Short answer:<\/strong> IMDS-style material compliance for stamped parts should connect the finished part to the base metal, plating or coating, restricted substances, material certificate, drawing revision, part number, and customer reporting format. It is not the same as a simple RoHS or REACH statement, especially for automotive supply chains.<\/p>\n

Material compliance requests often arrive late, after samples are approved or after the buyer asks for production release. That creates delay if the supplier has not collected material certificates, plating chemistry, passivation details, or customer substance requirements. For stamped parts, the declaration should match the actual production route, not only the base coil material.<\/p>\n

Use this guide with the RoHS and REACH documentation guide<\/a>, material selection guide<\/a>, copper terminal plating selection guide<\/a>, and plating and passivation RFQ guide<\/a>.<\/p>\n

What to include in an IMDS-style request<\/h2>\n\n\n\n\n\n\n\n\n\n
Evidence<\/th>\nStamped part detail<\/th>\nRisk if missing<\/th>\n<\/tr>\n<\/thead>\n
Base material<\/td>\nGrade, standard, thickness, temper, supplier, and material certificate.<\/td>\nThe declared material may not match the approved coil.<\/td>\n<\/tr>\n
Surface treatment<\/td>\nTin, nickel, zinc, passivation, oil, cleaning residue, or coating system.<\/td>\nSubstances in plating or coating may be omitted.<\/td>\n<\/tr>\n
Part identity<\/td>\nPart number, drawing revision, mass, assembly level, and customer program.<\/td>\nThe declaration may be rejected or linked to the wrong revision.<\/td>\n<\/tr>\n
Supplier chain<\/td>\nMaterial mill, plating supplier, outside processor, and certificate owner.<\/td>\nMissing upstream data can delay approval.<\/td>\n<\/tr>\n
Format and deadline<\/td>\nIMDS ID, customer portal, spreadsheet, PDF package, or signed declaration.<\/td>\nThe supplier may prepare the wrong evidence format.<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n

Base metal is only part of the declaration<\/h2>\n

A stamped bracket made from stainless steel may be simple to declare if there is no coating. A plated terminal, spring contact, battery contact, or passivated component is different. The finished part can include copper alloy, plating layers, anti-tarnish treatment, cleaning residue, oil, adhesive label, hardware insert, or packaging-related restrictions.<\/p>\n

For assemblies or inserted hardware, check the stamped assemblies guide<\/a>, insert molding insert guide<\/a>, and lot traceability guide<\/a>.<\/p>\n
