Filed Court of International Trade Actions

Trembach Law Firm is not only admitted to the U.S. Court of International Trade — it files its own IEEPA refund complaints there under 28 U.S.C. § 1581(i), with new complaints filed as importers sign. CBP deployed CAPE Phase 3 — which covers finally liquidated entries for plaintiffs holding a court reliquidation order — on October 6, 2026. As of October 28, 2026 the firm is counsel in 35 actions at the Court of International Trade, docket numbers 1:26-cv-04095, 1:26-cv-04154, 1:26-cv-04156, 1:26-cv-04164, 1:26-cv-04185, 1:26-cv-04248, 1:26-cv-04271, 1:26-cv-04277, 1:26-cv-04300, 1:26-cv-04327, 1:26-cv-04328, 1:26-cv-04335, 1:26-cv-04342, 26-04390, 26-04392, 26-04393, 26-04394, 26-04395, 26-04396, 26-04418, 26-04421, 26-04488, 26-04556, 26-04559, 26-04563, 26-04568, 26-04569, 26-04616, 26-04617, 26-04618, 26-04643, 26-04668, 26-04745, 26-04766, 26-04797 (list and verification: Court of International Trade filings). 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 does a tariff lawyer in Calabasas do?
A tariff lawyer in Calabasas specializes in Harmonized Tariff Schedule (HTS) classification, helping importers correctly classify products to determine duty rates. Services include binding ruling requests, classification dispute defense, tariff engineering for duty minimization, CF-28/CF-29 response preparation, and Court of International Trade litigation. Our Calabasas office at 27001 Agoura Road serves businesses throughout California.
Why is proper tariff classification important?
Proper tariff classification is critical because the 10-digit HTS code determines your duty rate (0% to 100%+), eligibility for free trade agreements like USMCA, Section 301 tariff exposure, antidumping/countervailing duty liability, and compliance with import regulations. Classification errors can result in CBP penalties of 2-4x the loss of revenue under 19 USC 1592.
How much does a tariff lawyer in Calabasas cost?
Trembach Law offers transparent pricing for tariff classification services. We provide free initial consultations, flat-fee pricing for binding ruling requests and classification analysis, and competitive hourly rates for complex disputes and litigation.

Can you help with tariff classification disputes at Port of LA?
Yes, our Calabasas office provides rapid response to classification disputes at Port of Los Angeles and Port of Long Beach (45-60 minutes away). We handle CF-28 requests for information, CF-29 notices of action, classification protests under 19 USC 1514, and Court of International Trade litigation.
What is tariff engineering?
Tariff engineering is the legal practice of modifying product design, composition, or import configuration to achieve a more favorable HTS classification and lower duty rate. When done properly with guidance from a tariff lawyer, this is completely legal and can result in significant duty savings. Our Calabasas tariff lawyers help businesses identify legitimate tariff engineering opportunities.
How do I get a CBP binding ruling for tariff classification?
A CBP binding ruling under 19 CFR 177 provides official classification guidance that CBP must honor. The process involves submitting detailed product specifications, composition data, technical drawings, and legal analysis to CBP's National Commodity Specialist Division. Our Calabasas tariff lawyers prepare comprehensive binding ruling requests.
What areas do you serve from the Calabasas office?
Our Calabasas headquarters at 27001 Agoura Road, Suite 350 serves the entire San Fernando Valley (Woodland Hills, Tarzana, Encino, Sherman Oaks, Van Nuys), Ventura County (Thousand Oaks, Westlake Village, Simi Valley), West Los Angeles, and all of California.
