| FDA Registration | US market compliance | Essential for US sales |

| NASC Quality Seal | Industry-specific animal supplement standards | Highly recommended |

| ISO 22000 / FSSC 22000 | Food safety management | International credibility |

| Organic / Non-GMO | Ingredient sourcing standards | Market differentiation |

How to Verify:

1. Request current certificates (not expired)

2. Check certification body databases

3. Review inspection history

4. Ask for audit reports

Red Flags:
