HS Code Classification for "LONG SCREW"
Based on the provided reference data, here's a classification breakdown for "LONG SCREW". It's crucial to confirm the material and specifications to ensure accurate classification.
1. 7318154000 – Screws, bolts, nuts, coach screws, screw hooks, rivets, cotters, cotter pins, washers (including spring washers) and similar articles, of iron or steel: Threaded articles: Other screws and bolts, whether or not with their nuts or washers: Machine screws
- 73: Chapter 73 – Articles of iron or steel. This broadly covers iron and steel products.
- 18: Section 73.18 – Screws, bolts, nuts, coach screws etc. This narrows down the category to fasteners.
- 15: Subsection 73.18.15 – Threaded articles. Specifically focuses on screws and bolts with threads.
-
40: Further specifies "Other screws and bolts" meeting certain length and diameter criteria (>=9.5mm length, >=3.2mm diameter, excluding cap screws).
- Applicability: This is the most likely HS code if the long screw is made of iron or steel, has a length of 9.5mm or more, a diameter of 3.2mm or more, and is not a cap screw.
- Tax Rate: Base Tariff: 0.0%, Additional Tariff: 25.0%, Post 2025.4.2 Additional Tariff: 30% (Steel/Aluminum products 25%). Total Tax Rate: 80.0%.
Important Considerations & Recommendations:
- Material Verification: Confirm the screw's material (iron, steel, or other). If it's not iron or steel, this HS code is incorrect.
- Dimensions: Precisely measure the screw's length and diameter. If either is below the specified thresholds (9.5mm length, 3.2mm diameter), a different HS code will be needed.
- Cap Screw vs. Machine Screw: Determine if the screw is a cap screw. Cap screws often have a different HS code classification.
- Coating: If the screw has a coating (e.g., zinc, nickel), this may affect the classification.
- Certification: Depending on the end-use application, specific certifications (e.g., RoHS, REACH) might be required.
- Single vs. Multiple Components: If the long screw is supplied with nuts and washers, the classification may change.
Disclaimer: This classification is based solely on the provided reference data and the user's input ("LONG SCREW"). A definitive classification requires a complete product specification and potentially a ruling from customs authorities.
