First Identify What the \u201cLeather\u201d Actually Is<\/h2>\n<p class=\"zr-lead\">The answer is often yes for genuine leather and many PU-based synthetic leathers, but not every material sold as leather should enter a laser test. The base material, tanning chemistry, pigments, coating, backing and adhesive determine both the visible mark and whether a trial is appropriate.<\/p>\n<\/div>\n<div class=\"zr-two\">\n<article class=\"zr-card\"><span class=\"zr-number\">01<\/span><h3>Genuine leather: test after confirming the finish<\/h3><p>Full-grain, top-grain, split and other genuine leathers can respond differently because fibre structure, tanning chemistry, moisture, dye and protective finishes change carbonisation, colour shift, edge quality and odour. Treat each grade and finish as its own test condition.<\/p><\/article>\n<article class=\"zr-card\"><span class=\"zr-number\">02<\/span><h3>PU-based synthetic leather: conditional test candidate<\/h3><p>PU skins and coated fabrics may be suitable for controlled trials, but the PU layer, pigments, backing cloth, adhesive and additives can melt, bubble, discolor or delaminate.

PVC-containing constructions can generate hazardous decomposition products and can also damage extraction or machine components.<\/p><\/article>\n<article class=\"zr-card\"><span class=\"zr-number\">04<\/span><h3>Unknown \u201csynthetic\u201d or \u201cvegan leather\u201d: identify first<\/h3><p>Commercial names do not define the polymer.
