Tariff Structure
International nomenclature standards established under the Harmonized Commodity Description and Coding System categorize flax, hemp, ramie, and other vegetable textile fibers under a dedicated two-digit tariff code. Statutory assignment under HS classification chapter 53 determines duty rates, trade statistics tracking, and import control policies for raw flax fibers, flax tow, spun yarns, and woven linen fabrics. Global customs authorities rely on this numerical hierarchy to identify traded plant-based textile commodities at import locations.
This classification system covers raw vegetable raw materials through woven fabrics, but excludes finished textile garments classified under chapters 61 or 62.
Subheading Division
Heading 5301 covers raw, retted, scutched, combed, or otherwise processed flax fiber alongside flax tow and waste. Heading 5306 specifies single or multiple flax yarns, distinguishing between unbleached, bleached, or dyed yarn categories. Heading 5309 governs woven fabrics of flax, split into subheadings based on flax mass content above or below eighty-five percent by weight.
Misclassification between raw fiber, yarn, and fabric headings alters statutory import duties and creates regulatory compliance liabilities for importing merchants.
Customs Assessment
Chemical fiber composition analysis and yarn construction tests verify correct product classification during customs entry reviews. Correct declaration under HS classification chapter 53 ensures compliance with international trade agreements and country quota monitoring. Legal customs declarations rely on accurate six-digit code selection supported by laboratory test certificates.
