The core high-exposure quadrant includes Mozambique, Canada, Bahrain, the United Arab Emirates, Russia, South Africa, India and the United Kingdom. These origins combine comparatively large trade volumes with relatively high unit exposure and are the main contributors to aggregate CBAM exposure for EU-27 unwrought aluminium imports. China is the most prominent origin in the high intensity, low trade volume quadrant . Its theoretical unit exposure of approximately 1.913 tCO₂e per tonne is second only to Mozambique, but its current export volume to the EU-27 remains comparatively limited. Ukraine and South Korea are among the origins in the trade-volume-driven quadrant . Both are assigned to the secondary aluminium route and have relatively low unit exposure, but their larger trade volumes increase their aggregate exposure compared with other secondary-route origins. Vietnam, Morocco, Serbia, Bolivia and Mexico are among the origins in the low-exposure quadrant , reflecting both lower unit exposure and limited trade volumes. For Vietnam, HS/CN 7601 unwrought aluminium is assigned to the secondary aluminium default route, resulting in theoretical unit certificate exposure of approximately 0.307 tCO₂e per tonne in 2026, significantly below that of most origins assigned to the primary aluminium route. EU-27 imports from Vietnam amounted to approximately 7,100 tonnes in 2025, down around 27.1% year on year, corresponding to theoretical total certificate exposure of about 2,200 tCO₂e. Vietnam’s overall CBAM exposure therefore remains relatively limited at present. However, should its exports to the EU expand in the future, access to and verification of actual emissions data will remain an important factor affecting the relative competitiveness of Vietnamese products. The quadrant thresholds are analytical dividing lines based on the median values of CBAM-covered origins with actual trade. They do not represent regulatory thresholds set by the EU. Theoretical exposure reached approximately 642,400 tCO₂e in Q1 2026 In the first quarter of 2026, EU-27 imports of unwrought aluminium under HS/CN 7601 from non-EU origins reached approximately 1.52 million tonnes , with a total import value of around €4.36 billion . The average import value was approximately €2,873 per tonne . Imports from CBAM-covered origins amounted to approximately 782,800 tonnes , accounting for 51.6% of total imports. Imports from CBAM-exempt origins reached around 733,000 tonnes, or 48.4%. Based on the 2026 default values and benchmarks, imports from CBAM-covered origins generated theoretical certificate exposure of approximately 642,400 tCO₂e during the quarter. Mozambique remained the largest contributor, with theoretical exposure of around 150,500 tCO₂e. Canada followed with approximately 86,800 tCO₂e, the United Arab Emirates with 82,100 tCO₂e, Bahrain with 63,400 tCO₂e and South Africa with 56,200 tCO₂e. As the analysis does not include Q1 2025 comparison data, no year-on-year conclusion has been drawn for Q1 2026 import volumes or exposure. The quarterly figures are used primarily to illustrate the origin structure during the initial stage of the definitive CBAM period. Access to and verification of actual emissions data could become an important competitiveness factor Country default values are fallback parameters applied when producers are unable to provide actual emissions data that meet EU requirements. They do not necessarily reflect the actual carbon intensity of a specific producer or shipment. For origins with relatively high default-value exposure, including China, Mozambique, South Africa and Russia, producers whose actual embedded emissions are materially lower than the applicable country default value could reduce the certificate exposure faced by EU importers by establishing robust emissions-monitoring systems and providing complete, verified emissions data. Conversely, where suppliers are unable to provide emissions information that is complete, traceable and compliant with EU requirements, importers may have to rely on the relevant country default value. A higher default value could consequently affect supplier selection, purchase negotiations and long-term contract arrangements. The final number of certificates to be surrendered will also depend on actual embedded emissions, production-route classification, data verification and any qualifying carbon price effectively paid in the country of origin. The actual CBAM cost will additionally depend on the CBAM certificate price, which is linked to EU Emissions Trading System allowance prices. The theoretical certificate exposure calculated in this analysis should therefore not be interpreted directly as either the final certificate obligation or the final CBAM cost. Overall, the impact of CBAM on trade in HS/CN 7601 unwrought aluminium will not be determined by country default values alone. Unit certificate exposure, trade scale, actual emissions and the availability of reliable carbon data will jointly shape the competitive position of different origins and producers in the EU market. As the definitive phase progresses, differences in low-carbon production capability, emissions-data management and verification capacity are likely to become increasingly visible in procurement decisions, export competitiveness and trade flows. Data note: The trade scope covers EU-27 imports of unwrought aluminium under HS/CN 7601 from non-EU origins. CBAM-exempt origins, including Norway, Iceland and Switzerland, are included in total import statistics but excluded from theoretical certificate exposure. Origins without a country-specific default value are assigned the applicable value for “Other Countries and Territories.” Unspecified origins are excluded from the country ranking. Theoretical exposure does not deduct qualifying carbon prices paid in third countries. Source: EU-27 import data, EU CBAM default values and benchmarks; compiled by SMM.
