Got to put my 2 cents in...as far as being here in the states! Personally I don't care or trust what Lb the stock is labeled. The stuff I have purchased recently has just started to include g/m2 so that helps some-what. But, you can get 110lb card stock that is actually thinner than 80lb. I go by the thickness, which unfortunately means I have to physically see the stock at some point! I have a general guide I found awhile back, 80g/m2 = copy paper ( usually) 180-200g/m2=tag board.
the models want you to glue up different parts to usually .2mm, .5mm and 1.0mm for the various parts....Standard Card stock =110lbs,199m/2 = .023mm, or cover stock @ 67lbs or 148m/2 =0.21mm ( both from Staples). I have some Eagle brand Tag Board from Michales that comes in a 9x12 ( lbs or g/m2 not listed) but it is .25mm ( warning it is a layered stock, if you try to roll it, the layers separate!)
Poster Board from Walmart in 18x24 sheets, Phantom Line or plain ( has one slightly glossy side sometimes) is exactly .5mm thick and sometimes for the smaller stuff I will just glue a couple together for the 1.0mm, Tetley Tea Boxes are made of exactly .5mm card stock with glossy print outside, but pure matte white inside, so glue the model page to the outside , a little spray sealer, and I air brush everything anyway. For the large 1.0mm frames etc. I use a good flat white mat board, like Zathros, the kind used for framing. I tried cereal box stock 1 time, and it will destroy a new blade in a matter of a few cuts so I do not recommend using it, but I will re-cycle anything else suitable for what I need or will work! Tubes that need to be glued together with tabs in a kit I usually will throw out, and roll them to the proper length and thickness using wire or dowel rod, knitting needles, what-ever and copy paper, works WAY BETTER! GLUE...Aleene's Tacky Glue, Fast Dry, Fast Grab Regular..what-ever one will serve the purpose at the time, 3M spay adhesive for joining 2 pieces of board together, with a brayer. and VERY CAREFULLY as it will grab and not let go if you get things miss-aligned! I will even use Elmers and spread it with old plastic cards that come in the mail, to join flat pieces but they are weighted down till dry and flat! I am sure I have forgotten other things but if there are questions just ask! That's my 2cents worth...
