Notice of Real-Time Price Adjustment for Products

Shanghai Dada Electric Co., Ltd. has always been committed to providing our valued customers with high-quality electrical products and exceptional service. In line with our commitment to transparency and maintaining a sustainable partnership with you, we hereby issue this formal notice regarding a significant update to our pricing structure.

After careful consideration and thorough analysis of the evolving global market landscape, Shanghai Dada Electric Co., Ltd. will implement a Real-Time Price Adjustment Mechanism for our product catalogue, effective December 26, 2025. This strategic decision is necessitated by the unprecedented volatility and interdependency of several key factors directly impacting manufacturing and operational costs.

1. Rationale Behind the Implementation

The traditional fixed-price model, while stable, has become increasingly challenging to sustain without compromising the long-term reliability of our supply chain and the consistent quality you expect from us. The new mechanism is designed to address the following core market dynamics:

• Fluctuating Costs of Raw Materials: The prices of essential commodities such as copper, aluminum, steel, and specialized polymers—critical components in our products—are experiencing significant and rapid fluctuations on the global stage. These changes are driven by factors including geopolitical tensions, supply chain reconfigurations, and varying regional demand.
• Volatility in Energy and Logistics: The costs associated with industrial power consumption and global freight forwarding remain highly volatile. Unforeseen disruptions in logistics networks and regional energy market shifts contribute directly to our production and distribution expenses.
• Dynamic Currency Exchange Rates: As an international supplier, our procurement and sales activities involve multiple currencies. Exchange rate movements can have a substantial and immediate impact on our cost base.

2. How the Real-Time Price Adjustment Mechanism Will Operate

Our new system is built on principles of fairness, clarity, and responsiveness. It is not designed to introduce frequent, arbitrary changes but to ensure our pricing accurately reflects the current economic environment in a structured and predictable manner.

• Basis for Adjustment: Prices will be primarily indexed to a basket of publicly available, authoritative indices related to our core raw material costs, supplemented by major freight indices. A predefined, transparent calculation formula will be applied.
• Frequency and Communication: Adjustments will be made on a monthly or quarterly basis, depending on the product category and the severity of market movements. We will not apply daily changes. Any price revision will be communicated to all registered partners and customers via official channels, including this website, email newsletters, and direct account manager notification, at least fifteen (15) calendar days prior to the effective date.
• Quotation Validity: All new quotations generated after the effective date will clearly state their validity period (e.g., 30 days), within which the quoted price will be honored. Orders confirmed and paid for within the validity period will be secured at the agreed price.
• Online Platform Integration: Our official website and customer portal will be updated to display the most current prices. Each product page will include clear information on the last update timestamp and the key cost drivers influencing the current price point.

3. Our Commitments to You

We understand that change requires adaptation. With this new system, Shanghai Dada Electric Co., Ltd. reaffirms the following commitments:

• Transparency: We will provide regular market briefs explaining significant trends affecting our pricing.
• Advance Notice: You will receive ample notification before any adjustment takes effect, allowing for accurate project budgeting and planning.
• Consistent Quality: This adjustment is solely related to price. There will be no compromise on the superior quality, rigorous testing standards, or comprehensive warranties of our products.
• Dedicated Support: Our sales and customer service teams are fully briefed to address your inquiries. We are prepared to work closely with you on long-term project planning and framework agreements to provide greater cost predictability where possible.

4. Transition Period and Further Information

For ongoing projects and existing long-term agreements, specific terms will be honored as per the contracted conditions. Our team will reach out to discuss the transition where applicable.

We view our customers as strategic partners. This move towards a Real-Time Price Adjustment Mechanism, while responsive to market realities, is ultimately aimed at strengthening the resilience and fairness of our collaboration. It ensures we can continue to invest in innovation, maintain robust inventory levels, and provide the reliable service you depend on.
