Sterile Surgical Catgut Suture Raw Material
Raw catgut derived from animal intestines, specifically imported for further processing into sterile surgical sutures used in medical procedures. This falls under HTS 4206.00.13.00 because it is catgut intended solely for manufacturing sterile surgical sutures, distinguishing it from general catgut products excluded from Chapter 42 for finished sutures (heading 3006).
Goldbeater's Skin Catgut for Suture Twisting
Catgut reinforced with goldbeater's skin (ox pericardium layers), imported for twisting into multifilament surgical sutures. This qualifies for HTS 4206.00.13.00 as it meets the definition of gut articles specifically for sterile surgical suture production.
Bulk Twisted Catgut Precursor for Sutures
Partially twisted catgut strands from porcine intestines, for final sterilization and packaging as absorbable surgical sutures. HTS 4206.00.13.00 covers this as raw material imported explicitly for sterile suture manufacture, before sterile processing.
Sheep Gut Strands for Surgical Suture Fabrication
Longitudinally split and cleaned sheep gut strands, imported expressly for calibration and sterilization in suture production lines. HTS 4206.00.13.00 applies as catgut of animal origin designated for sterile surgical suture manufacturing, prior to final processing.
