第一：最早的开始的时间
Starting
August 21, 2023, if you use a non-partnered carrier to send your FBA
shipments from China to the US, you can choose one of our ShipTrack
carriers, which automatically provide end-to-end tracking information in
Seller
Central.从2023年8月21日起，如果您使用非合作承运人将FBA货物从中国运往美国，您可以选择我们的ShipTrack承运人之一，这些承运人会自动在卖家中心提供端到端的跟踪信息。

ShipTrack carriers are vetted third-party providers that offer reliable tracking information.ShipTrack承运人是经过审查的第三方提供商，提供可靠的跟踪信息。

Using
ShipTrack carriers helps us predict when your shipment will arrive at
our fulfillment centers and generate more accurate estimated delivery
dates for
customers.使用ShipTrack承运人可以帮助我们预测您的货物何时到达我们的配送中心，并为客户生成更准确的预计送达日期。

Better
shipment tracking also helps you to make informed replenishment
decisions and reduce your overstock cost and understock
loss.更好的货物跟踪还可以帮助您做出明智的补货决策，并减少库存过剩成本和缺货损失。

When
you use a ShipTrack carrier, information on your shipment’s progress is
automatically provided to Amazon and available on the Shipment Summary
page.当您使用ShipTrack承运人时，货物进度信息会自动提供给亚马逊，并在货件摘要页面上显示。

For
a list of ShipTrack carriers for your China-to-US shipment, go to the
shipment creation workflow on Send to Amazon, and in the "Select
carrier" drop-down menu, select "Or use your own
carrier".要查看从中国到美国的货物的ShipTrack承运人列表，请前往“发送到亚马逊”的货件创建流程，并在“选择承运人”下拉菜单中选择“或使用您自己的承运人”。

By
the end of 2023, ShipTrack carriers will also be available for FBA
shipments from China to Japan and the
EU.到2023年底，ShipTrack承运人也将适用于从中国到日本和欧盟的FBA货件。
