The highest grades feature long, fine fibers best suited for spinning into yarns and textiles, while lower grades find use in coarser products like ropes and matting. Proper grading is essential for maintaining market value and customer satisfaction.

Fiber Grade	Characteristics	Typical Applications
Grade 1 (Tow)	Longest, finest fibers; minimal impurities	High-quality ropes, yarns, textiles, paper
Grade 2 (Bourgoine)	Medium length, moderate fineness	Ropes, twines, wall coverings, backing for carpets
Grade 3 (Jute)	Shorter, coarser fibers; more impurities	Matting, sacking, coarse ropes
Grade 4 (Scrap)	Very short, fragmented fibers; significant impurities	Paper pulp, compost, filler material

The resulting fibers, now categorized, are then baled and prepared for transport to manufacturing facilities where they will become a diverse range of products. The efficiency of the entire process, from cultivation to grading, directly impacts both the cost and the environmental footprint of sisal production.
