HS Code Chapter 81, part of Section XV of the Harmonized System, covers “other base metals, cermets, and articles thereof,” excluding iron and precious metals, and focuses on specialty metals like tungsten, molybdenum, tantalum, magnesium, cobalt, titanium, zirconium, antimony, manganese, and composite materials such as cermets.
Using the global six-digit HS structure (extended to eight digits in India under ITC-HS), accurate classification under Chapter 81 is critical because these high-value materials attract significant duties, are subject to strict compliance checks, and are widely used in fast-growing sectors like aerospace, defense, electronics, batteries, medical devices, and advanced manufacturing.
With the global base metals market exceeding $870 billion and growing steadily, correct HS coding helps businesses avoid customs delays, duty miscalculations, and legal issues while enabling them to capitalize on expanding trade opportunities, benefit from preferential tariffs, and ensure smooth import-export operations through proper documentation, up-to-date tariff knowledge, and alignment with DGFT and WCO guidelines.
What is HS Code Chapter 81?
HS Code Chapter 81 covers “Other base metals, cermets, articles thereof.” It is part of Section XV of the Harmonized System. This chapter excludes precious metals and iron. It focuses on specialty metals and composite materials.
The HS code format uses six digits internationally. India extends this to eight digits. The first two digits identify the chapter. The next two digits show the heading. The last two digits indicate the subheading.
Why Does Chapter 81 Matter?
Base metals in Chapter 81 have high market value. Businesses trading these materials need accurate classifications. Wrong classifications cause customs delays. They result in duty miscalculations. They create legal compliance issues. Accurate HS codes protect your shipments.
The global base metals market was valued at $872.14 billion in 2026. It is growing at 7% annually. By 2032, it will reach $1,320 billion. This growth creates opportunities for traders.
HS Code Structure Explained: How Chapter 81 Works
Breaking Down the Six-Digit Code
Every HS code has a standard structure. Understanding this structure helps you classify products correctly.
- First 2 Digits (Chapter): Identifies the broad product category. For Chapter 81, the digits are “81.”
- Next 2 Digits (Heading): Specifies the metal type within the chapter. Example: “01” for tungsten, “02” for molybdenum.
- Last 2 Digits (Subheading): Provides the most specific product classification. Example: “10” for unwrought material, “90” for waste and scrap.
India’s Extended Eight-Digit Format
India uses the ITC-HS code system. It extends the international six-digit code to eight digits. The additional two digits serve specific tariff and statistical purposes in India.
Example: A tungsten product might be classified as:
- International HS Code: 810110
- Indian ITC-HS Code: 81011010 (with additional specifications)
This extended format helps customs authorities track imports and exports accurately.

- Effective Total: ~23%
Molybdenum (8102):
- Basic Duty: 10%
- IGST: 10%
- Social Welfare Surcharge: 3%
- Effective Total: ~23%
Tantalum (8103):
- Basic Duty: 10%

Important Note: Duty rates may vary based on specific product composition, country of origin, and trade agreements. Always verify current rates with DGFT (Directorate General of Foreign Trade) or your customs broker.
How to Classify Your Products Under Chapter 81
Step 1: Identify the Metal Type
First, determine which specific metal your product contains. Chapter 81 covers 13 different metal categories.
Ask yourself:
- What is the primary metal in this product?
- Is it a pure metal or an alloy?
- What percentage is the primary metal?
- Are there secondary metals present?
Step 2: Check the Product Form
The product form affects its classification. The same metal can have different codes based on its physical state.
Product forms include:
- Unwrought: Raw material without processing (powder, ingots)
- Bars and Rods: Formed but not finished
- Profiles: Special cross-sectional shapes
- Plates and Sheets: Thin, flat forms
- Foil: Very thin sheets
- Wire: Thin, drawn material
- Powder: Ultra-fine particles
- Waste and Scrap: Recycled or rejected material
- Finished Articles: Ready-to-use products
Step 3: Determine the Grade and Purity
Purity levels affect classification. Higher purity materials have different codes than alloys.
Classifications include:
- High Purity (99%+): Primary metal designation
- Standard Grade (85-99%): Standard designation
- Alloy (varies): Alloy heading
- Powder Form: Special powder classification
Step 4: Use Official Classification Tools
DGFT ITC-HS Lookup:
Access at: www.dgft.gov.in

Step 5: Verify with Documentation
Gather supporting documents for classification:
- Product specifications and technical data sheets
- Chemical composition certificates
- Manufacturer’s declaration
- Previous import documentation
- Trade invoices and packing lists
Common Mistakes in HS Code Classification for Chapter 81
Mistake 1: Confusing Alloy Classification
Many traders misclassify alloys as pure metals. An alloy under 99% may belong to a different heading.
Solution: Verify exact metal content percentages. Check if the alloy has its own dedicated classification.
Mistake 2: Ignoring Product Form
The same metal in different forms has different codes. Powder is classified differently than bars.
Solution: Identify the exact physical form of your product. Refer to product form definitions in tariff notes.
Mistake 3: Wrong Waste and Scrap Classification
Waste and scrap materials have specific subheadings. They are not classified as primary products.
Solution: If importing waste or scrap, use the specific waste subheading (usually ending in “90”).
Mistake 4: Missing Composition Details
Products with multiple metal components need careful analysis. The dominant metal determines classification.
Solution: Determine the metal composition percentage. The primary metal (highest percentage) typically drives classification.
Mistake 5: Failing to Update Classification
Tariff codes and regulations change annually. Using outdated codes causes compliance issues.
Solution: Verify current codes with official sources. Update your records quarterly.

How to Calculate Import Duty for Chapter 81 Products
Basic Calculation Formula
Duty calculation follows this structure:
Total Payable Duty = (CIF Value × Basic Duty %) + (CIF Value × IGST %) + (Social Welfare Surcharge)
Where CIF = Cost, Insurance, and Freight value
Step-by-Step Calculation Example
Scenario: Importing tungsten bars under HS Code 8101.94.10
Given Information:
- CIF Value: $10,000
- Basic Duty Rate: 10%
- IGST Rate: 10%
- Social Welfare Surcharge: 3%
Calculation:
- Basic Duty = $10,000 × 10% = $1,000
- IGST on CIF Value = $10,000 × 10% = $1,000
- Social Welfare Surcharge = ($1,000 + $1,000) × 3% = $60
- Total Payable Duty = $1,000 + $1,000 + $60 = $2,060
Final Import Cost = $10,000 + $2,060 = $12,060
Important Considerations
Preferential Trade Agreements:
Products from partner countries may qualify for reduced duties under FTA or RTA.
Exemptions and Concessions:
Specific items may qualify for duty exemptions based on end-use or policy.
Country of Origin:
Tariff treatment varies by country. Verify with commercial invoices and certificates of origin.
Timing Considerations:
Duty rates change with Union Budget announcements. Plan imports strategically around rate changes.
