π Insulated Electric Fittings: The Ultimate Guide to HS Codes, Tariffs & Customs Clearance (2026 Update)
π HS Code Reference & Customs Clearance Guide | Latest 2026 Tariff Analysis | Professional Clearance Strategy
π 1. Product Definition & Classification: Do You Really Understand "Insulated Electric Fittings"?
Insulated Electric Fittings are critical components in electrical systems, used for connecting, protecting, or organizing wires and cables. They are wholly made of insulating material (like plastics, ceramics, or rubber), except for minor metal components (e.g., threaded inserts) added solely for assembly purposes during molding.
These fittings exclude: - Insulators of Heading 8546 (e.g., standalone high-voltage porcelain insulators). - Conduit tubing and joints of base metal lined with insulating material (these fall under Chapter 73 or 74, not 8547).
β οΈ Key Distinction:
- If the fitting is wholly insulating (plastic/ceramic), it belongs in HS Code 8547.
- If it is metal with an insulating lining, it belongs in Chapter 73/74, NOT 8547.
- If it is a standalone insulator (not a fitting), it belongs in HS Code 8546.
π¦ 2. HS Code Classification Details (2026 Latest Tariff Cross-Reference)
| HS Code | Product Description | Applicable Scenario | Insulating Material? |
|---|---|---|---|
| 8547.90.00.10 | Other insulating fittings (plastics, ceramics, etc.) | General-purpose insulated connectors, bushings, sleeves | β Yes |
| 8547.20.00.00 | Insulating fittings of plastics | Plastic conduit connectors, plastic cable glands | β Yes (Plastic) |
| 3926.90.45.10 | Gaskets, washers, seals, O-rings (plastics) | Insulating gaskets or seals used in electrical equipment | β Yes (Seals) |
| 3926.30.50.00 | Fittings for furniture, coachwork, etc. (plastics) | Decorative or structural plastic fittings (NOT electrical) | β No (Non-electrical) |
| 8536.90.40.00 | Electrical terminals, splices, couplings (β€1,000V) | Plastic terminal blocks, wire nuts, splices | β Yes (Electrical Connectors) |
| 8536.90.85.85 | Other electrical apparatus (β€1,000V) | Miscellaneous electrical connectors, non-insulated parts | β οΈ Mixed (Metal/Plastic) |
π Critical Reminder:
- 8547 is for insulating fittings (e.g., bushings, sleeves).
- 8536 is for electrical apparatus for switching/protecting (e.g., terminal blocks, plugs).
- 3926 is for general plastic articles (e.g., gaskets, furniture fittings).
- Do NOT confuse "insulating fittings" with "insulators" (8546) or "metal-lined conduits" (73/74).
π° 3. 2026 Latest Tariff Rate Details (Including Surcharges & Policy Add-ons)
β Applicable Country: USA (US)
β Country of Origin: China (CN)
β Effective Date: From November 10, 2025 (and subsequent imports)
π― 1. HS Code 8547.90.00.10 ββ Other Insulating Fittings
| Item | Content |
|---|---|
| Base Tariff | 0% (ad valorem) |
| USITC Surcharge | +0% (Note: No Section 301 surcharge listed for this specific subheading in the data) |
| Steel/Aluminum/Copper Surcharge | +50% (If metal components are present and classified under this surcharge rule) |
| Total Tariff | 50.0% |
| Tax Calculation | CIF Value Γ 50% |
| De Minimis Eligibility | β No (High tariff prevents de minimis) |
| Legal Basis Path | USITC:8547.90.00.10 β FOOTNOTE:Steel/Aluminum/Copper 50% |
π Explanation:
- Although the base tariff is 0%, the 50% surcharge on Steel/Aluminum/Copper products applies if the fitting contains metal components (e.g., threaded sockets) incorporated during molding.
- Total tax = 50%. This is a very high tariff and must be factored into cost calculations.

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
