The Court’s ruling recast the outlook and raised questions around cost structures, refund mechanisms, and applicable exemptions.
Recent legal and policy shifts have reshaped the US tariff framework and are forcing importers to reassess their landed cost. This shift raises a wide range of questions: how tariff lines should be entered in the HTS, which exceptions can be supported, and when the refund of duties already paid may take effect, or be pushed back.
After the ruling, US Customs and Border Protection stated that it would stop collecting IEEPA tariffs and deactivate the tariff codes associated with those orders. Against this backdrop, importers now face a different cost structure.
At Aerodoc, a company focused on international logistics and IOR and EOR services, we are closely monitoring this situation. In this article, we review what changed after the ruling, which measures remain in force, and what importers should keep in mind to operate with greater predictability.
Where Tariffs Stand After the Court’s Ruling
The White House issued a proclamation imposing a temporary surcharge under Section 122 of the Trade Act of 1974. The official text set the measure at a 10% ad valorem surcharge for 150 days, effective February 24, along with a broad set of exemptions tied to economic and strategic considerations.
The ruling does not remove tariffs imposed under other legal authorities. In particular, CBP stated that the suspension of IEEPA collections does not affect tariffs imposed under Section 232 (national security) and Section 301 (unfair trade practices), which remain in effect where applicable.
What Changes for Importers
The Supreme Court’s decision has changed the outlook for companies importing goods into the US. The ruling has forced businesses to reassess their pricing strategies, supply chain calculations, and customs compliance and duty planning.
For many importers, the immediate consequence is financial relief. However, a temporary 10% surcharge adopted under a different legal provision remains in place for a limited period, and other trade measures linked to national security or unfair trade practices continue to apply where relevant. In practice, this means that not every importer will benefit in the same way, and assumptions of across-the-board relief could prove costly.
The decision also places renewed importance on classification and documentation. Companies should carefully review each product’s tariff treatment, confirm whether any additional provisions still apply, and guarantee they can support any claimed exception or preferential treatment before customs authorities.
Another area to watch closely is reimbursement. US authorities have indicated that they are preparing a mechanism to return duties collected without legal basis, although uncertainty remains over how quickly that process will move. Until further guidance is issued, importers should closely follow official updates and maintain complete records to avoid compliance risks or missed refunds.
Where to Check a Specific Tariff and Which Official Sources to Review
To determine the status of a specific tariff, the first step is to identify the relevant HTS subheading at the 8- to 10-digit level and then verify whether it carries additional layers under Chapter 99 tied to Section 122, Section 301, Section 232, or other trade measures. CBP published CSMS guidance on the application of the Section 122 surcharge and related exemptions, while USTR maintains an official tool to check whether a subheading is subject to Section 301 and at what rate.
In parallel, the US International Trade Commission (USITC) announced its Harmonized Tariff Schedule search tool and presented it as the main entry point for reviewing chapters 1 through 99.

Q&A
- How should importers assess landed cost after recent US tariff changes? Importers should reassess landed cost by reviewing HTS classification, Chapter 99 tariff exposure, and any applicable Section 122, Section 232, or Section 301 duties. A precise US tariffs for importers strategy helps prevent margin erosion and improves import cost planning.
- What documentation is required to support tariff exemptions in the United States? To support tariff exemptions, importers typically need product classification data, commercial invoices, origin documentation, and technical specifications aligned with US Customs requirements. Strong import compliance documentation reduces risk when managing US tariffs for importers and customs audits.
- How can companies determine whether a product is still subject to additional US tariffs? Companies should verify the HTS subheading at the 8- to 10-digit level and review any related Chapter 99 provisions linked to Section 122, Section 232, or Section 301 measures. This process is essential for accurate US tariff classification and import duty calculation.
- What should businesses do to prepare for potential US tariff refunds or delayed reimbursements? Businesses should maintain a clear audit trail of entries, duty payments, broker filings, and product-level tariff treatment to support any future refund process. A proactive customs compliance approach strengthens recovery readiness and reduces disruption for importers operating in the US market.
