🌿 Cork Granules (Horticultural Grade)
🌐 HS Code Reference & Customs Clearance Guide | 2026 Latest Tariff Analysis | Professional Import Strategy
📌 1. Product Definition & Classification: What Are Horticultural Cork Granules?
Cork Granules for horticultural use are processed pieces of natural cork (from the bark of the Quercus suber tree), sized typically between 1-5mm or 5-10mm. They are widely used in potting mixes, soil aeration, hydroponics, and as mulch due to their water retention, antibacterial properties, and lightweight nature.
Key Distinction:
- Granules for Horticulture: Used for soil amendment, drainage, or mulching.
- Granules for Industrial/Construction: Used for flooring, insulation, or shock absorption.
⚠️ Critical Classification Point:
- If intended for plant growth, soil improvement, or horticultural applications, they fall under HS 1404.90 (Vegetable products not elsewhere specified or included).
- If used for industrial purposes (e.g., construction materials), they may fall under HS 3918.90 (Plastic flooring, if processed differently) or HS 4421.99 (Other wood articles), but horticultural cork is strictly classified under HS 1404.90.

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
