AI Analysis
Based on the data provided in your <DATA> section, here is the analysis for the specific commodity described as "Brake Booster Fluid".
β οΈ CRITICAL CLARIFICATION: The
<DATA>provided does not contain a classification for "Fluid" (liquid).The data strictly covers "Tubes, pipes and hoses and fittings" (Plastic parts for hydraulic systems).
- If you are importing the liquid "Brake Booster Fluid": It likely falls under Chapter 34 (Detergents), Chapter 38 (Miscellaneous Chemical Products), or Chapter 39 (Plastics - additives), but NOT under the HS Codes
3917.40.00.10or3917.32.00.20provided in your data.- If you are importing the Plastic Hoses/Fittings FOR the Brake Booster System: The classification matches the provided data.
Assuming you intend to import the Plastic Parts/Hoses described in your data (often confused with "fluid" in search queries), here is the breakdown:
π’οΈ Plastic Fittings & Hoses for Brake Systems (Hydraulic Brake Hoses)
HS Code Analysis & 2026 Tariff Strategy
π Scope: Based strictly on the provided
<DATA>for plastic tubes/hoses used in vehicle brake systems. β οΈ Warning: If your shipment contains actual fluid/liquid, this data does not apply. You must classify the liquid separately (likely under HS 3824 or 3913).
π¦ I. HS Code Classification Breakdown (Strict Data Adherence)
The provided data splits plastic brake components into two distinct categories based on construction and specific vehicle application.
Option A: Specialized Brake Fittings (High Priority)
| HS Code | Description | Key Features |
|---|---|---|
| 3917.40.00.10 | Fittings for brake hoses specifically for vehicles of subheadings 8701.21β8701.29 (Tractors) or headings 8702β8705, 8711 (Buses, Cars, Trucks, Motorcycles). | β
Zero Duty on Base + Add-on β Specific Application: Must be for the listed vehicles. β Material: Plastic (Joints, Elbows, Flanges). |
Option B: General Reinforced/Unreinforced Tubes (Standard)
| HS Code | Description | Key Features |
|---|---|---|
| 3917.32.00.20 | Other tubes, pipes and hoses: Not reinforced, no fittings, made of Polyethylene. | β οΈ High Duty: Base 3.1% + Add-on 25.0% = 28.1% β Material: Polyethylene only. β Structure: Unreinforced, without fittings. |
π° II. Tariff Rate详解 (2026 Tax Structure)
π’ 1. HS Code 3917.40.00.10 (Fittings for Brake Hoses)
Target: Precision plastic parts for high-value automotive braking systems.
| Tax Component | Rate | Explanation |
|---|---|---|
| Base Tariff (εΊη‘ε ³η¨) | 0.0% | Duty-Free entry for this specific component. |
| Add-on Tariff (ε εΎε ³η¨) | 0.0% | No Section 301 or IEEPA penalties applicable to this specific sub-category. |
| Total Tax (ζ»η¨η) | 0.0% | Optimal Cost. This is the "Golden Ticket" for brake fittings. |
| Legal Basis | 3917.40.00.10 |
Specific exclusion for brake hose fittings on the listed vehicle headings. |
π Strategic Insight: If your product is a plastic elbow, connector, or joint designed specifically for brake lines on cars/trucks/motorcycles, it enjoys 0% total duty. This is a massive cost advantage over general plastic tubes.
π΄ 2. HS Code 3917.32.00.20 (Other Polyethylene Tubes)
Target: General purpose plastic tubing without fittings.
| Tax Component | Rate | Explanation |
|---|---|---|
| Base Tariff (εΊη‘ε ³η¨) | 3.1% | Standard Most-Favored-Nation (MFN) rate. |
| Add-on Tariff (ε εΎε ³η¨) | 25.0% | Section 301 / China Tariff (Assuming origin from China based on context). |
| Total Tax (ζ»η¨η) | 28.1% | Significant Cost. |
| Legal Basis | 3917.32.00.20 |
General plastic tubing (Polyethylene) without specific brake exemption. |
π Strategic Insight: This rate applies if you are shipping plain polyethylene tubes without the specialized brake fittings, or if the item does not meet the strict definition of "Fittings for brake hoses" under
3917.40. Avoid this code if your part is a specialized fitting.
π οΈ III. Customs Clearance & Classification Advice
β 1. Product Definition Check (Crucial Step)
- Is it Liquid? If you are importing Brake Booster Fluid (the liquid), DO NOT use
3917.40or3917.32.- Likely HS Code: 3403 (Lubricating preparations) or 3824 (Other chemical products).
- Action: Contact a customs broker to classify the liquid separately.
- Is it Plastic Fitting? If you are importing the plastic hose/connector:
- Fitting + Hose assembly? Likely 3917.40.00.10 (0% tax).
- Plain Polyethylene tube? Likely 3917.32.00.20 (28.1% tax).
β 2. Declaration Strategy (To Ensure 0% Tax)
To qualify for 3917.40.00.10 (0% Tax):
1. Description: Must explicitly state "Fittings for brake hoses" or "Brake hose connectors".
2. Application: Must specify "For vehicles of subheadings 8701.21, 8701.22... or headings 8702, 8703..." (e.g., "For SUVs, Sedans, Trucks").
3. Material: Must be Plastic (PE, PP, PVC, etc.).
4. Structure: Must include joints, elbows, flanges, or connections (not just a plain tube).
β Common Mistake:
Declaring "Brake Hose" as "Plastic Tube" (3917.32) to avoid complexity, resulting in 28.1% tax when it should be 0%.
β 3. Documentation Required
- Technical Drawings: Showing the part is a "fitting" (elbow/joint) rather than a continuous tube.
- Vehicle Compatibility List: Proof that the part is designed for cars/trucks/buses (HS 8701-8711).
- Material Certificate: Confirming "Polymer/Plastic" composition.
π IV. Summary Recommendation
| Product Type | Recommended HS Code | Total Tax | Action |
|---|---|---|---|
| Plastic Brake Fitting (Elbow/Joint) | 3917.40.00.10 | 0.0% | β Best Option. Declare as "Fittings for Brake Hoses". |
| Plain Polyethylene Tube | 3917.32.00.20 | 28.1% | β οΈ Avoid if possible. High cost due to add-on tax. |
| Brake Fluid (Liquid) | Not in Data | Unknown | β Do Not Use Above Codes. Requires chemical classification. |
π₯ Pro Tip: If your supplier sends you "Brake Booster Fluid" (the liquid), do not classify it under
3917. That code is strictly for solid plastic tubes and fittings. Classifying liquid as plastic parts will lead to Customs Seizure, Return of Goods, or Heavy Penalties.
Disclaimer: This analysis is based strictly on the provided <DATA> snippet. For actual "Brake Fluid" (liquid), a separate chemical HS classification is required. Always consult a certified customs broker for final declaration.

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
