Import Tips

Provide BET surface area analysis confirming high-support characteristics essential for 3815 classification

Declare nickel loading percentage accurately; excessive metal may trigger 3815.11 base metal heading

Include reaction test data demonstrating methanation activity to distinguish from mere chemical compounds
