We encourage you to work with your Customs Brokers to monitor customs entries that are in the scope of the Supreme Court case. It’s important to monitor custom entries for liquidation status, as it could impact the method of obtaining refunds if they are offered. Below, we define the liquidation process and provide the regulatory reference if you wish to perform more research on the topic.
Liquidation Date (Simplified with CFR context and Current Guidance)
- What is Liquidation: The date when CBP finalizes the duties, taxes, and fees on an import entry.
- When it normally occurs: Within 1 year from the date of entry (19 U.S.C. § 1504).
- How liquidation can be extended: CBP can extend the liquidation period up to 3 years if more time is needed to review the entry (19 CFR § 159.1). In special cases, liquidation may be suspended longer, such as pending court decisions or administrative reviews.
- Current guidance: CBP has not issued specific instructions regarding extending liquidation periods or filing placeholder protests for entries affected by tariffs currently under review by the Supreme Court. Importers should monitor developments and consult legal counsel to determine the best approach.
- Effect of liquidation: Once liquidation occurs, the duty amount is final. Importers then have 180 days from the liquidation date to file a protest if they disagree.
U.S. Port Fees on Non-U.S. Vessels (Effective October 14, 2025)
The U.S. is introducing new port fees targeting foreign vessels, especially those built in China, to encourage use of U.S.-built ships.
Key Points:
- Chinese-owned/operated vessels: $50 per net ton per U.S. voyage (increasing annually).
- Non-Chinese operators of Chinese-built ships: $18 per net ton or $120 per container, whichever is higher.
Exemptions:
- U.S.-owned vessels
- LNG and car carriers supporting U.S. military operations
- Vessel owners ordering U.S.-built ships may waive fees
Carrier Actions:
- Shipping lines are actively rerouting Chinese-built vessels away from U.S. ports to avoid the fees.
- Examples include rerouting via Mexico or adjusting fleet deployments to minimize exposure.
Important for Shippers:
- Currently, major shipping lines do not plan to pass these fees on to importers/exporters. However, shippers should check with their specific carriers to confirm how fees are handled under their contracts. Be aware that rerouting may affect transit times and port calls.
Impact:
- Fees could increase operational costs for shipping lines, but for now, the intention is to absorb them.
