Tariff Boundary
Harmonized system legal provisions classify wool, fine or coarse animal hair, and horsehair yarns or woven fabrics for international customs duty assessment. Under tariff classification chapter 51, specific headings distinguish carded or combed wool, animal hair blends, and woven wool fabrics based on fiber weight percentages. The chapter governs animal fiber products, excluding raw hides, raw furskins, and textile materials covered under vegetable or synthetic chapters.
Animal Fiber
Customs declarations require precise fiber content laboratory testing to assign six-digit subheadings based on average fiber diameter and processing state. Applying tariff classification chapter 51 involves verifying whether wool fibers underwent carding or combing operations prior to spinning. Fine animal hair from cashmere goats or alpaca falls under distinct headings separate from sheep wool or coarse animal hair.
Blended fabrics are categorized according to the constituent textile material that predominates by weight. Legal note definitions dictate strict boundary thresholds between wool and other animal hair types.
Heading Division
Incorrect heading assignment results in customs penalties and shipment holds. Fiber blending errors alter duty rates at port entry points.
Import Compliance
Importers reference laboratory fiber composition reports to defend classification choices during customs audits. Correct application of tariff classification chapter 51 establishes legally compliant duty payments for imported wool textiles.
