🛢️ Grease Traps (Interceptors) – HS Code & Duty Analysis
🌐 HS Code Reference & Customs Clearance Guide | 2026 Latest Tariff Analysis | Professional Clearance Strategy
📌 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.
⚠️ Key Distinction:
- If made of Iron or Steel → Falls under Chapter 73 (Articles of Iron or Steel).
- If made of Plastics → 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.
📦 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. | 🧱 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). | 🥈 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. | 🧪 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. | 🧱 Cement/Concrete |
🔍 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.
💰 III. 2026 Latest Tariff Rate Breakdown (Including Surcharge Policies)
✅ Applicable Country: USA (US)
✅ Origin: China (CN)
✅ Effective Date: 2025 onwards (Current Trade Policy)
🎯 1. 7324.90.00.00 – Grease Traps (Iron/Steel, Non-Stainless)
| Item | Content |
|---|---|
| Base Tariff | 0.0% (Ad Valorem) |
| Section 301 Surcharge | +25.0% (General steel/iron goods) |
| Steel/Aluminum/Copper Additional Surcharge | +50.0% (Specific to steel products under recent executive orders) |
| Total Tax Rate | 75.0% |
| Tax Calculation | CIF Value × 75% |
| De Minimis Exemption | ❌ Not Eligible |
| Legal Basis | Base Tariff + Section 301 + Steel/Aluminum Surcharge |
📌 Explanation:
- This is the most common classification for heavy-duty metal grease traps.
- The 75% total tariff is extremely high, driven by the 50% steel surcharge on top of the standard 25% Section 301 tariff.
- Cost Impact: For a $10,000 shipment, the duty alone is $7,500.
🎯 2. 7324.10.00.50 – Grease Traps (Stainless Steel)
| Item | Content |
|---|---|
| Base Tariff | 3.4% |
| Section 301 Surcharge | +25.0% |
| Steel/Aluminum/Copper Additional Surcharge | +50.0% |
| Total Tax Rate | 78.4% |
| Tax Calculation | CIF Value × 78.4% |
| De Minimis Exemption | ❌ Not Eligible |
| Legal Basis | Base Tariff + Section 301 + Steel/Aluminum Surcharge |
📌 Explanation:
- Even though stainless steel is more expensive, the surcharge policy is identical to regular steel.
- The higher base rate (3.4% vs 0.0%) makes this category even more expensive than regular iron traps.
🎯 3. 3926.90 – Grease Traps (Plastic)
| Item | Content |
|---|---|
| Base Tariff | Information Not Available in Source Data |
| Total Tax Rate | Error / Failed to Retrieve |
| Tax Calculation | N/A |
| De Minimis Exemption | ⚠️ Check Specific Plastic Rules |
📌 Explanation:
- The source data indicates a failure to retrieve tax information for plastic grease traps.
- Risk: Do not assume zero duty. Plastic goods may still be subject to Section 301 tariffs (often 25%) depending on the specific plastic type and origin.
- Recommendation: Consult a customs broker for the most current HS code detail (e.g., 3926.90.90.80) and applicable duty.

| Tax Calculation | CIF Value × 25% |
| De Minimis Exemption | ❌ Not Eligible |
📌 Explanation:
- Only applicable for large, pre-fabricated concrete interceptors.
- Lower total tariff (25%) compared to steel (75%), but logistics costs for heavy concrete are significantly higher.
🛠️ IV. Customs Clearance Practical Advice (Pitfall Avoidance Guide)
✅ 1. Documentation Checklist (Mandatory)
| Document | Required? | Explanation |
|---|---|---|
| ✅ Product Specification Sheet | ✔️ | Must specify material (Steel, Plastic, Concrete), dimensions, and flow capacity (e.g., GPH - Gallons Per Hour). |
| ✅ Material Certificate | ✔️ | Crucial! Proves whether the item is steel, stainless steel, or plastic. Misclassification here leads to severe penalties. |
| ✅ Commercial Invoice | ✔️ | Must clearly state "Grease Trap" or "Grease Interceptor," NOT generic "Plumbing Fixture." |
| ✅ Packing List | ✔️ | Detail weight and volume (critical for concrete/plastic heavy items). |
| ✅ Photographs | ✔️ | Show the product clearly, including any material stamps or labels. |
✅ 2. Classification Strategy (Key Mantra)
🔥 “Material is King: Steel 75%, Plastic Unknown, Concrete 25%!”
| Scenario | Correct HS Code | Duty Rate | Risk if Misclassified |
|---|---|---|---|
| Heavy Duty Metal Trap | 7324.90.00.00 |
75% | If declared as plastic → Smuggling risk; if declared as concrete → 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. |
✅ 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. |
🌍 V. Global Market Clearance Comparison (2026)
| Country/Region | Recommended HS Code | Estimated Duty (China Origin) | Certification | Notes |

~5-10% | CCC (if applicable) | Lower import duty |
| 🇦🇺 Australia | 7324.90 (Steel) |
~5% | SAA Certification | Low duty, high compliance |
📌 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.
📌 VI. Common Errors & Pitfalls (Lessons Learned)
❌ Error 1: Declaring a Steel Grease Trap as "Plastic Sanitary Ware"
👉 Consequence: Customs audit, penalties, and forced payment of 75% duty + fines.
👉 Why: Material certificates will reveal the truth.
❌ Error 2: Ignoring the Stainless Steel Surcharge
👉 Consequence: Budgeting 25% duty when actual duty is 78.4%.
👉 Why: Stainless steel is still "Steel" under Section 301 and the new 50% surcharge.
❌ Error 3: Assuming Plastic Grease Traps are duty-free
👉 Consequence: Unexpected 25% (or higher) duty if plastic is subject to Section 301.
👉 Why: Plastic goods are not automatically exempt; verification is needed.
✅ Correct Practice:
"Grease Interceptor, Model XYZ, Material: Cast Iron, Capacity: 500 GPH, Weight: 50kg"
🎯 VII. Conclusion: Professional Clearance, Cost Control, Efficiency!
🎯 Remember the Mantra:
🔹 “Steel is 75%, Plastic is Unknown, Concrete is 25%!”
🔹 “Material Certificate is Your Best Friend!”
🔹 “Verify Plastic Duty Before You Ship!”
📌 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.

关于 HS 编码归类
协调制度（HS）是由世界海关组织（WCO）制定的国际贸易商品分类标准。全球 200 多个国家采用 HS 系统作为海关关税、贸易统计和进出口监管的基础。
每个 HS 编码遵循以下层级结构：
- 章（2 位）——商品大类（例如：第 84 章：机器和机械设备）
- 品目（4 位）——章内的更具体分类
- 子目（6 位）——国际通用细分，所有 WCO 成员国统一使用
- 本国细分（8-10 位）——各国自行扩展的细分编码，如美国 HTSUS 10 位编码
正确的 HS 编码归类对于顺利通关、准确缴纳关税和遵守贸易法规至关重要。错误归类可能导致海关延误、多缴关税或罚款。
从CN进口到US时，适用的关税税率可能包括：
- 最惠国（MFN）税率——适用于 WTO 成员国的标准关税税率
- 普通税率——适用于无贸易协定国家
- 贸易救济关税——附加关税，如 301 条款（反倾销）、232 条款（国家安全）或反补贴税
