The first of those is set the moment your item lands on the pan. A scale reading even a fraction of a gram light on every weighing costs you across the whole sale, and you have no way of proving it after the fact. This is why a verified, legally-controlled scale is not a nicety but the foundation of the entire calculation. ## What does a legally certified scale look like in France? **In France, any scale used to buy or sell goods by weight must be a legal-metrology instrument: type-approved, verified when installed and re-verified periodically.** Commercial weighing instruments carry the CE conformity marking together with the metrology 'M' mark, and after each official check they bear a coloured verification sticker (the green sticker) showing the instrument passed and the year it is valid for. This regime is overseen by the State's legal metrology service, not left to the dealer's discretion. A reputable buyer will have the instrument in plain sight, will weigh your item in front of you, and will let you read the display yourself. If the scale is hidden, unmarked, or the weighing happens out of view, treat that as a red flag and ask to see the verification sticker. ## How can you check the weighing is honest before you sell? **Watch the weighing happen, confirm the display reads zero before your item is placed, and note the figure yourself.** Ask which fineness the buyer has assigned to each piece, because a hallmark (the French poinçon) or an acid or electronic test determines whether your item is treated as 750 or 585, and that choice moves the value as much as the weight does. Have mixed karats weighed separately rather than lumped together, so lower-fineness pieces are not dragged down or, worse, high-fineness pieces undervalued. Because the spot price is public and identical for everyone, the real variable is the buyback rate each dealer pays as a percentage of spot, which they are under no obligation to publish. A certified scale removes doubt about the weight so you can concentrate on comparing that rate.

The dealer must check your identity and enter the purchase in a police register, which also creates a paper trail tying the agreed weight and description to you. On tax, selling gold falls under either the flat-rate tax on precious metals or, if you can show proof of original purchase, the capital-gains regime. A clear weighing slip and an itemised breakdown of grams and fineness make it far easier to keep your own records straight for whichever route applies. ## Frequently asked questions Is a customs-certified scale a real thing when selling gold in France? The control is French legal metrology rather than customs specifically: commercial scales must be type-approved, CE and 'M' marked and carry a valid verification sticker. The practical point is the same, only weigh on an officially verified instrument. Can I bring my own scale to check the dealer's? You can weigh at home for reassurance, but a domestic scale has no legal standing. The reference for the transaction is the dealer's verified instrument, so focus on watching it read zero, weighing pieces separately by fineness and reading the display yourself. Does a certified scale mean I am getting a fair price? No. A certified scale only guarantees the weight is accurate. Value still depends on fineness and, above all, the buyback rate the dealer pays as a percentage of the public spot price, which varies between buyers and need not be published. ## Read also [ Guide Gold Buyback Payment: How and When You Get Paid in France ](https://meilleur-rachat-or.fr/en/guides/gold-buyback-payment-times-france/)[ Guide Selling Gold From Home in France: How a Home Visit Works ](https://meilleur-rachat-or.fr/en/guides/gold-home-visit-france/)[ Guide Troy Ounce to Gram: How to Convert When Selling Gold in France ](https://meilleur-rachat-or.fr/en/guides/troy-ounce-to-gram-conversion/) ## Sell at the best price near you Compare the gold buyers in your city.
