π 1. Product Definition and Classification: Do You Really Understand "Bamboo Joint Screws"?
Bamboo joint screws, also known as bamboo connector nails, are specialized fasteners designed specifically for assembling bamboo structures, including bamboo furniture, flooring, decking, and architectural bamboo components. These fasteners are typically made from stainless steel or carbon steel with anti-corrosion coatings, and feature unique thread designs to prevent splitting in the brittle bamboo material.
In international trade, they are classified under two main categories based on material and function:
Steel Fasteners for Bamboo: Primarily stainless steel or carbon steel nails/screws for bamboo assembly;
Specialized Bamboo Hardware: Includes bamboo-specific connectors, brackets, and joint systems.
β οΈ Key Distinction:
- If the product is purely a metal screw/nail for bamboo assembly β Classified under 7318.15 or 7318.16
- If the product is a complex bamboo connector system (not just a simple screw) β May fall under 7318.29 or even 4421.90 if considered part of bamboo furniture components

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
