HS Code 53.06 – Flax yarn

HS code 5306 is a 4-digit heading in the Harmonized System that covers: Flax yarn. Heading 5306 of the Harmonized System encompasses "Flax yarn," serving as a crucial classification for trade in spun fibers derived from the flax plant. This heading specifically covers yarn made entirely of flax, whether prepared for weaving, knitting, or other textile applications, and regardless of its fineness or twist. The scope includes single yarns, multiple (folded) or cabled yarns, and even those put up for retail sale, provided they are predominantly flax by weight. It delineates the boundary for pure flax yarns, distinguishing them from blends where other fibers might dominate. Key sub-categories within this heading often relate to the yarn's treatment (e.g., bleached, dyed, unbleached), its count (thickness), and its intended use, which influences its physical properties. This classification is vital for trade compliance as it dictates applicable duties, taxes, trade quotas, and regulatory requirements (such as labeling for fiber content). Misclassification can lead to costly delays, penalties, or even goods seizure. Historically, flax has been cultivated for millennia, and its yarn has been a cornerstone of textile production, particularly for linen fabrics renowned for their strength, absorbency, and breathability. Its trade significance persists in both traditional textile industries and emerging sustainable markets. This heading sits within Chapter 53, dedicated to "Other vegetable textile fibres; paper yarn and woven fabrics of paper yarn," and falls under Section XI, covering "Textile and Textile Articles." It directly follows the raw and processed flax fibers (5301) and sets the stage for woven flax fabrics (5309), illustrating the vertical progression of flax products in the HS nomenclature.

Flax yarn for weaving linen fabric, flax yarn for knitting apparel, bleached flax yarn, unbleached flax yarn, dyed flax yarn, high-count flax yarn for fine linens, low-count flax yarn for industrial textiles, multiple (folded) flax yarn, cabled flax yarn, flax embroidery yarn, flax yarn for upholstery, flax yarn for curtain fabrics, flax yarn for bed linen production, specialty flax yarn for technical textiles, organic flax yarn, recycled flax yarn, wet-spun flax yarn, dry-spun flax yarn, flax yarn put up for retail sale, industrial strength flax twine, decorative flax yarn, fine apparel-grade flax yarn, coarse flax yarn for canvas, blended flax yarn (flax predominant), linen-look flax yarn.

Common misclassifications for flax yarn often involve confusing it with other vegetable textile yarns. Traders might mistakenly classify flax yarn under heading 5307 (Yarn of jute or other textile bast fibres of heading 5305) or 5308 (Yarn of other vegetable textile fibres; paper yarn) if the specific fiber identification is not precise. The key distinction lies in the botanical origin and characteristic properties of flax versus jute, ramie, hemp, or other less common vegetable fibers. Another mistake is classifying blended yarns where flax is not the predominant fiber by weight; such blends might fall under headings for the other fiber (e.g., cotton yarn in Chapter 52 or synthetic yarns in Chapter 54/55) if the other fiber constitutes the highest percentage.

In 2025, the top exporters of HS code 5306 in UN Comtrade data were China ($265M, 50% of world exports), Italy ($63M) and Ethiopia (about $42M). World exports came to about $532M, 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 5306 in UN Comtrade data were Italy ($132M, 25% of world imports), India ($78M) and Portugal ($46M). World imports came to about $517M, 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 5306 is a 4-digit heading under Chapter 53 of the Harmonized System. The first 2 digits (53) identify the chapter, and digits 3-4 (06) specify the heading. This code contains multiple 6-digit subheadings for precise product classification.
