None of the new Canadian tariffs cover:
Aluminum
Titanium
Quartz
Gemstone
Some wooden products are in the tariffs, but account for less than $10 of the overall cost of the kit and are a different HS code.
In fact, from what I see on the list, none of the products included in the kit use the HS codes listed on the new tariffs.
Additionally, these products are from China. When you fill out the customs form, you fill out the origin country, not the country shipping to you. My products do not qualify as made in the USA, so I don't think any of these new tariffs apply in the first place.
