Tank storage China holds an estimated 1.8 billion barrels of onshore crude oil capacity — a figure that makes it the single largest above-ground bulk liquid storage system in the world. State-owned enterprises (SOEs) account for roughly 70% of that capacity, with the remainder leased through independent third-party terminals. Beijing has ordered a further 169 million barrels across 11 new reserve sites since 2024, driven by energy security policy and a need to buffer against disruption in key transit straits.
Tank Storage China: Market Structure and Key Operators
The Chinese tank storage market divides into two operational frameworks. SOEs — Sinopec, CNPC, PetroChina, Sinochem, and CNOOC — manage the majority of capacity, combining commercial crude storage with Strategic Petroleum Reserves (SPR) under a unified national energy law. A 2024 regulation formalised state control over both government-held strategic stocks and corporate “social responsibility” reserves during supply emergencies.
Independent and third-party operators control approximately 45% of overall leasing capacity. Domestic logistics companies such as Zhoushan Jinrun and Zhuhai Winbase operate alongside international operators including Vopak and Sea-Invest, which lease tank space to international trading counterparties. The Port of Zhoushan has fully digitised commercial tank availability data, with traders able to view real-time capacity and pricing tiers via the Zhejiang International Oil and Gas Trading Center.

Major Tank Storage China Hubs and Terminal Locations
China’s terminal network exceeds 600 locations containing approximately 16,000 active tanks, heavily concentrated along the coast near deepwater berths and mega-refineries.
| Hub | Province / Region | Primary Products |
|---|---|---|
| Zhoushan Port Cluster | Zhejiang | Crude oil, low-sulphur bunker fuel, refined products |
| Qingdao LNG / Crude Terminal | Shandong | Crude oil, LNG (mega-scale) |
| Dalian Liquids Terminal | Liaoning | Chemicals, crude oil, refined petroleum products |
| Tianjin Port Terminals | Tianjin Municipality | Heavy crude, petroleum feedstocks |
| Zhuhai Winbase Terminal | Guangdong | Chemicals, refined products |
| Yancheng Hub | Jiangsu | Natural gas stockpiles |
Zhoushan remains the dominant crude trading hub on the eastern seaboard. The Qingdao terminal at Shandong province serves both crude imports and mega-scale LNG storage — Sinopec commissioned a 270,000 cubic metre LNG tank at Qingdao in 2023, with a tank diameter of 100.6 metres, which was the largest single LNG storage vessel in China at the time of commissioning.
2026 Expansion: Underground Caverns and Mega-Scale LNG
China’s capacity buildout in 2025-2026 is running at an unusually fast pace. The 169 million barrels of new reserve storage added across 11 new sites matches the combined total built over the previous five years. Above-ground construction is running in parallel with a structural shift toward underground rock cavern storage.
Fujian province is advancing a 31 million cubic metre (approximately 195 million barrel equivalent) underground oil storage network designed for strategic reserve protection. Underground caverns offer protection against aerial threats and reduce evaporation losses on light products — a cost and security consideration that has become more prominent in Chinese strategic planning since 2022.
On the LNG side, CNOOC is building 11 additional 270,000 cubic metre tanks at its Zhuhai and Zhejiang terminals, matching the Sinopec Qingdao specification. These are targeted at supporting urban heating demand during peak winter periods — a load profile that creates sharp seasonal draw requirements on LNG storage.

Tank Storage China: Regulatory Framework and SPR Policy
China’s energy storage regulation operates under the National Energy Law framework, which mandates both government-held strategic reserves and corporate social responsibility reserves under a single unified structure. During declared supply emergencies, state authorities can direct the drawdown of both. This creates a blended public-private reserve system with no direct equivalent in OECD markets.
The International Energy Agency (IEA) tracks Chinese SPR data on a voluntary basis; China is not an IEA member, and official disclosure of SPR volume and drawdown levels remains limited. Market estimates for Chinese onshore inventories range between 1.13 and 1.4 billion barrels on any given date, equivalent to approximately 100-130 days of net import cover, according to reporting from the US Energy Information Administration.
Tank Storage China and the Asia-Pacific Market
China functions as the dominant volume anchor for tank storage across the wider Asia-Pacific region. Its crude import levels — consistently above 10 million bpd — drive terminal throughput at both Chinese ports and regional hubs such as Fujairah, Singapore, and South Korean import terminals. The Korean crude import market, for example, has responded directly to Chinese refinery run-rate signals throughout 2025-2026.
Independent terminal operators with Chinese assets are increasingly relevant to global traders seeking flexibility outside the SOE system. The third-party leasing segment — approximately 45% of total capacity — provides the access points that international counterparties use for cargo optimisation and blending.

How large is tank storage in China?
China’s onshore crude oil storage capacity is estimated at over 1.8 billion barrels, the largest in the world. Current onshore inventories are estimated to range between 1.13 and 1.4 billion barrels at any given time, equivalent to approximately 100–130 days of net import cover.
Who are the main tank storage operators in China?
State-owned enterprises dominate, with the “Big Five” — Sinopec, CNPC, PetroChina, Sinochem, and CNOOC — controlling around 70% of capacity. Independent third-party operators, including domestic companies such as Zhoushan Jinrun and Zhuhai Winbase, account for approximately 45% of leasing capacity. International operators including Vopak and Sea-Invest also lease space in the Chinese market
Where are China’s main tank storage hubs located?
The principal hubs are Zhoushan (Zhejiang province), Qingdao (Shandong), Dalian (Liaoning), Tianjin, Zhuhai Winbase (Guangdong), and the Yancheng natural gas cluster in Jiangsu. All are coastal locations with access to deepwater berths.
What is China building for tank storage in 2026?
China is constructing 169 million barrels of new strategic reserve storage across 11 sites — matching the total built over the previous five years. Sinopec and CNOOC are also expanding mega-scale LNG tank capacity at Qingdao, Zhuhai, and Zhejiang using 270,000 cubic metre tank designs. Fujian province is advancing a 31 million cubic metre underground oil storage network
Does China store crude oil in underground caverns?
Yes. China is expanding underground rock cavern storage as part of its strategic reserve programme. The most advanced project is in Fujian province, targeting 31 million cubic metres of capacity. Underground storage provides protection against aerial threats and reduces evaporation losses on light petroleum products.
