Mold Marking Regulations by Region: Date Codes & Recycling
Key Takeaway: Automotive molds need date codes per IATF 16949 worldwide. Medical molds need lot traceability per FDA (US) or MDR (EU). Packaging molds need recycling marks per ASTM D7611 (US), EN ISO 11469 (EU), or GB/T 16288 (China). Always verify local requirements.
Why Regulations Vary
Mold marking regulations are driven by industry standards (automotive, medical) and regional laws (packaging). A mold designed for one market may not comply with another. This guide covers the major regulatory frameworks that affect date coding and recycling marks.
Date Code Regulations
| Industry | Standard | Requirement | Format |
|---|---|---|---|
| Automotive (Global) | IATF 16949 | Production date traceability | Year + Month (minimum) |
| Medical (US) | FDA 21 CFR 820 | Lot/batch traceability | Lot number or date code |
| Medical (EU) | MDR 2017/745 | UDI + production date | Unique Device Identification + date |
| Aerospace | AS9100 | Full production traceability | Date + lot + material batch |
| Consumer Products | Varies by market | Often voluntary | Year + month if specified by retailer |
Recycling Mark Regulations
| Region | Standard | Product Scope | Enforcement |
|---|---|---|---|
| United States | ASTM D7611 | Plastic containers (varies by state) | State attorneys general |
| European Union | EN ISO 11469 | Plastic products above minimum size | National market surveillance |
| China | GB/T 16288 | All plastic packaging | Quality inspection authorities |
| Japan | JIS K 6899-1 | Voluntary for most products | Industry self-regulation |
Key Compliance Actions
- Audit all active molds for marking compliance before shipping to new markets.
- Document marking specifications per mold in a traceable format.
- Train operators on date code update procedures for each exchange type.
Compliance Strategy for Export Molds
Mold designers serving multiple markets should follow these principles:
- Date codes: Use the most stringent standard. IATF 16949 (Year+Month) satisfies most automotive customers worldwide.
- Recycling marks: Use exchangeable recycle mark pins so the symbol can be swapped per market. See resin identification codes.
- Documentation: Maintain a marking specification sheet per mold that lists the required marks for each export destination.
