The EPS modules from Duolai Castle are considered "bulky goods"—they are light in weight but take up significant space. Due to the different house model styles you choose and the varying number of doors and windows, the quantities of EPS modules (numbered 1-12) will differ. Additionally, the modules feature hyperbolic curved arcs and come in irregular sizes, so the packing quantity will vary based on these factors. Typically, you need to select a house model first, and our engineers will calculate the packing quantity and recommend the most suitable shipping solution based on your choice.

For example: take the 28㎡ house model with 1 door opening and 2 window openings. One 40HQ container can hold 4 sets of EPS modules for this style, but auxiliary materials such as doors, windows, mortar, putty, and latex paint cannot fit inside. If you require these auxiliary materials from us, one 40HQ container can hold 3 sets of modules.

As a manufacturer of EPS modules, we entrust our partnered trading companies—who have import/export rights and are familiar with the customs codes and declaration processes for our products—to handle sales. For transportation, these trading companies typically coordinate with professional freight forwarders. The trading company will manage the export customs declaration for you, while the freight forwarder will handle logistics from the factory to the port, container loading, and shipping. Together, we form a professional service team, ensuring that from initial communication to the moment you receive the goods, a dedicated team supports you throughout the entire process until your order is completed. Of course, if you have long-term partners such as a designated trading company or freight forwarder, we will fully cooperate with them to ensure the smooth completion of your order.
