🍷 Cork Wafers (Natural or Agglomerated)
🌐 HS Code Reference & Customs Clearance Guide | 2026 Latest Tariff Analysis | Professional通关 Strategy
📌 1. Product Definition & Classification: Do You Really Understand “Cork Wafers”?
Cork wafers are thin, disc-shaped pieces made from natural cork or agglomerated cork, commonly used in winemaking (as wine stoppers or closures), DIY crafts, and insulation. In international trade, they are classified based on their material composition and processing level.
Key Distinction:
- Natural Cork Wafers: Cut directly from the bark of the cork oak tree (Quercus suber).
- Agglomerated Cork Wafers: Made from cork granules bound together with food-grade or industrial adhesives.
⚠️ Critical Classification Point:
- If the product is natural cork, it falls under Chapter 45 (Cork and articles of cork).
- If it is agglomerated cork (granules + adhesive), it may still fall under Chapter 45 if the cork content is predominant, but some jurisdictions may classify it under Chapter 39 (Plastics) or Chapter 44 (Wood) if adhesives dominate. However, most customs authorities treat agglomerated cork as cork articles if the primary material is cork.

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
