Understanding product safety and compliance is essential for any beauty and skincare business operating in New Zealand. Whether you're sourcing cosmetic minerals, raw materials, or finished skincare products, access to independent laboratory testing and verified supplier documentation protects both your business and your customers.
Why Heavy Metals Compliance Matters
Cosmetic products—including mineral-based foundations, pigments, and skincare ingredients—can sometimes contain trace amounts of heavy metals. New Zealand's regulatory framework, aligned with international cosmetic safety standards, requires suppliers to provide documented evidence that their products meet strict limits for contaminants such as lead, cadmium, and arsenic.
Independent laboratory testing provides third-party verification that raw materials and finished products are safe for use. These compliance sheets document test results and confirm that suppliers meet NZ and international safety thresholds.
What to Request from Your Suppliers
When sourcing cosmetic minerals and raw materials, always ask your supplier for:
- Heavy metals compliance sheets — certified test results from independent laboratories
- Technical specification data sheets — detailed information on ingredient composition, particle size, and recommended usage rates
- Certificate of Analysis (CoA) — batch-specific test results confirming safety and purity
- Safety Data Sheets (SDS) — handling, storage, and safety information for raw materials
