Products classified under HTS 8448.33.00.00
Ring Spinning Machine Spindle
A precision-engineered spindle designed for ring spinning machines under heading 8445, used to twist and wind yarn onto bobbins during cotton or synthetic fiber spinning. It falls under HTS 8448.33.00.00 as a dedicated part solely for use with ring spinning frames. High-speed rotation ensures uniform yarn production in textile mills.
Spindle Flyer Assembly
The spindle flyer, a rotating component attached to ring spinning spindles, guides the yarn traveler and flyer during twisting in worsted yarn production. Classified under HTS 8448.33.00.00 as an accessory principally for heading 8445 machines. Essential for maintaining yarn tension and balloon control.
Cotton Ring Spinning Traveler
A small wire clip-on traveler for ring spinning rings, optimized for cotton yarns up to 30s Ne count, enabling high-speed yarn winding. HTS 8448.33.00.00 covers it as a ring traveler accessory for 8445 spinning machines. Replaceable design accommodates different yarn speeds and types.
Steel Spinning Ring
Durable steel ring mounted on ring spinning frames to guide the traveler during yarn twisting, typically 40-50mm diameter for worsted spinning. Falls under HTS 8448.33.00.00 as a principal part of heading 8445 machines. Grooved design reduces yarn hairiness.
High-Speed Synthetic Yarn Spindle
Lightweight spindle rated for 20,000+ RPM in synthetic polyester yarn ring spinning under heading 8445. HTS 8448.33.00.00 due to exclusive use in textile ring frames. Includes tension device for uniform winding.
