2026 US Rules on Ocean Freight Surcharges for China Shipments: Complete Guide to Cost Calculation for US-China Route Exports

Mr.Miao,the general manager of a hardware export factory in Songjiang,Shanghai,consulted last week: the shipping company designated by his US West customer suddenly added a "China-targeted Ocean Shipping Adjustment Fee" of 160 USD/TEU,which was not mentioned in the previous booking quote.The entire shipment of 20 containers directly increased the cost by 3200 USD,almost wiping out the entire order’s profit.This is not an isolated case.Since 2026,the US route ocean freight charge rules have been adjusted frequently,and many export enterprises have vague understanding of the nature,responsible party,and calculation logic of various targeted charges,with a pitfall rate exceeding 40%.

Core Categories of US Ocean Shipping Charges for China Shipments in 2026

First,it is clear: all types of charges imposed by the US on China ocean shipping are essentially logistics surcharges collected by shipping companies or US ports,not tariffs or anti-dumping duties,and cannot be included in the export tax rebate declaration base.The current mainstream charge items are as follows:

Common Misunderstandings and Risk Warnings

Most export enterprises have obvious deviations in understanding US route ocean freight charges,with core risks concentrated in three categories:

• Confusing charge nature: including ocean freight surcharges in export tax rebate declaration base.Many enterprises mistakenly treat targeted adjustment fees as taxes and illegally include them in input tax deduction.After triggering tax bureau inspection,they not only have to transfer out the tax but also pay 0.5-5x late fees.
• Ignoring responsible party agreement: being deducted shipper’s deposit by shipping companies under FOB terms.Nearly 30% of shipping companies directly deduct targeted adjustment fees and congestion fees from the booking party’s deposit.Without clear agreement in trade contracts,enterprises take at least 3 months to recover fees,and some small fees are irrecoverable.
• Intentionally underdeclaring cargo value to reduce surcharge base.For surcharges based on cargo value proportion,underdeclaration triggers US CBP price assessment,leading to supplementary payment of difference fees plus 50 USD/container/day detention fees; severe cases result in inclusion in US route import/export blacklist.

Practical Guide to Avoiding Pitfalls

In 2026,we handled a refund dispute for a mechanical equipment export enterprise in Suzhou.Its 25 containers to US West LAX port were supplementary charged 150 USD/TEU targeted adjustment fee by the shipping company.We retrieved stamped booking quote details and FOB terms in trade contracts,helping the enterprise recover all overcharged 3750 USD in 7 days.Based on practical experience,three actionable suggestions:

First,before booking,require shipping agents to issue fully stamped fee details.All verbal fee reduction promises are invalid; must clearly mark all US-China route targeted charges,billing standards,and responsible parties.For customer-designated forwarders,send fee details to customers for confirmation to avoid subsequent fee evasion.

Second,submit AMS/ISF declarations 72 hours in advance,ensuring full consistency with customs declaration forms and manifests—especially HS code,cargo value,and product name.Even minor brand declaration differences may trigger targeted inspection and additional surcharges.Zhongshitong’s declaration team covers 8 ports nationwide (Shanghai,Shenzhen,Ningbo,etc.),comparing declaration elements of three document types in advance with error rate ≤0.1%.

Third,enterprises shipping under EXW terms must separately agree on US route ocean freight surcharge responsible party in trade contracts.Default EXW terms require shippers to bear logistics fees; without clear agreement,all China route targeted charges fall on export enterprises.

2026 US Route Charge Trend Forecast

In 2026,US route ocean shipping targeted charges will maintain a stable and slightly decreasing trend.A temporary 10%-15% port congestion surcharge may be imposed during June-August peak season.Enterprises with monthly shipments over 50 containers should lock in booking space and fees 2 months in advance to avoid temporary price hikes.We have 12 cooperative agents on US East/West Coasts,querying port congestion status and predicting inspection probability in advance to help enterprises plan shipping time and reduce unnecessary surcharge expenses.
