Switch bills of lading attract trouble fast. Use this checklist to stop bad requests at the door. These ten red flags cover the patterns that lead to misdelivery, L/C disputes, and sanctions exposure. If any flag appears, do not proceed until the risk is cleared or the request is rejected.
Red Flag 1: Requestor Cannot Produce All Originals
Why to reject: Multiple bills in circulation = misdelivery risk. Carrier cannot safely cancel if copies exist elsewhere.
LSP Action: Ask for all originals. If unable to produce, deny request.
Red Flag 2: Request to Change Loading Port
Why to reject: Impossible to accomplish. Cargo was physically loaded at specific port. Cannot rewrite history. Indicates fraud intent.
Example: “Change loading port from Shanghai to Singapore” = Fraud signal for sanctions evasion or tariff misclassification.
LSP Action: REJECT immediately.
Red Flag 3: Request to Change Loading Date
Why to reject: Signals L/C fraud or sanctions evasion. Shipper wants to make shipment appear earlier/later than actual.
Example: Original loaded 2025-10-01, requested switch shows 2025-09-15 (earlier) = L/C fraud signal (meets L/C timeline by ante-dating).
LSP Action: REJECT immediately.
Red Flag 4: Request to Change Vessel or Voyage
Why to reject: Core contract terms. Cannot change what ship carried the cargo.
LSP Action: REJECT immediately.
Red Flag 5: Request to Materially Change Cargo Description
Why to reject: Different product = fraud/misrepresentation. Used for sanctions evasion (hiding true product nature) or tariff evasion (showing lower-tariff product).
Examples to REJECT: Original: “Electronic circuit boards” Switch: “Plastic components” (different product = REJECT). Original: “Telecommunications equipment” Switch: “Consumer electronics” (hiding controlled item nature = REJECT). Original: “Dual-use machinery” Switch: “General machinery” (evasion of export controls = REJECT).
OK to Approve: Original: “Shirts” Switch: “Cotton T-Shirts” (clarification, same product = OK). Original: “Metals” Switch: “Aluminum ingots” (detail added, same substance = OK).
LSP Action: Review cargo description change closely with compliance counsel if any doubt.
Red Flag 6: Ante-dated or Post-dated BL Requested
Why to reject: Documentary fraud signal. Used for L/C timing fraud.
LSP Action: REJECT immediately. Switch BL issue date must be LATER than original (never earlier). LOIs that aim to validate false dates are generally unenforceable.
Red Flag 7: Shipper from Sanctioned Country/Entity
Why to reject: Export control violation risk. Sanctions evasion.
LSP Action: Run shipper/consignee through OFAC SDN, EU sanctions lists, UN lists. If matches: REJECT and report to compliance officer. Document rejection reason.
Red Flag 8: Shipper is Unknown Intermediary (No Trade History)
Why to reject: One-time requestor with no history = fraud pattern. LSP has no ability to verify legitimacy.
LSP Action: Check shipper business registration. Request references (other carriers/forwarders they’ve worked with). Ask for detailed business rationale. If insufficient documentation: REJECT.
Red Flag 9: Routing Through Known Sanctions Evasion Hubs (Without Clear Justification)
Why to reject: High-risk transshipment pattern. Dubai for Iran goods, Singapore for North Korea, Mauritius for sanctioned finance.
Example to REJECT: Shipper: Iran entity (OFAC-listed). Routing: Shanghai Dubai Consignee: UAE intermediary. Consignee: Cannot be identified. Commercial invoice: Vague (shows “merchandise”). Pattern screams sanctions evasion = REJECT.
LSP Action: If routing through high-risk hub, ask for detailed commercial justification. Verify buyer/consignee at destination is legitimate (not shell company). Confirm buyer can legally import (not in sanctioned country). If justification weak: REJECT.
Red Flag 10: LOI Not Provided or Not Bank Co-Signed
Why to reject: Uninsured risk for carrier and LSP. If fraud discovered, no recourse.
LSP Action: Do NOT issue switch without proper LOI. Period.
Turn red flags into a repeatable intake check
Readers of this checklist usually face one of three problems: intake decisions take too long, evidence gets scattered, or status is unclear for customers. TRADLINX Ocean Visibility gives your team one place to see carrier events, add accountable notes, attach proofs, and share live status when a decision is made.
What to do when a flag appears
- Unknown intermediary: add a note with KYC results and the reviewer’s name and time; attach the business registration and references to the BL record.
- Destination change requested: note that the case will follow Change of Destination, not a switch; track the COD milestones on the same shipment.
- Late paperwork: record the decision to use telex or sea waybill; attach the carrier confirmation; watch for release in the live timeline.
- Cargo description change: add a comparison note listing the original description, HS code if relevant, and the requested wording; attach compliance approval or reject with reason.
- LOI gaps: attach the LOI file; add a note with how the bank participation was verified and by whom.
Why this matters for your team
- Ops leads: faster intake decisions because status, checks, and carrier replies live with the shipment.
- Compliance: a clear sequence of notes and files that supports audits and dispute resolution.
- Customer teams: share a live view link so clients see status without ticket back-and-forth.
Next step: use TRADLINX Ocean Visibility to keep the red-flag note, supporting files, and live events on one timeline, then export the history and save the linked files with the job record.
