Silla SG was founded in 1977 and listed on KOSDAQ in 1995 as a food manufacturing and distribution company, with Silla Holdings as its majority owner within the Silla Group family of listed affiliates that also includes Silla International, Wonil Special Steel, and Silla Textile.
Its core business consists of two pillars: fish sausage and other seafood processed food manufacturing, and seafood/meat (beef, pork) wholesale distribution. Since 2000, the company has supplied fish sausage to CJ CheilJedang under an OEM arrangement, maintaining a production system of roughly 4,500 tons annually.
It sells canned whelk under its own 'Dongpyo' brand, with the whelk canning business cited as maintaining production of around 1.1 million cans per year as a stable revenue source.
The company states it has secured HACCP certification and EU export processing facility certification, and operates a food research institute to build quality competitiveness.
In June 2026 the company entered a new business producing CJ CheilJedang's meat sausage products such as 'Round SPAM' and 'Big Sausage,' taking over some manufacturing equipment from CJ CheilJedang to minimize initial investment while leveraging existing infrastructure.
The company expects this new business to generate about KRW 6 billion in additional annual revenue, and stated that combined with existing fish sausage (about KRW 25 billion) and whelk business (about KRW 5 billion), total manufacturing revenue is projected to expand to roughly KRW 36 billion annually.
The heavy reliance on OEM supply to CJ CheilJedang means the relationship with this single customer has a significant bearing on results.
