About HS Code 550311
This HS code covers synthetic staple fibers made from aramids, which are high-performance synthetic polymers known for their exceptional strength-to-weight ratio, heat resistance, and impact resistance. These fibers are traded in their raw, unprocessed staple form, meaning they haven't undergone further textile preparation like carding or combing. International trade is primarily driven by industries requiring advanced materials for protective gear, aerospace components, automotive parts, and industrial applications. Major importers include countries with strong manufacturing sectors in defense, automotive, and specialized textiles, while exporters are typically nations with advanced chemical and polymer production capabilities. The high cost and specialized nature of aramid fibers mean trade volumes are lower than commodity fibers, but their strategic importance is significant. Key considerations include fiber length, denier, and specific aramid type (e.g., para-aramid vs. meta-aramid), which dictate performance and application.
Products Under This Code
Para-aramid staple fiber, Meta-aramid staple fiber, High-strength aramid fiber, Heat-resistant aramid fiber, Ballistic-grade aramid fiber
Real World Examples
DuPont Kevlar staple fiber, Teijin Twaron staple fiber, Teijin Technora staple fiber, Hyosung Aramid staple fiber
Common Misclassification
This code is specifically for aramid staple fibers and should not be confused with aramid filament tow (550130) or aramid yarns (5402xx), as the form factor is crucial for classification.
Products Classified Under 5503.11
Industry
This code belongs to the Textiles & Clothing industry.
Trade Overview
The USA, Germany, and Japan are major importers and producers of aramid staple fibers, with China also emerging as a significant player.
