Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If merely galvanized
Zinc coatings for offshore use classify separately from stainless cladding.
If fabricated drilling rig components
Platform structural assemblies classify under oilfield equipment.
If high-strength steel base
Offshore grades meeting high-strength steel note (a) use alloy provisions.

Import Tips & Compliance
• Include DNV-GL or ABS certification for offshore structural applications
• Test cladding for PREN value (>35 for duplex stainless) confirming corrosion resistance
• Declare Charpy impact values for both base and cladding at platform temperatures
