What changed: Shopify now lets merchants define return window overrides by market for specific collections, products, or variants; if an item matches multiple overrides the shortest one applies, and items marked final sale remain non-returnable regardless of any override.
Who is affected
The source doesn't explicitly name a business type, but the feature is configured in Shopify Admin under Settings > Policies, so it covers Shopify merchants managing market-specific return policies.
What it means for your business
For businesses using Shopify, this means they can set exception return periods for specific collections, products, or variants per market without changing their storewide default return window.
What to do
Go to Settings > Policies > Return and cancellation rules, select the market to modify, and set an override return window for the target collection, product, or variant; confirm that final-sale items are unaffected by any override.
When it takes effect
The source page itself gives no separate effective date; the changelog feed marks the post September 29, 2026, and the feature is already available.
