🏅 SGS Certification

What is SGS? SGS is the world's leading inspection, verification, testing, and certification company. When a product is SGS-tested, it means an independent, globally recognized laboratory has verified that it meets strict safety and quality standards — not just the manufacturer's word.

What we tested for: Our stainless steel products have been independently tested by SGS for heavy metal leaching, including:

  • Lead (Pb) — a toxic metal linked to serious health risks
  • Cadmium (Cd) — a harmful heavy metal found in some lower-quality metals
  • Nickel (Ni) — tested to ensure safe levels for everyday use

Our products passed all tests, confirming they do not leach harmful heavy metals into food or beverages.

🍽️ Food-Grade Safety

What does "food-grade" mean? Food-grade materials are those deemed safe for contact with food and beverages. They are non-toxic, non-reactive, and will not transfer harmful substances into what you eat or drink.

Our products are made from medical-grade 316 stainless steel — the same material used in surgical instruments and food processing equipment. This grade of steel contains molybdenum, which gives it superior corrosion resistance compared to standard 304 stainless steel, making it especially safe for acidic foods and beverages.

Why it matters: Many lower-cost alternatives use coatings, plastics, or lower-grade metals that can degrade over time and leach chemicals into your food. With Radiko, you never have to worry about that.

🔬 316 vs 304 Stainless Steel — What's the Difference?

304 Stainless Steel 316 Stainless Steel (Radiko)
Grade Standard / commercial Medical & surgical grade
Corrosion resistance Good Superior
Contains molybdenum No Yes
Safe for acidic foods Moderate Excellent
Used in Budget cutlery Surgical instruments & Radiko
Price point Lower Premium

Radiko uses 316 — because your family deserves medical-grade safety, not just the minimum standard.


🌿 Non-Toxic Materials

Our stainless steel is:

  • Non-porous — bacteria, mold, and odors cannot penetrate the surface, making it naturally hygienic
  • Non-reactive — it won't interact with acidic or alkaline foods, preserving the true flavor of your meals
  • BPA-free — no plastics, no coatings, no hidden chemicals
  • Free from lead, cadmium, and harmful nickel levels — independently verified by SGS testing

What you see is what you get: pure, clean stainless steel that's safe for your family and the planet.
