Fastmarkets proposes to change Mexico non-ferrous scrap units

Fastmarkets is changing the units of its Mexico non-ferrous scrap price assessments to improve clarity and to align with prevailing commercial practices, per feedback from market participants.

The majority of submissions, transactions and references for these markets use kilogram-based prices, particularly across key regions such as Monterrey and Bajío. Converting these assessments to a peso per kg price reduces the need for unit conversion during market reporting, minimizes calculation discrepancies and reflects the format most frequently used by participants in Mexico’s non-ferrous scrap market.

Feedback from ongoing market engagement and price submission reviews shows consistent preference among suppliers, processors and buyers for kilogram-based pricing to better match invoicing and contract norms. This proposed change is therefore intended to improve usability and bring the series in line with broader Fastmarkets methodology standards.

Fastmarkets proposes to convert the following price assessments from peso/lb to peso/kg:

MB-AL-0422 Aluminium alloy A380.1, delivered to consumer Monterrey, Mexico, peso/lb
MB-AL-0423 Aluminium alloy A356.1, delivered to consumer Monterrey, Mexico, peso/lb
