π’οΈ Grease Traps (Interceptors) β HS Code & Duty Analysis
π HS Code Reference & Customs Clearance Guide | 2026 Latest Tariff Analysis | Professional Clearance Strategy
π I. Product Definition: What Exactly is a "Grease Trap"?
A grease trap (also known as a grease interceptor) is a plumbing device designed to intercept most greases and solids before entering a wastewater disposal system. They are critical components in commercial kitchens, industrial facilities, and food processing plants.
Material Matters:
The classification of a grease trap depends heavily on its primary material of construction. The two most common materials are:
1. Metal (Iron/Steel): Durable, common in heavy-duty commercial settings.
2. Plastic (Polyethylene/PVC): Common in residential or lighter commercial applications.
β οΈ Key Distinction:
- If made of Iron or Steel β Falls under Chapter 73 (Articles of Iron or Steel).
- If made of Plastics β Falls under Chapter 39 (Articles of Plastics).
- Note: There is NO specific HS code solely for "grease traps." They are classified based on their material under the "Other Articles" residual categories.
π¦ II. HS Code Classification Details (2026 Latest Tariff Rules)
| HS Code | Product Description | Applicable Scenario | Material |
|---|---|---|---|
7324.90.00.00 |
Sanitary ware and parts thereof, of iron or steel: Other, including parts | Grease traps made of cast iron or steel, often used in heavy-duty commercial kitchens. | 𧱠Iron/Steel |
7324.10.00.50 |
Sanitary ware and parts thereof, of iron or steel: Sinks and wash basins, of stainless steel: Other | If the grease trap is constructed as a stainless steel unit (often integrated with a sink-like structure). | π₯ Stainless Steel |
3926.90 |
Other articles of plastics | Grease traps made entirely of plastic (e.g., HDPE, PVC). Common in residential or light commercial use. | π§ͺ Plastic |
6810.99.00.80 |
Articles of cement, of concrete or of artificial stone, whether or not reinforced: Other articles: Other | Rare but possible: Large, underground concrete interceptors used in civil engineering. | 𧱠Cement/Concrete |
π Critical Reminder:
- Do NOT assume all grease traps fall under one code.
- Metal traps generally attract higher tariffs due to current trade policies on steel/aluminum.
- Plastic traps may have different duty structures, though data in the source is incomplete for this category.
π° III. 2026 Latest Tariff Rate Breakdown (Including Surcharge Policies)
β Applicable Country: USA (US)
β Origin: China (CN)
β Effective Date: 2025 onwards (Current Trade Policy)
π― 1. 7324.90.00.00 β Grease Traps (Iron/Steel, Non-Stainless)

π οΈ IV. Customs Clearance Practical Advice (Pitfall Avoidance Guide)
β 1. Documentation Checklist (Mandatory)
| Document | Required? | Explanation |
|---|---|---|
| β Product Specification Sheet | βοΈ | Must specify material (Steel, Plastic, Concrete), dimensions, and flow capacity (e.g., GPH - Gallons Per Hour). |
| β Material Certificate | βοΈ | Crucial! Proves whether the item is steel, stainless steel, or plastic. Misclassification here leads to severe penalties. |
| β Commercial Invoice | βοΈ | Must clearly state "Grease Trap" or "Grease Interceptor," NOT generic "Plumbing Fixture." |
| β Packing List | βοΈ | Detail weight and volume (critical for concrete/plastic heavy items). |
| β Photographs | βοΈ | Show the product clearly, including any material stamps or labels. |
β 2. Classification Strategy (Key Mantra)
π₯ βMaterial is King: Steel 75%, Plastic Unknown, Concrete 25%!β
| Scenario | Correct HS Code | Duty Rate | Risk if Misclassified |
|---|---|---|---|
| Heavy Duty Metal Trap | 7324.90.00.00 |
75% | If declared as plastic β Smuggling risk; if declared as concrete β Rejection |
| Stainless Steel Trap | 7324.10.00.50 |
78.4% | Higher base rate makes this the most expensive metal option |
| Plastic Trap | 3926.90 |
Unknown/Error | High risk of under-declaration if assumed low duty. Verify with broker. |
| Concrete Trap | 6810.99.00.80 |
25% | Must be "pre-fabricated" to fit this category. |
β 3. Special Considerations
| Situation | Handling Advice |
|---|---|
| OEM Custom Grease Traps | Provide design drawings to prove the material composition. Custom steel traps are still subject to 75% duty. |
| Mixed Material Traps | If a trap has steel frames and plastic bowls, customs may classify based on the essential character (usually steel frame). Expect 75% duty. |
| Pre-Fabricated Concrete Units | Ensure they are classified as "Prefabricated Structural Components" if they are large civil engineering items. |
| Plastic Trap Duty Uncertainty | DO NOT ASSUME LOW DUTY. Contact your freight forwarder to confirm the current Section 301 applicability for plastic sanitary ware. |
π V. Global Market Clearance Comparison (2026)
| Country/Region | Recommended HS Code | Estimated Duty (China Origin) | Certification | Notes |
|---|---|---|---|---|
| πΊπΈ USA | 7324.90.00.00 (Steel) |
75% | None specific, but ASTM standards apply | Highest duty due to steel surcharge |
| πͺπΊ EU | 7324.90 (Steel) |
~8-10% (Standard MFN) | CE Marking | No Section 301 equivalent |
| π¨π³ China | 7324.90 (Steel) |
~5-10% | CCC (if applicable) | Lower import duty |
| π¦πΊ Australia | 7324.90 (Steel) |
~5% | SAA Certification | Low duty, high compliance |
π Conclusion:
- The USA is the most expensive market for steel grease traps due to the 75% total tariff.
- Plastic alternatives may offer cost savings, but the duty rate is unclear in the source data and must be verified.
- Concrete traps offer a lower duty rate (25%) but have high shipping costs.
π VI. Common Errors & Pitfalls (Lessons Learned)
β Error 1: Declaring a Steel Grease Trap as "Plastic Sanitary Ware"
π Consequence: Customs audit, penalties, and forced payment of 75% duty + fines.
π Why: Material certificates will reveal the truth.
β Error 2: Ignoring the Stainless Steel Surcharge
π Consequence: Budgeting 25% duty when actual duty is 78.4%.
π Why: Stainless steel is still "Steel" under Section 301 and the new 50% surcharge.
β Error 3: Assuming Plastic Grease Traps are duty-free
π Consequence: Unexpected 25% (or higher) duty if plastic is subject to Section 301.
π Why: Plastic goods are not automatically exempt; verification is needed.
β Correct Practice:
"Grease Interceptor, Model XYZ, Material: Cast Iron, Capacity: 500 GPH, Weight: 50kg"
π― VII. Conclusion: Professional Clearance, Cost Control, Efficiency!
π― Remember the Mantra:
πΉ βSteel is 75%, Plastic is Unknown, Concrete is 25%!β
πΉ βMaterial Certificate is Your Best Friend!β
πΉ βVerify Plastic Duty Before You Ship!β
π Pro Tip:
Given the 75% duty on steel grease traps, consider:
1. Supplier Negotiation: Ask suppliers to absorb part of the duty or offer EXW prices to mitigate cost.
2. Alternative Materials: Explore plastic or concrete options if duty savings outweigh logistics costs.
3. Pre-Ruling: Apply for a Binding Tariff Information (BTI) or Ruling from US Customs (CBP) to confirm the exact classification and duty rate for your specific product design.

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
