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.
Service and general suppliers: SSIG members who are working for a corporation or subunit of a corporation whose major activity is providing for producers of pulp and paper a service or any other commodity not included in the other supplier categories.
Commercial users of pulp or paper: SSIG members who are working for a corporation or subunit of a corporation whose major activity is the use of paper, pulp, corrugated, packaging material, or other related product after it has been produced and further converted into some finished sheet or roll form or intermediate finished article of commerce. This includes printers or, in general, any entity using paper where that use does not generally fit under the term "converter."
Marketers and Commercial Sellers: SSIG members who are working for a corporation or subunit of a corporation whose major activity is the marketing or sales of pulp or paper. This might include but is not limited to companies whose focus is the wholesale or retail selling of paper and paper products including cut size paper, paper tissue products, artist paper supplies, paper merchants, recyclers, etc.
Consultants: SSIG members who are independent contractors and who may provide consulting services to any segment of the industry.
Educators: SSIG members who teach or are employed by an academic institution.
General Interest: SSIG members who are not covered under any of the above categories; this category may include, but is not limited to, members affiliated with trade associations, professional societies, or government agencies, and retirees.
