Did you read the msds that came with it. That will explain a lot. If hazmat I believe anything over 1100 lbs has to have placards. If its on a public street, you have to be in compliance so distance has no bearing at all.

Yeah. I'm pretty sure this requires placarding then.
I have read the MSDS, that's how I know what's in it (when I saw nitric acid I had to read it to see why we use it, what it's used for. I mean the stuff literally dissolves even silver)

This isn't the exact product but it's an older version of it: http://www.kelleysupply.com/customer..._AC-55-5CL.pdf

I think it might be 1,001 pounds actually, but regardless, if I have one barrel of this, and say another barrel with Quorum Green, which contains sodium hypochlorite (msds here: http://www.kellysolutions.com/erenew...2_05_05_PM.pdf). Now each one is below 1001lbs but combined they're over. Does this require placarding?

Those would both be Class 5, so if I understand correctly, that would be a yes, right?

This (http://www.kelleysupply.com/customer...ORUM_BROWN.pdf), another product I haul, is class 8. If I have 600lbs from Class 5 and 600 from Class 8, does this require placarding?

These rules and laws are complicated to a newcomer, and now that I've realized this is a legal issue, I want to make sure I have it right. I have moved these things hundreds of times and it never occurred to me until a few hours ago, and I want to make sure it gets done correctly. I don't want anyone getting in trouble over cleaning chemicals.

Wasn't the exact site i was looking for but it helps you out with the weight and placard requirements.

Most shippers of hazmat are familiar with the placard requirements. But, you need to get a copy of the handbook for yourself so that you can make sure that you are in compliance. All it takes is one mistake and you will have some serious consequences. If you don't want to get a handbook then check the fmcsa website and print off what you need.

All of your questions will be answered in the CDL Manual under the Hazmat Endorsement section, you can get a copy from your local BMV or online, just google hazmat endorsement.

If that column is marked with and "X", then you will need a placard. Having a reportable quantity means you also need to have the endorsement for HazMat, proof of insurance for transporting hazmat and all the required paperwork and MSDS' to go with it.

The Bill Of Lading or Shipping Paper being marked Hazmat by itself does not mean placards are required. A Table 1 hazmat requires placards, no matter the weight ot amount. A Table 2 hazmat does not need placards until 1001 pounds gross weight.
Each hazmat is assigned a UN number, or a UA number (less common). These can be looked up pretty easily to see if they are Table 1 or Table 2 and what placards, if any, are needed.
