We provide comprehensive manufacturing solutions including OEM Manufacturing (production according to your designs and specifications), ODM Services (complete product development from design to production), support for small-batch trial production (negotiable MOQ) and mass production, custom mold development, and private labeling services.

Sample lead time is typically 7-14 working days depending on product complexity. Sample costs are calculated based on material costs and labor but are refundable against future large orders. Samples are shipped at the customer's expense, usually via EMS, UPS, DHL, or FedEx, but customers can also use their own shipping agent.

Generally, we require 100pcs for MOQ, but this is negotiable.

We implement a strict quality management system including Incoming Quality Control (IQC) for raw materials, In-Process Quality Control (IPQC), and Final Quality Control (FQC). We also support third-party inspections (SGS) and hold ISO 9001 certification.

We offer a 36-month quality warranty period with a rapid 12-hour response time for urgent issues. We provide free repair or replacement (responsibility determined by the cause of damage) and cover return shipping for defective products (responsibility determined by the cause of damage).
