The Union customs-space boundary used to decide where UCC customs rules and CBAM import logic apply.
Customs territory of the Union is the import-boundary geography behind customs and CBAM workflows. It separates whether goods are inside or outside the Union customs space; it is not simply “the EU market” in a commercial sense, but a Union Customs Code boundary that affects customs status and import procedures.

Customs territory of the Union is the territorial boundary used by EU customs law to decide whether goods enter the Union customs system. For CBAM, it helps locate the import event and release-for-free-circulation boundary.
Implementation records should capture territory field, import event, customs status, free-circulation decision, customs office, goods movement, origin/export country, declarant, EORI value, and relationship to CBAM-covered goods.
Customs territory of the Union is the import-boundary control for CBAM and customs evidence. Goods, declarations, actors, and CBAM obligations need to be linked to the event where customs status changes, not just to a seller, buyer, or shipping route.
