About Jason P. Wapiennik

Jason Wapiennik is a customs attorney and the founder of Great Lakes Customs Law. For more than 15 years, he has focused exclusively on U.S. Customs & Border Protection matters, helping individuals and importers nationwide resolve seizures, penalties, prior disclosures, RFIs, protests, classification disputes, AD/CVD issues, offers in compromise, drawback questions, and more—including matters that reach federal court and the Court of International Trade. He has handled 700+ cases, has more than 100 active matters at any given time, and has recovered over $11 million for clients. Jason knows the FP&F process at ports around the country and has built strong working relationships with the officers and teams who decide these cases. Based in Illinois and Michigan, he serves clients from offices in Chicago and Detroit and works remotely nationwide. Before founding the firm in 2009, he trained at Edmund Maciorowski, P.C. His results are visible in published outcomes and rulings, but many wins happen quietly through practical advice that prevents larger problems.

I highly recommend Jason for anyone seeking reliable legal representation. Throughout my case, he demonstrated extensive knowledge and provided clear, practical guidance every step of the way. His instructions were always easy to understand and he is very organized, which made the process much less stressful. He consistently answered all of my questions promptly and thoroughly, ensuring I was informed and confident throughout the case. I am very grateful for his support and would not hesitate to work with him again or recommend him to others.

I cannot recommend my customs attorney enough. We were facing a customs issue involving a bill of nearly $200,000, and he was able to step in, navigate the situation professionally, and negotiate it down to approximately $20,000. Throughout the entire process, he was knowledgeable, responsive, strategic, and extremely experienced with import and customs matters. If you are dealing with import/export issues, customs disputes, duties, or international trade concerns, I highly recommend reaching out to him. His expertise saved our company a substantial amount of money and stress.

We needed fast, reliable guidance on a complex HS classification issue with real financial impact. We’ve used this firm multiple times and keep coming back for a reason. They provided clear, well-supported guidance on a complex HS classification with real financial impact, plus practical help to correct prior entries. Responsive, professional, and reliable under deadline pressure.

Excellent service navigating the tariff challenges cross border importing from Canada to the USA. We are a manufacturer of different and unique products and Jason was an authority on rulings-based classifications, which we found very helpful in our CBP dealings.
