What we buy
Ceramic and metallic converters from cars, vans and trucks, diesel particulate filters (DPF/FAP), loose monoliths and broken ceramic.
Buying · Used converters, particulate filters, monoliths
An old catalytic converter is not scrap. It is a raw material.
Every vehicle catalytic converter contains platinum, palladium or rhodium – often only a few grams, but at prices quoted in euro per ounce. Tux Tap buys used converters, monoliths and particulate filters from workshops, dismantlers and private sellers, and values every piece by type, condition and the price of the day. In writing, traceable, paid by bank transfer.

Four things worth knowing before you sell
How we value
By manufacturer number, design, weight and the condition of the monolith – larger lots by laboratory assay on request.
Who sells to us
Garages, exhaust centres, car dismantlers and scrap dealers – and private sellers with single pieces.
What we need
Photos, the number on the shell, the approximate quantity and your location. Nothing more is needed for a first estimate.

Background
Why a catalytic converter is worth money
A catalytic converter turns harmful exhaust gases into less harmful ones. To do so, the honeycomb inside – the monolith – is coated with a very thin layer containing platinum, palladium and rhodium. Petrol engines rely mainly on palladium and rhodium, diesel oxidation catalysts mainly on platinum and palladium.
How much precious metal a piece contains depends on the vehicle, the year and the manufacturer. Original parts (OEM) usually carry far more metal than aftermarket replacements. That is why we ask for the number on the shell and for photos – and why two converters that look alike can fetch very different prices.
Recycling closes the loop: the metals are recovered in specialised refineries and used again in new converters, in electronics or in medical technology. For you this means that a part which would otherwise be sold as mixed scrap is paid for according to its actual metal value.
The value is not in the steel, but in a very thin layer inside.
Metal prices
What determines the price
No two converters are alike. These six points decide the offer – and which details we need from you.
All categories we buy
01
Manufacturer number
Identifies the type and its usual precious metal loading. The single most important detail.
02
Design
Ceramic substrates are usually the most valuable; metallic substrates and particulate filters are valued differently.
03
Condition of the monolith
Complete, broken, melted or empty – missing ceramic means missing metal.
04
Original or aftermarket
Aftermarket converters usually contain only a fraction of the precious metal of an original.
05
Daily price Pt / Pd / Rh
Market prices in euro determine the value of the contained metals on the day of the offer.
06
Quantity
Larger lots can be settled after sampling and laboratory assay.

How much is my catalytic converter worth?
That depends on the type, the condition of the monolith and the daily price of platinum, palladium and rhodium. Send us photos and the number on the shell – and we will give you a concrete price range.
Why are there no fixed prices on the website?
Because precious metal prices change every day and two similar converters can contain very different amounts of metal. A list would be outdated the next day. Instead, you receive a written offer with a date.
What is an aftermarket converter and why is it worth less?
Aftermarket converters are replacement parts from the accessories trade. They usually meet the emission standard with much less precious metal than an original part. We still buy them – but at a correspondingly lower price.
Do you buy diesel particulate filters (DPF/FAP)?
Yes. Some filters are coated with platinum and have real metal value, others hardly any. From the number we can tell you honestly what to expect.
Send us a photo.
Three pictures and – if legible – the number on the shell are enough for a first estimate. We reply in writing, usually within one working day.
