🏗️ Aluminum Alloy Support Components & Kits (铝合金支撑件套件)
🌐 HS Code Reference & Customs Clearance Guide | 2026 Latest Tariff Analysis | Professional Clearance Strategy 📌 1. Product Definition & Classification: What are "Aluminum Alloy Support Kits"?
Aluminum alloy support kits are structural components used to provide stability, suspension, or fixation in industrial, construction, or mechanical systems. In international trade (specifically US import context based on the provided data), they are categorized based on their primary function and specific application.
⚠️ Key Distinction Point:
- If the item is a pipe hanger/bracket designed to suspend pipes → 7616.99.51.50
- If the item is a general mechanical part for machinery → 8487.10.00.80 or 8487.90.00.80
The classification depends heavily on whether the part is specifically designed for piping systems (Chapter 76) or general mechanical assembly (Chapter 84).

| Section 122 Duty | +10.0% (Steel & Aluminum Import Measures) |
| Total Duty Rate | 37.5% |
| Tax Calculation | CIF Value × 37.5% |
| De Minimis Eligibility | ❌ No (deny_de_minimis) |
| Legal Basis Path | Base Tariff → Section 301 → Section 122 → USITC:7616.99.51.50 |
📌 Explanation:
- This is the most favorable classification for aluminum supports if they are specifically used for pipes.
- Why 37.5%? Base (2.5%) + Section 301 (25%) + Section 122 (10%) = 37.5%.
- Note: Section 122 imposes a 10% duty on certain steel and aluminum imports, regardless of origin, but combined with Section 301 for China, it applies here.
🎯 2. 7616.99.51.30 —— Other Aluminum Parts & Fittings
| Item | Content |

| Total Duty Rate | 35.0% |
| Tax Calculation | CIF Value × 35.0% |
| De Minimis Eligibility | ❌ No (deny_de_minimis) |
| Legal Basis Path | Base Tariff → Section 301 → Section 122 → USITC:8487.10.00.80 |

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
