Sales and purchase contract dispute between a technology company in Xiamen and its supplier

The plaintiff, a technology company based in Xiamen, entered into a "Custom Equipment Sales Contract" with the defendant, an equipment supplier from Shenzhen. The contract stipulated that the defendant would supply core production line equipment to the plaintiff, with a delivery period of 90 days from the signing date. However, the defendant delivered the equipment 120 days late and provided units with multiple quality defects. These issues prevented the plaintiff from launching production on schedule, resulting in significant costs for site rent, labor, and order breach penalties. The plaintiff has filed a lawsuit requesting the return of all payments made and compensation for all economic losses incurred.

The court ruled that the defendant committed a fundamental breach of contract and must refund the plaintiff the paid amount of 128 ten thousand yuan, compensate for economic losses of 86 ten thousand yuan, totaling 214 ten thousand yuan; the defendant shall bear all litigation costs and judicial appraisal fees.
