The difference between EZWay preauthorization and case-by-case authorization lies in the timing of your confirmation. With case-by-case authorization, the customs broker files the declaration first, then pushes a notification to you, and you confirm "Declaration Confirmed" after the fact. With preauthorization, the broker must push the declaration details to you first, and customs will only accept the filing after you respond with "Declaration Confirmed." Taiwan Customs' official position is to recommend enabling preauthorization — the Customs Administration's press release dated 2022-09-21 explicitly recommends that consumers enable preauthorization to prevent impersonation and protect their own rights (go to App → "Member Profile Settings" → "Enable Preauthorization"; takes effect the following day). The trade-off is that once enabled, you must actively monitor and promptly respond to every push notification; otherwise your parcel cannot clear customs and delivery will be delayed. Some consolidation service providers recommend "not enabling" it for the sake of delivery speed — this reflects the provider's operational interest, not official government advice. Practical recommendation: if preventing impersonation is your priority, enable it (most effective), but you must be able to respond to push notifications in a timely manner. If you shop online frequently and worry about missing a notification, choose a consolidation service that proactively reminds you to confirm authorization (such as HowBridge Logistics) — balancing security and delivery speed.
