- Short answer
- Yes — a market can hold several catalogs, a same-type submarket adds its parent's, and price clashes go to the more specific catalog, else the lower.
- Submarkets
- Same type: catalogs combine and the submarket's price wins. Different type: the submarket's catalog overrides.
- Sub-region markets
- A country or region subtype in early access: only shipping is customized, and catalogs come from the parent market.
- B2B below Plus
- Up to 3 active catalog assignments across active B2B markets on Basic, Grow, Advanced; Plus unlimited.
- Retail markets
- Customizing their catalogs requires Shopify POS Pro or the Plus plan.
- Country or region
- No page we read on September 22, 2026 names a catalog limit for these markets.
What happens when a market has several catalogs?
Shopify's developer docs say that with many price lists and product assortments, "you can assign multiple catalogs to the same market".
For one product in several applicable catalogs at different prices, the Help Center's catalogs page says "the more specific price is used" (a submarket's beats its parent's); if neither catalog is more specific — two parent market catalogs, for example — "the lower price is displayed."
What goes into each catalog is a separate question, and so is which price shows when a B2B company location has several catalogs.
How do submarket catalogs combine with the parent market?
Market type — country or region, retail, B2B or channel — decides whether a submarket adds to its parent's catalogs or overrides them:
Catalog customizations are combined with parent market catalogs of the same market type, but override catalogs from a different market type.
For the same type, Shopify says "Products from all applicable catalogs are available to the customer", and where submarket and parent price a product differently, "the submarket's price is used."
A sub-region market — an early access subtype of country or region — takes no catalog of its own: there you "can customize only the shipping options", and catalogs are inherited from the parent market.
Which market types limit catalogs?
B2B markets share one cap below Plus: "On the Basic, Grow, and Advanced plans, you can have up to 3 active catalog assignments across active B2B markets", and "assigning the same active catalog to 2 active B2B markets uses 2 of the 3 assignments". On Plus, "the 3-assignment limit doesn't apply" — how the 3-assignment cap plays out by plan.
Retail is a plan gate, not a count: "Customizing catalogs to use with retail markets requires Shopify POS Pro or the Plus plan" — see what per-location prices need.
For a country or region market, no page we read on September 22, 2026 — Shopify's Help Center Markets and B2B catalog pages, its developer catalog docs, and its Markets and pricing pages — names a number of catalogs.
