Ruler Centimeter Scale

📏 Ruler with Centimeter Scale (Measuring Instruments for Length, Handheld)

📌 One: Product Definition & Classification – Do You Really Know What a Ruler Is?

A ruler with a centimeter scale is a fundamental measuring tool used in offices, schools, engineering, and crafts. It is designed for manual, handheld measurement of length and is typically made of plastic, metal, or wood. In international trade, it falls under precision measuring instruments, but not all rulers are treated the same.

⚠️ Key Classification Rule:
- If the ruler has only a linear scale (e.g., cm/mm) and no mechanical or electronic components, it is classified as a simple measuring tool.
- If it includes adjustable mechanisms, sliding parts, or digital readouts, it may fall under different HS codes (e.g., 9017.20.80.80).

📦 Two: HS Code Classification Details (2026 Latest Tariff Authority Comparison)

🔍 Critical Insight:
- A standard plastic or wooden ruler with only centimeter markings → 9017.80.00.00
- A ruler with a sliding head, adjustable scale, or integrated protractor → 9017.20.80.80
- Do not confuse with drafting instruments like compasses or T-squares — those fall under different subheadings.

✅ Applicable Country: United States (US)
✅ Origin: China (CN)
✅ Effective Date: November 10, 2025 (including subsequent imports)

🎯 1. 9017.80.00.00 — Basic Handheld Measuring Instruments (e.g., Simple Rulers)

📌 Explanation:
- This is a low-risk, zero-tariff category for basic rulers. - No Section 301 or IEEPA tariffs apply to standard rulers. - Perfect for bulk school supplies or office goods.

🎯 2. 9017.20.80.80 — Other Drawing/Marking Instruments (e.g., Advanced Rulers)

📌 Important Note:
- This 29.6% rate applies only if the ruler has special features (e.g., sliding scale, dual-unit markings, non-standard material, or integrated protractor). - Even if the product looks like a ruler, if it has mechanical parts, it may be classified here. - Do not assume all rulers are 0% — misclassification = heavy penalties.
