Paracord (or paraline as it is often sold) comes in different breaking strengths. True 55O cord also comes in different types. Mil-spec comes in 6 varieties, ranging from 95 lbs breaking strength to 750 lbs breaking strength. The more easily found civillian versions of this come in a couple types as well. 550 cord can only be deemed "mil-spec" if it is quality control checked every 20 feet I believe, whereas the civilian stuff is checked every 100 feet or so. Same stuff, different certification process.
550 cord is by far the most popular, and has an outer sheath with a breaking strength alone of 330 lbs. Each inner strand being around 33lb breaking strength. The other commonly available paraline is 650 cord, which actually has a breaking strength of around 450 lbs. It is made up of 4 strands, usually fuzzier and more yarn-like than the 550 strands.
Either of these types is usually more than enough for camping purposes, and I wouldn't be too worried about getting "bad paracord". Unless you're lifting vital equipment or people with it, just the gutted sheath alone is going to be able to handle most stuff.
Hope you get a good batch in your order, and have fun playing with it. It's like duct tape for me, I use it for everything.
