When your Amazon shipment shows "in transit", it usually means that your goods have departed from the place of shipment and are in transit. As for whether it has arrived at the warehouse, it needs to be judged according to the specific mode of transportation and route. Generally speaking, if Amazon's FBA (Fulfillment by Amazon) service is used, that is, the seller sends the goods to Amazon's warehouse, and Amazon will be responsible for picking, packing, delivery, collection, customer service and return processing, then your goods are likely to have arrived or will arrive at Amazon's warehouse.

You can use Amazon's seller platform or logistics tracking tools to check the specific location and status of your goods to find out whether it has arrived at the warehouse. If the goods have arrived at the warehouse, you may need some time to complete the warehousing operation before you can start selling. At the same time, please note that Amazon's warehouse may cause delayed arrival or failure to deliver goods due to various reasons (such as strikes, natural disasters, etc.). Please pay close attention to logistics information and prepare corresponding countermeasures.
