Heavy Metal Testing refers to the process of detecting the content of harmful heavy metals such as lead, cadmium, mercury, and hexavalent chromium in products through chemical analysis methods. It is widely used in export fields such as toys, electronic appliances, textiles, and food contact materials. Usage scenarios include: meeting regulatory requirements such as EU RoHS, REACH, and US CPSIA, or environmental clauses in customer contracts. Precautions: Different markets have different limit values (e.g., EU RoHS limits lead to 1000ppm, CPSIA limits lead to 100ppm). It is necessary to clarify test standards (e.g., EN 71-3, ASTM F963) and test methods (e.g., ICP-MS, AAS); test reports must be issued by third-party laboratories, and attention should be paid to report validity and batch representativeness. Unlike 'heavy metal content', testing emphasizes the process and compliance verification; compared with single-item tests such as 'total lead testing', heavy metal testing usually covers multiple elements. In foreign trade, it is often used as a necessary document for customs clearance, bidding, or customer inspection.
📝 Examples
1. The customer requires us to provide a heavy metal testing report for this batch of plastic toys to prove compliance with the EU EN 71-3 standard. (Note: Used to meet customer compliance requirements)
2. Due to the update of US CPSIA regulations, we need to redo the heavy metal testing to ensure that the lead content is below 100ppm. (Note: Responding to regulatory changes and updating testing)
💡 Foreign Trade Tips
Foreign trade terms are the foundation of international business communication
Trade practices may vary slightly by country; pay attention when using them
When using terms in contracts, specify the applicable version (e.g., Incoterms 2020)
