Introduction

When exporting or importing Galvalume steel sheets, Galvalume steel coils, Aluzinc steel sheets, or aluminum-zinc coated steel, one of the first customs questions is:
What is the HS code for Galvalume steel sheet exports?
For most standard Galvalume flat-rolled steel products with a width of 600 mm or more, the relevant international HS subheading is 7210.61, covering iron or non-alloy steel flat-rolled products plated or coated with aluminum-zinc alloys.
However, 7210.61 is the international 6-digit HS level. The complete customs code can be different from one country to another. For example, China uses further digits such as 72106100, while the United States uses the HTSUS system and further statistical digits.
This guide explains the Galvalume steel HS code, export classification rules, 72106100, 7210.61, customs declaration requirements, and the difference between HS codes and import tariff rates.

1. What Is the HS Code for Galvalume Steel Sheet?

For standard Galvalume steel sheet with a width of 600 mm or more, the relevant HS subheading is:

HS Code: 7210.61

The official classification describes 7210.61 as:

Flat-rolled products of iron or non-alloy steel, of a width of 600 mm or more, plated or coated with aluminum-zinc alloys.
This classification covers products commonly known in international trade as:

• Galvalume steel sheet
• Galvalume steel coil
• Aluzinc steel sheet
• Aluzinc steel coil
• Aluminum-zinc coated steel
• Aluminium-zinc coated steel
• AZ coated steel
• 55% aluminum-zinc coated steel

U.S. government classification guidance specifically identifies Galvalume sheet coated with an aluminum-zinc alloy under subheading 7210.61.

2. Why Is Galvalume Classified Under 7210.61?

The HS classification is based on the nature of the steel product and its metallic coating, rather than the commercial trademark “Galvalume.”
Galvalume is a flat-rolled steel product coated with an aluminum-zinc alloy.
A typical Galvalume coating contains approximately:

• 55% aluminum
• Zinc as the balance
• Silicon as a minor alloying element

Therefore, it falls under the HS category for flat-rolled iron or non-alloy steel coated with aluminum-zinc alloys.
This is different from conventional galvanized steel.

Galvalume steel

Aluminum-zinc alloy coating → HS 7210.61

Galvanized steel

Zinc coating → commonly HS 7210.49 or another applicable zinc-coated category
The exact classification still depends on the product's specifications and the importing country's tariff schedule.

3. What Does HS Code 72106100 Mean?

If you are exporting Galvalume steel from China, you will commonly encounter:

72106100

This is the Chinese 8-digit tariff code corresponding to products plated or coated with aluminum-zinc alloys.
Chinese customs classification examples include:

• Hot-dip 55% aluminum-zinc steel coil
• ASTM A792 Galvalume coil
• Aluminum-zinc coated steel sheet
• Aluminum-zinc coated steel plate
• Galvalume steel coil

under 72106100, where the product meets the applicable classification requirements.
So a buyer may see:

HS Code: 72106100
on Chinese export documents for Galvalume steel coil or sheet.
However, exporters should remember that the 8-digit code is country-specific, while 7210.61 is the international HS subheading.

4. Does the Galvalume Steel Coil HS Code Differ From Galvalume Sheet?

Not necessarily.
The fact that the product is supplied in a coil or cut sheet does not by itself change the international 6-digit classification.
For example:
Galvalume steel coil, width ≥600 mm
can fall under:
7210.61
Likewise:
Galvalume steel sheet, width ≥600 mm
can also fall under:
7210.61
The more important classification factors include:

• Steel type
• Product form
• Width
• Coating material
• Processing condition
• Country-specific tariff rules

The HS heading 7210 covers flat-rolled iron or non-alloy steel products with a width of 600 mm or more that are clad, plated or coated.

5. What If the Galvalume Steel Is Less Than 600 mm Wide?

This is an important classification point.
The HS structure separates flat-rolled coated steel according to width.
For products with a width of 600 mm or more, aluminum-zinc coated steel is classified under:
7210.61
For products with a width of less than 600 mm, another heading may apply.
For example, the U.S. Customs classification of Galvalume coated steel sheet less than 600 mm wide has been placed under 7212.50.
Therefore, buyers should not automatically use 7210.61 for every narrow Galvalume strip.

Simple rule:

Width ≥600 mm → check 7210.61
Width <600 mm → check the applicable 7212 subheading
The final classification should always be confirmed against the importing country's current tariff schedule.

6. Galvalume HS Code vs. Galvanized Steel HS Code

These two products are often confused during customs declaration.

The international HS classification distinguishes aluminum-zinc alloy coatings from ordinary zinc coatings.
Therefore, Galvalume steel should not automatically be declared using the same HS code as galvanized steel.

7. Does ASTM A792 Determine the HS Code?

Not directly.
ASTM A792/A792M is a technical material specification for aluminum-zinc alloy-coated steel sheet.
The HS code is a customs classification, not a material standard.
For example, a product can be:
ASTM A792 + G550 + AZM150 + Galvalume Steel Coil
The ASTM standard describes the technical characteristics of the material, while the HS code determines how the product is classified for international trade.
A U.S. government classification publication specifically notes that Galvalume sheet manufactured to ASTM A792 falls under the relevant aluminum-zinc alloy coated steel subheadings unless other classification guidelines apply.

8. Does the HS Code Change for AZ50, AZ55 or AZM150 Galvalume?

Usually, the Galvalume coating designation itself does not change the basic HS 6-digit classification when the product remains an aluminum-zinc alloy-coated flat-rolled steel product meeting the same classification conditions.
For example:

• AZ50 Galvalume
• AZ55 Galvalume
• AZM150 Galvalume
• AZM180 Galvalume

can fall under the same 6-digit category:

7210.61

The HS classification is primarily based on the product's customs characteristics rather than simply whether the coating weight is AZ50 or AZM150.

9. What Information Should Be Included in a Galvalume Steel Export Declaration?

For an accurate customs declaration, exporters should prepare clear product information.
Typical information includes:

Product name

Galvalume Steel Coil / Galvalume Steel Sheet

HS code

72106100 for the applicable Chinese 8-digit classification.

Material

Iron or non-alloy steel

Coating

Aluminum-zinc alloy

Width

For example:

1250 mm

Thickness

For example:
0.50 mm

Steel grade

For example:

G550

Galvalume coating

For example:

AZM150

Standard

For example:
ASTM A792/A792M

Product form

• Coil
• Sheet
• Cut-to-length sheet

A clear commercial description helps customs brokers and buyers verify that the declared HS classification matches the actual product.

10. Does the HS Code Determine the Import Duty?

No.
This is another important distinction.
The HS code identifies the product classification, but the actual import duty depends on the destination country's tariff schedule and applicable trade measures.
For example, the United States currently lists 7210.61.00.00 for products plated or coated with aluminum-zinc alloys. The applicable duty can also depend on country of origin and additional measures such as trade remedies.
Therefore, exporters should distinguish between:
HS Code
and
Import Duty / Tariff Rate
They are related, but they are not the same thing.
A Galvalume steel product can have the same HS 6-digit classification while facing different import treatment depending on:

• Country of origin
• Destination country
• Trade agreement
• Anti-dumping duties
• Countervailing duties
• Safeguard measures
• Quotas
• Additional tariff programs

11. What Is the HS Code for Galvalume Steel Exported From China?

For many standard Chinese exports of Galvalume steel sheet and coil, the commonly used Chinese customs code is:

72106100

The corresponding international HS subheading is:

7210.61

Chinese customs trade examples include ASTM A792 aluminum-zinc coated steel coil and Galvalume steel sheet under 72106100.
However, exporters should verify the current Chinese tariff schedule and declaration requirements before shipment, especially when the product has been further processed, slit, painted, perforated, formed or otherwise modified.

12. What Is the HS Code for Aluzinc Steel?

Aluzinc steel is another common commercial name for Galvalume steel.
For standard flat-rolled iron or non-alloy steel products at 600 mm or more in width, plated or coated with aluminum-zinc alloys, the international HS classification is:
7210.61
Therefore, searches such as:

• Aluzinc steel HS code
• Aluzinc coil HS code
• Galvalume coil HS code
• Galvalume sheet HS code
• aluminum zinc coated steel HS code
• aluminium zinc coated steel HS code

often lead to the same fundamental HS subheading.
