WD vs. a 3PL for your FBA reserve inventory?

Same job — store bulk, feed FBA. The difference: Amazon's algorithm replenishes (AWD), or you do (3PL).

AWD wins on storage cost. A 3PL wins on control + bundled prep.

USPS quietly killed the cheap rate on light packages.

Most Amazon sellers avoid hazmat. Waitlist, paperwork, rules that change. The result: one of the quietest corners of FBA, with fewer Buy Box competitors and better margins. Here's what every approved hazmat seller actually knows. 🧵

The real cost of selling hazmat on FBA:
• Storage: 25-35% premium • Fulfillment: 5-10% surcharge per unit • Separate hazmat storage limits • SDS authoring (if needed): $200-500
The trade-off: less competition, better margins, more stable pricing.
