π οΈ Grease Trap Screen (Oil-Separation & Filtration Screens)
π HS Code Reference & Customs Clearance Guide | 2026 Tax Rate Analysis | Professional Clearance Strategy
π I. Product Definition & Classification: Do You Really Know "Grease Trap Screen"?
Grease Trap Screens are specialized filtration components used in plumbing and industrial wastewater systems to capture grease, fats, and oils (FOG) before they enter the main sewer lines. They are critical for preventing clogs and environmental contamination.
In international trade, these screens are classified based on material and function:
- Functional Classification (Oil-Separation Equipment): If the item is the primary apparatus designed to separate oil from water, it may fall under 8421.29.
- Parts Classification: If it is a replaceable component (screen mesh, basket, or cage) sold separately for an existing machine, it falls under 8421.99.
- Material Classification (Wire Mesh): If the item is a standalone woven wire mesh (often used as the screen element itself) made of stainless steel, it may be classified under 7314 (Woven cloth of metal).
β οΈ Critical Distinction:
- As a Complete Apparatus: "Grease Trap with Screen" β 8421.29 (Machine).
- As a Replacement Part: "Screen Basket for Grease Trap" β 8421.99 (Part).
- As a Raw Material/Mesh: "Stainless Steel Wire Mesh (Finer than 36 wires/cm)" β 7314.14 (High Tariff Risk).
π¦ II. HS Code Classification Detail (2026 Tax Regime)
Based on your specific dataset, here are the applicable codes and why they apply:
| HS Code | Product Description | Why it fits "Grease Trap Screen" |
|---|---|---|
| 8421.29.00.15 | Filtering or purifying machinery for liquids: Other: Oil-separation equipment | β Applies if the "screen" is part of the main oil-separation unit or the unit itself is classified as "Oil-separation equipment." |
| 8421.99.01.80 | Parts of filtering machinery: Other Other | β Applies if it is a replacement screen, basket, or filter element sold separately for the grease trap machine. |
| 7314.14.90.00 | Woven cloth of stainless steel: With meshes finer than 36 wires/cm | β Applies if the "screen" is a standalone wire mesh made of stainless steel with very fine mesh (high filtration), NOT installed in a machine. |
| 7314.19.01.00 | Woven cloth of iron/steel: Other | β Applies if the screen is woven wire mesh but does not meet the "finer than 36 wires/cm" criteria or is made of non-stainless steel. |
| 3926.90.45.90 | Other articles of plastics: Gaskets, washers, seals | β οΈ Rarely applies. Only if the "screen" includes a plastic sealing ring or gasket as the primary component (unlikely for the screen itself). |
| 3926.30.50.00 | Fittings for furniture, coachwork: Other | β Do Not Use. This is for plastic furniture parts, not industrial filtration screens. |
π Focus on the Top 4:
The most relevant codes for a "Grease Trap Screen" are 8421.29.00.15 (Machine/Assembly), 8421.99.01.80 (Part), or 7314 series (if sold as raw mesh).
π° III. 2026 Tax Rate Breakdown (Detailed & Dangerous)
β Origin: China (CN)
β Market: United States (US)
β Time: 2025/2026 Import Regime
β οΈ Note: Steel/Aluminum/Copper products attract a 50% surcharge on top of the 25% Section 301 tariff.
π― 1. 8421.29.00.15 (Oil-Separation Equipment) & 8421.99.01.80 (Parts)
These are Machinery products.
| Item | Content |
|---|---|
| Base Tariff | 0.0% |
| Section 301 (Add-on) | +25.0% |
| Steel/Al/Cu Surcharge | β Not Applicable (Machinery is not raw steel/copper) |
| Total Tax Rate | 25.0% |
| Tax Calculation | CIF Value Γ 25% |
| Legal Basis | USITC 8421.29 / 8421.99 + Section 301 (301 List) |
π Explanation:
- Machinery (even if made of steel) generally falls under the standard 25% China Section 301 tariff.
- NO additional 50% "Steel Surcharge" applies here.
- Total = 25%.
π― 2. 7314.14.90.00 (Stainless Steel Woven Cloth - Fine Mesh)
This is a Steel/Metal Product with a 50% surcharge.
| Item | Content |
|---|---|
| Base Tariff | 0.0% |
| Section 301 (Add-on) | +25.0% |
| Steel Surcharge | +50.0% (Specific to Steel/Al/Cu products) |
| Total Tax Rate | 75.0% |
| Tax Calculation | CIF Value Γ 75% |
| Legal Basis | USITC 7314 + Steel 232 Tariff + Section 301 |
π Critical Warning:
- If your "Grease Trap Screen" is classified as Woven Wire Mesh (7314), you face a 75% total tariff!
- Why 50%? The US adds a 50% "Steel Surcharge" on top of the 25% Section 301 for steel products.
- Result: 0% + 25% + 50% = 75%.
- Strategy: Avoid classifying as 7314 if possible. Always try to classify as a Part of Machinery (8421) to keep it at 25%.
π― 3. 7314.19.01.00 (Woven Cloth - Other)
Also a Steel/Metal Product.
| Item | Content |
|---|---|
| Base Tariff | 0.0% |
| Section 301 (Add-on) | +25.0% |
| Steel Surcharge | +50.0% |
| Total Tax Rate | 75.0% |
| Tax Calculation | CIF Value Γ 75% |
π Note: Same high-risk scenario as
7314.14. Avoid this classification for screens unless they are strictly raw wire cloth.
π― 4. 3926.90.45.90 (Plastic Gaskets/Seals)
Only if the product includes significant plastic seals.
| Item | Content |
|---|---|
| Base Tariff | 3.5% |
| Section 301 (Add-on) | +25.0% |
| Total Tax Rate | 28.5% |
| Tax Calculation | CIF Value Γ 28.5% |
π Note: If the screen is plastic (unlikely for grease traps) or sold with a heavy plastic seal, this applies. 28.5% is slightly higher than machinery (25%) but much lower than steel mesh (75%).
π οΈ IV. Customs Clearance Practical Advice (Avoid the 75% Trap!)
β 1. Preparation Checklist (Crucial for 7314 vs 8421)
| Document | Must Provide | Why? |
|---|---|---|
| Product Specs | βοΈ YES | Must clearly state: "Screen for Grease Trap" or "Oil Separation Part." |
| Diagram/Assembly | βοΈ YES | Critical! Show that the mesh is a part of a machine. This proves it is 8421, not 7314. |
| Bill of Materials | βοΈ YES | List the mesh as "Filter Element," not "Wire Cloth." |
| Commercial Invoice | βοΈ YES | Description: "Grease Trap Filter Screen (Part)" NOT "Stainless Steel Wire Mesh." |
| Photographs | βοΈ YES | Show the screen inside the housing or as a finished part. |
β 2. Declaration Strategy (Key Mantra)
π₯ "Declare as Part, Not as Cloth! Avoid the 50% Steel Surcharge!"
| Scenario | Correct Declaration | Incorrect Declaration | Tax Rate |
|---|---|---|---|
| Screen as a replaceable part | 8421.99.01.80 (Part of Machinery) |
7314.14.90.00 (Wire Mesh) |
25% vs 75% |
| Complete Grease Trap Unit | 8421.29.00.15 (Machine) |
7314 (Material) |
25% vs 75% |
| Raw Wire Mesh (Standalone) | 7314.14.90.00 (No choice) |
8421 (Misclassification) |
75% (High Risk) |
β οΈ The 75% Risk: If you describe your product as "Stainless Steel Mesh for Filters" without linking it to a machine, US Customs may classify it under 7314, triggering the 50% Steel Surcharge + 25% Section 301 = 75%.
β 3. Special Handling for "Grease Trap Screen"
| Situation | Action |
|---|---|
| OEM/Custom Part | Provide the original machine's HS Code to prove it is a "Part." Use 8421.99. |
| Stainless Steel Mesh | Do NOT use keywords like "Wire Cloth," "Grid," or "Screen Cloth" in the commercial invoice. Use "Filter Element," "Basket," or "Sieve." |
| Plastic Seals | If the screen has a rubber/plastic frame, the whole unit might be considered an assembly. Still aim for 8421. |
π V. Global Market Comparison (2026)
| Country | Recommended HS Code | Tariff | Note |
|---|---|---|---|
| πΊπΈ USA | 8421.99.01.80 |
25% | Avoid 7314 (75% tax). |
| π¨π³ China | 8421.29.00.15 |
0-5% | Domestic duty low. |
| πͺπΊ EU | 8421.29 |
~4-6% | Usually lower than US steel surcharge. |
| π―π΅ Japan | 8421.29 |
0-5% | No additional steel surcharge for parts. |
π Conclusion:
The United States is the only market with the "Steel Surcharge" (50%) on woven wire mesh.
Strategy: Always declare as a "Part of Machinery" (8421) to save 50% in taxes!
π VI. Common Mistakes & Pitfalls
β Mistake 1: Calling the item "Stainless Steel Wire Mesh" on the invoice.
π Result: Customs classifies as 7314 β 75% Tax.
π Fix: Call it "Grease Trap Filter Screen" or "Oil Separation Part."
β Mistake 2: Shipping the mesh loose without a machine.
π Result: High risk of 7314 classification.
π Fix: Provide a "Parts Kit" with a manual showing it is for 8421 machinery.
β Mistake 3: Ignoring the "finer than 36 wires" rule.
π Result: If it is finer than 36 wires/cm, it is 7314.14 (75% tax).
π Fix: Ensure the product description emphasizes its function as a filter part, not the material specification.
π― VII. Final Verdict: The 25% vs 75% Battle
π Winning Strategy:
Declare as8421.99.01.80(Part).
Tax: 25% (Save 50% vs 75%!)

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
