HS Code for Seamless stainless steel tubes

HS code 7304.49 applies to seamless tubes, pipes, and hollow profiles of stainless steel that are not cold-drawn or cold-rolled. These are typically hot-finished products. The classification is determined first by the material (stainless steel, as defined by chromium content) and second by the manufacturing method (seamless). The exclusion of cold-finished products (which fall under 7304.41) means that 7304.49 covers tubes that have been hot-rolled, hot-drawn, or extruded and have not undergone subsequent cold-reduction processes to achieve tighter tolerances or smoother finishes. These tubes are widely used in industrial environments where corrosion resistance is paramount, such as in heat exchangers, chemical reactors, and food processing equipment. Under the Harmonized System, the distinction between hot-finished and cold-finished is a primary divider for steel products, as the additional processing for cold-finishing significantly alters the physical properties and value of the steel. Importers must ensure that the surface finish and dimensional tolerances described in the shipping documents align with hot-finished standards to justify the use of 7304.49. This code serves as the general category for stainless seamless tubes that do not meet the specific criteria for oil/gas line pipe or cold-finished precision tubing.

Products Included

• Hot-finished seamless stainless steel tubes
• Stainless steel hollow bars (hot-rolled)
• Industrial process piping (seamless stainless)
• Heat exchanger tubes (hot-finished)
• Corrosion-resistant structural stainless tubes

Common Misclassification

The most frequent misclassification is 7304.41, which is for cold-drawn or cold-rolled stainless steel tubes. If a tube has been cold-finished, it must be moved to 7304.41. Additionally, welded stainless tubes are classified under 7306.40, and line pipes for oil/gas are classified under 7304.11.

FAQ

What is the HS code for 7304.49?

The HS code 7304.49 is for seamless stainless steel tubes, pipes, and hollow profiles that are not cold-drawn or cold-rolled.

What is the difference between 7304.41 and 7304.49?

7304.41 is for cold-finished (cold-drawn or cold-rolled) tubes, while 7304.49 is for hot-finished tubes.
