AI Analysis
🔒 Lock Washers & Seals (锁片/垫片)
🌐 HS Code Reference & Customs Clearance Guide | 2026 Latest Tariff Analysis | Professional Entry Strategy
📌 I. Product Definition & Classification: Are You Classifying "Lock Washers" Correctly?
Lock Washers (Lock Washers/Lock Plates) and Seals (Gaskets, O-Rings) are critical fastening components. In international trade, their classification depends entirely on the material composition and specific function.
Crucial Distinction by Material: 1. Plastic/Non-Metallic Lock Washers & Seals: If the washer is made of plastic or other materials from chapters 3901–3914 (e.g., Nylon, PTFE, Rubber), it falls under Chapter 39. 2. Metal Lock Washers (Iron/Steel): If the washer is made of iron or steel, it falls under Chapter 73.
⚠️ Key Classification Point:
- Plastic/Rubber Seals/Washers → Chapter 39 (3926.90.45)
- Steel/Iron Lock Washers → Chapter 73 (7326.90.86.88 or 7315.11.00)
- Note: While "Lock Washers" are functionally washers, the provided data explicitly links "O-Rings/Seals" to 3926.45, and general "Other articles of iron/steel" to 7326.86.88.
📦 II. HS Code Classification Details (Based on Provided Data)
| HS Code | Product Description | Material Category | Specific Type in Data |
|---|---|---|---|
3926.90.45.10 |
Gaskets, Washers and Other Seals: O-Rings | Plastics/Non-Metals (Ch 3901-3914) | Explicitly lists "O-Rings" |
3926.90.45.90 |
Gaskets, Washers and Other Seals: Other | Plastics/Non-Metals (Ch 3901-3914) | Most likely for "Lock Washers" if plastic |
7326.90.86.88 |
Other Articles of Iron or Steel: Other | Iron/Steel | General metal parts (Lock Washers fit here as "Other") |
7315.11.00 |
Other Articles of Iron or Steel: Forged or Stamped | Iron/Steel | If the lock washer is specifically forged/stamped |
8301.60.00.00 |
Parts of Locks/Base Metal Articles | Base Metal | Only if it is a part of a lock mechanism, not a generic fastener |
🔍 Critical Alert:
- Plastic Lock Washers: Must use 3926.90.45.90 (as "Other" seals/washers).
- Steel Lock Washers: Usually fall under 7326.90.86.88 ("Other") unless specifically forged/stamped (7315.11.00).
- Do NOT classify generic metal lock washers as "Parts of Locks" (8301.60.00.00) unless they are integral to a locking device.

🎯 2. Steel/Iron Lock Washers (7326.90.86.88 & 7315.11.00)
A. 7326.90.86.88 (Other Articles of Iron or Steel)
| Item | Content |
|---|---|
| Base Tariff | 2.9% |
| Section 301 Surcharge | 25.0% |
| Steel/Aluminum/Copper Surcharge | +50% (Specifically for steel products) |
| Total Tax Rate | 77.9% |

B. 7315.11.00 (Forged or Stamped Iron/Steel Articles)
| Item | Content |
|---|---|
| Tax Status | Error |
| Detail | "Failed to retrieve tax information" |
| Risk | ⚠️ Unknown Rate. Assume high risk. May be subject to similar steel surcharges. |
📌 Warning:
- Do not use7315.11.00without confirming the tax rate. If it is subject to steel rules, it could also be ~77.9%.
🎯 3. Parts of Locks (8301.60.00.00)
| Item | Content |
|---|---|
| Tax Status | Error |
| Detail | "Failed to retrieve tax information" |
| Note | Only applicable if the "Lock Washer" is a part of a lock mechanism. |
📌 Caution:
- Misclassifying a generic lock washer as a "part of a lock" is a customs violation risk. Only use this if the product is explicitly sold as a component of a locking system.
🛠️ IV. Customs Clearance Practical Advice (Avoid Pitfalls)
✅ 1. Material Declaration is Key
| Scenario | Correct HS Code | Tax Rate | Why? |
|---|---|---|---|
| Plastic/Nylon Lock Washer | 3926.90.45.90 |
0.0% | Falls under "Other gaskets/washers" of plastics. No steel tax. |
| Steel Lock Washer | 7326.90.86.88 |
77.9% | Subject to Steel Surcharge (50%) + Section 301 (25%) + Base (2.9%). |
| O-Ring (Plastic) | 3926.90.45.10 |
0.0% | Explicitly listed as O-Ring. |
| O-Ring (Rubber) | Not in Data | Unknown | Check if rubber falls under Ch 40 (not provided here). |
🔥 "Material Matters" Rule:
- Plastic/Non-Metal = 0% Tax
- Steel/Iron = ~78% Tax
- Choice: If functionally similar, switch to plastic/nylon to save 77.9% in taxes!
✅ 2. Declaration Tips
| Situation | Correct Declaration | Avoid |
|---|---|---|
| Plastic Washer | "Plastic Lock Washer, Nylon, for Fastening" | "Steel Washer" or "Part of Lock" |
| Steel Washer | "Iron or Steel Lock Washer, Stamped" | "Part of Lock" (unless true) |
| O-Ring | "Plastic O-Ring Seal" | "Gasket" (if O-Ring is specified) |
📌 Accuracy:
- Ensure the Material Composition is clearly stated in the commercial invoice.
- If declaring3926.90.45.90, explicitly state "Plastic" or "Nylon" or "PTFE".
- If declaring7326.90.86.88, expect high tariffs. Consider sourcing from non-China countries to avoid Section 301/Steel Surcharge.
✅ 3. Special Cases
| Situation | Handling Suggestion |
|---|---|
| Mixed Package (Plastic + Steel) | Declare separately. Plastic at 0%, Steel at 77.9%. Do not mix codes. |
| "Lock Washer" vs. "Part of Lock" | If it's a standard automotive/industrial washer, use 7326.90.86.88 or 3926.90.45.90. Do NOT use 8301.60.00.00 unless it's a lock part. |
| Tax Error Codes | If 7315.11.00 or 8301.60.00.00 shows "Error", use the most specific available code (e.g., 7326.90.86.88 for steel, 3926.90.45.90 for plastic). |

📌 VI. Common Mistakes & Pitfalls
❌ Mistake 1: Declaring a Steel Lock Washer as a "Part of a Lock" (8301.60.00.00)
👉 Consequence: Customs may reject or reclassify to 7326.90.86.88 (77.9%) + fines.
❌ Mistake 2: Assuming All Washers are taxed equally
👉 Consequence: Missing the 0% rate for Plastic (3926.90.45.90).
❌ Mistake 3: Ignoring the Steel Surcharge
👉 Consequence: Underestimating cost by 50% for steel products.
✅ Correct Action:
- Use Plastic/Nylon Washers whenever possible to achieve 0% Tax.
- For Steel, budget for 77.9% or source from non-China origins.
- Never misclassify generic washers as "Lock Parts."
🎯 VII. Conclusion: Optimize Your Classification
🎯 Remember:
🔹 "Plastic = 0%, Steel = 78% (in USA)"
🔹 "Washer ≠ Lock Part"
🔹 "Check Material First!"
📌 Pro Tip:
If your product can be made of plastic or steel, choose plastic for US imports to save 77.9% in taxes.
For steel, consider supply chain diversification (e.g., Vietnam, Mexico) to avoid Section 301 and Steel Surcharges.

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
