How to Fix “Combinación de variantes no válida para la categoría” in Mercado Libre

Each category allows a specific set of variation attributes — commonly colour and size. Sending an unsupported axis, or duplicated combinations, invalidates the whole listing.

Why this happens

Technical root cause

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.

Mercado Libre Marketplace reports it as Combinación de variantes no válida para la categoría and applies: Publication rejected for the whole variant group.

Native CMS friction

  • Shopify

    Up to three free-text option names per product, none of them validated against a marketplace taxonomy.

  • VTEX

    SKU specifications can combine many axes, producing combinations no marketplace category accepts.

  • WooCommerce

    Global and per-product attributes mix freely, so identical combinations appear under different labels.

Fixing it manually

  1. 1

    Check which variation attributes the target category allows.

  2. 2

    Keep only those axes on the listing and deduplicate combinations.

  3. 3

    Publish unsupported axes as separate listings instead of variants.

  4. 4

    Ensure each variation has its own stock, price and picture.

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.

Faltan atributos obligatorios de ficha técnica

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.

Missing value [color] / [size] / [age_group] / [gender]

Variant options are free-text in every storefront. One catalog has Colour, another Color, a third stores the shade inside the title, and none of them carry age_group or gender at all.
