If you’re reading this, chances are you received an Amazon Prop 65 compliance warning—or worse, your listing was taken down.
You’re not alone.
Thousands of sellers are being caught off guard by California’s Proposition 65 labeling laws, and many don’t realize until it’s too late that Amazon holds sellers responsible for compliance—even if you’re not located in California.
I’ve spent the last several years studying, advising, and designing solutions for brands, prep centers, and sellers just like you. I created this guide not only to help you fix your Amazon listing quickly, but to also protect your business permanently with the most durable, legally compliant solution available: sew-on Prop 65 labels.
🔥 Why Is This So Serious?
Under Prop 65 law, if your product contains even trace amounts of regulated chemicals like lead, cadmium, DEHP, nickel, or others—and is sold or shipped into California—you are required to provide a clear and reasonable warning.
Failure to do so can lead to fines of up to $2,500 per violation per day. And yes—each unit sold without the warning counts.
Amazon knows this, and that’s why they’ll issue a compliance takedown, suppress your listing, or even suspend your account. This isn’t just a warning. It’s a legal issue.
🚨 What Triggers the Warning?
Most sellers I’ve worked with had no idea their products contained these chemicals—because they weren’t the manufacturer.
Here are the most common causes:
- Imported apparel or fabrics
- Synthetic dyes, inks, or coatings
- Plastic components or hardware
- Unlabeled packaging from prep centers or suppliers
Even if your supplier didn’t provide you with a warning, you’re still legally liable. So how do you fix it?
✅ Step-by-Step: How to Fix Your Amazon Listing Now
1. Add the Legal Warning to Your Amazon Listing
You need to add this warning in your bullet points, product description, or legal disclaimer:
⚠️ WARNING: This product can expose you to chemicals including Di(2-ethylhexyl)phthalate (DEHP), lead, cadmium, and nickel, which are known to the State of California to cause cancer and birth defects or other reproductive harm. For more information, visit www.P65Warnings.ca.gov
If you don’t know the specific chemicals, use this generic version:
⚠️ WARNING: Cancer and Reproductive Harm — www.P65Warnings.ca.gov
2. Add a Physical Warning to Your Product
This is where most sellers get it wrong.
💡 Amazon requires the warning to be seen before or at the time of purchase
But Prop 65 requires the warning to be visible on the product itself—for every item shipped into California.
That’s why I created professional-grade sew-on Prop 65 labels for apparel, textiles, and fabric-based goods. These are woven, washable, and designed to last through the product’s entire life cycle—not peel off like stickers.
🧵 Why Sew-On Labels Are the Best Fix
- ✅ Durable & permanent — they won’t fall off like stickers
- ✅ Washable — survives heat, laundering, folding, and packing
- ✅ Visibly compliant — protects you legally and builds trust with customers
- ✅ Pre-printed & pre-sized — no design work or guesswork required
- ✅ Bulk priced — available in 100, 500, and 1000 unit packs
- ✅ FBA & prep-center ready — ideal for relabeling or bulk processing
If you’re reading this, you don’t need a long-term branding solution.
You need a fast, legal fix to keep your listing live and your risk low.
