Multi-region (US + UK + EU) vinyl shipping, Magento native?

Yes, via Magento Multi-Source Inventory (MSI), native since 2.3.0. Vinyl-specific multi-region matters because pressing-plant origin determines which warehouse gets the inventory, and shipping a 180g 2LP from the US to a UK customer often doubles the freight cost vs shipping from a UK warehouse.

Architecture:

• Sources per region, us_warehouse (e.g. Nashville, served by USPS Media Mail), uk_warehouse (e.g. London, Royal Mail Tracked), eu_warehouse (e.g. Berlin or Amsterdam, Deutsche Post / DHL eCommerce).
• Stocks per region, US stock includes US-only source, EU stock aggregates DE + NL + FR sources, UK stock is UK-only.
• Customer geo-routes via IP + currency selector to the appropriate stock. Cart shows accurate availability + accurate ship date from the right warehouse.
• Source-selection algorithms decide split-ship vs wait-ship. For vinyl, almost always split-ship, vinyl customers will wait, but they won’t pay $40 for international freight when a domestic warehouse has the item.

Multi-region pricing + currency: separate store views per region. EU in EUR with VAT-included, US in USD tax-excluded, UK in GBP. Same SKUs, different price visibility, different payment methods (Klarna in EU, Affirm in US, Clearpay in UK). Hreflang tags + canonical strategy keeps SEO clean across regions.
