🪞 Stainless Steel Mirror Screws (20-Piece Set)
🌐 HS Code Reference & Customs Clearance Guide | 2026 Latest Tariff Analysis | Professional Customs Strategy
📌 Part 1: Product Definition & Classification: Do You Really Understand "Mirror Screws"?
Stainless steel mirror screws are specialized fasteners designed for mounting bathroom mirrors, glass displays, and decorative items. In international trade, they are categorized based on material, form, and dimensions. Because "mirror screws" can vary significantly in diameter and head type, they fall under different sub-headings within Chapter 73.
Key Classification Criteria: * Material: Stainless Steel vs. Iron/Steel. * Form: Bolts (with nuts/washers) vs. Screws (threaded directly into wall anchors or self-tapping). * Dimension: Diameter < 6mm vs. Diameter ≥ 6mm. * Head Type: Hexagonal socket (Allen) vs. Standard flat/pan head.
⚠️ Critical Distinction:
- If the screw is Stainless Steel, it generally falls under 7318.15.
- If the screw is Iron/Steel (often plated), it may fall under 7318.14 or 7318.15 depending on specific sub-definitions.
- Diameter matters: Screws under 6mm often have different duty rates than those 6mm and above.
📦 Part 2: HS Code Classification Details (2026 Latest Tariff Authority Comparison)
Based on the provided data, here are the precise classifications for Stainless Steel Mirror Screws, sorted by product characteristics:
| HS Code | Product Description | Applicable Scenario | Total Tax Rate |
|---|---|---|---|
7318.15.20.91 |
Stainless Steel Bolts: Non-specified stainless steel bolts/fasteners, falling under residual categories. | Standard stainless steel mirror screws (bolts) not specifically listed elsewhere; fits the "residual" principle for stainless steel fasteners. | 85.0% |
7318.15.60.70 |
Stainless Steel Screws: Diameter inferred to be less than 6mm. | Small-diameter stainless steel screws (e.g., delicate bathroom hardware). | 91.2% |
7318.15.60.80 |
Iron/Steel Screws: Non-stainless steel threaded products, not specifically hex-head or stainless. | If the product is actually Iron/Steel (not stainless) or if the stainless category has stricter exclusionary notes. | 91.2% |
7318.14.10.60 |
Iron/Steel Screws/Bolts: Standard iron/steel threaded fasteners, no metal/plastic conflict. | General iron/steel screws (often used for mirrors if not explicitly stainless). | 91.2% |
🔍 Important Note:
- Stainless Steel Advantage? Surprisingly, the Stainless Steel Bolt (7318.15.20.91) has a lower total tax rate (85.0%) compared to the Stainless Steel Screw <6mm (7318.15.60.70) which is 91.2%.
- Why? This is due to the Base Tariff. Stainless bolts in this residual category have a 0% base tariff, whereas the sub-6mm screws have a 6.2% base tariff. The additional duties are the same, making the lower base rate significant.
- Material Clarification: Ensure your product is truly Stainless Steel. If it is plated iron, you risk being classified under7318.14.10.60or7318.15.60.80, both of which have higher total taxes.
💰 Part 3: 2026 Latest Tariff Rate Breakdown (Including Additional Duties & Policy Surcharges)
✅ Applicable Country: United States (US)
✅ Origin: China (CN)
✅ Effective Date: November 10, 2025 onwards (including subsequent imports)
🎯 1. 7318.15.20.91 —— Stainless Steel Bolts (Residual Category)
| Item | Content |
|---|---|
| Base Tariff | 0.0% (Ad valorem) |
| USITC Additional Duty (Section 301) | +25.0% |
| 122 Clause Tariff (Steel, Aluminum, Copper) | +50.0% |
| Total Tax Rate | 85.0% |
| Tax Calculation | CIF Value × 85.0% |
| De Minimis Eligibility | ❌ No (Denied for Section 301 & Steel/Aluminum/Copper duties) |
| Legal Basis Path | USITC:7318.15.20.91 → FOOTNOTE:9903.88.01 → IEEPA:9903.01.25 |
📌 Explanation:
- The 0% base tariff makes this the most cost-effective option for stainless steel fasteners, provided they qualify as "bolts" in the residual category.

📌 Explanation:
- If your product is not stainless steel (e.g., plated iron), it falls into these categories.
- The tax rate is identical to the small stainless steel screw (91.2%).
- Caution: Misdeclaring iron screws as stainless steel can lead to customs audits and penalties.
🛠️ Part 4: Customs Clearance Practical Advice (Live Pitfall Avoidance Guide)
✅ 1. Required Documentation Checklist (Non-negotiable)
| Document | Required? | Explanation |
|---|---|---|
| ✅ Product Specification Sheet | ✔️ | Must specify material (e.g., "SS304 Stainless Steel"), diameter, length, head type. |
| ✅ Material Certification | ✔️ | Proof of stainless steel composition to justify the 0% base tariff (if applicable). |
| ✅ Commercial Invoice | ✔️ | Clearly state "Stainless Steel Mirror Screws" and HS Code. |
| ✅ Packing List | ✔️ | Detail the 20-piece set contents (screws, washers, anchors, etc.). |
| ✅ Origin Certificate (CO) | ✔️ | To prove China origin (triggers Section 301 and 122 Clause duties). |
| ✅ Photos of Product | ✔️ | Show markings, material type, and packaging. |
✅ 2. Declaration Strategy (Key Mantra)
🔥 “Material is King, Diameter is Queen, Form Defines Duty!”
| Scenario | Correct Declaration | Incorrect Action |
|---|---|---|
| True Stainless Steel Bolts | 7318.15.20.91 (85.0%) |
Declare as "Screws" → 91.2% (Higher tax) |
| Small Stainless Screws (<6mm) | 7318.15.60.70 (91.2%) |
Declare as "Bolts" → Risk of misclassification penalty |
| Iron/Steel Screws | 7318.14.10.60 (91.2%) |
Declare as "Stainless Steel" → Fraud/Penalty |
| Mixed Set (Screws + Anchors) | Declare as Fastener Set | Split declaration → Each item taxed separately, potentially higher total |
✅ 3. Special Case Handling
| Situation | Handling Advice |
|---|---|
| Kit with Plugs/Anchors | If the kit includes plastic anchors, ensure the primary item is clearly the stainless steel screw. The entire kit is often classified under the main component's HS code. |
| OEM Custom Sizes | Provide detailed drawings. If diameter is exactly 6mm, clarify if it falls under "less than" or "6mm and above" rules in the specific HS subheading. |
| Stainless Steel Grade | Specify SS304, SS316, etc. Some customs officers may question lower-grade "stainless" if not certified, potentially reclassifying to iron/steel. |
| Small Quantity (20 pcs) | Even for small quantities, the De Minimis exemption ($800) does NOT apply because of the Section 301 and Steel/Aluminum/Copper duties. Taxes must be paid regardless of value. |
🌍 Part 5: Global Market Comparison (2026 Latest)
| Country/Region | Recommended HS Code | Estimated Tax (CN Origin) | Certification Requirements | Notes |

📌 Conclusion:
- USA is the most expensive market for stainless steel fasteners due to 85%-91.2% total duties.
- EU/UK/Australia are significantly more favorable, with duties often under 10%.
- Strategy: If selling to the US, price your products accordingly or consider sourcing from countries not subject to Section 301 (though steel/aluminum duties may still apply).
📌 Part 6: Common Errors & Pitfall Guide (Lessons Learned)
❌ Error 1: Assuming "Mirror Screws" are low-value and exempt from tariffs.
👉 Consequence: No de minimis exemption applies due to Section 301 and 122 Clause duties. Taxes are paid on the full value.
❌ Error 2: Misdeclaring Stainless Steel as "Metal Fasteners" to avoid scrutiny.
👉 Consequence: Customs will request material proof. If unable to prove stainless steel, they may reclassify as iron/steel (7318.14.10.60) or impose penalties for misdeclaration.
❌ Error 3: Ignoring the 6mm diameter distinction.
👉 Consequence: If your screws are <6mm, 7318.15.60.70 applies (91.2%), not the 85% bolt rate. Misclassification leads to underpayment and back-taxes.
❌ Error 4: Combining different materials in one HS Code.
👉 Consequence: If the set includes plastic anchors, ensure the primary fastener (screw) determines the classification. Mixed materials may require separate line items.
✅ Correct Practice:
"SS304 Stainless Steel Mirror Screws, Hex Socket, 20-Piece Set, Including Plastic Anchors, Made in China"
🎯 Part 7: Conclusion: Professional Declaration, Save Money, Save Time!
🎯 Remember the Mantra:
🔹 "Stainless Bolts: 85% Tax, Base 0%. Screws <6mm: 91% Tax, Base 6.2%. Iron/Steel: 91% Tax. No De Minimis!"
🔹 "HS Code defines your cost. A 6% base tariff difference means $600 extra per $10,000 shipment!"
📌 Pro Tip:
- If your stainless steel screws are diameter ≥ 6mm, investigate if they qualify for 7318.15.20.91 (85.0%) or a specific bolt code.
- If they are < 6mm, you are stuck with 91.2%.
- Action: For US imports, consider if the profit margin can withstand an 85-91% tariff. If not, explore Third-Country Transshipment (with proper documentation to avoid anti-circumvention laws) or Duty Drawback programs if re-exporting.

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
