This code covers seamless tubes and pipes of iron or steel specifically used as casing in oil or gas drilling, categorized by dimensions and wall thickness. Use this code when importing these specialized drilling components, noting they generally receive free duty under standard trade agreements or eligible preference programs as outlined in Chapter 73.

Detailed information for HTS Code 7304.29.41

This tariff code falls within Chapter 73, which covers articles of iron or steel. Specifically, 7304.29.41 covers seamless tubes and pipes of iron or steel used as casing in oil or gas drilling, made of other alloy steel. This code is further broken down by outside diameter and wall thickness, with subdivisions ranging from smaller diameter/thinner walled casing (7304.29.41.10 & 7304.29.41.20) to larger diameter/thicker walled options (7304.29.41.80), ensuring accurate classification based on these physical characteristics. When reporting, select the statistical suffix that corresponds to the specific dimensions (diameter and wall thickness) of the casing being imported.
