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.
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.
