LUANKUN is an export company based in Zhangjiagang, Jiangsu. We source building products for overseas buyers and take care of the paperwork, inspection and shipping that sit between a factory order and a delivered container.
From a single enquiry to a loaded container.
Send a drawing, a sample or a specification. We identify the right manufacturing partner, confirm what can be made and quote against the confirmed build-up.
Your brand on the product, the packaging and the manual. We can also adapt an existing profile or furniture frame to your market, subject to a confirmed tooling and sampling stage.
We check the goods against the agreed specification before they leave the factory, and report with photographs, dimensions and any deviation we found.
We prepare the commercial invoice, packing list and shipping documents, and can add the certificates and legalisation your market asks for where the supplier provides them.
Doors, windows, furniture and fittings from different suppliers can be collected, checked and loaded into one container, with the loading plan sent to you before departure.
Claims are handled with the factory on your behalf, and replacement handles, hinges, seals, rollers and glazing gaskets can be added to your next shipment.
