Alternative Classifications

This product could be classified differently depending on its characteristics or intended use.

7307.23.00Higher: 40% vs 35%

If imported as flanged stainless fittings

Tubing sections with machined flanges for connection classify under 7307 as pipe fittings, not plain OCTG tubing.

7222.40Lower: 10% vs 35%

If stainless steel bars machined into tubing

Hollow bars or semi-finished shapes used to make tubing fall under Chapter 72 as semi-products, not finished tubes.

7304.29.10.10Same rate: 35%

If drill pipe of stainless steel without couplings

Uncoupled stainless drill pipe (thicker walls) uses 7304.29, distinct from thinner-walled coupled tubing in 7306.

Import Tips & Compliance

Include hydrostatic test records (min 80% of minimum yield strength) as standard OCTG proof

Label bundles with heat numbers traceable to MTCs; missing traceability triggers FDA-equivalent CBP holds

For re-import after testing, file CF-7501 with proper 9801/9802 annotations to avoid double duties
