Error 100019 — Hazardous materials disclosure required

Your product is in a category that requires explicit hazardous materials disclosure — even if it doesn't actually contain hazmat. You must complete the questionnaire.

Amazon requires hazmat questionnaire for categories where hazmat is common — supplements, batteries, chemicals, aerosols. Even non-hazmat items in those categories need to disclose.

1. Open Seller Central → Inventory → Hazardous Goods Identification → New Submission.
2. Complete the questionnaire — answer truthfully about battery type, chemicals, gas, etc.
3. If non-hazmat, the listing unblocks within 24 hours.
4. If hazmat, you'll need an SDS upload as well.

• Skipping the questionnaire — listing stays blocked
• Under-declaring hazmat — leads to FBA rejection later
