Certificates and Testing
Certificates and Testing: Manufacturer Documents and Quality Confirmation
Updated:
This page contains management system certificates (ISO) and official testing materials from partner manufacturers working with DD Tuning. These documents help customers and B2B partners quickly verify the transparency of origin, the presence of standardized processes, and the fact of product testing.
Important: ISO certificates (for example, ISO 9001/14001/45001) confirm that the manufacturer has implemented certain management systems (quality, environment, occupational safety, etc.). This is not a “certificate for each individual part” and does not replace proper compatibility selection or configuration verification for a specific vehicle.
How to read these documents
- ISO 9001 — quality management system: describes standardized processes, control, audit, and handling of nonconformities.
- ISO 14001 — environmental management: managing environmental impact and controlling production aspects.
- ISO 45001 — occupational health and safety: managing personnel risks and ensuring safe production processes.
- Testing/protocols — confirm that tests were conducted according to a specific methodology and that results are available (indicators/conclusions/test conditions).
If you are choosing a product for yourself, these documents are an additional argument in favor of predictable quality. If you work as a dealer/marketplace/drop-shipping partner — the documents help with compliance, product descriptions, and origin confirmation.

- ISO 9001:2015 (NINGBO SUMMER AUTO PARTS CO., LTD.) — view certificate (image).
Note: ISO 9001 confirms the manufacturer’s quality management system. It does not replace proper selection of wheel parameters (PCD/ET/width/CB) for a specific vehicle and configuration.
MRC (EuroCap): certificate (PDF)
Since 2019, DD Tuning has been developing this direction together with MRC (brand EuroCap). Below is a document used as confirmation of the manufacturer’s standards/processes in B2B communication.

FAQ: common questions about ISO and testing
Is ISO a guarantee of quality for each product?
No. ISO confirms that the manufacturer has an implemented management system (quality/environment/safety). It’s a strong trust factor, but in practice, proper selection, configuration, pre-shipment control, and correct installation are also important.
Why does the buyer need these certificates?
They increase confidence that the manufacturer operates according to standards, has audited processes, and documented procedures. For B2B, this is often critical: compliance, marketplace requirements, corporate procurement.
Is testing an “independent examination”?
It depends on the document. On this page, we publish official materials provided by the manufacturer (protocols/methodologies/results). Upon B2B request, we can additionally provide clarifications about test conditions if available in the documents or accompanying materials.
Contacts for B2B inquiries
If you need documents for a tender, marketplace, internal compliance, or corporate procurement — contact the DD Tuning sales department. We will help you select relevant files for your request (category/brand/market/format).
