How to Fix “Faltan atributos obligatorios de ficha técnica” in Mercado Libre

Every Mercado Libre category defines mandatory technical attributes. Missing BRAND, MODEL or COLOR prevents publication, and partially completed sheets lose ranking against complete competitors.

Why this happens

Technical root cause

Mandatory attributes are category-specific and identified by codes such as BRAND and MODEL. Store catalogs keep the same information in free-text fields or in the title, so no value maps to the expected attribute code.

Mercado Libre Marketplace reports it as Faltan atributos obligatorios de ficha técnica and applies: Listing blocked or published with reduced exposure.

Native CMS friction

  • Shopify

    Vendor approximates brand, but model and colour usually live in the title or in unstructured metafields.

  • VTEX

    Specifications exist per category but their names rarely match Mercado Libre attribute codes.

  • WooCommerce

    Attributes are optional taxonomies that differ per product, so coverage across the catalog is uneven.

Fixing it manually

  1. 1

    Open the target category in Mercado Libre and list its required attributes.

  2. 2

    Find the source field in your catalog that holds each value.

  3. 3

    Normalize values to the accepted option list, especially colour names.

  4. 4

    Republish and confirm the ficha técnica shows as complete.

Moneda no coincide con el site local de Mercado Libre

Regional sellers keep one base currency internally and expect conversion at publish time. The integration passes the base amount through, and locale formatting adds separators the API does not accept.

Combinación de variantes no válida para la categoría

Store catalogs allow arbitrary option names such as material, flavour or pack size. Mercado Libre rejects axes its category does not define, and it also rejects two variants that resolve to the same combination.

Invalid value [gtin]

Barcodes are stored as text and get mangled on the way out: spreadsheets strip leading zeros, ERP exports pad with spaces, and staff paste SKU codes or internal references into the barcode field.
