Introduction – Why Heavy Metals Testing Matters
Heavy metals such as lead, cadmium, chromium, mercury, and arsenic may be present in textile and leather products due to dyes, pigments, or raw materials. Consequently, routine heavy metals testing has become an absolute necessity for modern manufacturing workflows. These chemical components are highly persistent and can cause severe health and ecological issues, making strict material screening standard practice for global market entry.
These metals are toxic and can cause serious health issues including organ damage, neurological disorders, and skin irritation.
What is Heavy Metals Testing?
Heavy metals testing is used to detect and quantify toxic metals in textile and leather products.
Common metals tested include:
- Lead (Pb)
- Cadmium (Cd)
- Mercury (Hg)
- Chromium (total & Cr VI)
- Arsenic (As)
Why is This Analytical Testing Important for Safety?
Key Reasons:
- Protect human health
- Ensure compliance with regulations
- Prevent toxic exposure
- Required for global trade
Risks of Non-Compliance:
- Product bans
- Regulatory penalties
- Certification failure
- Health hazards
Applicable Standards & Regulations for Heavy Metals Testing
- EU REACH Regulation
- OEKO-TEX® Standard 100
- CPSIA (USA)
- Various international safety standards
Heavy Metals Testing: Permissible Limits & Industry Values
Metal | Limit (mg/kg) |
Lead (Pb) | ≤ 90 mg/kg |
Cadmium (Cd) | ≤ 75 mg/kg |
Mercury (Hg) | ≤ 1 mg/kg |
Chromium (total) | Varies |
Arsenic (As) | ≤ 25 mg/kg |
