When it comes to dealing with a substantial collection of scrap catalytic converters, the pricing method you choose can impact your profits. Two common approaches used in the auto-catalysts recycling industry are pricing by assay and pricing per unit following a catalogue price list. In this article, we’ll examine these two methods and their respective advantages. By the end of this article, you will have a clear understanding of which strategy might be the most profitable for your specific circumstances.


Benefits of Assay-Based Valuations

Valuing a batch of scrap catalytic converters using assay-based methods, such as our Fast Settlement or Toll Refining services, offers several advantages:

Ensuring Fair Valuation

Ecotrade Group Catalytic Converter De-canningAssaying involves a detailed analysis of the precious metals contained within a batch of auto-catalysts. This precise assessment guarantees that you receive a fair and accurate valuation for the entire batch.

Transparent and Credible

Providing a detailed report with the assay results is expected from the buyer, as transparency is paramount in the recycling industry. This is the stage where the trust between customers and buyers is built.

Potential for Negotiation

With assay-based pricing, there may be room for negotiation, especially if you have a large batch. You can always request Toll Refining Terms from the buyer to get a good understanding of them for possible negotiations.


Benefits of Catalogue Price List Valuations

Pricing your scrap catalytic converters based on a catalogue price list also comes with its set of advantages:

Quick and Convenient

Catalogue price lists provide a fast and straightforward method to determine the value of catalytic converters. This method is time-efficient, making it an excellent choice for those prioritizing speed.

Minimal Costs

You won't incur additional expenses for assay testing, making catalogue pricing a cost-effective option for small suppliers.

Ideal for Smaller Batches

If you have a small batch of converters and want to save time, the catalogue price list method is ideal for quick valuations.



How is the assay process conducted?

The assay process involves processing the whole batch, extracting a small representative sample, and analyzing it for the precious metal content. This sample is then used to estimate the value of the entire batch, Learn more about Ecotrade’s sampling process here.

Is assay pricing suitable for small batches?

It is more commonly employed for larger quantities due to the detailed analysis involved. At Ecotrade, you can request assaying your material, even piece by piece, for any non-listed material in our catalogue or uncertain catalysts.

Can I trust the results of the assay?

Reputable assay facilities provide accurate results, but it's crucial to select a trusted and certified assayer for reliable valuations. Additionally, proper sample preparation made by trained experts is essential to guarantee accurate results. At Ecotrade Group, we employ XRF analysis and ICP as methods for assaying. Our sampling process is precise, measured and fully documented.

How do I find a reliable catalogue price list?

Reliable catalogue price lists can be obtained from reputable scrap metal buyers or recyclers. Ensure that the list is regularly updated to accurately reflect market prices. Our Eco Cat App is a price list that compiles more than 20,000 reference codes of catalytic converters, with scrap prices updated daily that align with PGM market prices.

Can I negotiate with buyers when using a catalogue price list?

Chances of negotiation are less likely than compared with assay pricing.

Is there a risk of undervaluing converters with catalogue pricing?

Yes, there's a possibility of undervaluing high-precious metal content converters with a catalogue price list. It's essential to consider this when using catalogue price lists. When in doubt, a non-destructive quick assay with an XRF Analyzer is the way to go.


In the industry of scrap catalytic converters, selecting the right pricing method is crucial for optimizing profits. Assay-based pricing offers precision and the potential for maximizing returns on high-value auto-catalysts. On the other hand, catalogue price lists are quick to get an estimate, making it ideal for small batches.

Your choice should depend on your batch size, time constraints, and the importance of precision in your business. Regardless of the method you choose, transparency, trust, and credibility should remain central to your business transactions.

It's important to remember that the scrap metal industry is constantly evolving, and staying informed about market trends and pricing methods is vital for continued success in this field. Don't miss out on any updates, subscribe to our Eco Cat Newsletter.
