NR 284.03(2)(2) “BCT bleached kraft subcategory” includes those mills at which bleached kraft pulp is produced in a full cook process employing a highly alkaline sodium hydroxide and sodium sulfide cooking liquor. NR 284.03 NoteNote: Principal products include paperboard (B), coarse papers (C), tissue papers (T) and market pulp.
NR 284.03(3)(3) “Bisulfite cooking liquor” means sulfite cooking liquor having a pH between 3.0 and 6.0. NR 284.03(4)(4) “Builders’ paper and roofing felt subcategory” includes those mills at which heavy papers used in the construction industry are produced from wastepaper, wood flour and sawdust, wood chips, and rags. Neither bleaching nor chemical pulping processes are employed on-site. NR 284.03 NoteNote: Principal products include saturating, deadening, and flooring papers, and roofing felt.
NR 284.03(5)(5) “Corrugating medium furnish subdivision” includes those mills in the paperboard from wastepaper subcategory where only recycled corrugating medium is used in the production of paperboard. NR 284.03(6)(6) “Cotton fiber furnish subdivision” includes those mills in the nonintegrated-fine papers subcategory which produce a paper product containing equal to or greater than 4% cotton fibers. NR 284.03(7)(7) “Deink subcategory” includes those mills at which brightened or bleached deinked pulp is produced from wastepapers using an alkaline process to remove contaminants such as ink and coating pigments.

NR 284.03(8)(8) “Dissolving kraft subcategory” includes those mills at which a highly bleached pulp is produced by a full cook process employing a highly alkaline sodium hydroxide and sodium sulfide cooking liquor. Included in the manufacturing process is a precook operation termed prehydrolysis. NR 284.03 NoteNote: The principal product at these mills is a highly bleached and purified dissolving pulp used principally for manufacture of rayon and other products requiring the virtual absence of lignin and a very high alpha cellulose content.
NR 284.03(9)(9) “Dissolving sulfite pulp subcategory” includes those mills at which a highly bleached pulp is produced in a full cook process employing strong solutions of sulfites of calcium, magnesium, ammonia or sodium. NR 284.03 NoteNote: Principal products include viscose, nitration, cellophane or acetate grade pulps which are used principally for the manufacture of rayon and other products that require the virtual absence of lignin.
NR 284.03(10)(10) “Fine bleached kraft subcategory” includes those mills at which bleached kraft pulp is produced in a full cook process employing a highly alkaline sodium hydroxide and sodium sulfide cooking liquor. NR 284.03 NoteNote: Principal products are fine papers, which includes business, writing and printing papers, and market pulp.
NR 284.03(11)(11) “Full cook” means chemical pulping methods which employ the heating under pressure of wood, water and chemicals in a closed vessel to a temperature sufficient to separate the fibrous portion of the wood by dissolving lignin and other nonfibrous constituents. NR 284.03(13)(13) “Groundwood-chemi-mechanical subcategory” includes those mills at which pulp is produced, with or without brightening, utilizing a chemical cooking liquor to partially cook the wood followed by mechanical defribration by refining, resulting in yields of 90% or greater. NR 284.03 NoteNote: Principal products include fine papers, newsprint, molded fiber products and market pulp.
NR 284.03(14)(14) “Groundwood-CMN papers subcategory” includes those mills at which groundwood pulp is produced, with or without brightening, utilizing only mechanical defribration by either stone grinders or refiners. NR 284.03 NoteNote: Principal products include coarse papers (C), molded fiber products (M), newsprint (N) and market pulp.
NR 284.03(15)(15) “Groundwood-fine papers subcategory” includes those mills at which groundwood pulp is produced, with or without brightening, utilizing only mechanical defribration by either stone grinders or refiners. NR 284.03 NoteNote: Principal products are fine papers, which includes business, writing and printing papers, and market pulp.
NR 284.03(16)(16) “Groundwood-thermo-mechanical subcategory” includes those mills at which pulp is produced in a brief cook process employing steam, with or without the addition of cooking chemicals, such as sodium sulfite, followed by mechanical defribration by refiners, which are frequently under pressure, resulting in yields of approximately 95% or greater. The pulp may be brightened using hydrosulfite or peroxide bleaching chemicals. Principal products include market pulp, fine papers, newsprint and tissue papers.
