Do I have to test every product for Prop 65?

No, but if you do not test, you must prominently display the "Safe Harbor" warning label indicating the product contains chemicals known to the State of California to cause cancer or reproductive harm. To avoid the ugly warning label, you must pay for lab testing (typically $100-$300 per material) to prove your goods do not exceed safe harbor levels for heavy metals and phthalates.

California Proposition 65 Risk Modeling

Prop 65 is enforced aggressively by private "bounty hunter" law firms in California. If you sell an imported tote bag into California that contains excess phthalates without a warning label, these law firms will sue you.

Settling a Prop 65 lawsuit generally costs $30,000 to $80,000. It is drastically cheaper to implement a $300 lab-testing protocol in China or simply apply the warning sticker than to face a lawsuit.

Tips for China Importers

Identify compliance requirements before sourcing, not after. Discovering that your product needs a $30,000 FDA clearance after you've ordered 5,000 units is a business-ending scenario. Research first.
Use only accredited labs. Test reports from SGS, Intertek, Bureau Veritas, or TÜV are accepted by retailers, Amazon, and customs. Supplier-provided "test reports" from unknown labs are worthless for compliance purposes.
Verify CE/FCC was tested on production units, not prototypes. Certifications obtained on pre-production samples are technically valid only for that sample. If production materials differ, retesting is required.
Check for anti-dumping duties before importing. Anti-dumping and countervailing duty orders cover hundreds of Chinese product categories. These are separate from HTS duties and can be 20–200%+ of value.
Keep all compliance documents for at least 5 years. Amazon, major retailers, and CBP may request CPC certificates, test reports, or labeling documentation at any time. Losing records can cost you your account.
