Heading 7306

Other tubes, pipes and hollow profiles (for example, open seamed or welded, riveted or similarly closed), of iron or steel

68 declarable lines

Heading 7306 covers welded and similarly closed tubes, pipes and hollow profiles of iron or steel, other than seamless tubes of heading 7304 and very large circular pipe of heading 7305. It is split first by use (line pipe, casing and tubing for oil or gas drilling, then other welded pipe), then by steel type, cross section, wall thickness and outside diameter. Every declarable line in this heading carries a general (MFN) rate of Free.

Products in this heading

  • Welded stainless steel line pipe for oil or gas pipelines
  • Welded iron casing threaded or coupled for oil or gas drilling
  • Galvanized welded round steel pipe imported with couplings
  • Welded steel tube suitable for boilers, heat exchangers and condensers
  • Square or rectangular welded steel tube with wall thickness under 4 mm

How to choose the right subheading

  • Steel type: stainless steel, iron or nonalloy steel, or other alloy steel
  • End use: line pipe, casing and tubing for oil or gas drilling, or other pipe
  • Cross section: circular or noncircular, and square or rectangular if noncircular
  • Wall thickness: under 1.65 mm or 1.65 mm and over for circular pipe, and under or over 4 mm for noncircular
  • Outside diameter brackets, particularly 114.3 mm, 50.8 mm and 406.4 mm

Often confused with

  • Seamless steel pipe

    7306 covers welded and similarly closed pipe; seamless pipe is classified in 7304.

    Heading 7304
  • Welded circular pipe with outside diameter over 406.4 mm

    Very large circular welded pipe is specifically covered by heading 7305.

    Heading 7305
  • Steel pipe fittings such as elbows and couplings

    Fittings are separate from the tube or pipe itself.

    Heading 7307
  • Welded steel angles, shapes and sections, or sheet piling

    Open sections and piling are not hollow profiles.

    Heading 7301
  • Welded steel tube cut and prepared for use in a structure

    Tubes prepared for structural use fall in 7308.

Frequently asked questions

What is the HTS code for welded stainless steel pipe with a wall thickness under 1.65 mm?

Use 7306.40.10.90 for other welded circular stainless steel pipe with a wall thickness under 1.65 mm. The general (MFN) rate is Free.

What is the duty on welded square steel tube with a wall thickness under 4 mm?

Square or rectangular welded tube of iron or nonalloy steel with a wall thickness under 4 mm is classified in 7306.61.50.00. The general (MFN) rate is Free.

How do I classify welded carbon steel pipe imported with couplings?

Galvanized welded circular iron or nonalloy steel pipe with a wall thickness of 1.65 mm or more and an outside diameter not exceeding 114.3 mm, imported with coupling, goes in 7306.30.50.26 or 7306.30.50.27 depending on diameter. Both carry a general (MFN) rate of Free.
