Proteomic Identification Principles for Animal Hair Fibre Mixes
Proteomic LC-MS/MS quantifies animal hair blend percentages by measuring species-specific keratin peptide markers against isotope-labeled internal standards.
HS Code 510211
Tariff Classification
Harmonized System nomenclature designates the specific category for cashmere goat hair to regulate and track the international trade of raw or partially processed fine animal hair. Customs authorities rely on hs code 510211 to identify unprocessed or dehaired cashmere before it is spun into yarn or knitted into garments.
Commercial Definition
The description covers only the undercoat of cashmere goats, which comprises fine fibres with a mean diameter under nineteen micrometres. Regular coarse guard hair falls under separate tariff codes. This division protects the high-value market from cheaper wool imports.
Import Compliance
Shipments registered under this tariff code undergo inspections to verify the origin and prevent the mislabeling of yak or angora fibres. Importers must supply certificates of origin and laboratory test results to justify using hs code 510211 at the port of entry.
Dutiable Border
Processing stages alter the tariff classification of cashmere, and once the hair is carded or combed, it moves to another code. This ensures that only raw or sorted undercoat hair is logged under hs code 510211, creating a boundary that assists trade analysts in monitoring unprocessed raw materials. If a shipment contains combed tops, the load falls under a different category.
