What the sources say about these ties
- Mars, Incorporated owns
- Wikipedia names Mars Inc. as the producer of the Mars bar since 1932.
Built from the ownership rows on the brand and company pages, each cited where it is recorded. Made in is the country of production on this product's record; the GS1 prefix of a barcode names the issuing organisation, not where the product was made.
About this product
Mars Duo 78.8 g is the French-market pack of the Mars Duo, two 39.4 g Mars bars of milk chocolate filled with nougat (32%) and caramel (27%) in one wrapper.[1][2] The side panel names the importer as Mars Wrigley Confectionery, 3 Chemin de la Sandlach, Haguenau, with the French consumer number 0969 320 680, above a French-only ingredient statement.[1] Its table declares 1882 kJ / 448 kcal per 100 g and 742 kJ / 177 kcal per bar.[3] An earlier wrapper printed the same address under the importer's former name, Mars Chocolat France.[4]
The Duo is the two-bar pack that replaced the 84 g king-size Mars bar in Britain; the bar itself was first made by Forrest Mars Sr. in Slough in 1932 and is sold worldwide except in the United States.[5] The barcode's company prefix belongs to the group's French confectionery company: GS1's list of GDSN member companies carries GLN 5000159000000 against MARS CHOCOLAT FRANCE.[6] Amazon.fr lists the Duo only in lots of three and six bars labelled for Great Britain.[7]
Where it's sold
- The wrapper carries a French importer block marked "IMP: FR", the French consumer number 0969 320 680 and www.marsfrance.fr above a French-only ingredient statement and nutrition table.[1] France
A listing is evidence that this barcode is sold there, on that date; a price is what that listing showed, not a recommended price. Store links may be affiliate links (how this works).
