Products classified under HTS 8439.99.10.00
Fourdrinier Paper Machine Wire Section Roll
A stainless steel roll used in the wire section of a Fourdrinier paper machine to support and transport the forming wire during paper formation. It falls under HTS 8439.99.1000 as a part specifically designed for machinery used in making paper or paperboard. These rolls ensure uniform paper web formation by guiding the wet pulp slurry.
Paper Machine Press Felt
A synthetic fabric belt used in the press section of paper machines to dewater the paper web by squeezing out water. Classified under HTS 8439.99.1000 as it is an essential part of paperboard making machinery. These felts are engineered for high pressure and durability in continuous operation.
Yankee Dryer Cylinder
A large steam-heated cast iron cylinder used in tissue paper machines to dry and impart finish to the paper web. It is a core component of paper making machinery, thus under HTS 8439.99.1000. These cylinders achieve high-speed drying through direct steam contact.
Paper Machine Headbox Slice
A precision-machined component that controls the flow and distribution of pulp slurry onto the forming wire in the headbox of paper machines. Falls under HTS 8439.99.1000 as a part of paper making equipment. It ensures uniform basis weight across the paper web.
Vacuum Box Cover for Paper Machine
A corrosion-resistant cover for vacuum boxes that remove water from the paper web in the forming section. Specifically designed for paper machinery, classified under HTS 8439.99.1000. These covers maintain vacuum integrity under wet, high-speed conditions.
Paper Machine Suction Roll Shell
Perforated stainless steel shell for suction rolls that dewater paper web through vacuum application. Essential part of paperboard making machinery under HTS 8439.99.1000. Hole patterns are optimized for specific paper grades.
Doctor Blade Holder for Paper Machine
Adjustable holder assembly for doctor blades that clean and control Yankee dryer surfaces in paper machines. Classified under HTS 8439.99.1000 as paper making machinery part. Precision oscillation prevents paper web sticking.
Paper Machine Shower Oscillator
Pneumatic oscillator that traverses high-pressure shower nozzles to clean forming wires and felts. Specific to paper machinery maintenance, under HTS 8439.99.1000. Prevents contamination buildup during production.
