A hydrogel line costs up to about 500 million won, employs 20 to 30 workers and occupies some 30 metres of floor [7]. At the exchange rate implied by the Korea IR Council's retail prices, the equipment is about $361,000 [1][2]. Hana Securities puts Genic's third-quarter revenue at 55.5 billion won [10]. The three lines Genic intends to run from October therefore cost, at the top of that range, roughly 2.7% of one quarter's projected sales [9][3]. Whatever is rationing these masks, it is not the price of the machinery.
The rationing sits on the labour side. Production requires blending, high-temperature coating, cooling, moulding, punching and sealing; brand-specific sizes, shapes and folding methods put a ceiling on automation; material is lost when masks are cut to a face shape; and defect rates move with an operator's skill [6]. Capacity therefore scales with trained people and with yield, neither of which arrives on a delivery truck. Cosmax is described as still working off early yield problems as it accumulates production experience [11]. That is the informative detail here: a large ODM holding the technology entered the category below yield.
The shelf corroborates the shortage. A four-pack at about $19 works out to $4.75 a sheet against $5 for a single, a discount of 5% [4][4]. Buyers taking four units are getting almost nothing for the volume, which is not how a category prices when lines are idle.
The customs series is where the caution belongs. Seven-month exports of $414.36 million are up 25.8% [1], while July alone rose 14.1% to $60.96 million [2]. Backing July out, the first six months grew 28.1% year on year against July's 14.1% [5]. One month is not a trend, and the series does not separate hydrogel from non-woven sheets, which are only described as one driver of the growth [16], so it cannot tell you whether that print reflects a supply ceiling, a base effect or mix.
Supply is now being added by six named makers, including Cosmecca Korea's four new lines at Cheongju [8][11]. Genic alone would go from eight lines to a planned fifteen, an increase of 87.5%, implying 300 to 450 people on this product at 20 to 30 workers a line [6][7]. Demand headroom is real: Park Jong-dae of Meritz Securities puts K-beauty export growth to Europe above 40% year on year [13]. But the $5 sheet is a scarcity price, and every line that reaches stable yield works against it. The disclosure that would settle this is output per line, and no one publishes it.
