LTL/Full Truckload FBA Pallet Size Requirements UK – Is there a leeway?

Hey all! New Amazon Seller here.

We are about to order our product. We have to make an LTL/Full Truckload Shipment plan due to nature of the product.

Amazon Requirements for pallet size in UK is 1000x1200mm
Our pallets are 950x1150mm. This is basically a 50mm/5cm difference.

Do you think Amazon are likely to reject this order given the pallet size is a tad bit smaller than what they require?

Any experience and insight on this is greatly appreciated.
