5301.10.00.00 - Flax, raw or retted

This HTS classification, 5301.10.00.00, specifically covers flax fiber in its raw or retted state. "Raw" flax refers to the harvested plant fibers before any significant processing beyond initial separation. "Retted" flax signifies fibers that have undergone a retting process, which is a method of loosening the fibers by biological or chemical means, typically by soaking in water or dew. This stage is crucial as it breaks down the pectin that binds the flax fibers together, preparing them for further mechanical processing but before any spinning or significant mechanical preparation has occurred.

It is important to distinguish this category from its sibling, 5301.20.00.00, which covers flax that has been broken, scutched, hackled, or otherwise processed but not yet spun. While 5301.10.00.00 focuses on the initial raw or retted state, 5301.20.00.00 encompasses more advanced mechanical preparation stages that further separate and align the fibers but still precede the spinning process. Additionally, 5301.30.00.00 covers flax tow and waste, which are byproducts or shorter, less refined fibers generated during the processing of flax, clearly distinct from the primary fiber covered here.

As 5301.10.00.00 is a leaf node within the HTS, there are no further subcategories. Therefore, classification within this code is determined by accurately identifying the material as flax in its raw or retted condition, without having undergone the more advanced processing described in sibling categories or being classified as tow or waste. Examples would include bundles of flax stalks that have been retted but not yet scutched or hackled, or the direct fiber obtained after initial separation from the plant without further mechanical refinement.
