Shipper Load and Count vs Carrier Load on a Rail BoL (2026)

Almost every modern rail carload move is shipper-loaded. The shipper drives the car to its facility (or a transload), loads it, seals it, and tenders it to the railroad. The piece count on the BoL is what the shipper says — the railroad didn't open the car to verify. When the consignee opens the car at destination and finds 95 widgets where the BoL says 100, who's on the hook? It depends on whether the BoL says SLC.

SLC: Said-to-Contain Limitation

"Shipper Load and Count" (also rendered as "SLC," "Shipper's Load and Count," or "SL&C") on the BoL signals that:

• The shipper loaded the car at the shipper's facility (or its designated transload/loading point)
• The shipper sealed the car
• The railroad accepted the car based on the shipper's count of contents but did not independently verify

Legal effect: the BoL is a receipt only as to weight and external condition. The piece count is "said to contain" — the railroad's liability for shortage is limited if the seals are intact at delivery. If the consignee finds fewer pieces than the BoL says, the burden shifts to the shipper to show the shortage occurred in transit (which is hard when seals are intact and the consignee has no way to prove what was actually loaded).

Carrier Load: Full Piece-Count Liability

"Carrier Load" (or absence of SLC notation) means the railroad participated in loading — typically at the railroad's own loading facility or via a railroad-managed loader. The railroad verified the piece count.

Legal effect: the BoL piece count is binding on the carrier. Under Carmack (49 USC §11706), the railroad is liable for any shortage between origin and destination unless it can show one of the §11706(c) defenses (act of God, public enemy, act of shipper, public authority, inherent vice).

The Practical Frequency

SLC dominates modern rail because almost all loading happens at shipper/transload facilities without railroad personnel present:

• Bulk commodities (grain, aggregates, plastic resin) — SLC nearly always
• Boxcar paper, packaged consumer goods — SLC nearly always
• Hazmat tank cars — SLC unless the railroad has on-site inspectors
• Lumber and forest products — SLC, often with shipper-supplied dunnage

Carrier Load shows up in specific scenarios:

• Less-than-carload (LCL) freight moving through a railroad freight house (historical / rare modern)
• Some intermodal terminal operations where the railroad/terminal stuffs the container
• Government Bills of Lading where federal inspector witnesses loading

What This Means for Shortage Claims

Under Carmack, the shipper makes a prima facie case for shortage liability by showing:

1. Goods delivered to the carrier in a particular quantity / condition
2. Goods received by the consignee in lesser quantity / different condition
3. Resulting damages

With Carrier Load, the BoL piece count establishes element (1). With SLC, the BoL doesn't establish element (1) because the railroad didn't verify the count. The shipper has to come with independent evidence of what was loaded — loading logs, weights, photos, automated counter records.

How to Render on the BoL

The convention is to add "SHIPPER'S LOAD AND COUNT" or "SLC" as a notation on the commodity line or in the special instructions block. Sometimes also rendered as "SAID TO CONTAIN" or "STC."

The free Rail BoL Builder exposes an "Shipper Load and Count" checkbox that adds the notation to each commodity line. Default is on (because most moves are SLC); toggle off if the railroad verified the load.

Seal Integrity and SLC Defense

The railroad's SLC defense depends heavily on seal integrity. If the car arrives with seals intact at the same numbers as listed on the BoL, the railroad has a strong defense against in-transit shortage allegations. If seals were broken or replaced, the SLC defense weakens.

Practical implications:

• Record seal numbers on the BoL accurately at origin
• Consignee verifies seal numbers + intactness before opening
• Photo-document seals if there's any anomaly
• Document any seal break in transit (railroad inspection events, government boarding)

Hazmat SLC

For hazmat, SLC is the norm because shippers load and seal at their facilities under §172.704-trained employee supervision. The §172.204 certification on the BoL covers the loading and packaging accuracy. SLC doesn't relieve the shipper of §172.204 liability — the shipper certified the load when they signed.

Best Practices

1. Match BoL piece count to actual loaded count. SLC isn't a license to under-count.
2. Record loading evidence (timestamps, weights, scanner records, photos).
3. Verify and record seal numbers at origin.
4. Have consignee verify seals + count at delivery before signing the delivery receipt.
5. If shortage discovered, document seal status immediately and file Carmack claim within the 9-month window.
