HS Code for Boiler Pipe 190.5–285.8mm, Thin Wall
TL;DR: Thin-wall boiler pipes 190.5–285.8mm typically use HS code 7304.19 for seamless steel types in industrial applications. Accurate classification avoids customs issues; key traits include heat efficiency and reduced weight. Updated for 2025 regulations.
What Is the HS Code for Thin-Wall Boiler Pipes 190.5–285.8mm?
HS codes classify goods for global trade. For thin-wall boiler pipes in the 190.5–285.8mm diameter range, the primary code is 7304.19 under Chapter 73.
These seamless steel pipes suit high-pressure boilers in power plants and factories.
- Chapter 73: Iron or steel articles
- Heading 7304: Seamless tubes/pipes
- Subheading 7304.19: Other, excluding cast iron
Confirm with local customs for 2025 updates.
Key Specifications of 190.5–285.8mm Boiler Pipes
Thin-wall designs optimize industrial boiler performance. Diameters from 190.5mm to 285.8mm handle large-scale heating systems.
- Wall thickness: Typically 5-10mm for thin-wall
- Material: Carbon or alloy steel (ASTM A106/A179)
- Pressure rating: Up to 100 bar
- Applications: Steam boilers, heat exchangers
- Standards: ASME SA192 for boilers
These specs ensure durability under heat stress.
How to Classify Thin-Wall Boiler Pipe HS Code in 2025
Follow WCO guidelines for precise HS code assignment. No major WCO revisions until 2027, but 2025 brings national tariff tweaks in EU/Asia.
- Identify if seamless (7304) vs. welded (7306)
- Check diameter: 190.5–285.8mm fits 7304.19
- Verify thin-wall via technical datasheet
- Consult HS explanatory notes
- Use binding tariff info from customs
2025 case study: A Chinese exporter reclassified to 7304.19, saving 2.5% duties to EU.

Benefits of Thin-Wall Boiler Pipes 190.5–285.8mm
These pipes excel in efficiency for industrial use.
- Superior heat transfer: Thinner walls boost conductivity
- Weight savings: 20-30% lighter than thick-wall
- Cost reduction: Less material lowers production expenses
- Easy installation: Flexible for complex boiler designs
- High corrosion resistance: Ideal for steam environments
Common Challenges with Boiler Pipe HS Classification
Misclassification risks delays and fines. Overlaps confuse welded vs. seamless pipes.
- National HS variations post-2025
- Technical spec ambiguities
- Anti-dumping duties on steel pipes
- Documentation errors
- Brexit-style regional changes
Solution: Use expert tools for verification.
2025 HS Code Updates for Steel Boiler Pipes
Fresh regulations impact thin-wall imports. EU's Carbon Border Adjustment (CBAM) from 2025 adds scrutiny to HS 73 codes.
- US: New steel tariffs on specific alloys
- China: Export quotas tightened
- WCO: Enhanced environmental subheadings
- India: 10% safeguard duties
Case study: 2025 power plant shipment from Asia to US avoided 25% penalties via correct 7304.19 use.
FAQ: HS Code for Thin-Wall Boiler Pipes
