Our Expertise

Imports and exports are the lifeblood of the global economy, but the regulation of international trade is continually evolving, and often subject to political machinations. In a world in which “trade wars” and “tariffs” have become everyday language, compliance with U.S. Customs law requires far more than ensuring forms are correctly prepared and prohibited goods are not landed at a U.S. port.

Just as conditions such as labor costs must be considered when choosing a manufacturing location, companies must carefully consider the tariff and duty implications of importing goods manufactured in those locations. Experienced at operating in all the major manufacturing centers in Asia, Europe and Latin America, our lawyers are uniquely equipped to provide importers, manufacturers and exporters with legal assistance on a full range of international trade and customs matters.

We help identify duty mitigation strategies that may save our clients money; we help companies develop and implement internal import controls; and we help our clients respond when regulatory or enforcement issues arise, e.g., when duties are improperly assessed, errors are discovered and need to be disclosed, penalties are issued, or goods are seized. Our cannabis clients in particular benefit from our experience dealing with the issues that affect their industry, such as import/export restrictions on CBD products and items that may be considered drug paraphernalia.

Ensure Ongoing Compliance

At the same time, the U.S. government’s actions to combat terrorism and human rights abuses around the world are leading to greater burdens on companies to ensure that their supply chains are secure and do not involve the use of forced labor. Facing the risk of significant fines, plus the indefinite exclusion of their products from the U.S. market, businesses simply cannot afford to ignore the issue (or rely only on the assurances of their suppliers) and must diligently monitor their entire supply chains, all the way down to the raw material used.

Every day, we help clients in dozens of industries determine how best to structure their international trade operations and to navigate the customs and import landscape to their best advantage. Knowledgeable, connected, and client-focused, our lawyers can help you optimize your cross-border supply chain operations, while ensuring your ongoing compliance with ever-changing laws and regulations.

This law firm was a huge help as our company went through the process of commercial licensing in the California cannabis industry.  They have helped us with a variety of legal issues in a timely fashion, while clearly communicating with us throughout the process.  Everyone we’ve worked with at Harris Sliwoski is an expert in their field and we have always felt that we were in good hands through our legal representation.

user icon Wil Crummer, CEO PRO Farms

Legal stuff is always scary. And I’ve had to play offense a couple times, begrudgingly. To have Harris Sliwoski have my back? It made things a lot less prickly. They quickly walked me through my options, and were refreshingly consistent in their communications, timing and billing. I’ve been lucky to stay out of the legal side of things my whole career, thankfully. When things went a little wrong, Harris Sliwoski quickly made things right.

user icon Aaron Draplin, Founder Draplin Design Co.

I am impressed with this law firm. They answered all my questions regarding cannabis businesses and the California cannabis framework, and they have helped me with a variety of legal issues in a timely fashion, while always clearly communicating with us throughout the process. They also redirected me to other quality people for my business needs. Everyone I worked with at Harris Sliwoski is an expert in their field, and I was in good hands throughout my legal representation.

user icon Corey T., CEO Thinc Cubed, LLC

I have been working with the lawyers at Harris Sliwoski for more than 20 years both as a business owner and as an executive at a large east-coast health system and that is because they have always efficiently provided high level and clear international law advice. Most recently, Harris Sliwoski provided legal support on many matters related to procuring medical products worldwide. Their support was particularly helpful to during the onset of COVID, when there was a big need for securing PPE quickly, all while navigating complicated international and domestic legal requirements. Harris Sliwoski’s team of international lawyers helped by conducting rapid-fire due diligence on potential suppliers, navigating the legal logistics for getting product from overseas and through U.S. customs, and drafting contracts to protect against various sorts of horribles. They did this by essentially providing what amounted to 24/7 service. I cannot recommend them highly enough.

user icon Matt Hurt, COO Cannabis Nation

You won’t find a better partner than Harris Sliwoski when trying to navigate the complex world of healthcare regulations.  They not only give sound and reliable legal advice, but they are also very responsive and are able to guide you in a way that helps you reach your business objectives as well.

user icon Joseph Axelrod, General Counsel Irwin Naturals

When we started the process of building a ‘seed to sale’ cannabis company in Oregon, we saw the need for expert legal counsel.  The cannabis sector is fraught with potential peril at every turn, and we wanted the best legal advice we could find.  After talking to several firms and individuals, we feel extremely fortunate to have chosen Harris Sliwoski as our legal counsel.

user icon Tony Theiss, CEO and Co-Founder Redbarn Cannabis 

We use Harris Sliwoski on all our international legal matters, including on our international litigation matters. We have over the last few years been involved in a couple big international legal disputes and Harris Sliwoski’s international dispute resolution team provided us with expert legal assistance on both matters. They were always very careful to explain to us what they were doing and why and what their actions would likely cost us in legal fees. Most importantly, we did extremely well on both cases and I have no doubt Harris Sliwoski was a big factor in that.

user icon Kevin English, CEO We Are Camp

We have used Harris Sliwoski for legal help related to our international manufacturing. The lawyers with whom I worked had extensive familiarity with the international legal issues involved in our various projects and offered us key insights. I particularly appreciated how they always quickly and efficiently do what they say they will do and always within their cost estimates.
