π οΈ Black Self-Tapping Screws (of Iron or Steel)
π HS Code Reference & Customs Clearance Guide | 2026 Latest Tariff Analysis | Professional Strategy for Small Fasteners
π I. Product Definition and Classification: What Are "Black Self-Tapping Screws"?
"Black Self-Tapping Screws" are a specific type of fastener made of iron or steel, characterized by: 1. Material: Iron or steel (typically low-carbon steel). 2. Function: Self-tapping (cut their own thread into the material without a pre-tapped hole). 3. Finish: "Black" refers to the surface treatment (usually black oxide, phosphating, or bluing) for corrosion resistance and aesthetics.
π Key Classification Factor: Shank/Thread Diameter
In international trade (and specifically under HS Code 7318.14), the diameter is the single most critical factor determining the HS Code and, consequently, the tariff rate.
β οΈ Critical Distinction:
- Diameter < 6 mm: Falls under HS Code 7318.14.10.60
- Diameter β₯ 6 mm: Falls under HS Code 7318.14.50.80
π¦ II. HS Code Classification Details (2026 Latest Tariff)
| HS Code | Product Description | Applicable Scenario | Diameter Requirement |
|---|---|---|---|
7318.14.10.60 |
Self-tapping screws: Having shanks or threads with a diameter of less than 6 mm | Small screws for electronics, thin sheet metal, small assemblies, DIY hardware | < 6 mm |
7318.14.50.80 |
Self-tapping screws: Having shanks or threads with a diameter of 6 mm or more | Larger structural screws, furniture assembly, automotive brackets, heavy-duty fasteners | β₯ 6 mm |
π Important Note:
- The term "Black" (color/treatment) does not change the HS Code. It is considered a minor detail in classification. - The distinction is strictly based on the shank or thread diameter. - Both codes fall under the broader category: "Screws, bolts, nuts... of iron or steel: Threaded articles: Self-tapping screws".
π° III. 2026 Latest Tariff Rate Breakdown (Detailed Tax Analysis)

π οΈ IV. Customs Clearance Practical Advice (Avoid Pitfalls)
β 1. Preparation Checklist (Must-Haves)
| Document/Info | Required? | Description |
|---|---|---|
| β Product Specifications | βοΈ | Must clearly state: Material (Steel/Iron), Type (Self-tapping), Diameter (e.g., #8, #10, M4, M6), Length, and Finish (Black Oxide/Phosphate). |
| β HS Code Declaration | βοΈ | Specify whether diameter is < 6mm or β₯ 6mm. Misclassification leads to penalties. |
| β Commercial Invoice | βοΈ | Clearly describe as "Black Self-Tapping Screws, Steel". Do not just write "Screws". |
| β Packing List | βοΈ | Show quantity and weight. |
| β Proof of Origin | βοΈ | If not from China, provide Certificate of Origin to check for lower rates (e.g., from Vietnam, Mexico, etc.). |
β 2. Declaration Tips (Key Mantras)
π₯ "Size is Key! Check Diameter First! 6mm is the Line!"
| Scenario | Correct Declaration | Incorrect Practice |
|---|---|---|
| Small Screws (e.g., #4, #6, #8, M2-M4) | HS: 7318.14.10.60Desc: "Self-tapping screws, steel, diameter < 6mm" |
Misclassifying as β₯ 6mm β No harm, but unnecessary paperwork. |
| Large Screws (e.g., #10, #12, M5-M8+) | HS: 7318.14.50.80Desc: "Self-tapping screws, steel, diameter β₯ 6mm" |
Misclassifying as < 6mm β Customs will reclassify and charge 50% + penalties. |
| Mixed Sizes | Must Split! Declare < 6mm and β₯ 6mm separately. | Mixing in one line item β Risk of seizure or audit. |
β 3. Special Cases & Mitigation
| Situation | Handling Advice |
|---|---|
| Non-China Origin | If screws are made in Vietnam, Mexico, or Thailand, you may qualify for 0% additional tariff. Provide a valid Certificate of Origin. |
| Non-Steel Materials | If made of Stainless Steel, Brass, or Plastic, HS Code and Tax Rate change completely. Ensure material is confirmed as "Iron or Steel". |
| "Black" Coating | Ensure the coating is not a separate component (e.g., plastic housing). It is just a surface treatment, so it does not change classification. |
π V. Global Market Comparison (2026)
| Country/Region | Recommended HS Code | Tariff Rate (China Origin) | Notes |
|---|---|---|---|
| πΊπΈ USA | 7318.14.10.60 / 7318.14.50.80 |
50% | High barrier due to steel tariffs. |
| π¨π³ China | 7318.14.10 / 7318.14.50 |
Low (0-5%) | Domestic trade or export from China. |
| πͺπΊ EU | 7318.14.10 / 7318.14.50 |
0-5% | No additional US-style tariffs. |
| π¬π§ UK | 7318.14.10 / 7318.14.50 |
0-5% | Post-Brexit trade terms apply. |
π Conclusion:
- USA is the most difficult market for Chinese-made steel fasteners due to the 50% additional tariff. - Cost Optimization: Consider sourcing from non-China origins if possible to avoid the 50% surcharge.
π VI. Common Mistakes & Pitfalls
β Mistake 1: Ignoring the 6mm diameter threshold.
π Consequence: If you declare a 7mm screw as "< 6mm", Customs will reclassify it, charge the correct duty, and may impose penalties for misdeclaration.
β Mistake 2: Assuming "Black" implies a different HS Code.
π Consequence: "Black" is a cosmetic feature. It does not change the HS Code. Stick to the diameter.
β Mistake 3: Not specifying "Self-Tapping".
π Consequence: If you just say "Screw", Customs may classify it under general screws (e.g., 7318.15), which might have different duties or require more documentation.
β Mistake 4: Assuming De Minimis ($800) exemption applies.
π Consequence: No. The 50% tariff applies to all shipments from China, regardless of value. Small packages are not exempt.
π― VII. Conclusion: Professional Declaration, Save Money!
π― Remember the Mantra:
πΉ "Check Diameter! <6mm is 7318.14.10, β₯6mm is 7318.14.50."
πΉ "Steel from China? Expect 50% Duty. No Exemptions!"
πΉ "Black is Just Color. Size is the Law."
π Pro Tip:
If you are importing into the USA, calculate the 50% duty into your cost structure from the beginning.
Consider supplier diversification (e.g., source from Vietnam or Mexico) if the 50% tariff makes your product uncompetitive.
π£ Immediate Action:
π Verify the exact diameter of your screws (use calipers if unsure).
π Prepare precise descriptions mentioning "Iron or Steel, Self-Tapping, Diameter [X] mm".
π Avoid customs delays by getting accurate HS Code pre-rulings if you are unsure.
β¨ Professional clearance starts with accurate classification!
πΌ Every percentage point of tariff counts!

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
