Methodology guide -- CN 7304 (seamless steel tube)

Seamless tube is high-value CBAM steel, dominated by Chinese supply (~450kt/yr). Production process (Mannesmann piercing) is energy-intensive, adding to upstream BF-BOF emissions.

Step 1 -- request route-specific verified data. Seamless tube emissions vary by mill: modern Chinese plants (Tianjin Pipe, Baosteel) report 1.9-2.2 t/t direct; older capacity reports 2.3-2.6 t/t.

Step 2 -- handle oil & gas grades carefully. OCTG (Oil Country Tubular Goods) often has API 5L or API 5CT certifications with stringent quality control. CBAM verification is independent of API certification -- request both.

Step 3 -- monitor strategic supply. Seamless tube supply is concentrated; CBAM cost differences between qualified suppliers can be material in long-term procurement decisions.

常见问题

What is CN 7304?
Tubes, pipes and hollow profiles, seamless, of iron (excl. cast iron) or steel. Used in oil & gas, power generation, structural applications.
How does seamless production differ from welded for CBAM?
Seamless tube production uses Mannesmann piercing or extrusion -- emissions intensive. Per-tonne emissions are typically 0.1-0.2 t CO2/t higher than welded tube of equivalent grade.
