HS Code 53.01 – Flax, raw or processed but not spun; flax tow and waste (including yarn waste and garnetted stock)

HS code 5301 is a 4-digit heading in the Harmonized System that covers: Flax, raw or processed but not spun; flax tow and waste (including yarn waste and garnetted stock). Heading 5301 covers "Flax, raw or processed but not spun; flax tow and waste (including yarn waste and garnetted stock)." This classification is fundamental for the initial stages of the flax supply chain, encompassing the raw material before it is transformed into yarn. It includes flax straw, retted flax (where the fibres are separated from the woody stem), scutched flax (mechanically separated fibres), and hackled flax (combed, parallelized fibres). The critical distinction is that the flax must not be spun into yarn, which would place it in heading 5306. The heading also explicitly includes flax tow, which consists of shorter, coarser fibres removed during scutching and hackling, and various forms of flax waste, such as yarn waste and garnetted stock, which are by-products of textile processing. This classification is vital for trade compliance as it accurately reflects the unprocessed or semi-processed state of flax, impacting duties, import regulations, and statistical tracking of primary agricultural commodities. Historically, flax has been cultivated for millennia, and its raw forms are essential for producing linen textiles, composites, and specialty papers. The heading's precise definition ensures that trade in this natural fibre, known for its strength and sustainability, is correctly categorized, supporting the global linen industry from cultivation to final product.

A common misclassification for products under 5301 is to confuse raw or processed flax with flax yarn, which falls under heading 5306. The key differentiator is whether the fibres have been spun into a continuous strand. Misclassifying unspun flax as yarn can lead to incorrect duty rates and compliance issues. Another mistake is confusing flax with other vegetable textile fibres, such as true hemp (5302) or jute (5303), or even ramie (5305). While all are natural fibres, their botanical origin is distinct, and the HS system requires specific identification. For instance, a shipment of scutched hemp might be mistakenly declared as scutched flax, despite having different physical and chemical properties and potentially different end-uses or regulatory considerations. Careful identification of the fibre type and its processing stage is crucial.

In 2025, the top exporters of HS code 5301 in UN Comtrade data were France ($941M, 52% of world exports), Belgium ($540M) and Egypt ($108M). World exports came to about $1.8B, 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 5301 in UN Comtrade data were China ($1.1B, 58% of world imports), Belgium ($288M) and India ($218M). World imports came to about $1.9B, 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 5301 is a 4-digit heading under Chapter 53 of the Harmonized System. The first 2 digits (53) identify the chapter, and digits 3-4 (01) specify the heading. This code contains multiple 6-digit subheadings for precise product classification.
