One three-letter mistake in your shipping terms can trigger customs revaluations that dwarf your original shipment value
A German machinery manufacturer learned an expensive lesson about Incoterms in 2024. Their 17,000 EUR shipment to Turkey cleared customs without issue. Two weeks later, a 340,000 EUR bill arrived. The culprit? Three letters in their shipping contract: FOB instead of CIF.
This was not fraud. It was not a clerical error. It was a perfectly legal customs revaluation triggered by a mismatch between declared shipping terms and insurance coverage. And it is happening to European exporters every day.
What Actually Happened: The FOB-CIF Valuation Gap
The manufacturer used FOB (Free On Board) terms for a 17K EUR machinery shipment. Standard practice. The buyer handles insurance and freight from the port.
But their insurance policy covered 357K EUR - the full value of the machinery installation project, not just the shipment.
Customs officers in Turkey saw:
- Declared value (FOB): 17,000 EUR
- Insurance coverage: 357,000 EUR
- Valuation discrepancy: 2,000%
Under Turkish customs law, when insurance substantially exceeds declared value, they can revalue the shipment based on the insured amount. The result: 340K EUR in additional duties and penalties.
The manufacturer mistake was not the insurance. It was declaring FOB terms when the insurance value indicated CIF (Cost, Insurance, Freight) terms were more appropriate.
Why Customs Care About FOB vs CIF
Incoterms define when risk transfers from seller to buyer. But customs authorities use them for something else entirely: valuation.
FOB (Free On Board) means the seller responsibility ends when goods are loaded on the ship. The buyer arranges and pays for insurance and freight.
CIF (Cost, Insurance, Freight) means the seller includes insurance and freight costs in the price.
Customs officers do not care about your internal logistics. They care about declared value for duty calculation. When you declare FOB but insure for CIF-level amounts, they assume you are undervaluing to dodge duties.
According to a 2023 EU customs enforcement report:
- 23% of cross-border machinery shipments face valuation challenges
- Average revaluation adds 180-420% to original duty calculations
- Resolution takes 6-18 months
- Legal costs average 45K-120K EUR
The gap between shipping convenience and customs interpretation costs European exporters an estimated 2.3 billion EUR annually.
How to Avoid the 340K Surprise
Commercial invoice
Insurance certificate

Incoterm declaration
Key Takeaways
- FOB with high insurance coverage triggers customs revaluation red flags
- Customs use Incoterms for valuation, not just logistics
- 23% of cross-border shipments face valuation challenges
- Pre-clearance costs 2K; mistakes cost 340K
- Match your Incoterms to insurance reality before shipping
Conclusion
The German manufacturer eventually negotiated their 340K EUR customs bill down to 87K EUR after 14 months of legal proceedings. They now use CIF terms for all insured shipments and get advance valuation rulings for anything over 25K EUR.
Your shipping terms are not just logistics paperwork. They are customs declarations that can trigger revaluations costing 20x your shipment value. One contract review prevents years of legal battles.
