       iii)   Contract weight of bale                                  1050 lbs (476 kg)
       iv)    Moisture regain                                  Not less than contract weight
        v)    Moisture regain                                          22 percent, Max
       vi)    Oil content on dry deoiled material basis                 8 percent, Max


Note 1- the number of bags per bale shall be 400 or as specified in an agreement between the buyer and
the seller.


Note 2- Contract weight of a bale is calculated as follows:
Contract weight of a bale = Nominal weight of a bag x Specified number of bags per bale.
(Contract weight of a bale specified in the table is on the basis of 2.625 lb. (1190g) per bag and 400 bags
per bale.)
Note 3- Corrected net weight of a bale is calculated as follows:


Corrected net weight of a bale    =   net weight x (100+contract regain percent)
                                      100 + average moisture regain percent


Note 4- the specified oil content value of 8 percent corresponds to about 7 percent when determined on
dry deoiled material plus 20 percent regain basis.
