Multi-region, US vs EU coffee shipping (fresh vs CET cutoffs)?

Fresh coffee is a logistics problem as much as a roasting problem. The US vs EU split that matters:

• US, UPS Ground / USPS Priority typically delivers within 5 days. Roast Monday, ship Tuesday, customer brews Friday-ish, still inside the 7-28 day peak. East-coast roasters can hit West-coast customers in 3-5 days reliably.
• EU, intra-EU shipping is faster (1-3 days within the Eurozone) but customs adds days for UK-EU shipments post-Brexit. Roasters in Berlin / Amsterdam ship CET cutoffs (e.g. order by 3pm CET ships same day). Customers in the UK get a customs declaration; over £135 needs VAT collected at checkout via OSS/IOSS.
• UK, Royal Mail Tracked 24 is the default for under 2kg. DPD for heavier. Domestic UK to UK is 1-2 days; UK to EU is now 3-7 days with paperwork.
• Multi-warehouse, once you hit ~$3M GMV with split US/EU customer base, a second warehouse (e.g. Amsterdam for EU, North Carolina for US) is cheaper than international shipping. Magento Multi-Source Inventory (MSI) handles the source selection natively.

Magento store views per region: USD / VAT-exclusive for US, EUR / VAT-inclusive for EU, GBP for UK. Each has its own roast cutoff times (US Sunday for Monday roast, EU Tuesday for Wednesday roast). Shipping carrier integration via ShipperHQ or native Magento shipping modules. Customs duties auto-calculated via Avalara / Zonos for international.
