Products classified under HTS 4705.00.00.00
Chemi-Thermomechanical Pulp (CTMP)
Chemi-thermomechanical pulp (CTMP) is produced by treating wood chips with chemicals like sodium sulfite before mechanical refining under steam pressure, resulting in high-yield pulp with good strength properties. It falls under HTS 4705.00.00.00 as it combines chemical impregnation and mechanical processing to break down wood fibers. This pulp is widely used in newsprint and tissue production.
Thermomechanical Pulp (TMP)
Thermomechanical pulp (TMP) involves steaming wood chips at high temperature followed by mechanical defibration, with mild chemical additives to enhance fiber separation. Classified under HTS 4705.00.00.00 due to the combined mechanical and chemical pulping processes. Ideal for graphic papers requiring high opacity.
Refiner Chemical Pulp (RCP)
Refiner chemical pulp (RCP) chemically treats wood chips before refining in pressurized refiners, a clear combination of processes. Classified under HTS 4705.00.00.00 for semi-chemical wood pulp. Used in tissue and towel products.
Softwood CTMP Pulp
CTMP made from softwood species like spruce or pine, using chemical-mechanical process for long-fiber pulp. Under HTS 4705.00.00.00 as combined pulping. Used for linerboard.
Hardwood Semi-Chemical Pulp
Semi-chemical pulp from hardwoods like aspen or eucalyptus via chemi-mechanical process. HTS 4705.00.00.00 for hybrid method. For tissue and fluff pulp.
Newsprint Grade CTMP
CTMP optimized for newsprint with specific freeness and opacity from combined pulping. HTS 4705.00.00.00 applies. Blended with deinked pulp.
Tissue Grade Semi-Chemical Pulp
Semi-chemical pulp for soft tissue, combining processes for bulk and softness. Under 4705.00.00.00.
Packaging Grade PGW Pulp
PGW for boxboard and packaging from hybrid process. HTS 4705.00.00.00.
High-Yield Bleached Pulp
High-yield (90%+) bleached semi-chemical pulp. 4705.00.00.00.
Eucalyptus CTMP
CTMP from eucalyptus for fluff pulp. HTS 4705.00.00.00.
Northern Softwood TMP
TMP from northern softwoods for graphic paper. 4705.00.00.00.
Recycled Fiber Blended CTMP
CTMP blended with recycled fiber for cost efficiency. Still 4705 for primary process.
Chemi-Groundwood Pulp (CGP)
Chemi-groundwood pulp (CGP) treats wood chips with mild chemicals prior to grinding between stones, combining chemical softening and mechanical action. It is classified in HTS 4705.00.00.00 for its hybrid pulping process. Commonly used in board and packaging grades.
Pressure Groundwood Pulp (PGW)
Pressure groundwood pulp (PGW) uses chemical impregnation of logs followed by pressurized grinding, blending chemical and mechanical methods. Falls under HTS 4705.00.00.00 as semi-chemical pulp. Suited for high-quality printing papers.
Bleached Chemi-Thermomechanical Pulp (BCTMP)
Bleached CTMP (BCTMP) undergoes chemical treatment, mechanical refining, and peroxide bleaching for brighter pulp. HTS 4705.00.00.00 covers this combined process pulp. Popular in lightweight coated papers.
