Fastmarkets to publish additional kilogram-based prices for Mexico non-ferrous scrap assessments: pricing notice

Fastmarkets has decided to add peso per kg price units to its Mexican aluminium scrap, aluminium alloy and copper scrap assessments, to complement the existing peso per lb prices, effective from April 13, 2026.

The additional kilogram-based prices, to be calculated from existing pound-based assessments, are intended to improve clarity and align the assessments more closely with prevailing commercial practices in Mexico’s non-ferrous scrap markets.

Market participants commonly reference kilogram-based prices in submissions, transactions and negotiations, particularly in key regions such as Monterrey and Bajío. Publishing complementary peso per kg prices alongside the existing peso per lb assessments will reduce the need for unit conversion, improve usability and reflect the format frequently used by participants across Mexico’s recycling supply chain.

Feedback from ongoing market engagement and price-submission reviews indicates that many suppliers, processors and consumers in Mexico reference kilogram-denominated prices consistent with invoicing and contract practices. The additional units are therefore intended to improve transparency and usability while maintaining continuity with the existing assessments.

Fastmarkets proposes publishing additional price assessments in peso per kg for the following:

The additional peso per kg values would be calculated from the existing peso per lb assessments using a standard conversion factor of 1 kg = 2.205 lbs.

Please note that Fastmarkets previously proposed publishing only in kilograms in a notice published March 4 which you can view here.

Fastmarkets has instead decided to continue its existing assessments in pounds and add assessments in kilograms.
