Trading not allowed under export-oriented unit scheme

The facility for trading units under the EoU scheme was withdrawn in 2002

We have an EOU manufacturing industrial chemicals and we import our raw materials duty-free. We carry out chemical production and export finished goods duty-free. We have another set of chemicals which we do not make in India but would like to import into our same EOU duty-free and re-export them (as it is, or by repacking). This is trading of chemicals. My questions are: (1) Is this allowed by law? (2) If it is not allowed, what is the penalty if we have done this many times in the past? (3) Can I get a trading licence for doing this
