Core conclusions:From September 1 to 20, 2026, South Korea's exports reached US$71.4 billion, a year-on-year increase of 78.3%. Among them, semiconductor exports were US$34.1 billion, a surge of 259.4%, accounting for 47.8% of total exports, both reaching record highs for the same period in history. The demand for AI computing power is pushing the global chip industry chain into a new super cycle. What China factories are focusing on is not the news itself, but the string of supporting orders strung together behind it.
1. Look at the data clearly first
- Exports from September 1 to 20$71.4 billion, year-on-year+78.3%, the highest 20-day export performance on record
- semiconductor exports$34.1 billion, year-on-year+259.4%, also refreshing the same period in history
- Semiconductors account for total exports47.8%, hit a record high
- Exports to China doubled to$16.6 billion; Exports to the United States surge118%to $14.2 billion
- The three major destinations of China, the United States and Vietnam together account for % of total exports51.4%
- Imports increased by 26.7% year-on-year in the same period, with a trade surplus$22.97 billion

2. The three forces behind this round of surge
The first is the concentrated release of AI computing power investment.The capital expenditures of major cloud manufacturers and large model companies around the world continue to be revised upwards this year. Computing power construction has extended from "buying cards" to "buying storage, buying interconnection, and buying cooling", and the entire hardware chain has been pulled together.
Second, the memory chip price cycle reverses.Demand for high-bandwidth storage (HBM) and server-grade DRAM exceeds demand, and price increases and volume increases have pushed the export value of individual countries to historical highs.
The third is the industrial chain cluster effect.Semiconductors account for nearly half of South Korea's exports, which means that as long as this line thrives, the overall export data will be significantly amplified-which is why its growth rate seems so exaggerated.
3. Three-level impacts on China's foreign trade enterprises
Direct layer: Products that follow the AI hardware chain.Optical modules, printed circuit boards (PCBs), server structural parts, copper and aluminum heat sinks, and connectors are the most direct beneficiaries of this round. Exports of optical modules from Jiangsu, Sichuan and other places have increased significantly month-on-month.
Indirect layer: A supporting part of the computing power center.Cabinets, bus ducts, liquid-cooling pipelines, UPS battery racks, wire harnesses, these seemingly traditional hardware and sheet metal parts are being purchased in large quantities by data center projects, and their unit prices are higher than similar civilian products.
Spillover layer: AI hardware and cross-border e-commerce.The export of photovoltaic modules from January to August was 149.5GW. Cross-border e-commerce continued to maintain growth, and consumer products around AI hardware were also moving out simultaneously.
4. What are the risks of this kind of market
- Strong cycle attribute: Semiconductor export growth has obvious peak-valley characteristics in history. High growth rate is not equal to sustainable growth rate, and production scheduling should not be linearly extrapolated based on peak values.
- It's safer to replace slower categories: Industrial parts with long certification cycles and requiring proofing verification can withstand cycle fluctuations better than standardized electronic components.
- Don't just focus on one customer: The concentration of orders in the computing power chain is high, and the dependence on a single customer will be amplified when the market declines.
5. Common questions
Q: What does the surge in South Korea's exports have to do with my hardware factory?
A: Indirectly related. The construction of the data center requires a large number of cabinets, brackets, bridges, and heat sinks. These are supporting orders that can be undertaken by domestic factories. The key is whether you have been searched by overseas buyers.
Q: How to judge whether you can take such orders?
A: Let's look at two things first: First, whether the product can provide material certificates and third-party testing reports, and the second is whether the delivery date can be stable within the scope of the contract. These two factors affect whether you can enter the supply chain more than price.
Q: If you want to break into this chain, where do you start looking for customers?
A: Start with the purchaser with real import records and usecustoms dataScreening out overseas companies that have been purchasing similar categories recently, and then conducting targeted communication based on the pace of their projects, which is much more efficient than general group sending.
