It is not legally mandatory — but it is strongly recommended, and for ceramics especially, I would call it near-essential.
Here's the reality of carrier liability that most shippers don't fully appreciate:
Carrier liability under international law is extremely limited. Ocean carriers operating under the Hague-Visby Rules (which govern most international ocean shipments) are liable for a maximum of approximately SDR 2 per kg or SDR 666.67 per package, whichever is higher. At current SDR exchange rates, that's roughly USD 2.70/kg or USD 900 per carton — far less than the actual value of most cargo.
For your 10,000 USD ceramic shipment weighing (say) 500 kg:
- Carrier liability: ~USD 1,350 (at SDR 2/kg)
- Your actual loss: USD 10,000
- Gap: USD 8,650 — your problem, not the carrier's
And carrier liability is further reduced or eliminated if the damage was caused by:
- Inherent vice of the goods (ceramics are fragile — carriers will argue this)
- Inadequate packing
- Acts of God
- Perils of the sea
For ceramics specifically: Breakage in transit is extremely common in LCL due to cargo handling at the CFS. I have seen 20–30% breakage rates on poorly packed ceramics. Even with good packaging, 5–10% loss is not unusual.
Cost of cargo insurance: For USD 10,000 of ceramics, All Risk cargo insurance typically costs USD 50–100 for a single shipment. That's 0.5–1% of cargo value. For six-sigma protection on fragile goods worth $10,000, that's an obvious yes.
Your forwarder is right to recommend it. It's not just commission — claims happen.
