Ten Weeks Left on the China-US Port Fee Truce as the 9 November Deadline Nears
Both sets of measures snap back automatically unless a new bilateral arrangement is concluded
With approximately ten weeks remaining before the suspended China-US port fee measures expire, operators on trans-Pacific trades face a renewed period of cost and compliance uncertainty.
The measures trace their origins to April 2025, when the Office of the United States Trade Representative opened a Section 301 investigation into China's maritime, logistics and shipbuilding sectors. Following that investigation, the United States implemented port fee measures on 14 October 2025.
China's Ministry of Commerce responded within days, characterising the action as unilateralism and protectionism in violation of World Trade Organization rules and of the reciprocity principles set out in the China-US Maritime Transport Agreement. Beijing then imposed special port dues on vessels carrying US elements, a definition drawn broadly enough to capture US flag, US construction, US ownership, US equity participation or US operation.
A new economic and trade arrangement followed in November 2025. On 9 November the USTR announced the suspension, effective from 10 November, of its Section 301 measures targeting China's maritime, logistics and shipbuilding sectors for a period of one year. China suspended its countermeasures at the same time, with its Ministry of Transport confirming that from 13:01 on 10 November 2025 the special port dues and associated retaliatory measures against US-linked vessels would be paused for twelve months. Under those terms, 9 November 2026 is the scheduled expiration date.
If the suspension lapses without a replacement agreement, the US measures previously applied to China-related vessels could resume. Applicability is not settled by flag alone. The framework works through a vessel's ownership structure, its operational relationships and its country of construction, which means a ship's exposure can differ from what its register suggests.
China's special port dues on vessels with US elements remain suspended on the same clock. If no new arrangement is concluded before the November deadline, both sets of previously suspended measures carry a meaningful probability of reinstatement.
For operators the practical consequence is that ownership attribution, operator identity and build origin return as variables in route deployment and cost modelling rather than as background detail. Those questions run through the beneficial owner rather than the registered owner, and on a trans-Pacific string they determine which hull is worth sending to which port in the first weeks of November.
