HS Code for Sealed Flange Parts for Signaling Equipment 2025
TL;DR: Sealed flange parts for signaling equipment typically classify under HS codes 8536.90, 8538.90, or 8485.90 in 2025, depending on electrical features, materials, and function. Accurate classification avoids customs delays and optimizes duties—consult official resources for your specific parts.
What Are HS Codes for Sealed Flange Parts?
HS codes classify traded goods globally using a 6-digit system. For sealed flange parts for signaling equipment, classification hinges on whether they include electrical components or are purely mechanical seals.
These parts ensure watertight connections in traffic lights, railway signals, or industrial alarms. Correct 2025 HS code use prevents fines up to 100% of shipment value.
- First 2 digits: Chapter (e.g., 85 for electrical machinery)
- Next 2: Heading (e.g., 36 for apparatus)
- Last 2: Subheading (e.g., 90 for other parts)
Primary HS Codes for Sealed Flange Parts in Signaling Equipment
Key 2025 classifications for sealed flange parts prioritize function over material. Here's a breakdown:
| HS Code | Description | Best For | 2025 Duty Notes |
| 8536.90 | Other electrical apparatus for circuits ≤1,000V | Electrically conductive flanges with seals | Common 0-5% duties; EU updates for green tech |
| 8538.90 | Parts for HS 8535-8537 apparatus | Dedicated signaling equipment components | Preferential rates under USMCA 2025 |
| 8485.90 | Machinery parts, non-electrical | Pure mechanical seals without circuits | Lowest duties; WCO notes no changes until 2027 |
Use this table for quick reference—verify with national tariff schedules.
