Sertop

About

Sertop sp. z o.o. makes processed and fried cheeses at ul. Przemysłowa 58 in Tychy, in the Polish Silesian voivodeship.^[1] The Krajowy Rejestr Sądowy records it as SERTOP Spółka z ograniczoną odpowiedzialnością, KRS 0000099079, NIP 6460323825, REGON 270543286, seated in Tychy with share capital of PLN 2,793,000; its founding deed was executed on 4 July 1991 before a notary at the state notarial office in Warsaw, it was carried into the KRS on 14 March 2002 from the older RHB register, number 6814, at the district court in Katowice, and the register gives www.sertop.com.pl and [email protected] as its address data.^[2] The company dates itself to the privatisation in 1991 of the Zakład Wytwórczy Serów Topionych in Tychy, a plant commissioned in November 1973 after 33 months of building; it certified its quality system to ISO 9002 in 1996, introduced HACCP and gained approval as a dairy establishment for export to the European Union in 2003, and has held a BRC Global Standard certificate since 2007.^[3] Its 100 g cube prints SERTOP sp. z o.o., ul. Przemysłowa 58, 43-100 Tychy as the food business operator, the words Wyprodukowano w Polsce and the oval identification mark PL 24771601 UE.^[4]

GS1 company prefix 5900746 is recorded here as inferred, not sourced, because no source names its licensee. What points to Sertop: the company prints fourteen EANs under the prefix against its own 100 g cube flavours and further ones against its food-service packs, the 100 g cube carrying 5900746002038 names Sertop itself as the operator, and all 23 records Open Food Facts holds under the prefix are processed cheeses carrying the Sertop or SERTOP Tychy brand where a brand is typed at all.^[5][6][4][7] What was searched on 14 September 2026 and gave nothing: GS1 Polska's eProdukty catalogue, whose per-GTIN page is an empty JavaScript shell with no readable record and no public per-GTIN API;^[8] gs1pl.org, which serves an invalid TLS certificate and cannot be read; GEPIR and Verified by GS1, which publish no licensee data; web searches pairing the prefix with the company name, which return only retailer and Open Food Facts listings of Sertop articles; the company's own site, contact page, HoReCa catalogue and 2022 product catalogue, which print their own EANs but nowhere claim the prefix;^[6][9] and the current KRS extract, which carries no GS1 identifier.^[2] A later pass that finds a GS1, registry or company statement should move 5900746 to gs1_prefixes.
