Products classified under HTS 8420.91.20.00
Paper Calendering Roll
A hardened steel cylinder designed specifically for use in supercalenders to impart a smooth finish to paper webs during the paper manufacturing process. It falls under HTS 8420.91.20.00 as a cylinder for calendering machines used in paper production. The roll's surface is precisely machined and often chrome-plated for durability against abrasive paper pulp.
Yankee Dryer Cylinder
A large cast iron cylinder used in paper machines for non-contact drying of tissue and towel paper grades by steam heating. Classified under HTS 8420.91.20.00 as a rolling cylinder integral to paper production machinery. Its polished surface ensures high heat transfer and paper release without sticking.
Soft Nip Calender Roll
A polymer-covered rubber roll paired with steel rolls in soft-nip calenders for high-bulk paper grades like tissue and linerboard. It qualifies for HTS 8420.91.20.00 due to its role in paper calendering machines providing controlled compression. The compliant surface prevents web breaks during rolling.
King Roll for Supercalender
The heated king roll serving as the bottom cylinder in multi-roll supercalenders for glossy paper and board finishing. Falls under HTS 8420.91.20.00 as essential for paper calendering with precise temperature control up to 150°C. Chrome-plated surface achieves mirror finish on supercalendered grades.
Matte Roll for Newsprint Calender
Reverse crown roll providing controlled gloss reduction in newsprint calenders for uniform printing surface. HTS 8420.91.20.00 applies as a specialized paper rolling cylinder with engineered crown profile. Surface texturing prevents excessive shine on high-speed newsprint grades.
Belted Calender Cylinder
Steel cylinder for extended nip belt calenders using polymer belts for soft compression in board production. Classified HTS 8420.91.20.00 for paperboard calendering applications. Provides shoe-press like nip without watermarks on coated grades.
Chilled Iron Paper Roll
Chilled cast iron roll with hardened shell for wear resistance in pulp dryer sections and calenders. HTS 8420.91.20.00 designation reflects paper machine rolling function. Pearlitic matrix provides 500-600 HB hardness for abrasive furnish.
Corrugator Roll for Linerboard
Precision-ground steel corrugating roll for medium formation in corrugated paperboard production lines. While primarily for corrugation, classified under HTS 8420.91.20.00 when functioning as paperboard rolling cylinder. Gear-driven with flute patterns matching A/B/C profiles.
Deflection-Controlled Paper Cylinder
Variable crown roll with hydraulic or thermal compensation for uniform line pressure across paper web. HTS 8420.91.20.00 for advanced calendering in high-speed paper machines. Maintains 50-150 N/cm lineal load consistency over 10m widths.
Laser-Engraved Calender Sleeve
Thin-walled steel sleeve with laser-etched pattern for textured paper surfaces in specialty calenders. Replaceable design for HTS 8420.91.20.00 paper machine cylinders. Provides embossed patterns for packaging grades without roll changes.
