Guinea-China bauxite freigh rates have rebounded recently amid renewed volatility in the Middle East and continued tightness in the dry bulk shipping market. As at least 70% of Guinea’s bauxite shipments are destined for China, sustained high freight rates on the Guinea-China route have not only lifted delivered logistics costs but also constrained shipments through weaker margins and limited vessel availability. Freight rose much faster than CIF prices, briefly accounting for over half of delivered prices SMM data showed that Guinea-China bauxite freight rates rose from $23.50/wmt on February 27 to $36.75/wmt on May 29, an increase of 56.4%. Freight remained at the same elevated level in the week ending June 5. Over the same period, the weekly average SMM Guinea bauxite CIF China price rose from $60.00/wmt to $68.00/wmt, an increase of only 13.3%, significantly lagging the rise in freight. As a result, freight as a share of the SMM Guinea bauxite CIF China price increased from 39.17% to 54.04%, meaning that ocean freight at one point represented more than half of the assessed delivered price. With CIF prices unable to fully absorb the additional shipping costs, pressure on miners’ and traders’ operating margins continued to build. According to SMM market contacts, the vast majority of surveyed Guinean mines reduced shipments to varying degrees after freight rates remained elevated, while some mines temporarily suspended loadings. High freight costs have therefore become a major direct factor behind the recent slowdown in Guinea’s bauxite shipments. In addition to prices, tight vessel availability has also restricted physical shipments. Traders and miners have widely reported difficulties securing spot bulk carriers, particularly for prompt cargoes. Some shipments have been delayed even where participants were prepared to accept prevailing freight levels, as vessels could not be secured in time and loading schedules had to be postponed. Peak season and contractual obligations initially supported March-April shipments Despite the sharp rise in Guinea-China freight rates from March, Guinea’s bauxite shipments remained relatively high during March and April. March-April is traditionally a peak shipment period in Guinea, when mining, inland transport and port-loading conditions are relatively favourable. In addition, previously signed long-term contracts and vessels booked in advance still had to be fulfilled. At the beginning of the freight rally, many market participants also expected the increase to be temporary. Miners therefore did not immediately make broad adjustments to existing shipment plans. SMM data showed that average weekly bauxite shipments from Guinea stood at 4.98 million mt between March 6 and April 24. Shipments remained high even after freight exceeded $30/wmt, reaching a weekly peak of 6.15 million mt in the week ending April 3. However, as elevated freight rates persisted into late April and May, the support from existing contracts, previously arranged vessels and the seasonal shipment peak gradually weakened. The impact of shipping costs became increasingly visible in outbound volumes. Average weekly shipments fell to 4.00 million mt between May 1 and June 26, down 19.8% from the March 6-April 24 average. Monthly data showed a similar trend. Guinea shipped 17.50 million mt in May, down 18.5% month on month, before shipments declined by another 10.0% to 15.74 million mt in June. The timing of the decline broadly coincided with the prolonged period of high freight rates and increasingly tight spot vessel availability reported by market participants since late April. Freight pressure eased briefly in late June before returning in July Shipping-market pressure eased temporarily in the second half of June as more positive expectations emerged around Middle East negotiations. Guinea-China bauxite freight rates fell from $36.75/wmt on June 5 to $31.00/wmt on July 3, while freight as a share of the SMM Guinea bauxite CIF China price declined from 54.04% to 43.66%. However, shipments did not recover immediately. Restarting cargo programmes, securing vessels and reorganising loading schedules all require time. Guinea was also moving deeper into its rainy season, further limiting the speed of any recovery. The rainy season generally runs from May to November, with the impact becoming more pronounced in July and August. SMM market feedback suggests that rainfall may reduce shipments by around 20% during the most disruptive period by affecting mine-to-port transportation, barge operations and loading efficiency. Entering July, renewed escalation in the Middle East pushed Guinea-China freight rates higher again. Freight rose from $31.00/wmt on July 3 to $35.00/wmt on July 24, an increase of 12.9%. Over the same period, the weekly average SMM Guinea bauxite CIF China price edged down from $71.00/wmt to $70.50/wmt, lifting the freight share back to 49.65%. According to SMM market contacts, as freight rates rebounded and spot bulk carriers remained difficult to secure, some mines that had previously planned to resume shipments again reduced or suspended loadings. Weekly shipments declined from 3.41 million mt in the week ending July 3 to 3.07 million mt in the week ending July 24, a decrease of 9.9%. Shipments fell as low as 2.83 million mt in the week ending July 17. As of July 24, Guinea’s cumulative July shipments stood at 10.55 million mt, equivalent to an average of 439,500 mt per day, down 16.2% from June’s daily average. SMM outlook SMM believes that the recent pressure on Guinea’s bauxite shipments cannot be attributed solely to seasonal rainfall. Persistently high freight rates and tight spot vessel availability have become the main direct constraints on shipments, while the rainy season has amplified the disruption. High freight rates continue to compress the operating room available to miners and traders, while scarce vessel availability is preventing some cargoes from progressing from planned sales to actual loading. The traditional shipment peak, contractual obligations and previously arranged vessels delayed the transmission of higher freight costs into shipment volumes during March and April. However, as elevated freight rates persisted, the vast majority of surveyed miners gradually reduced shipments, while some temporarily halted loadings, with the impact becoming increasingly apparent from May. In the near term, developments in the Middle East, fuel costs and dry bulk vessel availability in the West African market will remain key factors influencing Guinea-China freight rates. Should freight rates remain near $35/wmt or rise further, while tight spot bulk carrier availability shows no meaningful improvement, Guinean miners’ willingness to ship and their actual loading capacity may remain constrained. Combined with the impact of the July-August rainy season on mine-to-port transportation, barge operations and port-loading efficiency, Guinea’s weekly bauxite shipments are expected to remain volatile at relatively low levels, with marginal mines and spot cargoes facing greater pressure. Looking ahead to the third quarter of 2026, under SMM’s base-case scenario of persistently high freight rates, tight vessel availability and continued rainy-season disruption, Guinea’s bauxite shipments are expected to remain subdued and fluctuate at low levels. Average daily shipments may mainly range between 370,000 mt and 400,000 mt, corresponding to monthly shipments of approximately 11.5 million-12.0 million mt, broadly in line with the monthly average recorded in the third quarter of 2025. Shipments could stage a temporary recovery should Middle East tensions ease, freight rates decline significantly and bulk vessel availability improve. Meanwhile, developments concerning Guinea’s bauxite export quota policy remain a key uncertainty for the supply outlook. Any substantive implementation of related measures could further alter the pace of shipments and expectations for the country’s total bauxite exports.

SMM News on July 30: Domestic Bauxite: Supply Disruptions Drive Up Domestic Ore Prices; Alumina Refineries' Long-Term Contract Procurement Prices Rise Overall Affected by coking coal-related incidents in Shanxi, mining activities in major domestic bauxite producing areas like Shanxi and Henan have been somewhat disrupted in the short term, leading to phased changes in ore supply. Meanwhile, alumina prices remain at relatively high levels, and alumina refineries have a moderate tolerance for rising raw material costs, mostly accepting current ore prices passively in the near term. As of today, the EXW price, excluding VAT, at crushing plants for bauxite with an Al/Si ratio of 5.0 and 60% alumina content in Shanxi is approximately 530-550 yuan/mt; in Henan, the EXW price for similar bauxite is around 500-540 yuan/mt; in the Guiyang area, the EXW price, including VAT, for bauxite with an Al/Si ratio of 6.0 and 60% alumina content is 490-540 yuan/mt; and in Guangxi, the EXW price, excluding VAT, for bauxite with an Al/Si ratio of 6.0 and 53% alumina content is 320-335 yuan/mt. Imported Bauxite: Ocean Freight Rates Fluctuate at Highs; August Long-Term Contract Prices Yet to Be Settled; Imported Bauxite Market Remains in a State of Continued Negotiation According to data from July 24, total weekly port departures of bauxite from major ports in Guinea were 3.0697 million mt, up 237,700 mt from the previous week, with shipments edging up slightly. As US-Iran tensions intensify again, oil prices have rebounded, and ocean freight rates from Guinea to China have followed suit with a rising trend, with market quotations reaching around $35/mt, driving up mine costs to varying degrees. Coupled with policy uncertainties in Guinea and weather-related transport disruptions, Guinean mines are tightening control over bauxite shipments. In Australia, as of July 24, total weekly bauxite port departures from major Australian ports were 1.0481 million mt, up 326,800 mt from the previous week, with shipments rising slightly; the future pace of shipments from Australian mines and changes in port departures require further attention. As of July 24, China's bauxite port arrivals stood at 2.7603 million mt, down 1.9029 million mt from the previous week. Continued attention is needed on the impact of high and fluctuating oil prices and ocean freight rates on future arrival pace and landed costs. In terms of prices, Guinean bauxite long-term contract offers for July are in the range of $70-71.5/mt, while August long-term contract prices are still under negotiation. Meanwhile, bauxite inventories at domestic alumina refineries remain at high levels. This week, alumina refinery bauxite inventories were relatively stable, with days of inventories at about 94 days, exerting some downward pressure on ore prices. As for Guinean bauxite, with the rebound in Guinean-to-China transportation costs, mine costs, plus shipment reductions caused by the traditional rainy season and adverse weather, upstream and trader offers remained firm and held steady in the high price range of $70-72/mt. Due to persistently high inventory at domestic alumina refineries and shrinking profits, the intended transaction price dropped to $70/mt or lower. The upstream and downstream bauxite market saw significant price divergence, with transaction activity slowing down, and the tug-of-war continued from the previous week. As of Thursday this week, Guinean bauxite FOB quotes were $38-40/mt, with the average price unchanged from the previous Thursday; CIF prices were reported at $69-73/mt, with the average up $0.5/mt from the previous Thursday; the SMM Imported Bauxite Index stood at $70.87/mt, up $0.51/mt from the previous Thursday. Future bauxite prices will still depend on mine cost conditions, Guinea’s traditional rainy season, and the impact of the Guinean government’s bauxite export quota policy on overall shipments. SMM will continue to closely monitor bauxite market trends and transactions. Overall , the domestic ore market price maintained the current level; meanwhile, inventory at domestic alumina refineries remained high (about 94 days), and buyers and sellers continued to bargain over offers. Uncertainty over Guinea’s quota policy, declining shipments, and the traditional rainy season also exerted some upward pressure on bauxite costs. In the short term, as shipment volumes decline due to both costs and policy factors, imported ore prices are expected to maintain their high-level tug-of-war pattern. Afterwards, close attention should be paid to the implementation of Guinea’s quota policy and the trend in ocean freight rates.

Silica: This week, silica prices remained stable overall. Supply side, affected by weather and other seasonal factors in some producing areas, the mining pace at mines slowed, leading to a temporary reduction in ore supply, which lent support to local markets. However, overall silica ore reserves were ample and cross-regional flows relatively sufficient, so the overall supply landscape remained loose. Demand side, the silicon metal market continued to consolidate at lows, with industry profits under pressure. Downstream silicon plants maintained only monthly just-in-time procurement orders for raw materials and strictly controlled procurement costs. In the short term, silica prices are expected to remain steady. Silicon coal: This week, the silicon coal market saw regional divergence, with the price in Shaanxi slightly lowered by 15 yuan/mt to 820-850 yuan/mt, while quotes in other regions remained stable for now. Demand side, production resumptions during the rainy season in south-west China boosted downstream silicon plants' operating rates, leading to a marginal rebound in just-in-time procurement volumes of silicon coal. However, support was limited, so the demand boost remained weak. Supply side, coal processing plants whose main product is coking coal continued to produce silicon coal according to orders, with no inventory pressure, while those mainly exporting silicon coal faced slow shipments and significant inventory pressure amid weak overall demand, resulting in a supply-demand mismatch pattern for the industry. Cost side, upstream coking coal prices have recently shown signs of softening, which will weaken cost support; thus, the silicon coal market is expected to be in the doldrums in the short term. Petroleum coke: This week, trading in China's petroleum coke market was active, with prices of petroleum coke across specifications all rising. Port spot transactions of Formosa Plastics petroleum coke diverged, with mainstream prices still at 1,450-1,500 yuan/mt. According to SMM, as of this Thursday, the Shandong 4# petroleum coke price index was reported at 2,093.05 yuan/mt, up 4.46% WoW. Recently, domestic refinery operations have been stable, procurement enthusiasm on the demand side remained moderate, and coupled with external geopolitical disruptions, petroleum coke prices are expected to consolidate on a strong note in the short term. Electrode: This week, electrodes used in silicon production remained at low prices. Supply side showed structural divergence: major producers, with captive downstream silicon plants, mainly supplied for self-use, so their inventory and shipment pressure were relatively manageable. In contrast, small and medium-sized electrode producers faced intense competition, and with the overall sluggish silicon metal market, downstream small and medium silicon plants operated at low loads, had limited orders, slow shipments, and in-factory inventory pressure. Demand side, although silicon metal production increased MoM in July, electrodes account for a relatively small proportion of smelting unit consumption, with rigid and inelastic demand; thus, downstream procurement mainly met rigid demand to maintain normal production, with limited actual growth, making it difficult to effectively boost the market. Under the dual influence of supply and demand, prices of electrode used in silicon production will remain consolidating at lows.
