⚙️ Valve Components (阀门配件)
🌐 HS Code Reference & Customs Clearance Guide | 2026 Latest Tariff Analysis | Professional Clearance Strategy
📌 I. Product Definition & Classification: What Exactly Are "Valve Components"?
Valve components are essential spare parts and accessories used in industrial piping, fluid control, and mechanical systems. In international trade, they are often misclassified because they can fall under either iron/steel制品 (Chapter 73) or machinery parts (Chapter 84/8487).
The core difference lies in material specificity and dedicated use:
- Generic Metal Parts (Steel/Iron): If the component is a generic metal piece (flange, bolt, generic bracket) without specific valve engineering, it often falls under Chapter 73.
- Dedicated Valve Parts: If the component is specifically shaped for use with valves (e.g., valve stem, bonnet, specific gaskets), it logically belongs under Chapter 84 (Machinery).
⚠️ Key Distinction Point:
- If the material is Steel/Iron and no specific valve function is proven → 7326.19.00.80 / 7326.90.86.88
- If it is a Generic Mechanical Part (not specific to valves) → 8487.90.00.40 / 8487.90.00.80
- If it is Specifically for Valves (dedicated use) → 8481.90.90.60 / 8481.90.90.85
📦 II. HS Code Classification Details (2026 Latest Tariff Authority Comparison)
| HS Code | Product Description | Applicable Scenario | Material Conflict? |
|---|---|---|---|
7326.19.00.80 |
Other articles of iron or steel | Generic metal valve accessories; "Catch-all" for steel products | ❌ None (Steel) |
7326.90.86.88 |
Other articles of iron or steel | Valve parts inferred as metal/steel due to lack of conflict | ❌ None (Steel) |
8481.90.90.60 |
Parts of valves | Dedicated valve parts; logical fit for "valve accessories" | ❌ No conflict |
8481.90.90.85 |
Other parts of valves | Dedicated valve parts; default preference for valve components | ❌ No conflict |
8487.90.00.40 |
Other mechanical parts | Generic mechanical parts; no obvious material conflict | ❌ No conflict |
8487.90.00.80 |

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) — Broad category of goods (e.g., Chapter 84: Machinery and Mechanical Appliances)
- Heading (4 digits) — More specific grouping within the chapter
- Subheading (6 digits) — Internationally standardized breakdown, used by all WCO member countries
- National subdivisions (8-10 digits) — 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 — The standard duty rate applied to WTO members
- General rate — Applied to countries without trade agreements
- Trade remedy duties — Additional tariffs such as Section 301 (anti-dumping), Section 232 (national security), or countervailing duties
