Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If for decorative/ornamental use
Ornamental stainless tubing has separate subheading regardless of forming method.
If imported as vehicle exhaust parts
Assembled exhaust system components classify under Chapter 87 auto parts.
If hot-finished rather than cold-formed
Non-cold-reduced stainless tubes fall outside this specific cold-drawn subheading.
