    As far as I know you can use the 43 or unmarked chain. You will have to work within the limits or about one size larger than a grade 70. Look at the DOT site for your state or the federal motor carrier regs.

    Grade 43 or 70 can be used for securing equipment as long as it exceeds the WLL (working load limit) as shown in the link to the Federal Motor Carrier Securement rules I posted in the thread below.

    grade refers to the hard/tough-ness of the chain.
    much like bolts where a grade 8 is tougher and harder to break than a grade 3.

    3/8 grade 43 chain is rated at 5400# and grade 70 is 6600# not a huge difference but not a huge difference in price.
    Plus the grade 70 chain has that beautiful goldish chromate finish, not only looks good but is highly corrosion resistant.

    I would get the G70.

    And the best thing about grade 70 is, you can generally go down one size in your chain. That makes it lighter! Hefting chains around gets old..

    And it's more resistant to rust!

    You mean like this nice golden finish?

    I needed a short piece of logging chain so I bought the unplated grade 43 and plated it at work. This is better then any plating you will get of the shelf. It is a zinc-nickel alloy (87/13) with chromate topcoat finish. We use it on aircraft bearings.

    The working load limit of Grade 43, 3/8" chain is 5400 lbs. The working load limit of Grade 70, 5/16" chain is 4700 lbs.

    Your original question asked if you could use grade 43 for hauling. The answer was yes but I also agree that for the minimal difference in price get the grade 70 chain. Mike posted the specs for each.
