Provide your destination port (e.g., Hamburg, Los Angeles, Tokyo) when you inquire — we will calculate FOB or CIF freight costs in real time based on order volume, weight, and current sea freight rates. Samples are typically shipped via DHL/UPS/FedEx, with freight calculated based on your actual destination. We also support shipping to your nominated freight forwarder in China.

Transit times vary by destination country. Once you provide your destination port, we will calculate the specific transit time based on current vessel schedules. Express courier sample delivery timelines are also calculated in real time based on your destination.

We provide warranty coverage for all products against manufacturing defects. The specific warranty period is negotiated based on customer requirements and order type — bulk OEM orders may qualify for extended coverage. We supply replacement parts and technical support during the warranty period. Warranty does not cover damage caused by misuse or improper handling.

Simply fill out the inquiry form above or contact us via WhatsApp/email. Our export team will respond with a product catalog and quotation within 24 hours. For OEM projects, we assign a dedicated project manager to guide you from sampling to final delivery.

A typical timeline: Inquiry response within 24 hours -> Confirm model/customization requirements -> Sample dispatch -> Sample approval -> Mass production -> Quality inspection & shipment -> Sea freight transit.

Every shipment includes a pre-shipment inspection report with photos. If quality issues arise, please provide photographic or video evidence promptly after receipt. Verified defects will be fairly compensated through mutual negotiation between both parties.
