SKC Cassette Tapes

SKC Blank Cassette Tapes

SKC was founded in 1976 as Sunkyong Chemicals Ltd (선경화학), a subsidiary of South Korea's SK Group — the second-largest South Korean chaebol behind Samsung. Based in Seoul with its main plant and R&D center in Suwon, SKC developed polyester film as its first product, becoming the first Korean company to produce it using its own technology. In 1979, just three years after founding, SKC became the first Korean company — and only the fourth in the world — to produce magnetic tape for VHS recorders.

SKC's growth into audio cassette manufacturing was rapid and scale-driven. At their peak, SKC's audio cassette production reached 1.3 billion units per year, accounting for approximately 30% of global cassette output. This made SKC one of the largest cassette manufacturers in the world, and almost certainly the largest outside Japan. A significant portion of this production was OEM supply: SKC manufactured cassettes sold under the Memorex, Scotch, Radio Shack, and other Western brand names, making them a hidden presence in vast quantities of branded cassettes sold throughout the 1980s and 1990s.

Under their own SKC brand, the company produced a range covering all tape types. The CD Super Chrome (Type II) is particularly notable — Tapeheads community members praise it as an underappreciated high-bias tape, with performance described as comparable to premium Japanese Type II offerings. The GX and QX series cover standard and enhanced Type I.

SKC's full corporate name changed to SK Chemicals in 1998, and the magnetic media business was eventually divested. All surviving SKC cassettes are finite NOS inventory. Free US shipping on orders over $50.

Frequently Asked Questions

What is SKC cassette tape?

SKC was founded in South Korea in 1976 as Sunkyong Chemicals Ltd, a subsidiary of the SK Group (South Korea's second-largest chaebol). SKC became one of the largest cassette tape manufacturers in the world, producing 1.3 billion units per year at peak — approximately 30% of global cassette output — including OEM supply for Memorex, Scotch, and Radio Shack.

Did SKC make tapes for other brands?

Yes, significantly. SKC was a major OEM supplier to Western brands including Memorex, Scotch (3M), and Radio Shack / Realistic. A substantial portion of cassettes sold under those brand names in the US and Europe during the 1980s and 1990s were manufactured by SKC in South Korea.

How good is SKC CD Super Chrome cassette tape?

The SKC CD Super Chrome (Type II) is praised by enthusiasts as an underappreciated high-bias tape with performance comparable to premium Japanese Type II offerings. One Tapeheads member described it as similar in character to the JVC AF-II — low on bias noise, fresh-sounding, and genuinely competitive with better-known brands.

What happened to SKC?

SKC changed its full corporate name to SK Chemicals in 1998 when the parent SK Group rebranded from Sunkyong Group. The magnetic media business was eventually divested. SKC still exists today as a chemical and film company but no longer produces audio cassette tape.

Were SKC cassettes as good as Japanese tapes?

SKC's own-branded premium lines — particularly the CD Super Chrome — genuinely competed with Japanese mid-range and premium Type II offerings. The OEM production for Memorex and Scotch was calibrated to those brands' specifications. SKC represented the peak of Korean tape engineering capability.
