Producers of pulp or paper: SSIG members working for a corporation or subunit of a corporation whose major activity is the production of pulp or paper.
Converters of pulp or paper: SSIG members working for a corporation or subunit of a corporation whose major activity is the conversion of pulp or paper into some finished or intermediate manufactured state. Converters would include, but is not limited to, producers of corrugated roll goods, manufacturers of boxes, converters who buy rolls of tissue paper and convert it into finished saleable consumer goods, converters who use paper or similar materials to produce packaging of various kinds (including flexible packaging) and numerous similar producers of paper goods.
Suppliers of chemical or raw materials: SSIG members who are working for a corporation or subunit of a corporation whose major activity is to supply raw materials or chemicals for the manufacture of pulp or paper.
Suppliers of manufacturing equipment, instrumentation and online controls: SSIG members who are working for a corporation or subunit of a corporation whose major activity is to supply manufacturing equipment, instrumentation, or online controls for the manufacture of pulp or paper.
