We fully recognize that the sustainable supply of spare parts is a fundamental commitment to our customers. AD has built a complete spare parts reserve system for all product lines, ensuring the long-term and stable supply of core wearing parts.

Every cooperative client is assigned a dedicated after-sales contact person. A fixed team follows up throughout the entire process from order delivery to after-sales handling, eliminating repeated problem explanations and fragmented communication.

For all after-sales issues, we adhere to the principle of "solving problems first, then tracing causes". Upon receiving customer feedback, we will immediately verify the situation and provide targeted solutions, including replacement, repair, and other compensation measures, prioritizing the protection of customers’ interests at all times.

Clear and reasonable warranty terms reflect our confidence in product quality. AD provides explicit warranty commitments for helmet shell structures and wearing systems. The warranty scope, applicable conditions, and processing standards are fully clarified and confirmed at the initial stage of cooperation.
