Regarding this question, if the dimensions of your Amazon products exceed 63 inches (length + width + height), they need to be shipped by special freight methods. You can complete the shipment by following the steps below:

1. Determine the special freight method: You can choose to use the special freight services of Amazon partners, such as Amazon Professional Freight or Amazon Global Logistics.

2. Estimate freight and delivery time: Calculate the freight and estimated delivery time based on the size, weight and destination of your products.

3. Pack the products according to Amazon's requirements: You need to pack your products according to Amazon's packaging standards to ensure the safety of the products during transportation.

4. Create a shipping plan: You need to create a shipping plan in the Amazon seller backend and fill in the relevant shipping information, including freight method, destination and transportation time.

5. Arrange pickup and delivery: According to your shipping plan, you need to arrange pickup and delivery, and ensure that the products arrive at the destination on time.

It should be noted that the freight for special freight methods is usually higher than that for standard freight methods. You need to reasonably consider the balance between freight and product costs.
