PARS & PAPS: Truck Clearance at the Canada–US BorderPARS与PAPS：加美边境的卡车清关

When a truck crosses the Canada–US border, the goal is for customs to have reviewed the shipment before the driver reaches the booth. Two barcode systems make that happen: PARS northbound into Canada, PAPS southbound into the US. Same idea, opposite directions, different agencies.卡车跨越加美边境时，目标是司机到达关口之前海关已审核完货物。两个条码系统实现这一点：北向进加拿大用PARS，南向进美国用PAPS。理念相同，方向相反，机构不同。

Northbound into Canada: PARS北向进加拿大：PARS

PARS (Pre-Arrival Review System) is a CBSA process. The carrier assigns a PARS barcode to the shipment and sends the paperwork to the Canadian customs broker. The broker files the entry referencing that barcode; CBSA reviews it pre-arrival. When the driver presents the barcode at the border, the system already knows the answer — most trucks are released in minutes.PARS（预到达审查系统）是CBSA的流程。承运人为货物分配PARS条码并将文件发给加拿大报关行。报关行凭该条码申报；CBSA在抵达前审核。司机在边境出示条码时，系统已有结果——大多数卡车几分钟内放行。

When PARS isn't set up in time, the truck either waits at the border while paperwork catches up, or moves in bond to an inland sufferance warehouse for clearance there — both cost time and money.PARS未及时办妥时，卡车要么在边境等文件，要么保税转运到内陆临时仓库清关——两者都费时费钱。

Southbound into the US: PAPS南向进美国：PAPS

PAPS (Pre-Arrival Processing System) is the US CBP mirror image: the carrier assigns a PAPS barcode, the paperwork goes to a US customs broker who files the US entry, and the carrier transmits an ACE eManifest to CBP. As your Canadian forwarder we coordinate the truck, the documents, and the timing with your US broker — we don't file US entries ourselves.PAPS（预到达处理系统）是美国CBP的镜像流程：承运人分配PAPS条码，文件交给美国报关行申报美国进口，承运人向CBP传输ACE eManifest。作为您的加拿大货代，我们与您的美国报关行协调卡车、文件和时间——我们不直接申报美国进口。

What makes truck clearance go wrong卡车清关出问题的原因

• Invoice package sent to the wrong broker, or late — the #1 cause of border waits发票文件发错报关行或发晚了——边境等待的头号原因
• PARS entry filed but carrier eManifest missing (or vice versa) — both systems must agreePARS已申报但承运人eManifest缺失（或相反）——两个系统必须一致
• Commodity needing a permit (CFIA, etc.) discovered at the booth instead of at booking需要许可证的商品（CFIA等）在关口才被发现，而不是在订车时
• Driver arrives before the entry is on file — dispatch and filing must be synchronized司机比申报先到——调度和申报必须同步

On our cross-border trucking service, the truck and the Canadian customs work sit with one team, so the synchronization problems above simply don't get a chance to happen.在我们的跨境卡车运输服务中，卡车和加方报关由同一团队负责，上述同步问题根本没有机会发生。
