HS Code for Calculators

Calculators, specifically those defined as mathematical calculating instruments, are classified under HS code 9017.20. This classification is part of Chapter 90, which covers optical, photographic, cinematographic, measuring, checking, precision, medical or surgical instruments and apparatus. Heading 9017 includes drawing, marking-out, or mathematical calculating instruments. While electronic calculators are typically found in Chapter 84, subheading 9017.20 is reserved for non-electronic mathematical calculating instruments. This includes traditional tools such as slide rules, disc calculators, and mathematical calculating cylinders. These instruments function based on logarithmic scales or geometric principles rather than electronic circuitry. The classification is determined by GRI 1 and the specific descriptions provided in the Explanatory Notes to heading 9017. To be classified here, the instrument must be designed for performing mathematical calculations through physical movement or measurement scales. This code is essential for specialized engineering and educational tools that do not rely on digital processing.

Products Included

• Slide rules (linear or circular)
• Mathematical calculating discs
• Cylindrical calculating rules
• Non-electronic mathematical scales for calculation

Common Misclassification

The most common misclassification for calculators is HS code 8470.10, which covers electronic calculators capable of operation without an external source of electric power. Most modern handheld calculators belong in 8470.10. Another error is 9017.30, which covers micrometers and calipers; while these are measuring instruments, they are not designed for mathematical calculation in the same way a slide rule is.

FAQ

What is the HS code for a slide rule?

A slide rule is classified under HS code 9017.20 as a mathematical calculating instrument.

Does 9017.20 include digital calculators?

No, digital or electronic calculators are classified under heading 8470. HS code 9017.20 is specifically for non-electronic mathematical calculating tools.
