Fibres; synthetic staple fibres, of aramids, not carded, combed or otherwise processed for spinning
Heading 5503 — Synthetic staple fibres, not carded, combed or otherwise processed for spinning
Chapter 55: Man-made staple fibres
Plain-language overview
Use HS-6 550311 when importing or exporting synthetic staple fibers made from aramids that have not been carded, combed, or processed for spinning. For example, if you are shipping unprocessed aramid fibers for use in industrial applications, this is the correct code.
This HS-6 line specifically covers synthetic staple fibers derived from aramid materials, which are known for their high strength and thermal stability. In contrast, HS-6 550312 includes synthetic staple fibers made from other materials like polyamides, which serve different applications.
When classifying your products, note that fibers classified under HS-6 550311 are typically used in applications requiring durability and heat resistance, such as in protective clothing or aerospace components. If your fibers have been processed in any way, such as being carded or combed, you would need to look at different classifications.
Understanding the nuances between synthetic fibers can help ensure compliance with customs regulations and avoid potential delays. If you're unsure whether your product fits this category, consider consulting with a customs broker.
