Packing & Delivery

Normally the goods will be shipped using 40’ open-top container and 40’ HQ container. If use 40’HQ, it need to do a steel pallet to pack the goods, then the whole pallet cargo will be pushed into container together, when you unload the goods, you will pull the whole pallet out of the container. In this case, the ocean freight will be cheaper but will increase the cost of pallet. Regarding the open-top containers, all the goods will be loaded one by one. In this case, the sea freight of 40’OT is higher than 40’HQ, but The steel pallet for 40’HQ needs to be charged. You can tell me your preference.
