    "South Korea exported US$98.25 billion of goods in August, 68.7% more than a year earlier [E1]. Imports rose 22.5% to US$63.51 billion, leaving a US$34.75 billion surplus [E2]. Average daily exports climbed 72.5% to US$4.47 billion with half a working day fewer than a year earlier, and monthly exports stayed above US$90 billion for a third straight month [E1]. Korea Customs Service separately marked the August figures provisional in a release dated 1 September [E8].",
    "Semiconductor exports reached US$46.65 billion, up 209.0%, setting an all-time monthly record [E3]. The category cleared US$40 billion for a third consecutive month, with demand tied to expanding AI infrastructure spending by large cloud operators [E3]. Chips alone supplied 47.5% of the country’s export value, calculated from the reported totals [E1][E3]. Non-semiconductor exports rose 20%, giving the month a wider base around the dominant chip line [E1][E3][E7].",
    "Computer exports jumped 419.5% to US$6.24 billion, also a monthly record [E4]. Higher prices for NAND, a core component of enterprise solid-state drives, supplied part of that increase [E4]. Semiconductors and computers together generated US$52.89 billion, equal to 53.8% of all exports [E1][E3][E4]. The two hardware lines supplied more than half of every export dollar before the rest of industry entered the frame [E1][E3][E4].",
    "Petroleum product exports rose 65.3% to US$6.84 billion, and petrochemical exports gained 12.2% to US$3.86 billion [E5]. Higher unit prices linked to rising oil prices amid instability in the Strait of Hormuz drove the double-digit value growth [E5]. Physical export volumes fell 2.2% for petroleum products and 7.0% for petrochemicals [E6]. Korean exporters booked US$10.70 billion across those two lines on lower physical volumes [E5][E6].",
    "Fourteen of 20 key export categories increased, and the non-semiconductor basket rose 20% [E1][E7]. Steel gained 7.9% to US$2.11 billion, while general machinery edged up 1.8% to US$3.53 billion [E7]. Biohealth climbed 22.3% to US$1.41 billion and cosmetics advanced 52.1% to US$1.31 billion [E7]. Automobiles fell 29.8% to US$3.85 billion, and ships dropped 45.9% to US$1.69 billion [E7]. Exporters posted nominal gains across several categories, distributed unevenly around a dominant silicon core [E3][E7].",
    "Korean trade officials reported dollar values by broad product group [E1][E2][E3][E4]. They published no semiconductor unit series or HBM breakout in the English release [E3][E4]. The 419.5% computer gain therefore cannot be split among price, quantity and product mix from this release [E4]. The AI-hardware trail is visible at the border; the boxes remain closed [E3][E4].",
    "Semiconductors and computers supplied US$52.89 billion, or 53.8% of all exports, while petroleum and petrochemicals added US$10.70 billion in receipts despite lower physical volumes [E1][E3][E4][E5][E6]. This is an AI-hardware customs print with an oil-price valuation effect, not evidence of a uniform real-volume boom [E3][E4][E5][E6][E7]. Seoul’s record was written in silicon and thickened by dearer oil [E3][E5]."
