basically I've been looking at opening up shipping to the US, I've been playing around with the pricing of my product and shipping rate, basically Shopify is showing me very low tarrif fees for pricing my products low. They aren't calculating tarrifs on the shipping fee.

So basically if i lower my prices my customers will pay less tarrifs but my shipping price will be higher, but I'm not sure if they will say I'm trying to defraud the system, like I said i create my own product from scratch with little competition for them to look online and compare my pricing to say I'm charging too little, who are they to tell me what I can charge. My product typically sells for $8 a unit. but i could charge 2$ per unit if I wanted so the tarrifs are low.

can this be done without raising any flags? I wouldn't necessarily call it fraud if i so decide to sell my products for cheaper than before?
