What Is the HS Code for Eddy Current Flaw Detectors?
The primary HS code for eddy current flaw detectors is 9031.80 worldwide in 2025.
These non-destructive testing (NDT) devices use electromagnetic fields to detect surface and subsurface flaws in conductive materials.
Essential in industries like aerospace, oil & gas, and manufacturing, accurate HS classification ensures tariff compliance.
HS Code Structure for Measuring Instruments Like Flaw Detectors
HS codes follow a 6-digit global standard from the World Customs Organization (WCO).
- Chapter 90: Optical, photographic, measuring, checking, precision instruments
- Heading 31: Measuring or checking instruments, appliances and machines, not specified elsewhere
- Subheading 80: Other instruments and apparatus
Countries extend to 8-12 digits for local tariffs, e.g., 9031.80.90 in the EU.
Confirming 9031.80 as Your Flaw Detector HS Code
Eddy current flaw detectors fit perfectly under HS 9031.80 for 2025 shipments.
| HS Code | Description | Product Examples | Avg Duty 2025 |
| 9031.80 | Other measuring/checking instruments | Eddy current flaw detectors, thickness gauges | 0-4% |
| 9031.49 | Optical profile projectors | Optical-based alternatives | 1-5% |
| 9031.10 | Revolution counters | Multi-function speed testers | 0-3% |
Always match your device's primary function to avoid misclassification.

These variations impact duties and compliance requirements.
How to Find the Correct HS Code for Your Flaw Detector (Step-by-Step)
Use this proven 5-step process for accurate 2025 HS classification.
- Review product specs: Confirm eddy current NDT function.
- Locate Chapter 90: Search WCO HS nomenclature online.
- Select 9031.80: Matches non-optical measuring devices.
- Add country digits: Use official tariff databases.
- Vali Cross-check with customs or tools.
Factors That Could Change Your HS Code from 9031.80
Certain features may shift eddy current flaw detectors to alternate codes.
- Optical components: May fall under 9031.49
- Ultrasonic integration: Consider 9031.10
- Portable battery-powered: Check 9030.84 if multi-function
- High-precision lab use: Possible 9027.50
- Export-controlled tech: Additional ITAR/EAR markings
Common Misclassifications of Eddy Current Flaw Detectors
Avoid these frequent HS code errors for flaw detectors in 2025.
- Confusing with ultrasonic testers (9031.10)
- Mistaking for magnetic detectors (9031.80 still applies)
- Ignoring country-specific digits
- Overlooking multi-function rules
- Forgetting de minimis changes for low-value shipments
