★★★★★

“We hired Anatolii Trembach and Trembach Law Firm for a customs/tariff refund matter. Anatolii was professional, responsive, and clearly explained the process. He helped us recover our refund, and we are very satisfied with his work. We would recommend Trembach Law Firm to other importers and businesses dealing with customs matters.”

★★★★★

“Our duty drawback claims were being rejected by CBP without explanation. Mr. Trembach analyzed the rejections, identified the procedural deficiencies, and resubmitted the claims correctly. We recovered substantial overpaid duties we had written off as lost. If your duty drawback claims are stuck, Trembach Law Firm can unblock them.”

FAQ

Customs and trade questions.

What does a customs attorney do?+

Represents importers before U.S. Customs and Border Protection and, when needed, the U.S. Court of International Trade. Classification and valuation disputes, protests, seizures, penalties, compliance, duty refunds. The goal: resolve the matter correctly and on time. We represent businesses only — importers, exporters and their companies. No private individuals.

CBP detained or seized my shipment. What now?+

Act fast: the notice sets the clock. We review it and find the basis for the hold. Then we seek release by petition for remission or mitigation, or another fit response.

I got a § 1592 penalty notice. Can you help?+

Yes. Exposure turns on the alleged culpability: negligence, gross negligence or fraud. We answer the pre-penalty and penalty notices. Where fit, we advise on prior disclosure to cut exposure.

How do protests and classification disputes work?+

A protest under 19 U.S.C. § 1514 challenges CBP's classification, valuation or liquidation decision. It is generally due within 180 days of liquidation. We prepare it with the tariff and legal basis. If denied, we weigh a challenge at the Court of International Trade.

Do you handle duty and tariff refunds, including IEEPA?+

Yes. Through CBP's refund channels and, where required, litigation at the Court of International Trade. The path depends on your entries and their liquidation status. We review it with you.

I also paid the Section 122 surcharge — can I recover it?+

In 2026 the government imposed a separate 10% import surcharge under Section 122 of the Trade Act of 1974 (19 U.S.C. §2132), in effect February 24 to July 24, 2026. The U.S. Court of International Trade struck that surcharge down; the appeal is pending. Section 122 has no automatic CAPE refund, so an importer who paid it must preserve the claim by protest or a Court of International Trade complaint. If you paid both IEEPA and Section 122 duties, we plead both to reserve your rights to each refund — on the same fee: 2% for a CAPE filing only; 7% for CIT litigation, or a flat $2,000 if your refund is under $29,000.

Do you work with importers outside California?+

Yes. We are in Calabasas and serve importers nationwide, including the Ports of Los Angeles and Long Beach. The Court of International Trade is a national court based in New York. It covers customs matters across the country.
