Use a Customs Administration's Own Techniques to Lower Your Duty Rates
Customs administrations use 'tariff engineering' techniques to look beyond a product itself, examining packaging, marketing, instruction guides, and bundle composition, to assign the highest defensible duty rate. Our Tariff Classification Engineering Program applies the exact same techniques in reverse: identifying product, packaging, or marketing modifications that legitimately qualify your goods for lower rates.
What CBSA Actually Looks At
Most importers assume the H.S. classification of a product is determined by what the product is. CBSA assesses much more than that. When determining classification and duty rates, they take into consideration:
1. Marketing material (websites, advertising, retail signage).
2. Owner's manuals and product instruction guides.
3. How the product is packaged for retail sale.
4. Other items included in the retail package or bundle.
5. Branding language and product naming.
Their primary mandate is to protect government revenue, so they apply these factors to support the highest defensible duty rate. Our program applies them in the opposite direction, identifying changes that legitimately support the lowest defensible duty rate, and protecting the result with a binding ruling.
How the Program Works
You select the products or product lines you want us to review. Our Rulings Department deconstructs each one, the product itself, the packaging, the retail presentation, the marketing collateral, the included accessories, and identifies modifications that could legitimately move the product into a lower duty category.
For products where we identify viable opportunities, we recommend specific changes (which can range from minor packaging adjustments to retail bundle composition changes), file the binding ruling once the changes are implemented, and document the projected duty savings against current import volumes.
Why Our Rulings Team Runs This Program
Tariff engineering is not classification work; it is adversarial classification work. The team must anticipate exactly how a Customs officer will approach the product, then build a position that pre-empts the most aggressive classification Customs officer would otherwise reach. Our Rulings team does this every day in appeal proceedings, which is why they run this program for our clients.
Frequently Asked Questions
Yes, when done properly. Tariff engineering uses the same legitimate classification rules CBSA itself applies. The line between legal tariff engineering and aggressive non-compliance is precisely where our team's expertise matters most. Every recommendation we make is grounded in current legislation and protected with a binding ruling.
Savings vary dramatically by product category. Some products have no meaningful tariff engineering opportunity. Others can move from a duty rate of 6–18% to duty-free with packaging or marketing adjustments. We quantify the opportunity per product line during the initial review.
Sometimes. Most tariff engineering changes are operationally minor, adjustments to packaging, instruction guides, or accessory inclusion. Where larger marketing changes are required, we present them as options for your team to evaluate. You always decide whether to implement the recommendation.
