You are exporting stainless steel pipes overseas. The journey will take 30-60 days across the ocean. If the pipes are not packaged correctly, they will rust, get damaged, or shift during transit.

Proper export packaging for stainless steel pipes includes rust protection (VCI paper, oil coating), bundling and banding, end caps (to protect threads and bevels), and container loading with dunnage. Pipes must be secured to prevent movement during shipping. Packaging must also comply with ISPM-15 for wooden packaging materials.

I have shipped stainless steel pipes to many countries. A customer in the UAE required end caps on all pipes. A customer in the US required bundling and banding. Let me walk you through export packaging and shipping.

What is the HS code for 316l pipe?

The HS code for 316L stainless steel pipe depends on the type and dimensions. For seamless pipe, common codes are 7304.11 (for oil and gas) or 7304.49 (for other applications). For welded pipe, common codes are 7306.40 or 7306.61.

For most 316L seamless pipe, HS code 7304.49.10.00 is common for cold-drawn. For 316L welded pipe, HS code 7306.40.20.10 is common. Always verify with your customs broker as codes vary by country.

HS Code Classification for 316L Pipe

Let me provide the common HS codes for 316L stainless steel pipe.

Seamless 316L Pipe

HS Code	Description
7304.11	Seamless pipe for oil and gas (API standard)
7304.19	Other seamless pipe for oil and gas
7304.49	Other seamless pipe (general purpose)

Welded 316L Pipe

HS Code	Description
7306.40	Welded pipe, circular cross-section
7306.61	Welded pipe, square/rectangular cross-section

Important Notes

• Codes vary by country (add 3-4 digits for specific classification)
• Thickness and diameter affect sub-classification
• Always verify with your customs broker

My Experience
For a shipment of 316L seamless pipe (1-inch Sch 40S), we used HS code 7304.49. The customs clearance was smooth.

What is the price of 304 stainless steel pipe per kg?

304 stainless steel pipe costs approximately $3.50-5.00 per kg for welded pipe and $5.00-7.00 per kg for seamless pipe (2026 prices). The price varies by size, schedule, quantity, and market conditions.

For bulk orders (10+ tons), welded 304 pipe costs $3.50-4.00 per kg. For small orders (under 500 kg), the price can be $4.50-5.50 per kg. Seamless pipe costs 30-50% more than welded pipe.

304 Pipe Pricing Guide

Welded 304 Pipe (1-inch Sch 40S)

Quantity	Price per kg (USD)
Small (under 200 kg)	$4.50-5.50
Medium (200-1,000 kg)	$4.00-4.80
Large (1-10 tons)	$3.70-4.30
Bulk (10+ tons)	$3.50-4.00

Seamless 304 Pipe (1-inch Sch 40S)

Quantity	Price per kg (USD)
Small (under 200 kg)	$6.50-8.00
Medium (200-1,000 kg)	$6.00-7.00
Large (1-10 tons)	$5.50-6.50
Bulk (10+ tons)	$5.00-5.80

Price Factors

Factor	Impact
Size (small diameter)	Higher price per kg
Schedule (thicker wall)	Higher price per kg
Quantity (larger)	Lower price per kg
Seamless vs welded	+30-50%
Special finish (polished)	+10-20%

My Experience
For a bulk order of 10 tons of 2-inch welded 304 pipe, we paid $3.60 per kg. For a small order of 200 kg of the same pipe, the price was $4.80 per kg.

What is the HS code for stainless steel pipe?

The HS code for stainless steel pipe depends on the type: seamless pipe (7304) or welded pipe (7306). For seamless, common codes are 7304.11, 7304.19, and 7304.49. For welded, common codes are 7306.40 and 7306.61.

The specific code depends on the pipe type (seamless/welded), diameter, wall thickness, and application. Always verify with your customs broker for the exact classification.

Stainless Steel Pipe HS Code Summary

Let me summarize the HS codes for stainless steel pipe.

Seamless Pipe (HS 7304)

Code	Description
7304.11	Oil and gas pipe, API standard
7304.19	Other oil and gas pipe
7304.49	Other seamless pipe (general purpose)

Welded Pipe (HS 7306)

Code	Description
7306.40	Welded pipe, circular cross-section
7306.61	Welded pipe, square/rectangular cross-section

HS Code by Pipe Size (Examples)

Pipe Type	HS Code	Example Sizes
Seamless, 304, 1/2-4"	7304.49	1" Sch 40S
Seamless, 316, 1/2-4"	7304.49	1" Sch 40S
Welded, 304, 1/2-4"	7306.40	1" Sch 40S

Welded square tube	7306.61	40×40×2mm

My Experience
For a shipment of welded 304 pipe, we used HS code 7306.40. For seamless, we used 7304.49.

What are the three major methods of steel pipe manufacturing?

The three major methods of steel pipe manufacturing are: seamless (mandrel piercing), longitudinal welded (ERW, LSAW), and spiral welded (SSAW/HSAW).

Seamless pipe is made by piercing a solid billet. Longitudinal welded pipe is made by forming flat strip into a tube and welding the seam longitudinally. Spiral welded pipe is made by forming strip into a spiral and welding the helical seam. Each method has different characteristics for diameter, wall thickness, and cost.

Manufacturing Methods Comparison

Let me compare the three major pipe manufacturing methods.

1. Seamless Pipe

Property	Value
Process	Pierced solid billet
Weld seam	None
Diameter range	1/8" to 24"
Wall thickness	Up to 40mm
Cost	Highest
Best for	High pressure, critical applications

2. Longitudinal Welded Pipe (ERW, LSAW)

Property	Value
Process	Formed strip, welded longitudinally
Weld seam	One straight seam
Diameter range	1/2" to 60"
Wall thickness	1-20mm (ERW), up to 50mm (LSAW)
Cost	Moderate
Best for	General applications

3. Spiral Welded Pipe (SSAW/HSAW)

Property	Value
Process	Formed strip into spiral, welded helical
Weld seam	Helical (spiral)
Diameter range	16" to 120"+
Wall thickness	4-25mm
Cost	Lower
Best for	Large diameters, water lines

My Experience
For a high-pressure chemical line, we used seamless pipe. For a water line, we used spiral welded pipe. For general applications, we used longitudinal welded pipe.

Conclusion

HS code for 316L seamless pipe is 7304.49; for welded, 7306.40. 304 welded pipe costs $3.50-5.00 per kg. HS code for stainless steel pipe is 7304 (seamless) or 7306 (welded). The three manufacturing methods are seamless, longitudinal welded, and spiral welded.
