Q: What is the Minimum Order Quantity (MOQ) for wholesale or OEM orders?
A: We offer flexible MOQs. Standard bulk wholesale has a very low MOQ to support growing distributors. For custom OEM branding (like custom housing or logos), please contact our sales team for specific MOQ requirements based on the model.
Q: Can I get a sample before placing a bulk order?
A: Yes! We highly encourage distributors and brand owners to test our sample units to verify the torque, concentricity, and build quality before committing to a larger wholesale order.
Q: How does RHJC guarantee the quality and low defect rate for bulk micromotor orders?
A: We implement a strict, multi-stage Quality Control (QC) system. Every single micromotor undergoes continuous high-speed aging tests, torque stability checks, and heat dissipation evaluations before leaving our factory. Our rigorous testing ensures a near-zero defect rate, directly protecting your brand's reputation and significantly reducing your after-sales costs.
Q: Can you ensure stable supply and fast lead times for growing distributors?
A: Yes. As a source manufacturer, we maintain strong production capabilities and raw material inventory. This ensures we can provide stable, on-time delivery for repeated bulk orders, preventing any out-of-stock situations for your business.
Q: What is your warranty policy for B2B partners?
A: All RHJC jewelry micromotors come with a 1-year full coverage warranty. We provide comprehensive technical support and readily available replacement parts to ensure zero downtime for your clients.
