π I. Product Definition & Classification: What Exactly is "Brake Fluid Additive"?
Automotive Brake Fluid Additives are specialized chemical formulations designed to enhance the performance, stability, or properties of brake fluids. In international trade, these are generally classified as chemical preparations/additives or lubricant preparations, depending on their base composition and primary function.
β οΈ Key Distinction:
- If the additive is primarily a chemical formulation for adjusting fluid properties (e.g., anti-corrosion, viscosity improvement) without being primarily a lubricant itself, it leans towards Chapter 38.
- If the additive is explicitly a lubricant preparation containing mineral oils, it may fall under Chapter 34.
- Crucial Note: The specific HS code depends heavily on the material composition (e.g., petroleum content) and primary function declared in the customs documentation.
π¦ II. HS Code Classification Details (2026 Latest Tariff Authority Comparison)
Based on the provided data, here are the potential HS Codes for Automotive Brake Fluid Additives:
| HS Code | Product Description | Applicability Scenario | Tax Rate (Total) |
|---|---|---|---|

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
