Summary of Key Points
A batch of 800G optical modules from Solis Optoelectronics, a subsidiary of Dongshan Precision (a core component for AI computing infrastructure), were stolen during cross-border transportation. Although the rumored value of the goods was nearly 200 million yuan, the actual production cost was much lower, and the company had insurance coverage. Subsequently, these modules appeared on the online marketplace Xianyu at an extremely low price (950 yuan compared to the regular market price of tens of thousands of yuan), attracting widespread attention. This incident has exposed security vulnerabilities in the cross-border logistics of high-end electronic components, the industry's blind spots regarding the targeting of high-value industrial products by the gray economy, and the issue of companies' risk management not keeping up with the upgrade in product value.
I. Event Overview: From Theft to Discount Sale on Xianyu
1. Theft Incident: In June 2026, Solis' DML optical chips and 800G optical module semi-finished products were stolen from overseas storage/transportation facilities. At the beginning of July, industry sources speculated that the stolen goods were worth 27 million US dollars (about 193 million yuan).
2. Company Response: Dongshan Precision only acknowledged the theft on July 23, stating that the rumored amount represented the retail price and that the actual production cost was much lower. The company also mentioned it had insurance coverage, which would cover the full loss and would not affect its profits (since it did not meet the mandatory disclosure criteria).
3. The Xianyu Incident: Shortly after, someone listed "brand new Solis 800G optical modules" on Xianyu for 950 yuan (just one-tenth of the regular price). The seller's IP address was located in Hong Kong, and they indicated that bulk purchases were possible but individual inquiries should be avoided. When asked if the products were stolen, the seller remained silent before taking the item off the platform.
4. Current Status: The company has not provided further clarification regarding the source of the goods on Xianyu, leaving the situation at the stage where the theft is confirmed and there is suspicion that the stolen items are being sold.
II. Why Did This Theft Become a Hot Topic?
There are three main reasons why this incident gained significant attention:
1. Extreme Contrast: 800G optical modules are essential components for AI computing, with regular channels selling them for tens of thousands of yuan each, but they were offered for just 950 yuan on Xianyu—this absurd situation is highly contagious.
2. Link to the High-Popularity of the Computing Industry: Dongshan Precision's net profit increased by 300% in the half-year due to its optical module business, leading to a surge in its stock price. The theft rumor caused stock price fluctuations, and thousands of investors were closely watching the potential gains or losses, making this case highly relevant.
3. Revealing Industry Blind Spots: People usually discuss AI in terms of technology and production capacity, but high-value, small, and easily portable optical modules turned out to be an ideal target for thieves. The difficulty in tracking these stolen goods highlights security vulnerabilities in cross-border logistics.
III. Why Are Optical Modules Such a Target for the Gray Economy?
There are three key reasons why optical modules are attractive to the gray economy:
1. High Value Density: A single ordinary box can contain dozens of 800G optical modules, with a total value of over ten million yuan (equivalent to half a warehouse's worth of regular goods). They resemble common electronic components, making them difficult to detect and offering a high return on a low investment.
2. Easy Liquidity: Optical modules are standardized products that can be used directly without brand restrictions or serial number locks. Small IDCs and service providers in North America often cannot obtain products from top manufacturers and are willing to buy them at lower prices, making them easy to sell.
3. Difficulty in Tracing: While phones and computers have unique serial numbers for tracking, optical modules are not registered individually during bulk shipments. Once disassembled and resold, the origin is almost impossible to trace, allowing them to blend into the second-hand market.
IV. Why Is Xianyu a Perfect Platform for Illegal Sales?
Xianyu's characteristics and logistics vulnerabilities contribute to this situation:
1. Low Entry Barriers: The platform is easy to use, and transactions can be conducted privately, allowing sellers to claim they are selling "engineering surplus materials" or clearing inventory without facing strict scrutiny.
2. Cross-Border Logistics Vulnerabilities: Domestic optical module manufacturers often use a model of "producing in China and transshipping through overseas warehouses." However, these warehouses typically handle general goods with basic security measures, making it difficult to detect high-value items. The long cross-border supply chain (including overseas warehouses, freight forwarders, and customs clearance) makes it challenging to prevent theft, and insurance is often the preferred solution.
V. What Lessons Does This Incident Teach the Industry?
1. Security Costs Will Rise: In the future, high-value optical modules may require electronic seals, real-time tracking, and additional security measures, which will increase shipping costs and be passed on to consumers.
2. Full-Chain Tracing Becomes Standard: High-end optical modules should have unique identifiers, allowing for complete traceability throughout the production, storage, transportation, and delivery processes to prevent theft.
3. Risk Management Must Keep Up with Industry Development: As domestic optical modules become more valuable, companies need to improve their risk management practices. Otherwise, the gray economy will continue to exploit these vulnerabilities, leading to increased hidden costs.
In summary, while the demand for AI-related products is growing, companies must not focus solely on expanding production capacity and securing orders. They also need to invest in physical security and risk management to protect their profits from being stolen by the gray economy.
