Aluminum deoxidizers are an essential auxiliary material in steelmaking, with sales linked to domestic steelmakers' crude steel output, giving the segment a relatively stable demand base.
Aluminum billets, in contrast, are benefiting from rising demand tied to lightweighting and eco-friendly trends across automotive, construction, and electronics end markets, but profitability is exposed to raw-material cost swings, particularly aluminum scrap prices.
Externally, US trade measures have emerged as a key variable.
In the US Department of Commerce's 2024 preliminary antidumping ruling on aluminum extrusions, Korean companies' dumping margins were set at 0% for Almex and 2.42% for Sinyang, significantly lower than competing countries such as China (up to 376.85%), Mexico (up to 82.03%), and Indonesia (up to 112.21%).
Based on this, KOTRA assessed that antidumping duties could be both a caution factor and an opportunity for domestic firms to absorb demand shifting away from Chinese suppliers.
Some non-responding Korean firms, however, were assigned a punitive 43.56% rate, though the overall industry impact was seen as limited given their minimal US export exposure.
Separately, in April 2026 the United States restructured its Section 232 tariffs on steel, aluminum, and copper, shifting from a metal-content-value basis to a full customs-value basis, with effects varying by product category.
Within Korea's aluminum extrusion and billet industry, several competitors including Igu Industrial, Choil Aluminum, and Namsun Aluminum operate alongside PJ Metal, which leverages long-standing deoxidizer supply relationships and billet manufacturing know-how as competitive advantages.
