π© Copper Screw Cap (Cu Screw Cap)
π HS Code Reference & Customs Clearance Guide | 2026 Latest Tariff Analysis | Professional Entry Strategy
π 1. Product Definition & Classification: What is a "Copper Screw Cap" in International Trade?
Copper screw caps are small, threaded closure components primarily used to seal containers, pipes, or industrial fittings. In international trade, their classification hinges on two main factors: 1. Form/Function: Is it a generic "lid/cap/stopper" (Heading 8309) or a specific "threaded article of copper" (Heading 7415)? 2. Material: Pure copper or copper alloys.
β οΈ Key Classification Conflict:
- If viewed as a generic accessory for closing vessels β Heading 8309 (Lower Tariff)
- If viewed as a specific copper threaded fastener β Heading 7415 (Higher Tariff due to specific material listing)
π¦ 2. HS Code Classification Details (2026 Latest Tariff Authority Cross-Reference)
| HS Code | Product Description | Applicable Scenario | Tariff Category | Total Tax Rate (US/CN Origin) |
|---|---|---|---|---|
8309.90.00.80 |
Closures of base metal (other than steel/aluminum); specifically Copper Lids/Caps | Generic copper screw caps, not specified as "threaded fasteners" in Chapter 74 | Base Metal Articles (83) | 37.6% |
8309.90.00.85 |
Other closures of base metal (non-steel/aluminum), classified under "Other" | Similar to above; fits generic "cap/stopper" morphology without conflict | Base Metal Articles (83) | 37.6% |
7415.33.80.50 |
Articles of Copper: Nuts, bolts, screws, washers, etc.; specifically Threaded Articles | Explicitly copper, threaded, classified under specific copper components | Copper Articles (74) | 88.0% |
7415.33.80.10 |
Articles of Copper: Nuts, bolts, screws, etc.; Threaded Articles | Matches copper material + threaded form; no obvious conflict with 7415 | Copper Articles (74) | 88.0% |
π Critical Note:
- 8309 vs. 7415: The US Customs and Border Protection (CBP) often scrutinizes copper caps. If the cap is functionally a "fastener" (like a nut/bolt variant), it may be pushed to 7415. However, many traders successfully classify them as 8309 (lids/closures) if they are simple screw-on caps for containers. - Tax Disparity: The difference between 37.6% and 88.0% is massive (50.4% difference). Proper classification is critical.

π οΈ 4. Customs Clearance Practical Advice (Real-World Pitfall Guide)
β 1. Documentation Checklist (Non-Negotiable)
| Document | Required | Explanation |
|---|---|---|
| β Product Specification | βοΈ | Must clearly state "Copper Screw Cap," not just "Metal Part." |
| β Function Description | βοΈ | Describe as "closure for containers" (supports 8309) vs. "threaded fastener" (supports 7415). |
| β Material Certification | βοΈ | Proof of copper alloy composition (e.g., C110, C360). |
| β Commercial Invoice | βοΈ | Clearly describe item as "Copper Closure" or "Copper Cap," not "Copper Screw." |
| β Photos | βοΈ | Show threading, shape, and any branding. |
β 2. Declaration Strategy (Key Mantra)
π₯ "Close as Cap, Not as Screw; Avoid 50% Copper Surcharge!"
| Scenario | Correct Declaration | Wrong Approach |
|---|---|---|
| Container Cap | 8309.90.00.80/85 (37.6%) |
Declare as "Copper Screw" β 7415.33.80 (88.0%) |
| Pipe Fitting Cap | 8309.90.00.80/85 (37.6%) |
Declare as "Copper Threaded Article" β 7415.33.80 (88.0%) |
| Bolt/Nut/Cap Hybrid | Evaluate primary function | If itβs just a cap, do NOT use 7415 unless specifically required by CBP |
π Tip:
- If the product is only a cap (not a bolt, nut, or screw), argue for 8309.
- Use terms like "Copper Closure," "Copper Cap," "Copper Stopper" in invoices.
- Avoid terms like "Copper Screw," "Copper Threaded Fastener," unless itβs truly a screw/bolt.
β 3. Special Case Handling
| Case | Handling Advice |
|---|---|
| Mixed Shipment | Separate copper caps (8309) from copper bolts (7415) to avoid confusion. |
| Customs Audit | Provide samples showing the item is a cap (covers an opening) not a screw (threads into a mating part for fastening). |
| Origin Fraud | Ensure origin is correctly declared. Transshipment does NOT exempt from the 50% copper surtax if copper content remains high. |
π 5. Global Market Comparison (2026 Latest)
| Country/Region | Recommended HS Code | Tariff (CN Origin) | Key Certifications | Remarks |

- EU/UK/Australia: Less critical for tariff optimization, but still require accurate material declaration.
π 6. Common Mistakes & Pitfalls (Lessons Learned)
β Mistake 1: Declaring "Copper Screw Cap" as 7415.33.80.50
π Consequence: Pay 88.0% tax instead of 37.6%. Overpayment of 50.4%!
β Mistake 2: Using "Copper Screw" as the product name
π Consequence: CBP assumes itβs a fastener β pushes to 7415 β 88.0% tax.
β Mistake 3: Mixing "Copper Caps" and "Copper Bolts" in one line item
π Consequence: CBP may audit the entire shipment β delays + potential penalties.
β Mistake 4: Ignoring the 50% Copper Surtax
π Consequence: Unexpected 88.0% total tax bill at clearance.
β Correct Practice:
"Copper Screw Closure for Beverage Containers, Model XYZ, Material: C110 Copper, Made in China"
π― 7. Conclusion: Professional Declaration, Save Money, Avoid Delays!
π― Remember the Mantra:
πΉ "Cap = 8309 (37.6%); Screw/Fastener = 7415 (88.0%)."
πΉ "50.4% Tax Savings by Choosing 8309!"
πΉ "Name it 'Cap' or 'Closure,' not 'Screw'!"
π Tip:
- If your copper caps are small, simple, and used as closures, strongly argue for 8309.
- If they are complex, high-torque, or used as mechanical fasteners, CBP may insist on 7415.
- Pre-classification Ruling: Consider applying for a CBP Ruling if shipment value is high.

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
