15CrMo Alloy Steel Pressure Vessel Sheet
> 15CrMo is a low-alloy chromium-molybdenum steel, flat-rolled into sheets for boiler and pressure vessel applications. With a width exceeding 600 mm, it meets the definition of flat-rolled products of other alloy steel. It does not match the specific subheadings for heat-resisting or electrical steels, so it falls under this residual "Other" item.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If the sheets are of silicon-electrical steel
Silicon-electrical steel is a specific alloy steel defined in Subheading Note 1(c), which is classified separately.
If the sheets are hot-rolled and not further worked than clad
Hot-rolled alloy steel flat products, not clad, plated or coated, fall under a different subheading.

Import Tips & Compliance
• > Ensure the steel meets the definition of "other alloy steel" per Chapter 72 Note 1(f) — verify chromium and molybdenum content
• Provide a mill test certificate to the CBSA to confirm composition and width
• Check if the goods qualify for preferential tariff treatment under a free trade agreement by declaring the origin code on the import document

A204 Grade C Molybdenum Alloy Steel Plate
> A204 Grade C is a molybdenum alloy steel plate with 0.5% molybdenum, supplied flat-rolled with a width of 700 mm and thickness of 40 mm. It is used for pressure vessels. This product is classified as other alloy steel, not stainless or electrical, and falls under the "Other" item.
A302 Grade A Manganese-Molybdenum Alloy Steel Plate
ASTM A302 Grade A is a normalized manganese-molybdenum alloy steel plate supplied in widths exceeding 600 mm, primarily used for pressure vessel fabrication. Its molybdenum content of 0.45% to 0.65% by weight classifies it as other alloy steel under heading 72.25, as it does not meet the definitions for stainless, tool, or silicon-electrical steel. The product is hot-rolled and not further worked, falling under tariff item 7225.99.00 as 'Other' flat-rolled alloy steel.
A353 Grade Ni-Ni Alloy Steel Plate for Low-Temperature Service
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.
A387 Grade 11 Heat-Resistant Alloy Steel Plate
ASTM A387 Grade 11 is a chromium-molybdenum alloy steel plate with a width exceeding 600 mm, used for elevated-temperature service in refinery and pressure vessel applications. Its chromium content of 1% to 1.5% by weight qualifies it as other alloy steel, but it does not meet the 10.5% chromium threshold for stainless steel. The product is hot-rolled and not further worked, placing it under tariff item 7225.99.00 as 'Other' flat-rolled alloy steel.
A514 Grade B High-Yield Strength Alloy Steel Plate
ASTM A514 Grade B is a quenched and tempered high-yield-strength alloy steel plate, over 600 mm wide, used for structural applications requiring high strength-to-weight ratios. Its alloying elements, including chromium, molybdenum, and boron, make it an other alloy steel, but it does not meet the stainless steel definition. As a hot-rolled flat product not further worked, it is classified under tariff item 7225.99.00 as 'Other'.
A516 Grade 70 Pressure Vessel Steel Plate
ASTM A516 Grade 70 is a flat-rolled alloy steel plate with a width exceeding 600 mm, used for pressure vessels and boilers. Although often considered carbon steel, it contains alloying elements such as manganese and silicon that may push it into the 'other alloy steel' category if thresholds are met. As a hot-rolled product not further worked, it is classified under tariff item 7225.99.00 as 'Other'.
