Quality Assurance Period (QAP) Explanation

1.    The Quality Assurance Period (QAP) is an important aspect of our commitment to ensuring the quality and reliability of our products. We understand that customers rely on our goods to function properly and meet their expectations. To demonstrate our confidence in our offerings, we provide a warranty period during which we take responsibility for any quality issues that may arise.
2.    The length of the warranty period varies depending on the type of product. Generally, for consumable components subject to wear and tear, such as abrasion parts, the warranty period is three months. For smaller components, the warranty period is typically extended to six months. As for major equipment and machinery, we offer a one-year warranty period.
3.    We also recognize that each customer's requirements may differ, and we are open to negotiation regarding the warranty period. If the buyer requests a specific warranty duration that differs from our standard policy, we are willing to discuss and accommodate their needs accordingly.
