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

From the packaging
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 2021-10-04 · printed

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).

markets · unknown: Searched amazon.fr on 2026-09-25 for "Mars Duo 78,8 g", "mars duo" and 5000159519328 (the store's own search answered with a bot challenge, so the searches ran through a web search restricted to amazon.fr): the only Duo listings are the lots of 6 (B013P4YLBG) and 3 (B013P4YIVO) of 78.8 g bars, both "Actuellement indisponible" and both giving Great Britain as the country on the label, so neither is this French single pack.
identity · unknown: Whether Mars still makes this French article is unsettled: no maker range page or French grocer listing carrying this GTIN was found on 2026-09-25, and the latest photograph is from November 2021.
