Key takeaways
- The strongest red flags are structural: recently formed counterparties, serial company start-ups and closures, and routing through tax havens.
- Mismatch between documents (invoice, bill of lading, delivery order, customs record) is where most frauds surface.
- Pattern beats instance: an assured who never claims shortages from customs but always from insurers is a pattern to investigate.

Know the counterparty
- Seller and buyer verification. Verify the identity and background of first-time and second-time sellers and buyers. Look for histories of fraud or unusual practices.
- A company formed recently, or a director with a history of serially opening and closing companies in short spans, especially in tax havens such as Hong Kong, Singapore, Dubai or Mauritius, is a major red flag.
- Customer due diligence. Use a proper process and external background checks to verify identity and reputation of every party.
Follow the money and the duty
- Invoice scrutiny. Compare invoice value with market rates and history. Look for over- and under-invoicing.
- Multiple invoices. Investigate cases where one invoice is issued for remittance and another for duties.
- Duty drawback. Verify claims against customs records.
- Duty evasion. Watch for repeated under-declaration, and verify declared value against customs. Where shortages and non-deliveries are never claimed from customs, cargo is cleared in full on the bill of entry, yet shortages are claimed from the insurer, check whether it is convenience or a pattern.
- Tax haven intermediaries. Scrutinise merchants or indentors based in tax havens. With some African and South-East Asian destinations, exporters use such traders for hawala-style settlement: India to the haven at value X, the haven to the end destination at value Y, and the difference (Y − X) is where the illusion happens. These are hard to track until a full fraud case surfaces.
Check the documents and the cargo
- Bills of lading and delivery orders. Verify authenticity and that they match description and quantity. Confirm delivery orders and telex releases, and stay in regular touch with bankers.
- Cargo inspection. Inspect or audit physically where needed, and confirm the cargo matches the paperwork.
- Documentation review. Review contracts, bills of lading, invoices and certificates of origin for inconsistencies among them.
- Data analysis. Use analytics to flag unusual patterns, changing cargo values and shifting routes.
- Industry benchmarking. Compare claims and cargo values with benchmarks to surface discrepancies.
Build the organisation around it
- Whistleblower mechanism for employees, clients and stakeholders, with confidentiality.
- Training and awareness on common fraud schemes.
- Regular internal and external audits of claims and transactions.
- Collaboration with law enforcement, customs and industry associations.
- Legal action when fraud is proven: report to authorities, pursue civil remedies or end the relationship.
- Fraud specialists with marine cargo experience, consulted where the case justifies it.
- An adaptive approach. Fraudsters change tactics, so detection rules must change too.
- Reporting suspected fraud to the relevant authorities and regulators.
A note on method
The most effective approach pairs data analytics with field experience in claims and inspection. Analytics finds the anomaly; a person with cargo experience judges whether it is fraud, bad luck or a clerical error.
Red flags are prompts for inquiry, not proof of wrongdoing.
