🌐 HS Code Reference & Customs Clearance Guide | 2026 Latest Tariff Analysis | Professional Entry Strategy
📌 1. Product Definition & Classification: Do You Really Understand "Terminal Blocks"?
Terminal blocks, commonly referred to as "terminal blocks" or "connectors," are essential components in electrical engineering used to connect, terminate, and distribute electrical wires in control cabinets, distribution panels, and switchgear. In international trade, their classification depends heavily on function, voltage rating, and physical form.
There are two main classification paths: * As Parts of Switching Devices/Panels (HS 8538): If the terminal block is specifically designed as a spare part for control panels, distribution boards, or switching devices. * As Electrical Connection Devices/Conductors (HS 8536/8544): If the terminal block is viewed as a standalone electrical connector or a component of insulated conductors for circuits up to 1,000V.
⚠️ Key Distinction Point:
- If classified as a part/assembly for a panel/distribution board →归入 8538.90.81.60 / 8538.90.81.80
- If classified as a standalone electrical connector (up to 1,000V) → 归入 8536.90.40.00 / 8536.90.85.30
- If classified as part of insulated conductors/cables → 归入 8544.49.30.80 / 8544.49.90.00
📦 2. HS Code Classification Details (2026 Latest Tariff Authority Comparison)
| HS Code | Product Description | Application Scenario | Voltage/Function |
|---|---|---|---|
8538.90.81.60 |
Parts of control panels/distribution boards | Control cabinet wiring terminals, specifically as parts of the panel assembly | Part of Panel/Switchgear |
8536.90.40.00 |
Other connectors for circuits ≤ 1,000V | Standalone terminal blocks for electrical回路, implying voltage ≤1,000V | Electrical Connector |
8538.90.81.80 |
Other parts of switching devices/panels | Connection assemblies for control panels, distribution boards, switching devices | Part of Panel/Switchgear |
8544.49.30.80 |
Insulated conductors accessories (Copper/Copper-core) | Connection components for insulated conductors, often copper-based, <1,000V | Insulated Conductor Accessory |
8544.49.90.00 |
Other insulated conductors/electrical connectors | Electrical connectors falling under the category of insulated conductors | Insulated Conductor/Connector |
8536.90.85.30 |
Other electrical connection devices (≤1,000V) | Electrical connection devices for low-voltage equipment, voltage ≤1,000V | Electrical Connection Device |
🔍 Key Reminder:
- Control Cabinet Context: If the terminal block is sold specifically as a "part for a control cabinet/panel", it strongly points to 8538.
- Electrical Function Context: If the terminal block is sold as a generic electrical connector or for wiring (conductor-related), it points to 8536 or 8544.
- Voltage Threshold: Most of these codes imply a voltage of ≤ 1,000V. High-voltage terminals (>1,000V) would fall under different subheadings not listed in the provided data.

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
