Regulations from the US Trade Representative (USTR) that start this fall could prompt a major shift in shipping patterns that drives up the cost of imports, according to ship brokers. The burden falls on ship owners and fleet operators to pay a fee on laden, Chinese-built vessels discharging cargo at US ports. For Chinese vessel owners and operators, the fee will start in mid-October at $50 per net ton and rise to $140/ton by mid-April of 2028. For non-Chinese operators using Chinese-built vessels in their fleets, the fees start at $18/ton and rise to $33/ton over the same period. The fees can be imposed up to five times annually per ship.
