π΅ Filter Ball (Filtering Balls / Media)
π HS Code Reference & Customs Clearance Guide | 2026 Latest Tariff Analysis | Professional Clearance Strategy π I. Product Definition & Classification: Do You Know "Filter Balls"?
Filter Balls (also known as Filter Media Balls or Spherical Filter Media) are spherical elements used in water treatment, air filtration, and industrial processes. They are typically made from polyester, polypropylene, or other technical textiles. In international trade, their classification depends heavily on their manufacturing method (woven, non-woven, coated) and technical application.
Because "Filter Ball" is a functional description rather than a material-specific one, Customs may classify them differently based on how they are produced:
β οΈ Key Distinction Points: - Woven/Treated Textile: If the balls are made from fabric that has been sewn or treated for filtration β Look at Chapter 59 (Textile articles). - Non-Woven/Felt: If made from matted fibers without weaving β Look at Chapter 56 (Non-wovens). - Coated/Impregnated: If the base fabric is heavily coated for specific chemical resistance β Look at Chapter 59 (Impregnated textiles).
π¦ II. HS Code Classification Details (2026 Latest Tariff Reference)
Based on the provided data, here are the 5 possible classifications for Filter Balls depending on their specific technical construction:
| HS Code | Product Description (Summary) | Applicable Scenario | Technical Characteristic |

β 2. Declaration Tips (Key Mantra)
π₯ "Material First, Process Second, Function Third!"
| Situation | Correct Declaration Approach | Wrong Approach |
|---|---|---|
| Woven Fabric Balls | Use 5911.40.01.00 or 5911.90.00.80 | Declare as "Plastic Parts" β Wrong Chapter |
| Non-Woven/Felt Balls | Use 5603.93.00.90 | Declare as "Textile Fabric" β Potential Audit |
| Coated/Impregnated Balls | Use 5907.00.80.90 or 5907.00.35.00 | Declare as "Non-woven" β Under-declaring Duties |
β 3. Special Case Handling
| Situation | Handling Advice |
|---|---|
| OEM Custom Filter Balls | Provide design drawings showing the structure (woven vs. non-woven) to justify HS Code selection. |
| Mixed Shipment | If the shipment contains both woven and non-woven balls, split the declaration to apply the correct rate for each (35% vs. 43%). |
| Sample for Testing | Clearly mark as "Samples - Not for Sale" to avoid customs valuation issues, but note that duties still apply. |

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
