Bunker Fuel Supplier at Zhoushan

Zhoushan has been the fastest-growing major bunker hub of the past decade, climbing to approximately 7.0 million tonnes in 2024 — fourth globally. The port's rise was driven by China's establishment of the Zhejiang Pilot Free Trade Zone, which permits bonded (duty-free) bunker sales to international vessels, combined with aggressive infrastructure investment.

Port Detail

Bonded fuel and policy tailwinds

Until the mid-2010s, international bunkering in China was constrained by tax treatment. The free trade zone regime made bonded fuel commercially viable at Zhoushan, and state-backed suppliers — notably China Marine Bunker (Chimbusco) — built scale rapidly. In 2024, Chimbusco became the world's largest marine fuel supplier by volume.

Integration with Ningbo-Zhoushan

The combined Ningbo-Zhoushan port is the world's largest by cargo tonnage. Bunker operations are distributed across the archipelago, with dedicated anchorages at strategic points. Vessels calling container terminals at Ningbo-Zhoushan can efficiently bundle bunkering with cargo operations.

Fuels available

VLSFO and HSFO are standard; LSMGO for ECA and auxiliary use is widely supplied. China has designated Domestic Emission Control Areas (DECAs) that impose a 0.10% sulphur cap within 12 nautical miles of shore — LSMGO demand inside DECAs is accordingly high. LNG infrastructure is expanding; biofuel trials have commenced.

What to expect operationally

Documentation is in Chinese and English; commercial dealings with international suppliers are straightforward. Winter weather (November-March) can bring short weather delays from northerly winds. Typical nomination lead time is 3-5 days.
