Products classified under Tariff item 4701.00
Bleached Mechanical Pulp (BMP) Aspen
Bleached Mechanical Pulp (BMP) from aspen hardwood is produced by mechanical refining followed by peroxide bleaching to enhance whiteness for hygiene papers. The process retains over 90% of the wood's original mass, as no significant chemical delignification occurs. This high-yield, lignin-rich pulp qualifies as mechanical wood pulp under tariff item 4701.00.00.
4701.00.00Chemi-Thermomechanical Pulp (CTMP) Softwood
Chemi-Thermomechanical Pulp (CTMP) from softwood involves a mild sodium sulfite pretreatment before thermomechanical refining, which improves brightness and strength while preserving most lignin. The chemical treatment is minimal and does not dissolve significant wood components, keeping the yield high. This pulp is classified as mechanical wood pulp under 4701.00.00.
4701.00.00High-Temperature Thermomechanical Pulp (HTMP)
High-Temperature Thermomechanical Pulp (HTMP) is produced by steaming softwood chips at temperatures above 160°C before mechanical refining, enhancing fiber separation and energy efficiency. The process is purely mechanical with no chemical additives, maintaining a high yield and lignin content. This pulp is used for packaging grades and falls under mechanical wood pulp in 4701.00.00.
4701.00.00Medium Density Fiberboard Pulp (MDF Pulp)
Medium Density Fiberboard Pulp (MDF Pulp) is produced by mechanically defibrating hardwood chips using steam explosion and refining, yielding uniform fibers without chemical digestion. It is used as a raw material for manufacturing medium density fiberboard, where the fibers are dried and pressed into panels. Because the pulp is obtained entirely by mechanical means and retains most of the wood's original components, it qualifies as mechanical wood pulp under tariff item 4701.00.00.
4701.00.00Newsprint Mechanical Pulp Blend
Newsprint Mechanical Pulp Blend combines thermomechanical pulp (TMP) and groundwood to optimize strength and deinkability for newsprint production. The blend contains only mechanically produced fibers with no chemical pulping, preserving high lignin content. This product is classified as mechanical wood pulp under 4701.00.00.
4701.00.00Northern Bleached Softwood Kraft Mechanical Pulp (NBSKMP)
Northern Bleached Softwood Kraft Mechanical Pulp (NBSKMP) is a high-yield pulp made from softwood chips using mechanical grinding with a mild chemical treatment, retaining significant lignin. Despite the 'kraft' in its name, it is not a kraft (chemical) pulp because the chemical step is minimal and non-dissolving. This pulp is used in tissue and specialty papers, falling under mechanical wood pulp in 4701.00.00.
4701.00.00Pressure Groundwood Pulp (PGW) from Fir
Pressure Groundwood Pulp (PGW) from fir is produced by grinding wood logs under pressure against a rotating stone, yielding pulp with excellent bonding properties for sack paper and board. The process is purely mechanical, preserving the wood's natural components and high yield. This classic mechanical pulp is classified under 4701.00.00.
4701.00.00Refiner Mechanical Pulp (RMP) Pine
Refiner Mechanical Pulp (RMP) from pine is made by refining softwood chips in a pressurized refiner without pre-steaming, producing economical pulp for newsprint with a natural wood color. The high lignin content provides stiffness for printing papers. This purely mechanical process qualifies as mechanical wood pulp under 4701.00.00.
4701.00.00Stone Groundwood Pulp (SGW) Unbleached
Stone Groundwood Pulp (SGW) unbleached is the original mechanical pulp, made by grinding debarked logs against a rotating stone to produce long fibers for wallpaper base and low-grade printing paper. The process retains all wood components, including lignin, with no chemical treatment. This unrefined pulp falls under mechanical wood pulp in 4701.00.00.
4701.00.00Thermomechanical Pulp (TMP) from Spruce
Thermomechanical Pulp (TMP) from spruce is produced by steaming wood chips at high temperature followed by mechanical defibration in refiners, preserving most lignin for strength and yield. This pulp is ideal for magazine paper and board due to its high bulk and print quality. The process is mechanical, with no chemical pulping, so it falls under 4701.00.00.
