Cashmere Authentication and Fraud Prevention
topic
Fraud issues: adulterant fibres include yak down (similar diameter, $30-50/kg), fine wool (16-19 μm, <$20/kg), synthetic microfibres (polyester, nylon), and viscose (all undetectable by consumers, requiring laboratory testing). Detection methods: fibre diameter analysis (OFDA, microscopy—cashmere ≤19 μm), DNA analysis (species identification—cashmere goat-specific markers), near-infrared spectroscopy (rapid screening, 95% accuracy), and SEM (scanning electron microscopy—scale pattern analysis). Estimated fraud: 30-50% of products labeled 'cashmere' contain undeclared fibre substitution or fail diameter requirements.
Role
Rampant fraud undermines consumer confidence and devalues genuine cashmere, driving regulatory enforcement (Italy fines for mislabeling up to €25,000, product seizure), industry self-regulation (ICCMHI voluntary labeling code), and brand authentication programs (DNA tagging, blockchain traceability) to protect legitimate producers and maintain market integrity.
