AutoCatalyst Market is a unique resource where you can buy or sell catalytic converter, find out its real cost, based on Pt, Pd, Rh quotes, and see the most complete catalyst specifications. Our collection contains more than 25 thousand catalysts and more than 50 thousand photographs.

All prices are based on the exact composition of precious metals in the catalysts. How the AutoCatalyst Market website and mobile app works: 1. To sell a catalyst, find the serial number indicated on its body. 2. Enter this number in the search bar on our website. 3. Find out the real cost of the catalyst, depending on Pt, Pd, Rh quotes. 4. Sell it profitably to a buyer at the true price! AutoCatalyst Market has been operating since 2005. We started our activity in the automotive catalyst market with assembly, preparation for refining, and analysis of automotive catalysts in the European market. A solid team and strong management is the key to effective and quality work. This allows us to occupy leading positions in information component of the market. The company has gained extensive experience in the processing industry and has compiled a complete catalog of catalytic converters. It also invests in equipment for the processing, analysis, and recycling of catalysts. It is time to share experience and knowledge with our customers! Using our catalog you can: • simplify identification of old catalysts; • accurately determine value; • find partners in your region for a profitable sale or recycling of failed catalysts. The catalytic converter contains platinum group metals: platinum, palladium, and rhodium, which should be removed after the converter has reached the end of its life. Using professional equipment, we have collected accurate data on the content of precious metals. The cost of the catalyst is based on the utilization price: The number of pt/pd/rh precious metals is multiplied by the cost of metals and by the monolith weight. Then from the price are deducted: • manufacturing recycling costs; • 1% moisture; • losses during metal refining; • logistics costs.
