Harmonized System Code Classification

The first two digits of the HS code "54" represent Fibers and Articles of Fibers.

Specifically, Chapter 54 covers the following main contents:

• Natural fibers: such as cotton, flax, hemp, wool, silk, etc.
• Chemical fibers: such as polyester, nylon, acrylic, etc.
• Textile yarns, textile fabrics, non-woven fabrics, knitted or crocheted fabrics, etc.
• Ropes, cables, cords, and other fiber products.
• Special fiber products, such as filter fabrics, medical fiber products, etc.

Therefore, if the main component of the product is fiber or made from fiber, it is likely to be classified under Chapter 54.

To make a more accurate determination, it is also necessary to check the complete HS code and specific information about the product's material and use.

First four digits explanation: HS code: 5402

Classification description: Synthetic filament yarns (excluding sewing thread), not packed for retail, including synthetic filament yarns with a count less than 67 decitex.

Specific meaning: Refers to synthetic filament yarns that are not packed for retail, including synthetic filament yarns with a count less than 67 decitex.

Six-digit explanation: HS code: 5402.20

Classification: Synthetic filament yarns (excluding sewing yarn), not packed for retail, including synthetic filament monofilament yarns with a count less than 67 decitex.

Specific meaning: High-strength polyester filament yarns, whether or not stretched or heat-treated; multi-filament (folded) or cord.

Eight to ten digits explanation: HS code: 5402203050 Classification: Synthetic yarns (not for sewing), not packed for retail, including synthetic monofilaments with a count less than 67 decitex: high-strength polyester filament yarns, whether or not stretched: single yarn — over 920 decitex: monofilament; multi-filament yarns, with less than 5 twists per meter Explanation: This HS code belongs to synthetic yarns, specifically high-strength polyester filament single yarns, not packed for retail. The key features are: * Synthetic monofilaments with a count less than 67 decitex * High-strength polyester filament yarns * Single yarn * Over 920 decitex * Monofilament or multi-filament yarns, with less than 5 twists per meter

Examples of products: * High-strength polyester filament yarns used in industrial applications * Single filament yarns with high tensile strength * Multi-filament yarns with low twist for specialized uses * Monofilament products used in filtration or medical applications * Yarns with a count over 920 decitex, suitable for high-performance applications
