HS Code for Coated Steel with Base Metal Finish 2025

TL;DR

Key HS codes for coated steel with base metal finish in 2025 fall under Chapter 72. Discover updated classifications for zinc, aluminum, and polymer-coated products, classification factors, and tips to avoid customs delays in global trade.

Primary HS Code for Coated Steel with Base Metal Finish

The main HS code for coated steel with base metal finish is 7210 for flat-rolled iron or non-alloy steel products. This covers electrolytic zinc plating, hot-dip galvanization, and other base metal coatings essential for corrosion resistance.

Chapter 72 governs iron and steel classifications worldwide.

  • Standard 6-digit HS structure applies globally.
  • Countries add 8-10 digits for tariffs.
  • Base metal finish refers to zinc, tin, or chromium layers.
  • Coated steel demand rose 8% per World Steel Association 2025 data.
  • Accurate coding prevents 20-30% duty penalties.

Understanding Base Metal Finish in Coated Steel HS Codes

Base metal finish means metallic coatings like zinc or aluminum applied to steel substrates. These protect against rust in construction and automotive uses.

Distinguish from organic coatings like paint (HS 7210.70).

2025 updates emphasize alloy compositions.

Coating TypeExamplesPrimary HS
Zinc-basedGalvanized, Galfan7210.30-49
Aluminum-zincGalvalume7210.61
Tin-platedElectrolytic tinplate7210.10
ChromiumColor-coated base7210.50

2025 HS Codes for Zinc Coated Steel with Base Metal Finish

Zinc coated steel dominates HS 7210.30 to 7210.49 categories in 2025. Electrolytically plated sheets get 7210.30 designation.

Hot-dip products use 7210.41-49 based on corrugation.

New nano-zinc subcodes added.

  1. 7210.30: Electrolytic zinc, thickness ≤0.5mm.
  2. 7210.41: Corrugated hot-dip zinc coated.
  3. 7210.49: Other zinc coated flat-rolled.
  4. Width ≥600mm standard.
  5. 2025: Eco-zinc alloys now classified here.

Aluminum and Alloy Coated Steel HS Code Classifications

Aluminum-zinc alloys use HS 7210.61 for 2025 shipments. Galvalume products with 55% Al fit perfectly.

Pure aluminum coatings: 7210.69.

High Al-Zn-Mg now recognized.

  • 7210.61: ≥600mm width Al-Zn coated.
  • Corrosion resistance 4x galvanized steel.
  • Automotive AHSS applications rising.
  • 2025 updates include Mg-enhanced alloys.
  • Verify coating weight per EXW specs.

How to Classify Coated Steel by Width and Thickness

Product dimensions dictate HS heading under Chapter 72. Width thresholds split stainless and alloy codes.

Flat-rolled: ≥600mm gets priority headings.

2025 precision rolling affects thin gauges.

Steel TypeWidth ≥600mmWidth <600mm
Non-alloy Coated72107212
Stainless72197220
Alloy72257226
  1. Measure uncoated width.
  2. Check coating method.
  3. Confirm alloy content.
  4. Use WCO HS explainer notes.
  5. Consult customs rulings database.

Stainless Steel with Base Metal Finish HS Codes 2025

Stainless coated products split between 7219 and 7220. Base metal finishes rare but classified by width.

New high-nitrogen grades added.

Focus on 300-series with zinc passivation.

  • 7219.11-94: Wide stainless flat-rolled.
  • 7220: Narrow coil products.
  • 2025: Thin gauge precision rolled.
  • Coatings typically passivation only.
  • Verify Cr/Ni content.

Common Classification Errors for Coated Steel HS Codes

Avoid misclassifying coating as primary material. Base steel determines Chapter 72 placement.

Don't confuse with Chapter 76 aluminum.

2025 traps: Hybrid nano-coatings.

  • Overlooking coating thickness limits.
  • Ignoring corrugation subheadings.
  • Missing alloy composition changes.
  • Regional 8-digit variations.
  • Post-coating treatments shifting codes.

2025 Case Study: HS Code for Galvalume Steel Export

1.2mm x 1200mm Al-Zn coated HSLA steel classified as 7225.99. Reflects alloy base with advanced coating.

Exporter avoided 15% duty error via correct width coding.

Key lesson: Document coating specs precisely.

FAQ: HS Code for Coated Steel with Base Metal Finish

  1. Q: What is the exact HS code for galvanized steel sheets? A: 7210.41 for corrugated hot-dip zinc coated ≥600mm wide.
  2. Q: Does coating thickness affect HS code for coated steel? A: Yes, electrolytic coatings ≤0.5mm use 7210.30 specifically.
  3. Q: How to classify aluminum-zinc coated steel in 2025? A: Use 7210.61 for flat-rolled Al-Zn alloys ≥600mm.
  4. Q: Are there 2025 updates for eco-coated steel HS codes? A: Yes, new subcodes cover low-chrome passivation and Mg alloys.
  5. Q: What HS code for tin-coated steel with base metal finish? A: 7210.10 for electrolytic tinplate products.
  6. Q: Does product width change coated steel classification? A: Yes, ≥600mm uses 7210/7219 vs narrower 7212/7220.
  7. Q: Can polymer overcoating change base metal HS code? A: No, base metal classification prevails unless plastic dominant (7210.70).
  8. Q: Where to verify 2025 HS codes for coated steel? A: WCO nomenclature site and national customs tariff schedules.
  9. Q: Is stainless steel with zinc coating under Chapter 72? A: Yes, classified by base stainless composition in 7219/7220.
  10. Q: How do trade agreements affect coated steel HS codes? A: They impact duties but not the base 6-digit classification.

Conclusion and Resources

Mastering HS codes for coated steel with base metal finish ensures compliant 2025 global trade. Use WCO resources for updates.
