HS Code for Elastic monofilament

Elastic monofilament is classified under HS code 540411. This code is part of Chapter 54, which covers man-made filaments, including synthetic and artificial textile materials. Heading 5404 applies to synthetic monofilament of 67 decitex or more and of which no cross-sectional dimension exceeds 1 mm. The subheading 540411 is specifically reserved for elastomeric monofilament. To be classified here, the filament must meet the technical definition of "elastomeric" provided in the Section XI notes of the Harmonized System. This requires the filament to be capable of being stretched to three times its original length and returning to no more than 1.5 times its length within five minutes of release. This classification is distinct from rubber products, as it focuses on synthetic textile polymers that possess elastic properties.

Products Included

• Spandex monofilament
• Elastane monofilament
• Polyurethane-based elastomeric filaments
• Synthetic elastic monofilament over 67 decitex
• Clear elastic monofilament for textile use

Common Misclassification

Elastic monofilament is frequently confused with HS code 400700, which covers vulcanized rubber thread and cord. However, if the material is a synthetic textile polymer rather than vulcanized rubber, it belongs in Chapter 54. Another misclassification is HS code 540419, which is for synthetic monofilament that is not elastomeric. Importers must verify the "elastomeric" recovery properties to justify the use of 540411.

FAQ

What is the HS code for elastic monofilament?

The HS code for elastomeric synthetic monofilament of 67 decitex or more is 540411.

What is the decitex limit for this classification?

The monofilament must be 67 decitex or more; if it is less than 67 decitex, it is typically classified as a multifilament yarn in heading 5402.
