Why it matters
Amazon's variation system requires explicit parent-child structure. parent_sku connects child SKUs to a parent, which is how variants appear together on the product detail page. Without it, variants list as separate products.
Amazon's equivalent of item_group_id. Required when listing items with variants — without it, Amazon treats each size/colour combination as a separate ASIN rather than variants of one parent product. The customer-facing impact is significant: variants under one parent show as a single product page with variant selectors; ungrouped variants show as separate product pages with no relationship.
The structure: parent SKU has its own ASIN (the "group ASIN"), and child SKUs reference the parent. Amazon's variation theme (Size-Colour, Size-Colour-Material, etc.) determines how variants are grouped — all children must vary on the same set of attributes.
The pain point: changing variation theme after creating the parent listing is painful (effectively requires deleting and rebuilding). Plan the variation theme correctly the first time, especially for categories with complex variant structures like apparel.

FAQ
Does parent_sku get its own ASIN?
Yes — the parent has its own ASIN (the 'group ASIN'), distinct from child ASINs. Amazon's catalog shows the parent's ASIN as the public page URL.
