But if you follow that link, the "made in America" jeans labels may use imported denim. So, it really is more assembled in the USA, isn't it?

"Made in country A" means at least 51% of the product is made in country A. "Product/Produce of country A" means at least 98% is from country A.

Apart from fresh fruit and veg, it's rare to get 98% stuff. Even at the inception of the industrial revolution, Britain was importing cotton from India and the USA for it's textile mills.

If we went back to a 98% society, we'd be back to wearing wool and linen. Sadly Trump doesn't understand this.
