Q&A
Q1: What is the general HS code for ferrosilicon?
A: The universal HS code category for ferrosilicon is HS Code 7202, which covers all silicon-iron alloys used in steelmaking and casting. Within this category, several sub-codes distinguish products by silicon content, impurities, and special alloy additions. Export documents, commercial invoices, and packing lists must include this code to clear customs smoothly.
Q2: What are the HS sub-codes for different ferrosilicon grades?
A: Ferrosilicon is divided by silicon percentage. The most commonly used sub-codes include:
7202.21 - Ferrosilicon with >55% silicon
Applies to FeSi72, FeSi75, and other high-silicon grades.
7202.29 - Ferrosilicon with ≤55% silicon
Applies to FeSi45, FeSi65, and mid-silicon alloys.
7202.30 - Ferrosilicon containing magnesium
Covers FeSiMg alloys used as nodularizers in cast iron.
7202.99 - Other ferrosilicon types
Used for special-purpose blends that do not fit standard definitions.
These sub-codes align with international customs standards and are recognized worldwide.
Q3: Which HS code should buyers use for FeSi72 and FeSi75?
A: Both FeSi72 and FeSi75 contain more than 55% silicon, so the correct HS code is:
HS Code 7202.21
This is the most frequently used ferrosilicon HS code globally, especially in China, India, Brazil, and major exporting regions.
Q4: Why does the HS code matter for international buyers?
A: Because it directly affects:
Import duties - tax rates often depend on the sub-code
Customs clearance time - incorrect coding may trigger inspection
Compliance and documentation - invoices, COA, and packing lists must match
Shipping and insurance - classification impacts premium categories
Trade statistics and reporting - some countries audit ferrosilicon imports carefully
Using the wrong HS code can delay cargo or even cause the shipment to be re-declared, leading to extra cost and time loss.
Q5: How do exporters choose the right HS code for ferrosilicon shipments?
A: The exporter checks:
Silicon content (the key deciding factor)
Presence of magnesium or other alloying elements
Whether the product is lump, powder, or granular
Destination country rules (some regions have stricter classification)
Most of the time, high-silicon grades like FeSi72/75 automatically fall under 7202.21, while FeSi45/65 fall under 7202.29.
