📄 Punch Test Paper (Test Sheets for Punching/Perforating Machines)
🌐 HS Code Reference & Customs Clearance Guide | 2026 Latest Tariff Analysis | Professional-Level Clearance Strategy
📌 I. Product Definition & Classification: Do You Really Understand “Punch Test Paper”?
Punch Test Paper, also known as perforation test sheets or punching simulation paper, is a specialized consumable material used in the manufacturing and maintenance of industrial punching machines, die-cutting equipment, and perforation tools. It is primarily used to:
- Test Die Alignment: Ensure that punching dies are correctly aligned with the machine’s press mechanism.
- Check Material Thickness: Verify the compatibility of the punch with different sheet materials.
- Monitor Wear and Tear: Assess the condition of the punching die and the machine’s precision over time.
⚠️ Key Distinction:
- If the paper is standard plain paper used for general testing → May fall under Chapter 48 (Paper products);
- If the paper is pre-treated, coated, or specifically designed for industrial machine calibration/testing → May fall under Chapter 90 (Instruments and apparatus).

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) — Broad category of goods (e.g., Chapter 84: Machinery and Mechanical Appliances)
- Heading (4 digits) — More specific grouping within the chapter
- Subheading (6 digits) — Internationally standardized breakdown, used by all WCO member countries
- National subdivisions (8-10 digits) — 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 — The standard duty rate applied to WTO members
- General rate — Applied to countries without trade agreements
- Trade remedy duties — Additional tariffs such as Section 301 (anti-dumping), Section 232 (national security), or countervailing duties
