URGENT: FCC ID or SDoC? Get It Wrong and Risk Amazon Listing Removal

For Amazon US Sellers & North American Manufacturers: Attention! ⚠️

The FCC has two distinct certifications—choosing the wrong one is a costly mistake:

▫️ FCC ID:​ Required for products with Bluetooth, Wi-Fi, or 2.4G RF functionality.

▫️ FCC SDoC:​ Required for general electronic products (powered) with no RF transmission.

Failure to provide proper compliance documentation risks:

❌ Listing takedowns

❌ Customs detention

❌ Significant fines
