π I. Product Definition & Classification: Do You Really Understand "Mica"?
Mica Sheet refers to natural or synthetic mica crystals that have been split into thin, flexible sheets. Due to its exceptional electrical insulation, heat resistance, and chemical stability, it is a critical material in the electronics, automotive, and construction industries.
In international trade, it is primarily classified into two main categories based on its state and processing:
1. Raw/Coarse Mica Sheets (Natural Mica): * Description: Unprocessed or roughly trimmed natural mica flakes/sheets. * HS Heading: Typically falls under 2526 (Natural Mica, including aggregate).
2. Processed/Industrial Mica Sheets (Synthetic or Precision-Processed Natural): * Description: Mica sheets cut to specific sizes, thicknesses, or bonded with resins/clay for electrical insulation purposes. * HS Heading: Often falls under 6814 (Articles of mica, including agglomerated mica) or 8545 (Carbon/graphite electrodes if applicable, but pure mica is 6814). * Key Distinction: If it is pure natural mica in raw form β 2526. If it is processed, cut, or bonded for industrial use β 6814.
β οΈ Critical Classification Point: - Raw/Natural Mica Flakes or Rough Sheets β 2526.00.00.00 - Processed Mica Sheets (Cut, Polished, or Bonded with Resin/Clay for Electrical Insulation) β 6814.10.00.00 - Mica Powder β 2526.90.00.00 (Do not confuse sheets with powder!)
π¦ II. HS Code Classification Details (2026 Latest Tariff Authoritative Comparison)
| HS Code | Product Description | Applicable Scenario | Processing Level |
|---|---|---|---|
2526.00.00.00 |
Natural Mica, including aggregate | Raw mica flakes, coarse mica sheets, unprocessed mica | β Raw/Unprocessed |
6814.10.00.00 |
Articles of Mica (including agglomerated mica) | Cut mica sheets, mica sheets bonded with resin/clay, insulated mica plates | β Processed/Manufactured |
2526.90.00.00 |
Mica waste and scrap; Mica powder | Mica dust, crushed mica, industrial waste | β Powder/Waste |
3920.99.00.00 |
Mica-coated plastic films (if any) | Composite materials where mica is a coating on plastic | β Composite |
π Key Reminder: - Most "Mica Sheets" sold for electrical insulation (e.g., in heaters, dryers, electronics) are classified under
6814.10.00.00because they are processed (cut/trimmed) or agglomerated (bonded). - Raw mica from mining or basic splitting is2526.00.00.00. - Do NOT classify processed mica sheets as "Mineral Products" under 2526 if they have been manufactured into specific articles.

π VI. Common Mistakes & Pitfall Guide (Blood & Tears Lessons)
β Mistake 1: Declaring processed mica sheets as "Raw Mica" (2526)
π Consequence: While tariff is same (20%), customs audit may flag for misclassification, leading to delays, fines, or retroactive penalties.
β Mistake 2: Not specifying "Processed" vs "Raw" in invoice π Consequence: Customs request for additional documentation β Clearance delay.
β Mistake 3: Confusing Mica Sheets with "Mica Powder" π Consequence: Wrong HS Code β Rejection or Additional Tax.
β Mistake 4: Ignoring "Agglomerated Mica" declaration π Consequence: If bonded with resin, it is not raw mica. Misdeclaration leads to compliance risk.
β Correct Practice:
"Processed Mica Sheets, Cut to Size, Resin-Bonded, For Electrical Insulation, Model XYZ, ASTM D149 Certified"
π― VII. Conclusion: Professional Declaration, Save Time & Money!
π― Remember the Mantra:
πΉ "Raw is 2526, Processed is 6814. 20% Total Tariff for China. Be Specific, Be Accurate!" πΉ "Mica Sheets are not just minerals; they are manufactured articles. Declare accordingly!"
π Tips:
If your mica sheets are originating from non-China countries (e.g., Madagascar, India, Brazil), you may avoid IEEPA surtaxes, reducing the total tariff to 10% (only USITC surtax). Recommend applying for Advance Ruling if you have complex composite mica products.

About HS Code Classification
The Harmonized System (HS) is an internationally standardized nomenclature developed by the World Customs Organization (WCO) to classify traded products. Over 200 countries use the HS system as the basis for customs tariffs, trade statistics, and import/export regulations.
Each HS code follows a hierarchical structure:
- Chapter (2 digits) β Broad category of goods (e.g., Chapter 84: Machinery and Mechanical Appliances)
- Heading (4 digits) β More specific grouping within the chapter
- Subheading (6 digits) β Internationally standardized breakdown, used by all WCO member countries
- National subdivisions (8-10 digits) β Country-specific extensions for further classification, such as US HTSUS 10-digit codes
Correct HS code classification is essential for smooth customs clearance, accurate duty payment, and compliance with trade regulations. Misclassification can lead to customs delays, overpayment of duties, or penalties.
When importing from CN to US, the applicable tariff rates may include:
- Most-Favored-Nation (MFN) rate β The standard duty rate applied to WTO members
- General rate β Applied to countries without trade agreements
- Trade remedy duties β Additional tariffs such as Section 301 (anti-dumping), Section 232 (national security), or countervailing duties
