Filed Court of International Trade Actions

Trembach Law Firm is not only admitted to the U.S. Court of International Trade — it has filed 3 complaints there. The actions are docketed at the Court of International Trade as 26-02506, 26-02846, 26-04095. Anatolii Trembach is admitted to practice before the Court of International Trade and is licensed in California, State Bar #349304, verifiable at apps.calbar.ca.gov.

This matters for IEEPA refunds specifically. The Court of International Trade has ordered CBP to reliquidate and refund on plaintiffs’ entries, and CBP’s CAPE Phase 3 for finally liquidated entries is likewise available only to importers who are plaintiffs at the Court. An importer who never filed has no confirmed, self-executing mechanism. Choosing counsel who has actually filed at that court, rather than counsel who only describes the process, is therefore a practical question and not a marketing one.

Jurisdiction over these actions rests on 28 U.S.C. § 1581, and the window to sue runs under 28 U.S.C. § 2636(i). No particular outcome is promised or guaranteed.

Fees, Costs and Case Results

Representation in these matters is offered on a contingency basis covering attorney fees only: there is no attorney fee unless we recover, and clients remain responsible for case costs, such as court filing and service fees. The specific terms that apply to a matter are set out in the written fee agreement for that matter.

Where this site refers to a verdict, settlement or court order, that result was dependent on the facts of that case, and results will differ if based on different facts. Past results do not predict or guarantee the outcome of any other matter, and no particular outcome is promised or guaranteed.

Frequently Asked Questions

What types of tariffs affect California businesses in 2025?

California businesses face multiple tariff regimes in 2025: Section 301 tariffs on China (25-100%+), Section 232 tariffs on steel/aluminum/copper (25-50%), reciprocal tariffs (10-50%), and new IEEPA emergency tariffs. Our tariff lawyers help navigate all these duty programs and develop mitigation strategies.

How can a tariff lawyer help reduce my import duties?

Our tariff lawyers employ multiple strategies: (1) HTS classification optimization for lower duty rates, (2) tariff exclusion requests, (3) USMCA qualification for Mexico/Canada goods, (4) first sale valuation, (5) supply chain restructuring, (6) tariff engineering, (7) duty drawback claims, and (8) Foreign Trade Zone operations.

What is Section 301 and how does it affect Chinese imports?

Section 301 authorizes the U.S. to impose tariffs in response to unfair trade practices. Since 2018, the U.S. has imposed 7.5-100% additional tariffs on over $370 billion of Chinese imports. These tariffs stack on top of normal duties. Our Section 301 lawyers help with classification analysis, exclusion requests, and supply chain restructuring.

Can I get a refund on tariffs I've already paid?

Yes. On February 20, 2026 the Supreme Court held that IEEPA does not authorize these tariffs, so IEEPA duties are refundable — subject to the deadline that attaches to each entry. We also help with duty drawback (99% refund on exported goods), post-entry amendments for misclassification, and protests for incorrect duty assessments.

How long does it take to get a tariff exclusion?

When exclusion processes are open, USTR typically provides 30-45 days to file requests. Review and decision can take 6-12+ months. We monitor exclusion process announcements and can mobilize applications within 24-48 hours of USTR announcements.
