BLACKSTONE MATERIALS LLC holds active federal broker authority (946313). Whether a surety bond is on file, the bond amount versus the $75,000 BMC-84 floor, and any authority revocations are shown in the broker-vetting section on this page — check them before you haul, since a bonded, active broker is the baseline signal you can expect to get paid.
Operating authority is verified against the live public registry and refreshed daily. Current status: ACTIVE. "active" means the carrier is authorized to operate; "inactive" or "out-of-service" indicates the carrier should not be hauling.
Liability and cargo insurance status is drawn from the latest filings on record. Current status: active. We mark a carrier "lapsed" when the most recent cancellation date is in the past with no superseding policy.
