Global Trade and Customs


Miller Thomson’s Global Trade and Customs Group offers a full range of global trade, customs and import tax services. Members of the group have a range of strengths and experiences ranging from leading legal counsel to consulting experts. We have the experience, skills and perspective required to provide high quality, practical and innovative solutions. We also have the bench strength necessary to assume conduct of significant, time-sensitive and complex customs appeals and trade remedies matters.

We serve domestic, non-resident and global businesses (especially US-based multinationals importing into Canada).  We have represented  importers and exporters in most Canadian industry sectors including: aerospace, aluminum and steel, automotive, agriculture / agri-food, apparel, banking and financial, communications, defence production, direct sales, e-commerce, fisheries, forestry, manufacturing, oil and gas, technology, third party logistics, transportation, and mining.  We have also assisted trade-related service providers, including accounting firms, carriers (in all modes of transportation), certifiers, couriers, distributors, freight-forwarders, insurers, shippers, steamship lines, suppliers, and third party logistics providers.

In this era of rapid change in global trade and customs, support from the right group can make all the difference. Managers of global businesses today must cope with factors such as increased tariffs, new free trade agreements and changing supply chains in an effort to minimize risk and maximize opportunities.  In dealing with the issues, we have come to understand typical global trade business strategies, business trends and best practices.

We put our knowledge of global trade businesses (such as accounting systems, customs controls and procurement processes), as well as our knowledge of applicable laws and policies, to work for our clients. Our understanding of the business of global trade and customs extends well beyond customs duties and import taxes, to matters such as consumer product safety, e-commerce, as well as import and export controls.  Some members of our group are former Canada Border Services Agency and Department of Justice, Canada employees.  As such, they have a have a good understanding of the machinery of government.
