When boxing Amazon, is it best to send them a box with weight equivalent to that of the product which we are returning?

Correct. Boxing Is carrier-based, hence this applies to all companies.

anyone happen to know which carriers in particular are more anal about weight-checking?

All major carriers document both the weight & dimensions at their depot, and charge their rates on volume or weight- whichever Is the greater.

First and foremost, what's the weight of the Item you're planning to SE?

The item in question is about 4lbs. I was unaware that they check dimensions too. I assume there are crucial in successfully boxing Amazon then?
