Import Duty Rates by Country of Origin
Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If welded iron/steel tubing (non-stainless) with couplings
Carbon steel versions use 7306.30; stainless requires minimum chromium per Chapter Note 1(g).
If parts of drilling rigs, not standalone tubing
Tubing imported as replacement parts for classified drilling machinery falls under 8431, not raw tubes.
If stainless casing without couplings
Uncoupled stainless casing (thicker wall) classifies under 7304.19, separate from coupled tubing.

Import Tips & Compliance
• Specify exact OD/ID/wall thickness in commercial invoice to match 7306 tubing definitions vs drill pipe
• Use thread protectors on couplings during ocean freight to prevent galling/cross-threading claims
• For Canadian imports, align with CSA Z245.1 standards alongside API for smoother cross-border clearance
