π I. Product Definition & Classification: Do You Understand "Filtration Parts"?
Parts for centrifuges, filtration, or purification machinery are critical components used in water treatment, industrial chemical processing, air purification, and HVAC systems. In international trade, these parts are strictly categorized based on their specific application and functional compatibility. Misclassification often leads to severe tariff penalties due to Section 301 and IEEPA trade restrictions.
The data provided focuses on two main categories: 1. HVAC/Air Purification Related Components (HS Code 8415.90.80.85) 2. Water Filtration/Purification Specific Parts (HS Codes 8421.99.01.40 / 8421.99.01.80)
β οΈ Key Distinction Point:
- If the part is specifically matched for air conditioning, ventilation, or general air purification systems β It is treated as a component of air conditioning/purification systems. - If the part is specifically designed for water filtration or water purification machinery β It falls under specific water treatment subheadings.
π¦ II. HS Code Classification Details (2026 Latest Tariff Authority Alignment)
| HS Code | Product Description | Applicable Scenario | Key Characteristic |
|---|---|---|---|
8415.90.80.85 |
Parts for filtration or purification apparatus, matched for use, considered relevant components for air conditioning or purification systems. | HVAC filters, air purifier frames, heat exchanger parts for AC units. | Air-Related: Tied to climate control or air quality systems. |
8421.99.01.40 |
Parts for filtration or purification apparatus, with uses consistent with water filtration or purification, belonging to component class. | Water filter housings, RO membrane supports, water treatment cartridges. | Water-Related: Dedicated to liquid purification. |
8421.99.01.80 |
Parts for filtration or purification apparatus, uses fully consistent with filtering or purifying mechanical appliances and their parts. | General industrial filtration parts not specifically limited to water but clearly for purification machinery. | General Purification: Broad category for machinery parts if not HVAC. |
π Important Reminder:
- "Matched Use" is Critical: You must provide documentation proving the part's specific use. A generic "filter part" will likely be scrutinized heavily. - Don't Mix Categories: Shipping water filter parts as "HVAC parts" (or vice versa) may trigger customs audits for misdeclaration, especially given the high tariff rates below.
π° III. 2026 Latest Tariff Rate Detailed Explanation (Including Additional Taxes & Policy Add-ons)
β Applicable Country: United States (US)
β Origin: China (CN)
β Effective Date: Current trade restrictions apply (Section 301 & IEEPA)
π― 1. 8415.90.80.85 ββ Parts for Air Conditioning/Purification Systems
| Item | Content |
|---|---|
| Base Tariff Rate | 1.4% (Ad Valorem) |
| Additional Tariff (Section 301) | +7.5% (Standard 301 List 4B addition for this subcategory) |
| Section 122 Tariff (Steel/Aluminum/Copper) | +10% (Applicable if the part contains significant steel, aluminum, or copper content and is classified under specific metal product provisions) |
| Steel, Aluminum, Copper Product Surcharge | +50% (CRITICAL: If the part is classified as a steel/aluminum/copper product under specific trade rules, this surcharge applies. Note: The data explicitly lists "50%" for steel/aluminum/copper products in this line item.) |
| Total Maximum Tax Rate | 68.9% |
| Tax Calculation Basis | CIF Value Γ 68.9% |
| De Minimis Exemption | β NOT Eligible (High tariff rates exceed de minimis thresholds and are subject to strict scrutiny) |
| Legal Authority Path | HTSUS:8415.90.80.85 β Section 301: List 4B β Section 122: Steel/Al/Cu Surcharge β IEEPA: 233 |
π Explanation:
- This is an extremely high tariff bracket. - The 50% surcharge is the primary driver of cost. This applies if the part is identified as a steel/aluminum/copper product under Section 232 or related provisions. - Even without the 50% surcharge, the base + 7.5% + 10% totals 18.9%, which is still significant. However, the provided data indicates a 68.9% total, implying the 50% metal surcharge is active.
π― 2. 8421.99.01.40 & 8421.99.01.80 ββ Parts for Water Filtration/Purification
| Item | Content |
|---|---|
| Base Tariff Rate | 0.0% (Free) |
| Additional Tariff (Section 301) | +25.0% (Standard 301 List 4A/4B addition for machinery parts) |
| Section 122 Tariff | +10% (Specific addition for these filtration parts under certain interpretations) |
| Total Tax Rate | 35.0% |
| Tax Calculation Basis | CIF Value Γ 35.0% |
| De Minimis Exemption | β NOT Eligible (Due to Section 301 and IEEPA restrictions on Chinese origin goods in this category) |
| Legal Authority Path | HTSUS:8421.99.01.40/80 β Section 301: List 4B β IEEPA: 233 β Section 122: 10% surcharge |
π Explanation:
- While the base rate is 0%, the 35% total effective rate makes these imports expensive. - The 25% Section 301 tariff is the standard penalty for Chinese machinery parts. - The 10% Section 122 tariff is an additional layer, possibly related to specific filtration material restrictions or administrative classifications. - Total 35% is high but lower than the 68.9% for HVAC-related parts.
π οΈ IV. Customs Clearance Practical Advice (Real-World Pitfall Avoidance)
β 1. Documentation Checklist (Essential)
| Document | Required? | Purpose |
|---|---|---|
| β Product Specification Sheet | βοΈ | Must clearly state: "Part for Water Filter Model XYZ" or "HVAC System Component". |
| β Bill of Materials (BOM) | βοΈ | Identifies material composition (Steel/Al/Cu) to accurately apply Section 122 rules. |
| β Commercial Invoice | βοΈ | Must match the HS Code description exactly. Do not use generic terms like "Filter Part". |
| β Country of Origin Certificate | βοΈ | Essential for confirming Chinese origin and applying correct Section 301/IEEPA rates. |
| β Photos of Label/Markings | βοΈ | To prove intended use (e.g., "For Water Purification Only"). |
β 2. Declaration Strategy (Key Mantras)
π₯ "Match Use, Label Clearly, Avoid Metal Traps!"
| Scenario | Correct Declaration | Risk of Error |
|---|---|---|
| Water Filter Housing (Plastic/Metal) | 8421.99.01.40 (35%) |
Misdeclaring as "Plastic Part" (0%) β Audit & Penalty |
| AC Filter Frame (Steel) | 8415.90.80.85 (68.9%) |
Misdeclaring as "Steel Sheet" (0% base + 25%?) β High Risk of 50% Surcharge if caught |
| General Machinery Filter | 8421.99.01.80 (35%) |
Mixing with water parts β Confusion, delays |
| Part with Steel/Aluminum Content | Ensure HS Code triggers Section 122 | If HS Code doesn't reflect material, you may be under-declaring taxes. |
β 3. Special Considerations
| Issue | Handling Advice |
|---|---|
| Steel/Aluminum Content | For HS Code 8415.90.80.85, if the part is >20% steel/aluminum/copper by weight, the 50% surcharge may apply. Consult a trade lawyer to see if "parts" exemptions apply. |
| Section 122 Tariff (10%) | This is a specific administrative tariff. Ensure your customs broker is aware of this addition to avoid underpayment. |
| De Minimis (Section 321) | Do not rely on $800 de minimis exemption. These goods are subject to Section 301 and IEEPA, which override de minimis privileges for Chinese-origin goods in many cases. |
| Origin Marking | Clearly mark "Made in China" to avoid penalties for non-origin marking. |
π V. Global Market Comparison (2026 Latest)

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
