π© Bolts & Nuts (Fasteners for Iron/Steel)
π HS Code Reference & Clearance Guide | 2026 Latest Tariff Analysis | Strategic Customs Strategy
π 1. Product Definition & Classification: Do You Really Understand "Fasteners"?
Bolts, nuts, and screws are the foundational components of mechanical assembly. In international trade, they are primarily classified under Chapter 73 (Articles of Iron or Steel). Specifically, threaded articles like bolts and nuts fall under heading 7318.
Key Distinction: * Steel/Aluminum/Copper Specific Rules: If the fasteners are made of steel, aluminum, or copper, they may be subject to specific "122 Clause" tariffs and Section 232 tariffs depending on the specific HS code subheading and material composition. * Standard Iron/Steel Fasteners: Generally fall under 7318.15 or 7318.16, with varying tariff impacts based on precise material specifications and standard compliance.
β οΈ Critical Classification Point:
- If the product is a standard iron/steel bolt/nut without specific "steel standard" compliance mentioned in the summary β May fall under 7318.15.20.10/20 (Higher Tax: 85%).
- If the product is a stainless steel or other specific steel nut β May fall under 7318.16.00.60/85 (Lower Tax: 67.5%).
- Do not confuse with non-ferrous or plastic fasteners, which have different HS codes.

π° 3. 2026 Latest Tariff Rate Explanation (Including Surcharges & Policy Add-ons)
β Applicable Country: United States (US)
β Origin: China (CN)
β Effective Time: Current 2026 Tariff Schedule
π― 1. 7318.15.20.10 / 7318.15.20.20 / 7318.15.20.10 (Bolts/Nuts - Standard Steel)
| Item | Content |
|---|---|
| Base Tariff | 0% |
| Additional Tariff | +25% (Section 301 / General Additional) |
| 122 Clause Tariff | +10% (Specific Policy Clause for Steel/Alu/Cu) |
| Steel/Alu/Cu Additional | +50% (Targeted Surcharge on Metallic Products) |
| Total Tax Rate | 85.0% |
| Tax Calculation | CIF Value Γ 85% |
| De Minimis Exemption | β Not Eligible (High risk of seizure if undervalued) |
| Legal Basis Path | HS:7318.15.20.10 β ADD:25% β 122:10% β METAL:50% |
π Explanation:
- The 85% total rate is extremely high, driven by the combination of 25% additional, 10% 122 clause, and 50% metal-specific surcharges.
- This applies to standard iron/steel bolts and nuts (summarized as "Iron/Steel bolts/nuts, threaded articles").
- Compliance is critical: Misclassification can lead to severe penalties.
π― 2. 7318.16.00.60 / 7318.16.00.85 (Nuts - Stainless/Other)
| Item | Content |
|---|---|
| Base Tariff | 0% |
| Additional Tariff | +7.5% (Reduced Additional Surcharge) |
| 122 Clause Tariff | +10% (Same as above) |
| Steel/Alu/Cu Additional | +50% (Same as above) |
| Total Tax Rate | 67.5% |
| Tax Calculation | CIF Value Γ 67.5% |
| De Minimis Exemption | β Not Eligible |
| Legal Basis Path | HS:7318.16.00.60 β ADD:7.5% β 122:10% β METAL:50% |
π Note:
- The 67.5% rate is lower than the 85% rate because the Additional Tariff is only 7.5% instead of 25%.
- This typically applies to stainless steel nuts or other specific steel categories (summarized as "Metal nuts, stainless steel attribute" or "Iron/steel nuts, other categories").
- Even with a lower rate, 67.5% is still very high for fasteners.
π οΈ 4. Customs Clearance Practical Advice (Battle-Tested Pitfall Avoidance Guide)
β 1. Document Checklist (None Can Be Missing)
| Document | Required | Description |
|---|---|---|
| β Product Specification Sheet | βοΈ | Must specify material (e.g., "Stainless Steel 304", "Carbon Steel"), thread type, size, and standard (e.g., ISO, DIN, ASTM). |

| β Country of Origin Certificate | βοΈ | Required for origin determination and tariff application. |
β 2. Declaration Tips (Key Mnemonics)
π₯ "Material Determines Rate, Standard Defines Code, Name Must Be Precise!"
| Scenario | Correct Declaration | Incorrect Practice |
|---|---|---|
| Carbon Steel Bolts | 7318.15.20.10 or 7318.15.20.20 |
Declare as "Metal Fasteners" β Ambiguous β Higher Risk |
| Stainless Steel Nuts | 7318.16.00.60 |
Declare as "Iron Nuts" β Classification Error β Potential Penalty |
| Mixed Shipment (Steel + Stainless) | Separate Line Items | Mixed β Complex Valuation β High Audit Risk |
| Generic "Bolts" | Specify "Iron/Steel" and "Threaded" | Vague Description β Customs Holds Shipment |
β 3. Special Case Handling
| Situation | Handling Advice |
|---|---|
| OEM Custom Fasteners | Provide client order + technical drawing to confirm material and standard. |
| High-Grade Steel | If classified under 7318.15, expect 85% tax. Consider if 7318.16 (if applicable) is a better fit. |
| Small Quantity Samples | Even small shipments are subject to full tariff. De Minimis does not apply. |
| Packaging | Declare fasteners separately from packaging materials to avoid valuation issues. |
π 5. Global Market Clearance Comparison (2026 Latest)
| Country/Region | Recommended HS Code | Tariff Rate | Certification Requirements | Notes |
|---|---|---|---|---|
| πΊπΈ USA | 7318.15.20.10 / 7318.16.00.60 |
67.5% - 85% | None Specific | High Tariff Market due to 122 & Metal Surcharges |
| π¨π³ China | 7318.15 / 7318.16 |
Varies (Lower) | None Specific | Lower tariffs, different classification standards |
| πͺπΊ EU | 7318.15 / 7318.16 |
Varies (0-5%) | CE (if applicable) | No 122 Clause or Metal Surcharge |
| π¨π¦ Canada | 7318.15 / 7318.16 |
Varies | None Specific | CUSMA Benefits if Originating |
| π―π΅ Japan | 7318.15 / 7318.16 |
0% - 3% | PSE (if electrical) | Generally low tariffs |
π Conclusion:
- USA is the most expensive market for steel fasteners due to the cumulative effect of Additional Tariffs (7.5%-25%), 122 Clause (10%), and Metal Surcharges (50%).
- European and Asian markets are significantly more cost-effective for iron/steel fasteners.
- Strategic Advice: Consider supply chain diversification (e.g., sourcing from non-US tariffed countries) for US-bound shipments.
π 6. Common Errors & Pitfall Avoidance Guide (Blood & Tears Lessons)
β Error 1: Declaring "Stainless Steel Nuts" as "Iron Bolts"
π Consequence: Classification Error β Potential fine, audit, or re-classification penalty.
β Error 2: Ignoring the "122 Clause" and "Metal Surcharge"
π Consequence: Unexpected 60%+ additional tax β Profit margin wiped out.
β Error 3: Using vague terms like "Hardware" or "Fasteners"
π Consequence: Customs Delay β Need for clarification, storage fees, and potential demurrage.
β Error 4: Assuming De Minimis Exemption for Small Shipments
π Consequence: Seizure or Forced Repayment β High-value shipments are not exempt.
β Correct Practice:
"Stainless Steel Hex Nuts, M10x1.5, Grade 70, HS 7318.16.00.60"
"Carbon Steel Hex Bolts, Grade 8.8, HS 7318.15.20.10"
π― 7. Conclusion: Precise Classification, Cost Optimization, Smooth Clearance!
π― Remember the Mnemonic:
πΉ "Steel Standard = 85%, Stainless/Other = 67.5%. 122 Clause 10% is Always On. Metal Surcharge 50% is the Killer!"
πΉ "HS Code Defines the Tax, Misclassification Costs More Than Tax!"
π Pro Tip:
If your fasteners are originating from countries with FTAs (e.g., Canada, Mexico, EU), check for preferential tariff treatment. However, note that Section 301 and 232 tariffs may still apply to Chinese-origin goods regardless of FTAs.
Recommend applying for Advance Ruling to confirm the correct HS code and tariff liability before shipment.

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
