The math in the article is a bit sketchy. I'm doing this from memory. If a part of a piece say costs $20 and the tariff is added to that part at 100% increases the COGS (cost of goods sold) $20. The article stated the $100 piece of finished equipment would go to $225 because of one part.
Businesses have two decisions to make on their markup. We can either make x% or $x per piece. The said piece of equipment went from $50 to make to retail of $100 to now $70 to make. They still make $50 the price is $120. If they want to make 100% then the $70 piece to make now sells for $140. $225 isn't in the equation. Maybe that part was hyperbole, but come in man. Now let's say 100% of the product and not just a part is made overseas. Now the cost goes from $50 to $100. Now they either sell for $150 or $200 depending on the business model. If it was my business I would do the $150 until it goes back to normal and lower the price to $100 in the future. There are different ways to slice and dice COGS and profit.
