Compliance & Certification | Technical Application
Children’s products are far more safety-sensitive than adult products. As the core of the EU Toy Safety Directive, EN71-3 limits the thresholds of migratable heavy metals in materials such as colorants, directly affecting children’s health. Many toy, stationery, and baby product companies fail on their first return shipment because of heavy metal exceedances in pigment background. This article explains EN71-3’s control logic, testing points, and selection strategies, helping children’s product companies embed safety compliance into the front end of the supply chain rather than remediating after being stopped at customs.
I. What EN71-3 Governs
EN71-3 is Part 3 of the EU toy safety standard. It limits the thresholds of migratable heavy metals in toy materials (lead Pb, cadmium Cd, chromium Cr6+, arsenic As, antimony Sb, mercury Hg, selenium Se, barium Ba, etc.). It focuses on “the amount that can migrate out under simulated conditions of children’s saliva and gastric fluid,” not total content. This definition determines that the testing method is special and also means that material selection is more critical than post-hoc testing. Moving safety forward to pigment selection is the most effective means of eliminating exceedances at the source and the most responsible approach for children.
II. Migratable, Not Total Content
Unlike adult products, EN71-3 uses simulated extraction (acidic gastric fluid, saliva) to measure “migratable amount,” because children may bite or lick toys, and the heavy metals that migrate out constitute the real risk. Some substances have high total content but are difficult to migrate, so their risk is lower; conversely, easily migratable substances are dangerous even if total amounts are not high. Understanding this allows correct interpretation of test reports, avoiding being misled by “total content compliant” and truly guarding children’s safety bottom line, allowing compliance judgments to be based on scientific methods rather than surface numbers.
III. Pigment Background Is the Main Risk Source
The most common cause of heavy metal exceedance is that pigments themselves contain impurity metals (such as historical use of chromium-based and cadmium-based pigments). Even though modern pigments have improved, low-quality sources may still introduce them. At the selection stage, EN71-3 testing should be requested from suppliers rather than relying on finished product remediation. NAMEI selects low-heavy-metal pigments for children-related applications and provides testing support, building safety at the formulation starting point, helping toy companies avoid pitfalls and protecting their brands from being dragged
