Sourcing Flexible duct from Dingtai Holdings Co., Ltd. - China Import Guide
Prior to placing an order, importers should confirm that the duct material matches the required galvanized steel grade and that the internal coating complies with local fire-safety regulations. Request a material test certificate and a fire-rating report that documents performance up to 150 °C without toxic emissions. Obtaining a short sample length for dimensional verification, especially the bend radius and connection compatibility, helps avoid later re-work.
Dingtai Holdings ships the product from its Qingdao facility, so buyers may consider FOB Qingdao or CIF Shanghai as the most convenient Incoterms. Because the supplier’s response rate is currently zero, it is prudent to negotiate a clear timeline for order acknowledgement and production lead time, particularly for large volume purchases. Clarify whether the 10 m rolls will be palletised on wooden pallets or shrink-wrapped, and ensure the packaging meets container loading requirements.
A third-party inspection before dispatch is advisable to verify duct dimensions, connection type and fire-resistance properties. Request a Certificate of Conformity and, if applicable, compliance with ISO 9001 or relevant national HVAC standards. Maintaining these documents will facilitate customs clearance and give the buyer confidence that the flexible duct meets the specified technical criteria.
