What Is the HS Code for Ferrosilicon 75?

Ferrosilicon 75 is normally classified under HS subheading 7202.21, which covers ferro-silicon containing more than 55% silicon by weight. This classification follows the international Harmonized System (HS), which organizes traded goods using standardized six-digit commodity codes.

The classification can be broken down into three levels:

Ferrosilicon 75 typically contains approximately 75% silicon, with iron making up most of the remaining composition. Its silicon content is therefore above the 55% threshold used to distinguish the two principal ferro-silicon subheadings.

However, customs classification is based on the actual characteristics of the imported goods, not the commercial grade name alone. The material must also satisfy the applicable legal definition of ferro-silicon under heading 7202.

For standard product grades and available forms, see our Ferrosilicon 75 product and supply information.

7202.21 vs. 7202.29: What's the Difference?

The difference between HS 7202.21 and HS 7202.29 is the silicon-content threshold, provided the product is classified as ferro-silicon.

For example, a conventional binary ferrosilicon alloy containing 75% silicon falls within subheading 7202.21. A comparable ferro-silicon product containing exactly 55% silicon would instead fall within 7202.29, because the wording of 7202.21 requires more than 55%.

This distinction also explains why Ferrosilicon 65, Ferrosilicon 72 and Ferrosilicon 75 can share the same international six-digit HS subheading even though their silicon specifications differ.

Why Do Some Websites Show 72022100 and 72022900?

When researching the ferro silicon 75 HS code, buyers may encounter both 72022100 and 72022900 on trade-data websites, shipment databases or supplier directories.

These eight-digit codes begin with different six-digit HS subheadings:

• 72022100 begins with 7202.21, the subheading for ferro-silicon containing more than 55% silicon.
• 72022900 begins with 7202.29, the subheading for other ferro-silicon.

A trade-data page can contain product descriptions submitted by different importers and exporters. Some records may be incomplete, incorrectly classified or grouped together by the database. A shipment description mentioning "75% silicon" under 7202.29 does not establish that 7202.29 is the correct classification for standard Ferrosilicon 75.

If a shipment record conflicts with the published tariff description, verify the original customs documentation and product chemistry rather than copying the code.

Ferrosilicon HS Codes by Country

The international Harmonized System identifies Ferrosilicon 75 under six-digit subheading 7202.21. However, countries and customs territories may add further digits to identify specific tariff lines, statistical categories or import measures.

This means 7202.21 is the internationally harmonized subheading, while the complete customs declaration code depends on the importing country.

Examples of National Tariff Codes

Note: These are classification examples, not a guarantee that a particular shipment qualifies for a listed national tariff line. Verify the current tariff schedule, product composition and any special classification provisions before declaration.

In the United States, for example, two products containing approximately 75% silicon may fall under different national tariff lines if their calcium contents differ. This is why the six-digit HS subheading alone is insufficient for determining the full U.S. customs code.

For the latest tariff descriptions, consult the United States International Trade Commission Harmonized Tariff Schedule or the European Commission's Combined Nomenclature guidance.

Does the HS Code Determine the Import Duty?

The HS classification is one input into determining import duties, but an HS code does not provide a complete landed-duty calculation.

Import charges may also depend on the country of origin, customs value, trade agreements, additional tariff measures and applicable trade-remedy rules. Some measures require separate origin or producer information.

Before importing, confirm the applicable tariff rate and measures using the official customs tariff for the destination country and the planned shipment date.

Does Chemical Composition Affect Classification?

Yes. The actual chemical composition is essential to the customs classification of ferrosilicon. The commercial name "Ferrosilicon 75" indicates the intended grade, but customs authorities may require analytical evidence showing the silicon content and other relevant alloying elements.

For a standard iron-silicon alloy, the silicon content determines the distinction between 7202.21 and 7202.29. However, ferro-alloys containing significant quantities of additional alloying elements may require a more detailed assessment under the legal notes to Chapter 72.

What to Check on the Certificate of Analysis

A COA should represent the actual shipment or an agreed, traceable production batch. A generic catalogue specification can support preliminary review, but it does not necessarily establish the chemical composition of the goods delivered.

For more information about chemical composition and inspection requirements, see our Ferrosilicon 75 specification guide.

Do Ferrosilicon Lumps and Powder Have Different HS Codes?

Not necessarily. The legal definition of ferro-alloys in Chapter 72 includes qualifying material in lumps, granular form and powder form.

Therefore, ordinary crushing, screening or milling does not automatically change the international HS subheading of a ferro-silicon alloy when its composition and classification characteristics remain the same.

For example, standard Ferrosilicon 75 supplied as lumps or powder would generally remain within HS 7202.21 if the products satisfy the relevant legal requirements.

However, a formulated mixture, composite material or product subjected to additional processing may require separate classification review.

When buying crushed or screened ferrosilicon, check the ferrosilicon particle size guide for delivery-size considerations.

Documents Needed for Customs Classification

Importers should prepare a consistent set of commercial and technical documents before shipment. Exact requirements differ by country, but customs authorities or brokers commonly use the following documents to identify the imported material.

How Should Ferrosilicon Be Described on the Invoice?

A commercial invoice should identify the actual product clearly enough for the importing party and customs authorities to recognize it.

For example, a shipment description may specify the commercial grade, actual silicon content, product form and particle-size range.

The example above is hypothetical and is not a declaration of our company's available batch chemistry. Actual invoices must describe the goods supplied and use the verified national customs code.

The contract, invoice, packing list and COA should be consistent. Differences in grade descriptions, material composition or shipment quantities may lead to additional questions during customs review.

How to Verify the HS Code Before Importing

The most reliable way to avoid classification errors is to verify the intended customs code before the shipment is dispatched.

Step 1: Confirm the Exact Ferrosilicon Grade

Request the agreed product specification and chemical analysis. Confirm that the material is ordinary ferro-silicon or identify any significant additional alloying elements that may affect classification.

Step 2: Check the International Six-Digit Subheading

For standard Ferrosilicon 75 containing more than 55% silicon by weight, the applicable international subheading is normally 7202.21.

Confirm that the product also meets the legal definition of ferro-silicon under the relevant Chapter 72 provisions.

Step 3: Find the Complete National Tariff Code

Look up subheading 7202.21 in the current tariff schedule of the importing country. Review the national subdivisions and any conditions relating to chemical composition.

Do not assume that the final two or four digits used by another country are valid for your destination market.

Step 4: Review Applicable Import Measures

Confirm the relevant tariff treatment, origin requirements, trade-remedy measures and any other import restrictions that may apply to the shipment.

The customs duty payable cannot be established from the six-digit HS code alone.

Step 5: Confirm Documents With Your Customs Broker

Provide your broker with the product specification, batch COA and draft commercial invoice. Ask them to verify the final declaration code against the destination country's official tariff.

If the classification remains uncertain, consider requesting a formal advance or binding tariff ruling where the importing jurisdiction provides this procedure.

Completing these checks before shipment can reduce the risk of incorrect declarations, customs queries and avoidable clearance delays.
