Automotive Seamless Steel Brake Lines
Seamless nonalloy steel tubes with thin walls (<4 mm) for hydraulic brake systems in vehicles. Classified in HTS 7304.90.50.00 as seamless pipes of iron/nonalloy steel, not as vehicle parts.
Import Duty Rates by Country of Origin
Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If when imported as original vehicle equipment parts
Brake line assemblies for specific vehicles classify under Chapter 87 as motor vehicle parts.
If double-walled or welded versions
Welded brake lines common in automotive use fall under welded pipe provisions.
If thicker walls for heavy-duty trucks
Wall ≥4mm shifts to separate subheading within 7304.90.

Import Tips & Compliance
• Certify compliance with SAE or ISO standards for automotive use without triggering parts classification
• Ship in bulk coils, not pre-bent shapes, to maintain tube status vs. finished assemblies
• Document wall thickness rigorously to avoid confusion with heavier vehicle frame tubes
