Cold-Drawn 17-4 PH Stainless Steel Capillary Tube
Ultra-precise seamless cold-drawn capillary tubing from 17-4 precipitation hardening stainless alloy steel, circular cross-section for medical instruments. HTS 7304.51.50 covers this as 'other' cold-rolled seamless tubes of alloy steel under 16mm dimension. Tight tolerances enable use in catheters and sensors.

This product may fall under a more specific subheading:
Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If not hollow profile but bar stock
Solid bars of stainless steel fall under Chapter 72, not hollow tubes.
If suitable for pressure vessels
Tubes designed for high-pressure service classify under specific pressure vessel subheading.
If processed into finished medical needle tubing
Further worked tubes for medical instruments shift to Chapter 90.

The Tariff Assistant works through the GRI rules on your specific product to reach the right HTS code — and can price the duty on it in the same conversation.
Import Tips & Compliance
• Provide surface finish specs (e.g
• Ra <0.8μm) to distinguish from hot-finished tubes
• Bulk vs retail packaging; retail sets may invoke GRI 3 for composite goods
