A353 Grade Ni-Ni Alloy Steel Plate for Low-Temperature Service from China
ASTM A353 is a 9% nickel alloy steel plate supplied in widths exceeding 600 mm, designed for cryogenic service such as LNG storage tanks. The high nickel content (approximately 9%) makes it an alloy steel, but it does not qualify as stainless steel because its chromium content is below 10.5%. As a hot-rolled, flat-rolled product not further worked, it is classified under tariff item 7225.99.00 as 'Other' alloy steel.

Import Tips
• Provide documentation confirming the nickel content (around 9%) and chromium content below 10.5% to distinguish it from stainless steel
• The plate must be over 600 mm wide to qualify for heading 72.25; if narrower, classification changes
• Check for end-use or remission programs that may apply to energy-sector equipment
