Product weight 49.9g, shipping weight 454g.

I'm confused as to the difference between item weight and shipping weight. Initially, I thought item weight is simply the item in its original packaging, and shipping weight is the combined weight of the item and the box with the bubble wraps/filling paper .etc. I googled this, and apparently shipping weight is the item and its packaging. So in this context, the ryzen processor itself is 49.9g, but with its packaging, it is 454g? Please can you clarify this for me, thank you so much!
The Item weight Is almost on par with AirPods- which have a high success rate with the "missing Item" method, so use that.

The Item weight Is exactly that- the weight of the Item, "net" weight.

The shipping (gross) weight, Is everything contained In (and Inclusive of) the package.
