🔩 Round Head Screw (Circular Head Screws)
🌐 HS Code Classification & Clearance Guide | 2026 Customs Tariff Analysis | Professional Entry Strategy
📌 One, Product Definition & Classification: Do You Really Understand "Round Head Screws"?
Round head screws (also known as circular head screws) are fasteners characterized by a head that is hemispherical or cylindrical with a rounded top. They are widely used in machinery, automotive, construction, and electronics.
In international trade, the classification hinges on Material and Processing State. Since "Round Head Screw" is a generic term, the HS Code varies significantly based on whether the screw is made of Stainless Steel or Other Iron/Steel (Carbon Steel), and whether it fits specific sub-categories.
⚠️ Key Classification Logic:
- Material Assumption: Based on common industry standards, if not specified, screws are typically Iron/Steel. If specified as "Stainless," it shifts to a different sub-category.
- Shape Feature: "Round Head" falls under the broader category of round-headed fasteners.
- Conflict Check: No material conflict exists if the declaration matches the physical composition.
📦 Two, HS Code Classification Details (2026 Latest Tariff Authority Reference)
Based on the provided data, here are the four most likely HS Codes for Round Head Screws, sorted by material and processing logic:
| HS Code | Product Description & Logic | Material Assumption | Key Feature Match |
|---|---|---|---|
7318.15.20.55 |
Iron/Steel Screws (Round Head) Matches the shape (Round/Loop Head belongs to the round head category) and assumes iron/steel material with no conflict. |
Iron/Steel | High match for standard carbon steel round head screws. |
7318.15.20.51 |
Stainless Steel Screws (Round Head) Matches the shape and assumes Stainless Steel material based on common sense inference. |
Stainless Steel | Specific to stainless steel round head screws. |
7326.19.00.80 |
Other Articles of Iron/Steel Assumes iron/steel; shape is considered a stamped or processed part falling under "Other Iron/Steel Products" (catch-all). |
Iron/Steel | Used if not strictly classified under screws but as a general steel part. |
7326.19.00.10 |
Forged/Stamped Metal Articles Assumes iron/metal; shape is a forged or stamped metal part, fitting the "Other Iron/Steel Products" logic. |
Iron/Steel | Broad classification for forged/stamped steel components. |
🔍 Critical Reminder:
- Stainless vs. Carbon Steel:7318.15.20.51is for Stainless Steel.7318.15.20.55is for Other Iron/Steel (Carbon). Misclassifying carbon steel as stainless (or vice versa) can lead to penalties.
- "Screw" vs. "General Part": If the item is a standard screw, prefer7318.15. If it is a non-standard fastener or industrial stamping part,7326.19may apply as a fallback.

📌 Six, Common Errors & Pitfalls (Lessons Learned)
❌ Error 1: Using a generic HS Code like 7318.15.20.00 (if available) without specifying the sub-code for stainless vs. carbon.
👉 Consequence: Customs will assess at the highest applicable duty or reject the entry.
❌ Error 2: Declaring "Screws" when they are actually "Rivets" or "Nails".
👉 Consequence: Wrong HS Code (7317 vs 7318), leading to 87.9% vs 85.0% difference and potential fraud allegations.
❌ Error 3: Ignoring the "122 Clause" Steel Surcharge.
👉 Consequence: Under-declaring tax. The 50% surcharge is critical for steel products.
✅ Correct Approach:
"Round Head Stainless Steel Screw, Hex Socket, M6x10, Grade 304" →
7318.15.20.51
"Round Head Carbon Steel Screw, Slotted, M6x10, Grade 8.8" →7318.15.20.55
🎯 Seven, Conclusion: Precise Classification, Cost Control!
🎯 Remember the Mantra:
🔹 "Steel Screws to USA: 85% Tax!"
🔹 "Stainless vs Carbon: Check the Spec!"
🔹 "Base 0% + 301 25% + Steel 50% = 85%!"
📌 Pro Tip:
If your volume is large, consider Section 321 De Minimis eligibility (if under $800 per shipment) or look for exclusions from the 122 Clause. Always obtain an Advance Ruling from CBP for new products.

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
