HS Code for Standard Welded Steel Pipe

TL;DR: Standard welded steel pipe uses HS code 7306 (diameter ≤406.4mm) or 7305 (larger) in 2025. Key changes include GCC 12-digit codes from Jan 1, US HTS mandatory Sep 1, and EU CN updates. Follow classification steps and tables for accurate tariff compliance.

What Is the HS Code for Standard Welded Steel Pipe?

HS codes classify traded goods worldwide. For standard welded steel pipe, the primary code falls under Chapter 73.

HS 7306 covers welded pipes, tubes, and profiles with circular cross-section ≤406.4mm.
HS 7305 applies to larger diameter welded steel pipes >406.4mm.
These 6-digit codes form the global standard, extended by countries.
Accurate use ensures tariff compliance 2025.

Primary HS Codes for Welded Steel Pipe in 2025

Standard welded steel pipe HS code centers on 7306 for most shipments.

Key subheadings distinguish by material and specs.

HS Code	Description	Key Features
7306.30	Welded circular iron/non-alloy steel pipes	≤406.4mm diameter, standard use
7306.40	Welded circular stainless steel pipes	Corrosion-resistant applications
7306.50	Welded circular other alloy steel pipes	Specialized strength needs
7305.11	Oil/gas line pipe, large diameter welded	>406.4mm, submerged arc welded
7305.31	Other large welded pipes	Longitudinally welded

2025 HS Code Changes Impacting Welded Steel Pipe

National updates in 2025 affect welded steel pipe classification.

GCC countries adopt 12-digit HS codes January 1, 2025, refining 7306 subheadings.
US mandates 10-digit HTS codes from September 1, 2025, ending de minimis for low-value imports.
EU Combined Nomenclature 2025 improves precision for alloy vs non-alloy steel pipes.
No WCO global revision until 2027; focus on regional HS code changes 2025.
These shifts demand updated tariff compliance 2025 checks.

Factors Determining Welded Steel Pipe HS Code

Six main factors guide HS classification for standard welded steel pipe.

Diameter: ≤406.4mm = 7306; >406.4mm = 7305.
Material: Iron/non-alloy (7306.30), stainless (7306.40), alloy (7306.50).
Wall thickness: Influences subheading precision.
Welding method: Longitudinal, submerged arc, etc.
End use: Oil/gas lines get specific codes like 7305.11.
Shape: Circular cross-section standard for these pipes.

How to Find HS Code for Welded Steel Pipe: 2025 Step-by-Step

Use this proven 5-step process for accurate classification.

Measure external diameter to select 7305 or 7306.
Identify steel composition via material certificates.
Determine primary end use from product specs.
Check welding technique from manufacturer details.
Apply 2025 regional extensions like GCC 12-digit codes.

Pro tip: Cross-reference with official WCO HS explanations for edge cases.
