China Automotive Material Data System (CAMDS): What Automotive Companies Need to Know

The China Automotive Material Data System (CAMDS) is a regulatory data platform used in the Chinese automotive industry to collect information about materials used in vehicles and components. Similar to the International Material Data System (IMDS), CAMDS enables automotive manufacturers and suppliers to report detailed material compositions to support regulatory compliance and product approvals.

As China’s automotive market has grown into one of the largest in the world, regulatory transparency requirements for materials and substances have also increased. CAMDS plays a central role in this process by helping authorities and manufacturers track material composition, hazardous substances, and recyclability across the automotive supply chain.

What Is the China Automotive Material Data System (CAMDS)?

The China Automotive Material Data System (CAMDS) is a product data management platform designed specifically for the Chinese automotive industry. It enables manufacturers and suppliers to submit detailed information about the materials and substances contained in vehicle components.

The system was introduced following regulatory specifications issued by Chinese authorities that require automotive OEMs to provide material composition data as part of the vehicle type approval process. These requirements aim to increase transparency around hazardous substances, support environmental regulation, and improve lifecycle management of vehicles.

CAMDS operates as a centralized database where suppliers submit material data sheets (MDS) describing the composition of components and materials used in vehicles. This information is then made available to OEMs and authorities to verify compliance with Chinese regulatory requirements.

For global automotive companies, CAMDS represents an additional data reporting obligation alongside established systems such as IMDS.

Why CAMDS Matters for Automotive Companies

For companies operating in the Chinese automotive market, CAMDS compliance has become an important part of regulatory and supply chain management. Automotive OEMs must ensure that the materials used in vehicles comply with environmental and chemical regulations, and this requires reliable data from their suppliers.

As a result, CAMDS affects not only vehicle manufacturers but the entire automotive supply chain. Component suppliers, material producers, and system manufacturers may all need to provide detailed information about the substances used in their products.

From a business perspective, CAMDS supports several objectives:

• Ensuring compliance with Chinese automotive regulations

• Providing transparency about material composition in vehicles

• Supporting environmental and chemical substance management

• Facilitating vehicle type approval processes

• Improving traceability across automotive supply chains

Companies that supply components to Chinese OEMs typically need to integrate CAMDS reporting into their existing product compliance and material data management processes.

Key Challenges in CAMDS Data Management

Although CAMDS follows similar principles as other automotive material reporting systems, companies often face practical challenges when implementing CAMDS processes.

One of the main difficulties is the duplication of effort. Many global suppliers already collect detailed material data for IMDS. However, CAMDS uses its own system, meaning that companies must often provide similar information again in a separate platform.

Another challenge is the availability of supplier data. Material information must typically be collected across multiple tiers of the supply chain. If suppliers do not yet provide data in the CAMDS format, companies may need to recreate or manually transfer data.

Additional operational challenges include:

• Managing material data across global supply chains

• Ensuring data consistency between IMDS and CAMDS

• Handling confidential supplier information appropriately

• Maintaining data quality for complex product structures

• Adapting internal compliance workflows to additional reporting systems

For many companies, the transition to CAMDS therefore requires adjustments in both data governance and supply chain collaboration.

CAMDS and IMDS – Key Differences

Because many automotive suppliers are already familiar with IMDS, CAMDS is often compared to the international system. While both platforms serve similar purposes, they differ in governance and regulatory scope.

The International Material Data System (IMDS) was originally developed by global automotive manufacturers to standardize material data exchange across the industry. CAMDS, on the other hand, was introduced specifically to support regulatory requirements within China.

Some key differences include:

• Regulatory focus: CAMDS supports Chinese regulatory requirements, while IMDS serves global industry data exchange

• System governance: CAMDS is operated by CATARC, whereas IMDS is managed by an international automotive consortium

• Reporting scope: Both systems collect material composition data but may require different formats and processes

• Industry use: IMDS is widely used globally, while CAMDS primarily applies to vehicles sold in the Chinese market

For companies supplying to multiple regions, managing both systems effectively has become an important aspect of global automotive compliance.
