π I. Product Definition & Classification: What is a "Perforated Card Base"?
In the context of international trade and historical data processing, a "Perforated Card Base" refers to the raw material used to create punched cards (also known as IBM cards). These are sheets of paperboard or pasteboard, pre-cut into standard sizes (e.g., 73mm x 105mm), featuring specific perforation patterns or grooves to facilitate the punching of holes by specialized machines.
Crucial Distinction:
It is NOT the finished punched card containing data. It is the substrate/material itself.
Key Classification Criteria: 1. Material Composition: Primarily cellulose-based (paper/paperboard) or sometimes plastic/polymer-based. 2. Processing Status: It is either: * Raw Stock: Plain paperboard/paper sheets, possibly slitted or cut to size, but not yet printed with data fields or fully punched. * Pre-printed/Pre-cut: Sheets ready for punching, often with guide marks. 3. Intended Use: Exclusively for manufacturing punched cards for data processing.
β οΈ Critical Classification Point:
- If it is raw paper/paperboard merely cut to size β It falls under Chapter 48 (Paper and Paperboard).
- If it is plastic-based β It falls under Chapter 39 (Plastics).
- It does NOT belong in Chapter 85 (because it is not a finished data storage device or a component of a machine, but rather the consumable medium).
- It does NOT belong in Chapter 96 (because it is not yet a "stationery article" in the form of a finished card; it is the base material).
π¦ II. HS Code Classification Details (2026 Latest Tariff Authority Comparison)
The most common classification for "Perforated Card Base" is under Paper and Paperboard. If the base is plastic, it falls under plastics. Below is the detailed breakdown for the most prevalent type: Paper-Based.
| HS Code | Product Description | Applicable Scenario | Material |
|---|---|---|---|
4820.10.00.00 |
Registers, account books, order books, receipt books, letter pads, memorandum pads, diaries and similar articles; blotting-pads; blank book forms; carbon sets; address plates; perforated paper stock | Raw perforated card stock for punched cards; paper bases for label printing; generic punched card blanks | β Paper/Paperboard |
4811.51.00.00 |
Self-copy paper and other copy and reproducing papers, whether or not printed, in rolls or sheets... | Less common for card bases; usually for copy paper. Avoid unless specified as copy stock. | β Paper |
3921.90.90.00 |
Other plates, sheets, film, foil and strip, of plastics | If the "card base" is made of plastic (e.g., PVC card blanks for laser printing) | β Plastic |
π Key Reminder:
-4820.10.00.00is the correct and standard HS Code for "perforated paper stock" used for punched cards.
- Do NOT use8523.21.00.00(Magnetic or optical media) or8523.49.00.00(Other recorded media). Punched cards are not magnetic or optical; they are mechanical.
- If the cards are already punched and contain data, they are generally not classified as merchandise for import/export in bulk but as "used goods" or subject to specific data security regulations. However, the blank or unpunched base is clearly4820.10.00.00.

π Explanation:
- While the base rate for paper is low, Section 301 tariffs heavily impact Chinese-manufactured paper products.
- "Perforated paper stock" is explicitly listed in many trade exclusion lists but often not excluded from surtaxes.
- The 35% total rate is significant. Importers must calculate if the cost of the card base justifies the high tariff.
π― 2. 3921.90.90.00 ββ Plastic-Based Card Bases (PVC/PET Blanks)
| Item | Content |
|---|---|
| Base Tariff Rate | 0% - 5% (varies by plastic type) |

π Note:
- Plastic card blanks (e.g., for ID cards, credit cards) are increasingly common. They are not "punched cards" in the historical sense but serve similar blank media functions.
- If these are recorded (i.e., already printed with data), they may fall under different HTS codes (e.g.,8523.49), but blank plastic sheets are3921.90.90.00.
π οΈ IV. Customs Clearance Practical Advice (Battle-Tested Pitfall Guide)
β 1. Documentation Checklist (Missing any = Delay)
| Document | Required? | Description |
|---|---|---|
| β Product Specification | βοΈ | Must clearly state: "Unpunched, blank card base," dimensions, material (paper/plastic). |
| β Material Declaration | βοΈ | Explicitly state: "100% Paper," "PVC," or "PET." Do not say "Plastic" if it is paper. |
| β Commercial Invoice | βοΈ | Description: "Perforated Paper Stock for Punched Cards" or "Blank Card Base." Avoid "Computer Cards" (ambiguous). |
| β Packing List | βοΈ | Show weight, dimensions, and number of sheets. |
| β Certificate of Origin (CO) | βοΈ | To prove origin for tariff calculation. |
| β Non-Recorded Media Declaration | βοΈ | Critical: State that cards contain NO DATA, are NOT magnetic/optical, and are BLANK. |
β 2. Declaration Tips (Key Mantra)
π₯ "Blank Base, Not Media, Paper or Plastic, Data Free!"
| Scenario | Correct Declaration | Wrong Practice |
|---|---|---|
| Raw paper sheets cut to card size | 4820.10.00.00 "Blank Perforated Paper Stock" |
"Punched Cards" β Might be scrutinized for data security or wrong HS |
| Plastic blanks for ID cards | 3921.90.90.00 "Blank PVC Card Sheets" |
"Computer Media" β Wrong HS, higher risk |
| Cards with data | Do not import as merchandise | Misdeclaring as "blank" β Fraud, seizure, fines |
| Mix of paper and plastic | Split invoices | Single invoice with mixed HS β Confusion, audit risk |
β 3. Special Case Handling
| Scenario | Handling Advice |
|---|---|
| Pre-perforated vs. Plain Sheets | If pre-perforated, use 4820.10.00.00. If plain, use 4802/4803 (different code). Be precise. |
| OEM Custom Sizes | Provide technical drawings to prove it is "paper stock" and not a "finished stationery item" (which might be 4820.10 or 4820.90). |
| Plastic vs. Paper | Misclassifying plastic as paper can lead to 25-30% tariff difference. Always test material if unsure. |
| Data Security Concerns | Even blank cards may be subject to export controls if destined for sensitive entities. Ensure end-user is clean. |

- Consider supply chain diversification (e.g., sourcing from Vietnam or Thailand) to avoid US Section 301 tariffs if exporting to the US.
π VI. Common Errors & Pitfalls Guide (Blood-Tested Lessons)
β Error 1: Declaring "Punched Cards" without specifying "Blank"
π Consequence: Customs may suspect data storage media or spy devices, leading to inspection delays and potential data security audits.
β Error 2: Misclassifying Plastic Card Bases as Paper (4820)
π Consequence: Tariff discrepancy. If plastic is subject to different surtaxes or restrictions, you face back-taxes and penalties.
β Error 3: Using "Computer Accessories" as the Description
π Consequence: Vague description leads to HS Code mismatch. The correct term is "Perforated Paper Stock" or "Blank Card Base."
β Error 4: Ignoring the "Unrecorded" Status
π Consequence: If cards have any print or data, they are not blank media. They become recorded media or printed matter, changing the HS code and tariff rate.
β Correct Practice:
"Blank Perforated Paper Stock, Unpunched, 73x105mm, for Manufacturing Punched Cards, 100% Paper, No Data"
π― VII. Conclusion: Professional Declaration Saves Money!

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
