The manufacturer states this is a milled and air floated Lincoln fire clay. It is an excellent all purpose clay with high strength and plasticity.
An excellent fire clay recommended for industrial as well as for the individual potter. Very good plasticity and green strength.

It is not clear why the chemistry for this is different than for IMCO 800 if they are both airfloating Lincoln Fireclays.

Physical data can be found on the link to the product information web page of the manufacturer.
