HS code for Stretch knit fabric: 6004.10

Fabrics, knitted or crocheted fabrics of a width exceeding 30 cm, other than those of heading 60.01, containing by weight 5% or more of elastomeric yarn but not containing rubber thread.

Classification of stretch knit fabric under HS 6004.10

Stretch knit fabric is classified under HS code 6004.10. This classification is governed by the technical specifications of the fabric's construction and composition. Under Chapter 60, which covers knitted or crocheted fabrics, heading 6004 is reserved for fabrics with a width exceeding 30 cm that contain at least 5% by weight of elastomeric yarn or rubber thread. Specifically, subheading 6004.10 is designated for those fabrics containing 5% or more of elastomeric yarn but specifically excluding those that contain rubber thread. Elastomeric yarn, commonly known by brand names like Spandex or Lycra, provides the necessary elasticity for modern apparel. The classification process requires a laboratory analysis or a detailed manufacturer specification to confirm that the elastomeric content meets the 5% threshold. If the fabric is wider than 30 cm and meets this chemical composition, it must be classified here regardless of the base fiber (e.g., cotton, polyester, or nylon).

Covers
  • Spandex-blend jersey knit fabrics over 30cm wide
  • Elastane-rich interlock fabrics for athletic wear
  • Stretch rib knit fabrics with high elastomeric content
  • Circular knit fabrics used for leggings and swimwear
  • High-performance compression knit fabrics

  • Speedo (for swimwear fabrics)
  • Nike Dri-FIT (for performance apparel)
  • Under Armour HeatGear (for base layers)
  • Victoria's Secret (for bra and shapewear fabrics)

Codes often confused with 6004.10

Common mistake. This code is often confused with HS code 6002.40, which also covers knitted fabrics with elastomeric yarn but is restricted to fabrics with a width not exceeding 30 cm (narrow fabrics). Additionally, if the fabric contains rubber thread instead of or in addition to elastomeric yarn, it should be classified under 6004.90. Another common mistake is using Chapter 54 or 55 codes, which are for woven fabrics, whereas 6004.10 is strictly for knitted or crocheted constructions.

Top exporters and importers of HS 600410 (the code used for stretch knit fabric), 2025

In 2025, the largest exporter of HS 600410 (the code used for stretch knit fabric) in UN Comtrade data was China, with 69% of world exports; the largest importer in UN Comtrade data was Vietnam, with about 26% of world imports. Taiwan did not report 2025 data, and its estimate from partner records misses its trade with other countries that did not report: in 2024 that was 72% of its exports here ($514M, CEPII BACI), so it may also belong among the top exporters.

Figures cover everything classified under HS 600410, not only stretch knit fabric.

How these figures are built

109 countries reported 2025 trade to UN Comtrade in HS 2022, and their own totals are used. Countries marked * did not, so their figures add up what other countries recorded trading with them, and their exports are valued at buyers' CIF prices. Those estimates miss trade with other non-reporting countries, so they can be low, and a non-reporting country can rank higher than shown or be missing from the list. World totals add both and leave out trade between two non-reporting countries. Figures are in current US dollars; reported imports are mostly valued CIF and exports FOB, and exports include re-exports. The UN Comtrade links show the underlying records; they can also list a few reporters left out here (regional groups and older HS editions).
