Sony Music México

Sony Music México refers to Sony's manufacturing plant in Tlalnepantla de Baz, a municipality of the Mexican state of Mexico. This plant was previously involved in vinyl manufacturing from the 1950s as CBS Records and was renamed at the start of 1991 as part of Sony's global rebranding from CBS to Sony. Audio cassette manufacturing began in 1991, and CD manufacturing in 1994.

In 2004, Sony DADC México, S.A. De C.V., although the name Sony Music México continued to be used in the disc matrix. The plant was eventually closed in 2015.

Sony Music México can be identified by one of the following:
• "Mastered by Sony Music México" present in the CD matrix, usually accompanied by mastering SID code IFPI LE8*.
• "SMM" moulded into the inner plastic hub, usually accompanied by the mould SID code IFPI 64**.
• The combination of one of the matrix number formats described below with SID codes IFPI LE8* or IFPI 64**.

From approximately 1997-2004, discs manufactured at the plant contain a unique matrix number in the format:
• XXCDDA######
where XX is a variable two-character (letter or number) code, possibly identifying the client label/company.

From around 2004 onward, this was replaced by a new series of matrix number formats:
• CTDX ######
• DIDP ######
• DIDX ######

These matrix numbers can be added to the catalogue number field with the Glass Mastered At role for this plant. For example:

Fama (5) - Sin Duda
Matrix / Runout: 01CDDA001066 01 IFPI LE81 Mastered by Sony Music México
Glass Mastered At – Sony Music México – 01CDDA001066

Sekta Core / Royal Club - Royal Club - Sekta Core
Matrix / Runout: DIDX 112550 01 IFPI LE81 Mastered by Sony Music México
Glass Mastered At – Sony Music México – DIDX 112550

Majestic Downfall / The Slow Death - The Slow Death & Majestic Downfall
Matrix / Runout: DIDX1067929 01
Glass Mastered At – Sony Music México – DIDX1067929
[note Sony Music México is not specifically named in the matrix here, but is identified by its matrix number format and SID codes]

When IFPI 64** and/or SMM is stamped in the plastic hub, a Pressed By role can also be assigned to Sony Music México.

However, please note that the CTDX/DIDP/DIDX matrix numbers are also used by other Sony manufacturing plants including DADC plants, which can be identified by specific matrix patterns described and visualised on its profile (including several crosshair symbols ⌖ that are not present in Mexican glass masters), and by mastering SID codes IFPI L32*.

Examples:
Various - If You ♥ Dance

In such cases, please enter:
Glass Mastered At – DADC – DIDP-###### or DIDX-######
Pressed By – Sony Music México [only when IFPI 64** and/or SMM is present in the hub mould]
