π HS Code Classification & Customs Clearance Guide for "Copper Threaded Screw" | 2026 Latest Tariff Analysis | Professional Compliance Strategy
π Overview: What is a "Copper Threaded Screw"?
In international trade, a "Copper Threaded Screw" (or Copper Screw Nut/Tap) is a metallic fastener primarily used for securing materials together. Unlike steel or iron screws, copper variants are chosen for their non-magnetic properties, corrosion resistance, and electrical conductivity.
However, the HS Code classification is tricky. It depends entirely on the specific shape (threaded rod vs. nut vs. bolt) and the exact material composition. The data provided highlights a critical divergence: 1. High Tariff Path (88.0%): Classified under Chapter 74 (Copper Works) if strictly defined as copper threads/screws. 2. Lower Tariff Path (37.6%): Classified under Chapter 83 (Miscellaneous Articles of Base Metal) if considered a general "nut" or "closure fitting," often allowing for slightly different tariff treatment.
β οΈ Critical Warning: Misclassification between Chapter 74 and Chapter 83 can result in a 50.4% difference in total duties. This is not just a technicality; it significantly impacts landed cost.
π¦ δΊγHS Code Classification Details (Based on Provided Data)
The following table breaks down the possible HS Codes for "Copper Threaded Screws/Nuts" based on the provided dataset. Note that "Threaded Screw" can be interpreted as a screw, a bolt, or a nut depending on its mating part.
| HS Code | Product Description (Summary) | Key Classification Criteria | Total Tax Rate | Tax Detail Breakdown |
|---|---|---|---|---|
| 7415.33.05.00 | Copper Threaded Screws (Material: Copper; Form: Screw; Use: Fastening) |
Strictly copper fasteners (screws/bolts) under Chapter 74. | 88.0% | Base: 3.0% + Section 301: 25.0% + IEEPA (122 Clause): 10% + 122 Clause Cu/Al: 50% |
| 7415.33.80.10 | Copper Nuts (Material: Copper; Form: Nut; Matches Class Definition) |
Copper nuts specifically defined under Chapter 74. | 88.0% | Base: 3.0% + Section 301: 25.0% + IEEPA (122 Clause): 10% + 122 Clause Cu/Al: 50% |
| 7415.33.80.50 | Copper Nuts (Material: Copper; Form: Nut; Fully Matches Class Requirements) |
Exact match for copper nuts under Chapter 74. | 88.0% | Base: 3.0% + Section 301: 25.0% + IEEPA (122 Clause): 10% + 122 Clause Cu/Al: 50% |
| 8309.90.00.80 | Copper Nuts (Metal Fastening/Sealing Accessory; Matches Material & Use) |
Classified under Chapter 83 (Misc Base Metal Articles). Often used for general "nuts" not strictly defined as copper-specific in Ch 74. | 37.6% | Base: 2.6% + Section 301: 25.0% + IEEPA (122 Clause): 10% (Note: Lower base + no 50% Cu penalty) |
| 8309.90.00.85 | Copper Parts (Stoppers, Caps, Sealings; Similar Metal Fittings) |
Classified as miscellaneous metal closures/accessories under Chapter 83. | 37.6% | Base: 2.6% + Section 301: 25.0% + IEEPA (122 Clause): 10% |
π° δΈγTariff Rate Detailed Explanation (The 50.4% Gap)
Why is there such a huge difference between 88.0% and 37.6%?
π― 1. The "Heavy Tax" Path: 7415.33.xxxx (Total: 88.0%)
| Item | Rate | Source/Legal Basis |
|---|---|---|
| Base Duty | 3.0% | Standard MFN rate for copper articles |
| Section 301 Duty | 25.0% | US Trade Act Section 301 (China Origin) |
| IEEPA Section 122 | 10.0% | International Emergency Economic Powers Act |
| Special Cu/Al Surcharge | 50.0% | Specific 122 Clause for Steel, Aluminum, & Copper Products |
| Total | 88.0% | Extremely High |
π Explanation:
The 50% surcharge is the killer here. This is a specific punitive tariff on copper products under the 122 Clause. If your copper screw is classified under Chapter 74 (which explicitly deals with copper articles), you hit this 50% penalty.
Result: For every $100 of value, you pay $88 in duties.
π― 2. The "Optimized" Path: 8309.90.00.xx (Total: 37.6%)
| Item | Rate | Source/Legal Basis |
|---|---|---|
| Base Duty | 2.6% | Standard rate for miscellaneous base metal articles (Chapter 83) |
| Section 301 Duty | 25.0% | US Trade Act Section 301 (China Origin) |
| IEEPA Section 122 | 10.0% | International Emergency Economic Powers Act |
| Special Cu/Al Surcharge | 0% | Not applicable under Chapter 83 in this context |
| Total | 37.6% | Significant Savings |
π Explanation:
By classifying the item as a "miscellaneous metal fitting" or "closure accessory" under Chapter 83, you avoid the 50% copper-specific surcharge.
Result: For every $100 of value, you pay $37.60 in duties.
Savings: $50.40 per $100 (a 57% reduction in duty costs).β οΈ Risk: You must ensure the product description and commercial invoice clearly support the Chapter 83 classification (e.g., "Metal Closure Fittings" rather than "Copper Screws"). Misrepresentation can lead to audits, penalties, and retroactive duties.
π οΈ εγCustoms Clearance Practical Advice (Avoiding Pitfalls)
β 1. Documentation Checklist (Essential)
| Document | Required? | Purpose |
|---|---|---|
| Commercial Invoice | β Yes | Must specify material (Copper) and form (Screw/Nut/Fitting). Avoid ambiguous terms. |
| Product Specifications | β Yes | Detailed dimensions, thread type (UNC/UNF/Metric), and copper alloy composition. |
| Photo of Product | β Yes | Show the item clearly. If it looks like a generic nut, support Chapter 83. |
| Certificate of Origin | β Yes | Essential for applying Section 301 and IEEPA rates. |
| Packaging List | β Yes | Confirm quantities and weights. |
β 2. Classification Strategy & Naming
| Scenario | Recommended HS Code | Naming on Invoice | Rationale |
|---|---|---|---|
| Strict Copper Screw | 7415.33.05.00 |
"Copper Threaded Screw, Alloy C110" | If the product is undeniably a screw under Ch 74 definitions. |
| General Copper Nut | 7415.33.80.10 / 80.50 |
"Copper Nut, Fastener" | High risk of 88% duty. |
| Metal Fitting/Nut | 8309.90.00.80 |
"Metal Closure Fitting, Copper-Finished" | Lower Duty (37.6%). Use if the item is a general fastener/accessory. |
| Sealing/Closure Part | 8309.90.00.85 |
"Copper Plated Metal Stopper" | Lower Duty (37.6%). Use if the item serves a sealing/closure function. |
π₯ Pro Tip:
If your copper screws are also used for sealing or as closures (e.g., in plumbing or electrical conduits), consider using8309.90.00.80or85. However, you must justify this with the product's primary function and marketing description.
β 3. Common Mistakes & How to Avoid Them
| Mistake | Consequence | Solution |
|---|---|---|
| Using "Copper Screw" on Invoice | Triggers Chapter 74 β 88% Duty | Use broader terms like "Metal Fastener" or "Copper Fitting" if legally permissible. |
| Ignoring IEEPA 122 Clause | Underpayment of duties β Penalties & Retroactive Charges | Always calculate both 301 and 122 tariffs. |
| Assuming All Copper Items are Ch 74 | Misses savings under Ch 83 | Review HS Code notes. Chapter 83 covers "miscellaneous articles" which can include metal fittings. |
| No Material Declaration | Customs may assign higher default rate | Clearly state "Copper Alloy" in specs. |
π δΊγGlobal Market Comparison (Quick Reference)
| Country | Recommended HS Code | Est. Duty Rate | Notes |

37.6% | Optimize by using Chapter 83 if applicable. Avoid Ch 74 if possible. |
| πΊπΈ USA | 7415.33.05.00 |
88.0% | High cost. Only use if Ch 83 is not legally defensible. |
| πͺπΊ EU | 7415.33 |
~5-10% | EU does not have the 122 Clause punitive tariffs. |
| π¨π³ China | 7415.33 |
~3-5% | Low import duty. |
π Conclusion for USA Importers:
The US market is the most challenging due to the 122 Clause.
Action Item: Work with a customs broker to evaluate if your specific "Copper Threaded Screw" can be classified under 8309.90 (Miscellaneous Base Metal Articles) to save 50.4% in duties. Do not simply use the most literal translation of "Copper Screw" if a broader, compliant category exists.

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
