Harmonized System Code Classification

The first two digits of the HS code "54" represent fibers and fiber products.

Specifically, Chapter 54 includes the following main contents:

• Natural fibers: such as cotton, flax, hemp, wool, silk, etc.
• Chemical fibers: such as polyester, nylon, acrylic, etc.
• Textile filaments, yarns, 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 refer to the complete HS code and the specific material and usage of the product.

First four digits explanation:
HS code: 5402

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

Specific meaning: Refers to synthetic filament yarns not packaged for retail sale, which also includes synthetic filament yarns with a denier less than 67.

Six-digit explanation:
HS code: 5402.45

Classification: Synthetic filament yarns (not for sewing), not for retail packaging, including synthetic filament yarns with a denier less than 67.

Specific meaning:

• Other yarns: refers to single or slightly twisted yarns with a twist not exceeding 50 turns per meter.
• Other: refers to yarns made from nylon or other polyamides.
• Other: further divided into filament yarns with a twist of 5 turns per meter or more (606).

8-10 digit explanation:
HS code: 5402459010
Classification: Synthetic filament yarns (not for sewing), not for retail packaging, including synthetic filaments with a denier less than 67: → Other yarns, single, untwisted or with a twist not exceeding 50 turns per meter: → Other, nylon or other polyamides: → Other → Single filament; multifilament, untwisted or with a twist less than 5 turns per meter: → Partly oriented multifilament
Explanation: This HS code belongs to synthetic filament yarns (not for sewing), not for retail packaging, which includes synthetic filaments with a denier less than 67. Specifically classified as other yarns, single, untwisted or with a twist not exceeding 50 turns per meter, other, nylon or other polyamides, other, single filament or multifilament, untwisted or with a twist less than 5 turns per meter, and partly oriented multifilament.

Examples of products: * Synthetic filament yarns made from nylon, used in industrial applications. * Non-woven fabric made from polyester filaments. * Knitted fabric made from polyester multifilament yarns. * Filter fabric made from synthetic filaments. * Industrial ropes made from polyester or nylon filament yarns.
