Aluminum extrusions look clean and harmless. But REACH compliance can be tricky, especially when coatings or inserts contain regulated substances.<\/p>\n

Aluminum extrusions may involve REACH-regulated chemicals in coatings, lubricants, or sealants. To ensure compliance, all materials used must be verified, not just the base metal.<\/strong><\/p>\n

To avoid legal risks and delays at customs, it\u2019s crucial to understand where REACH substances may hide in your aluminum profiles.<\/p>\n

What REACH substances may be present in extrusions?<\/h2>\n

Aluminum metal by itself is not on any REACH blacklist. But things added during extrusion \u2014 coatings, lubricants, plastic parts \u2014 can carry substances of concern.<\/p>\n

REACH-regulated substances may appear in paints, anodizing sealants, lubricants, or plastic inserts used in aluminum extrusions.<\/strong><\/p>\n

Aluminum extrusion production involves multiple materials and steps beyond pressing metal. Here\u2019s where REACH-listed substances might show up:<\/p>\n

    \n
  • Lubricants or cutting oils<\/strong> used during shaping or CNC processes <\/li>\n
  • Powder coatings or liquid paints<\/strong> for surface finish <\/li>\n
  • Konversiopinnoitteet<\/strong> like chromate treatments <\/li>\n
  • Plastic or rubber inserts<\/strong>, commonly used for assembly or sealing <\/li>\n
  • Sealants and adhesives<\/strong>, often applied during fabrication <\/li>\n<\/ul>\n

    Common chemicals to watch out for:<\/h3>\n\n\n\n\n\n\n\n\n\n
    Materiaalin tyyppi<\/th>\nExample REACH-related substances<\/th>\n<\/tr>\n<\/thead>\n
    Coatings (powder\/liquid)<\/td>\nLead compounds, cadmium, bisphenol A<\/td>\n<\/tr>\n
    Konversiopinnoitteet<\/td>\nChromium VI (hexavalent chromium)<\/td>\n<\/tr>\n
    Plastics\/rubbers<\/td>\nDEHP, DBP, DINP (phthalates), Bisphenol A<\/td>\n<\/tr>\n
    Voiteluaineet<\/td>\nPAHs, chlorinated paraffins<\/td>\n<\/tr>\n
    Adhesives\/sealants<\/td>\nIsocyanates, phthalates, epoxy hardeners<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n

    Many SVHCs (Substances of Very High Concern) are not in the aluminum, but in small surface treatments or non-metal parts. Even if the base metal is safe, the presence of one SVHC over 0.1% by weight triggers REACH obligations.<\/p>\n

    This is why responsible suppliers provide full material declarations<\/strong>, not just chemical composition of the alloy. It\u2019s also why buyers should ask for REACH compliance at the article level \u2014 meaning the full product.<\/p>\n

    <\/svg> REACH compliance only concerns the aluminum content<\/b>False<\/span><\/p>

    Coatings, lubricants, and plastic inserts can also contain REACH-regulated substances.<\/p><\/div>

    <\/svg> Sealants used in aluminum extrusion assemblies may include SVHCs like isocyanates or phthalates<\/b>Totta<\/span><\/p>

    These materials can trigger REACH obligations if used.<\/p><\/div><\/p>\n

    How is SVHC content measured in aluminum profiles?<\/h2>\n

    Some think testing the alloy is enough. But REACH looks at the whole article \u2014 including coating and inserts \u2014 not just the aluminum metal.<\/p>\n

    SVHCs are measured as a percentage of the total article weight. Tests focus on non-metallic parts like coatings or plastic components.<\/strong><\/p>\n

    Laboratories assess REACH compliance by looking at all parts of the finished product. Even if a profile is 95% aluminum, a thin layer of chromate coating or plastic insert could carry enough SVHCs to cross the 0.1% threshold.<\/p>\n

      \n
    • DEHP:n paino = 0,2 kg x 0,005 = 0,001 kg. <\/li>\n
    • DEHP-pitoisuus tuotteessa = 0,001 kg \/ 10 kg = 0,01 (1%) \u2192 ylitt\u00e4\u00e4 0,1%-rajan.<\/li>\n<\/ul>\n

        Tarvitaanko REACH-ilmoituksia jokaisesta l\u00e4hetyksest\u00e4?<\/h2>\n

        Jotkut asiakkaat pyyt\u00e4v\u00e4t REACH-todistusta joka kerta. Jos mik\u00e4\u00e4n ei kuitenkaan muutu, voit laillisesti k\u00e4ytt\u00e4\u00e4 samaa ilmoitusta uudelleen.<\/p>\n

            REACH allows this unless materials or suppliers change.<\/p><\/div><\/p>\n

            Can anodizing introduce REACH-regulated elements?<\/h2>\n

            Anodizing is widely used in aluminum finishing. But certain chemical sealants used in anodizing can carry REACH risks.<\/p>\n

            Anodizing is safe if it avoids hexavalent chromium. But if chromate sealing is used, the final product may contain REACH-listed substances like chromium VI.<\/strong><\/p>\n

            Anodizing forms a protective oxide layer. The risk comes during the final step: sealing<\/strong>. Some sealing baths include chromate<\/strong> compounds, which can leave a chromium VI residue. This compound is classified as an SVHC.<\/p>\n

            Types of anodizing and REACH relevance:<\/h3>\n\n\n\n\n\n\n\n\n

            How to stay compliant:<\/h3>\n
              \n
            • Ask anodizers to declare sealing chemicals<\/strong> <\/li>\n
            • Prefer chrome-free alternatives<\/strong> like hot water sealing <\/li>\n
            • Avoid any finish involving yellow chromate<\/strong> tai dichromate dips<\/strong> <\/li>\n
            • Run tests (e.g., XRF, ICP-MS) on surface layer if uncertain <\/li>\n<\/ul>\n

              Today, most exporters avoid chromate treatments for this reason. EU buyers may reject anodized parts without proof of chromium-free sealing.<\/p>\n
