Frequently Asked Questions

1. What is the minimum order quantity (MOQ) for OEM/ODM products?

Minimum order quantities vary depending on the product category and level of customization required. For standard OEM services such as logo printing and custom packaging, MOQs typically range from 100 to 500 units per model. For full ODM projects involving new mold development and custom design specifications, MOQs are determined on a case-by-case basis. We work closely with clients to find flexible solutions that align with their business scale and market entry strategy. Contact our sales team with your specific requirements for detailed MOQ information.

2. How long does it take to develop a custom OEM/ODM product from concept to delivery?

The timeline for custom product development depends on the complexity of the project. For simple OEM services such as logo placement and custom packaging on existing product lines, typical lead times range from 15 to 30 days after order confirmation and sample approval. For ODM projects requiring new mold development, custom design specifications, or unique functionality, the development timeline generally ranges from 60 to 120 days, including design, prototyping, testing, and mass production. We provide detailed project timelines during the quotation phase to ensure alignment with your business schedule.

3. What quality control measures does Ruina Optoelectronic implement during production?

Quality control is integrated at every stage of our manufacturing process. Incoming raw materials undergo inspection before production begins. During assembly, in-process quality checks are performed at critical control points. Each finished unit undergoes functional testing, including electrical safety tests, performance validation, and visual inspection before packaging. We also conduct random sampling for extended durability testing. Our 1,500-square-meter production facility operates under documented quality procedures, and all products are tested to meet the certification standards (CE, ROHS, FCC, UL, etc.) required for their target markets.

4. Does Ruina Optoelectronic provide after-sales support and warranty for international customers?

Yes, we provide comprehensive after-sales support for all international customers. Our standard warranty period is one year from the date of shipment, covering manufacturing defects. During the warranty period, we offer replacement units or replacement components for defective products at no cost. Our after-sales team provides technical support, troubleshooting assistance, and documentation for certification and customs clearance. For distributors and large-volume partners, we offer extended warranty arrangements and dedicated account management to ensure responsive support throughout our partnership.

5. Can I request product samples before placing a bulk order?

Absolutely. We welcome sample orders for product evaluation. Samples can be arranged with standard lead times, and customers cover shipping costs. For OEM/ODM projects, we provide pre-production samples for approval before mass production begins. Sample costs are typically refundable upon confirmation of a bulk order of specified quantities. We encourage sample testing to verify product quality, functionality, and packaging before committing to larger volumes. Contact our sales team with the specific models you are interested in to initiate a sample request.
