HS Code 55.07 – Artificial staple fibres, carded, combed or otherwise processed for spinning

HS code 5507 is a 4-digit heading in the Harmonized System that covers: Artificial staple fibres, carded, combed or otherwise processed for spinning. HS Code 5507 encompasses 'Artificial staple fibres, carded, combed or otherwise processed for spinning.' This crucial heading in international trade deals with man-made regenerated cellulose (artificial) staple fibres that have undergone preparatory processes like carding, combing, or other mechanical treatments to align and clean the fibres, making them suitable for subsequent spinning into yarn. It serves as an intermediate classification, bridging the gap between raw artificial staple fibres (like those in 5504) and the finished yarns of artificial staple fibres (like those in 5510). The scope includes various artificial fibres such as viscose rayon, modal, lyocell, acetate, and cuprammonium, provided they are in a form ready for spinning. This means they are no longer in their raw, unprocessed state but have been prepared as sliver, roving, or tow for direct feeding into spinning machinery. The boundaries are defined by the 'artificial' nature of the fibres (distinguishing them from synthetic fibres in 5506) and the specific 'processing for spinning' (distinguishing them from unprocessed fibres or finished yarns). Key sub-categories might implicitly include carded viscose sliver, combed modal roving, or lyocell tow prepared for spinning. For trade compliance, accurate classification under HS 5507 is vital as it directly impacts applicable tariffs, import quotas, and regulatory requirements, which can differ significantly from raw fibres or finished yarns. This heading reflects the globalized textile supply chain where specialized processing often occurs in different regions. Historically, artificial fibres like rayon revolutionized textiles, offering silk-like properties at lower costs, and their processed forms continue to be essential inputs for manufacturers seeking specific fabric characteristics. This heading is a foundational component of Chapter 55, which focuses entirely on man-made staple fibres, ensuring precise identification of these critical textile raw materials.

Common misclassifications under HS 5507 often arise from confusing the level of processing or the type of man-made fibre. Traders might incorrectly classify unprocessed artificial staple fibres (HS 5504) here, overlooking the critical requirement of being 'carded, combed or otherwise processed for spinning.' Conversely, processed synthetic staple fibres (HS 5506) are sometimes confused, neglecting the distinction between 'artificial' (regenerated cellulose) and 'synthetic' fibres. Another error is classifying finished yarns of artificial staple fibres (HS 5510), as 5507 specifically covers intermediate fibre forms, not spun yarns. The key is to meticulously examine the fibre type and the extent of processing.

In 2025, the top exporters of HS code 5507 in UN Comtrade data were France ($16M, 45% of world exports), Austria ($8.4M) and China ($3.8M). World exports came to about $36M, adding countries' reported figures and partner-based estimates for those that did not report (UN Comtrade data). Countries that did not report 2025 data are estimated from partner records, which can understate them.

In 2025, the top importers of HS code 5507 in UN Comtrade data were Morocco ($7.5M, 18% of world imports), Belgium ($6.9M) and Czechia ($5.7M). World imports came to about $42M, adding countries' reported figures and partner-based estimates for those that did not report (UN Comtrade data). Countries that did not report 2025 data are estimated from partner records, which can understate them.

HS code 5507 is a 4-digit heading under Chapter 55 of the Harmonized System. The first 2 digits (55) identify the chapter, and digits 3-4 (07) specify the heading. This code contains multiple 6-digit subheadings for precise product classification.
