Threecolts 2.0

If you have multiple proposed shipments routed to the same FC, there are a few possible reasons why:

<a href="https://inventorylab.threecolts.support/en/articles/10415949" rel="nofollow noopener noreferrer" target="_blank">Due to recent changes with Amazon's API</a>, shipments are limited to 200 unique MSKUs per shipment. This means that Amazon will automatically split shipments up when they reach this limitation, and you will see two shipments routed to the same FC when this happens. ​ ​Note: This limitation only applies to the number of unique MSKUs allowed in a shipment. There is no limitation on how many units per unique MSKU can be added to a shipment. ​ ​

When listing through a third-party service such as InventoryLab, Amazon splits the shipments for any items that have different label types. They will not allow you to combine NO_LABEL, AMAZON_LABEL, and SELLER_LABEL into the same shipment in Stratify, even if they are routed to the same warehouse. ​ ​

If items are routed to an FC that accepts hazmat (dangerous goods) items, but only some of the items are categorized as hazmat, they will be split into separate shipments from the non-hazmat items. This is because Amazon does not allow hazmat and non-hazmat items to be shipped together. ​ ​

There is currently no way to combine shipments or add proposed shipments to existing shipment plans at this time unless you are shipping LTL using the Send to Amazon workflow.
