🩺 Sanitizer Gaskets & Mechanical Seals (Disinfectors)
🌐 HS Code Reference & Customs Clearance Guide | 2026 Latest Tariff Analysis | Professional Clearance Strategy
📌 I. Product Definition & Classification: Are You Clear on "Sanitizer Gaskets"?
Sanitizer gaskets are critical sealing components used in medical equipment, laboratory instruments, and industrial sterilization devices (autoclaves/disinfectors). In international trade, they are classified under Chapter 84 (Nuclear reactors, boilers, machinery...), specifically as Gaskets and Similar Joints.
The classification hinges on two key factors:
1. Material Composition: Are they made of metal sheeting combined with other materials (e.g., rubber-lined metal) or multiple layers of metal?
2. Packaging: Are they sold individually, or as sets/assortments (dissimilar compositions) packed in pouches/envelopes?
⚠️ Key Distinction Point:
- If they are mechanical seals or gaskets of metal sheeting combined with other material/multi-layer metal → HS 8484.10.00.00
- If they are other gaskets (e.g., pure rubber, non-metal combinations not fitting the above) or sets → HS 8484.90.00.00
📦 II. HS Code Classification Details (2026 Latest Tariff Authority Comparison)
| HS Code | Product Description | Applicable Scenario | Tax Rate (Total) |
|---|---|---|---|
8484.10.00.00 |
Gaskets of metal sheeting combined with other material or of two or more layers of metal; Mechanical seals | Metal gaskets with rubber/cork lining; Multi-layer metal gaskets for high-pressure sterilizers; Mechanical seals for pumps in disinfectors | 27.5% |
8484.90.00.00 |
Other gaskets and similar joints; Sets or assortments of gaskets | Pure rubber/plastic gaskets (not metal-based); Assortments of mixed gaskets in pouches; Other mechanical seals not covered under 8484.10 | 0.0% |
🔍 Critical Reminder:
- Metal-based gaskets (even if combined with rubber) fall under 8484.10.00.00 and attract a 27.5% duty.
- Non-metallic gaskets (pure rubber, silicone, PTFE) or mixed sets fall under 8484.90.00.00 and are Duty-Free (0%).
- Do not misclassify a metal gasket as "other" to save taxes; Customs will inspect material composition.
💰 III. 2026 Latest Tariff Rate Details (Including Surcharges & Policy Add-ons)
✅ Applicable Country: United States (US)
✅ Origin: China (CN)
✅ Effective Date: 2025-11-10 onwards
🎯 1. 8484.10.00.00 —— Gaskets of Metal Sheeting Combined with Other Material / Mechanical Seals

| Item | Content |
|---|---|
| Base Tariff | 0.0% |
| Section 301 Surcharge | 0.0% |
| Total Tariff | 0.0% |
| Calculation | CIF Value × 0% |
| De Minimis Exemption | ✅ Eligible (if under $800) |
| Legal Path | HTSUS:8484.90.00.00 |
📌 Note:
- This code includes gaskets made of non-metallic materials (e.g., silicone, rubber, PTFE) that do not have a metal sheeting base.
- If your sanitizer gaskets are pure silicone or rubber, they likely fall here, enjoying 0% duty.
- Assortments of dissimilar gaskets in pouches also fall here, often duty-free.
🛠️ IV. Customs Clearance Practical Advice (Real-World Pitfall Guide)
✅ 1. Documentation Checklist (Mandatory)
| Document | Required | Explanation |
|---|---|---|
| ✅ Product Specification Sheet | ✔️ | Must specify material composition (e.g., "Stainless Steel with EPDM Rubber Liner" vs. "Pure Silicone") |
| ✅ Material Safety Data Sheet (MSDS) | ✔️ | Proves non-hazardous nature, confirms material type |
| ✅ Product Photos (Close-up) | ✔️ | Show cross-section to prove if metal is present |
| ✅ Commercial Invoice | ✔️ | Clearly state "Gaskets for Medical Disinfectors" |
| ✅ Packing List | ✔️ | Indicate if sold as "Set/Assortment" (critical for 8484.90) |
✅ 2. Declaration Tips (Key Mnemonic)
🔥 "Metal Base? 27.5%. Pure Rubber? 0%. Check the Layers!"
| Scenario | Correct HS Code | Wrong Practice |
|---|---|---|
| Gasket with Metal + Rubber layer | 8484.10.00.00 |
Misdeclare as "Rubber Gasket" → Audit & Penalty |
| Gasket made of Pure Silicone/Rubber | 8484.90.00.00 |
Misdeclare as "Metal Gasket" → Overpay 27.5% |
| Set of mixed gaskets in pouch | 8484.90.00.00 |
Declare individual items separately → Higher Total Duty |
| Mechanical Seal (Metal Face) | 8484.10.00.00 |
Misdeclare as "Parts of Machinery" → Risk of Re-classification |
✅ 3. Special Handling
| Situation | Recommendation |
|---|---|
| OEM Custom Gaskets | Provide design drawings showing material layers; if metal is only a core with rubber coating, still 8484.10 |
| Pure Silicone Gaskets | Emphasize "100% Silicone" in description to qualify for 0% under 8484.90 |
| Assortments in Pouches | Declare as "Assortment of Gaskets" → 8484.90.00.00 → 0% Duty |
| High-Pressure Metal Gaskets | Cannot avoid 8484.10; consider supply chain optimization to absorb 27.5% |

📌 VI. Common Mistakes & Pitfalls (Lessons Learned)
❌ Mistake 1: Declaring a metal-rubber gasket as "Rubber Gasket"
👉 Consequence: Customs audits → Back taxes + 27.5% penalty
❌ Mistake 2: Declaring pure rubber gaskets as "Metal Gaskets"
👉 Consequence: Overpaying 27.5% unnecessarily
❌ Mistake 3: Not specifying material layers in invoice
👉 Consequence: Customs delays for additional inspection
❌ Mistake 4: Separating assortments instead of declaring as a set
👉 Consequence: Loss of 0% duty benefit for 8484.90
✅ Correct Declaration Example:
"Silicone Gaskets for Medical Disinfectors, Pure Silicone, 100%, No Metal Content, HS 8484.90.00.00"
OR
"Stainless Steel Gaskets with EPDM Rubber Liner for Autoclaves, Metal-Combined Gaskets, HS 8484.10.00.00"
🎯 VII. Conclusion: Precision Classification Saves Costs!
🎯 Key Takeaway:
🔹 "Metal Base = 27.5%. Pure Rubber = 0%. Check the Material!"
🔹 "HS Code Determines Tax, Misclassification Means Penalties!"
📌 Pro Tip:
If your gaskets are pure silicone or rubber, ensure your supplier provides a material certificate stating "No Metal Content" to easily clear under 8484.90.00.00 with 0% duty.
For metal gaskets, consider pricing strategies to absorb the 27.5% duty or explore tariff engineering (e.g., redesigning to use non-metal materials if functionally possible).

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
