In addition, the company supplies memory ICs, sensor ICs, microcontroller ICs, transceiver ICs, Ethernet ICs, Wi-Fi chips, wireless communication modules and connectors. Recycled materials include factory dead stock, project offcuts, distributor surplus stock, original unopened pallets, tube-packed and reel-and-tape materials. Only goods sourced through legitimate channels are accepted; materials of unknown origin are rejected. The standardised recycling process is as follows:

1. Sorting of Materials and Submission of Inventory List
Customers should sort the materials to be recycled and provide complete details: model number, brand, package type, batch/date code, quantity, packaging condition (pallet / reel / tube / loose), condition, and whether the items are original and genuine. The inventory list should be sent via email, online form or WeChat to the Mingjiada evaluation team; for high-value products, we recommend simultaneously providing photographs of the labels and packaging.

2. Professional Assessment and Quotation
The assessment team verifies the materials based on market conditions, scarcity, batch expiry dates, appearance and packaging integrity, and generally provides a quotation within 24 hours; for high-value or bulk materials, sample testing may be arranged upon consultation, utilising X-ray scanning, label verification and electrical testing to confirm the authenticity and integrity of the components.

3. Confirmation of Transaction Terms and Signing of Agreement
Both parties confirm the price, settlement currency (RMB, HKD or USD are all acceptable) and collection method; options include on-site inspection and collection or the customer dispatching goods to Mingjiada’s Shenzhen or Hong Kong warehouses. Following consultation, a recycling agreement is signed, clearly defining rights and responsibilities as well as inspection standards. In addition to direct cash payment, customers may also opt for consignment or commission-based sales arrangements to maximise returns on their materials.

4. Full Inspection upon Stocking and Payment Settlement
Upon arrival at the warehouse, the quality control team verifies the model, quantity and batch number, and conducts random checks on electrical performance and appearance to ensure the components are unopened, have not been refurbished and show no signs of oxidation or damage. Full payment is arranged within 24–48 hours of passing inspection, via bank transfer or in cash.

5. Compliant Disposal of Materials
Qualified, original chips are re-taped, vacuum-sealed to protect against moisture, and stored in our warehouse before entering the spot supply chain; defective, unsealed or oxidised materials are scrapped in accordance with industry compliance protocols to prevent defective chips from re-entering circulation.
