Online Sellers’ Bill of Rights Would Rewrite Marketplace Enforcement

E-Commerce

The newly introduced Online Sellers’ Bill of Rights Act of 2026 would create federal standards for how dominant online marketplaces investigate and penalize third-party sellers. The proposal does not stop platforms from acting against counterfeit, fraudulent, or unsafe products; it focuses on making enforcement more transparent and time-bound.

Under H.R. 9799, marketplaces would generally have to give sellers individualized notice of an alleged violation, identify the policy and evidence involved, explain the proposed penalty, and provide a meaningful appeal process. The bill also proposes a 30-day limit on inventory and payment holds unless a platform can substantiate that goods or transactions are unlawful.

Material changes to product eligibility, listing restrictions, compliance requirements, commissions, or fees would require at least 30 days’ written notice. If a newly restricted product is already inside a platform’s fulfillment network, the seller would receive time to sell through the inventory or return it without bearing the removal cost.

The bill was introduced on July 21 and remains a proposal under consideration, not current law. Its definition of a covered “dominant platform” is not tied to a clear revenue, transaction, or market-share threshold, leaving an important scope question unresolved.

What sellers and operators should do

Sellers should not change compliance procedures as though the bill has passed. Instead, use the proposal as a prompt to improve enforcement readiness:

  • Keep invoices, authenticity records, safety certificates, and listing-change histories organized by SKU.
  • Export account-health notices, case correspondence, payment statements, and inventory reports on a regular schedule.
  • Track the date, policy citation, evidence requested, funds affected, inventory affected, and response time for every enforcement case.
  • Model cash-flow exposure to a 30-day hold and identify SKUs whose removal or return costs would create the largest operational risk.
  • Continue diversifying sales channels; even stronger appeal rights would not eliminate the disruption caused by a suspension.

For marketplaces, the operational signal is equally clear: enforcement systems may need case-specific notices, auditable evidence, defined resolution timelines, and human-review paths rather than generic responses. Sellers that already maintain a clean evidence trail will be better positioned whether the bill advances, changes, or stalls.
