Frequently Asked Questions

The value depends on the precious metals inside — Platinum (Pt), Palladium (Pd), and Rhodium (Rh). Use our online catalogue to find your catalytic converter model and get an instant estimate based on today's metal prices.

XRF (X-ray fluorescence) is a non-destructive scientific method that measures the exact metal content in parts per million (PPM). We point the XRF analyzer at your catalytic converter's ceramic core and get precise Pt, Pd, and Rh readings in seconds.

We use a transparent formula: metal content (from XRF) × weight × metal market price × recovery rate, minus company margin. You can see the exact breakdown on your receipt. The metal prices are updated twice daily from the London Metal Exchange.

We buy all types: gasoline, diesel, truck, and motorbike catalytic converters. Both ceramic and metallic substrate types. Our catalogue covers 130+ models from major brands including Honda, Toyota, Isuzu, and Mitsubishi.

From arrival to payment, the process typically takes less than 15 minutes. We weigh your catalytic converter, perform XRF measurement, calculate the price, and issue a receipt on the spot.
