🧪 Copper Pipe Cleaner (Copper Tube Cleaner)
🌐 HS Code Reference & Customs Clearance Guide | 2026 Latest Tariff Analysis | Professional Clearance Strategy
📌 I. Product Definition & Classification: What Exactly is "Copper Pipe Cleaner"?
Copper Pipe Cleaner is a specialized chemical or mechanical product used to remove oxidation, scale, and debris from copper tubing during plumbing or HVAC installation. In international trade, its classification depends heavily on its physical form and chemical composition:
Chemical Cleaners: Liquid or paste formulations containing organic solvents, acids, or surfactants designed to dissolve oxides. Mechanical Cleaners: Solid copper-based brushes, scrubbers, or polishing pads used for physical abrasion.
⚠️ Critical Distinction:
- If the product is a liquid/paste solvent or chemical agent → It is classified under Chapter 38 or Chapter 34 (Chemical Preparations).
- If the product is a solid copper tool/brush intended for scrubbing → It is classified under Chapter 74 (Copper Articles).
📦 II. HS Code Classification Details (2026 Latest Tariff Authority Comparison)
| HS Code | Product Description | Usage Scenario | Key Identification Feature |
|---|---|---|---|
7418.10.00.04 |
Copper scouring or polishing pads, brushes, gloves, etc. | Mechanical cleaning of copper pipes; physical abrasion tools | ✅ Material is Copper |
3814.00.10.00 |
Organic solvents and preparations therefor, containing halogenated derivatives, other | Chemical cleaner containing organic solvents; degreasing/cleaning agents | ✅ Contains Organic Solvents |
3402.90.50.30 |
Preparations for cleaning the skin... other; other prepared laundry or cleaning preparations | General-purpose copper pipe cleaning; non-solvent based cleaning agents | ✅ Classified as Cleaning Preparation |
3402.90.10.00 |
Other surface-active agents (prepared); other preparations for washing, cleaning... | Synthetic detergents/cleaners for copper pipes; surfactant-based formulas | ✅ Classified as Synthetic Cleaner |
7418.10.00.02 |
Copper scouring or polishing pads, brushes, gloves, etc. | Mechanical cleaning tools (similar to .04 but potentially different sub-classification for pads) | ✅ Material is Copper |
🔍 Key Reminder:
- Chemical vs. Mechanical: This is the biggest pitfall. A "cleaner" that is a liquid goes to Chapter 34/38. A "cleaner" that is a copper wire brush goes to Chapter 74. - Solvent Content: If the liquid contains significant organic solvents (beyond standard detergents), it often falls under 3814 (Solvents/Preparations) rather than standard detergents (3402).

- If your product is a liquid chemical cleaner, aiming for 3402 or 3814 is crucial to avoid the 70.5% duty. - 3402 offers the lowest total tax burden (~38.7-38.8%). - 3814 is higher (41.5%) due to higher base rates for solvents.
🛠️ IV. Customs Clearance Practical Advice (Real-World Pitfall Guide)
✅ 1. Preparation Material Checklist (All Required)
| Document | Mandatory | Description |
|---|---|---|
| ✅ Product Specification Sheet | ✔️ | Must clearly state active ingredients, pH level, and physical state (Liquid/Paste/Solid). |
| ✅ MSDS (Material Safety Data Sheet) | ✔️ | Critical for Chapter 34/38. Proves chemical composition. If it contains organic solvents, it supports 3814. If it’s a mild surfactant, it supports 3402. |
| ✅ Product Photos (Clear Label) | ✔️ | Show the bottle, label, and brand. Ensure no misleading images of "copper brushes" if it’s a liquid. |
| ✅ Commercial Invoice | ✔️ | Description must be precise: "Liquid Copper Pipe Cleaner" vs. "Copper Cleaning Brush". |
| ✅ Packing List | ✔️ | Confirm net/gross weight. |
| ✅ Certification (if applicable) | ✔️ | EPA Registration (for US market cleaning agents), NSF/ANSI 61 (if for potable water). |
✅ 2. Declaration Tips (Key Mnemonic)
🔥 “Liquid Chemical, Chapter 34/38. Solid Copper Tool, Chapter 74. Choose 3402 to Save 30%!”
| Scenario | Correct Declaration | Incorrect Practice |
|---|---|---|
| Liquid Cleaner (Mild) | 3402.90.10.00 or 3402.90.50.30 |
Misdeclaring as Copper Tool → 70.5% Duty |
| Liquid Cleaner (Solvent-Based) | 3814.00.10.00 |
Misdeclaring as Simple Detergent → Potential Audit |
| Copper Wire Brush | 7418.10.00.04 or 7418.10.00.02 |
Misdeclaring as Chemical → Rejection/Fine |
| Combo Kit (Liquid + Brush) | Split Declaration | Combined Declaration → Classification Error |
✅ 3. Special Handling Cases
| Situation | Handling Advice |
|---|---|
| Combo Kits (Liquid + Copper Brush) | Do NOT combine. Declare the liquid under 3402/3814 and the brush under 7418. Mixing them leads to misclassification of both. |
| EPA Registered Cleaners | Ensure the EPA Registration Number is on the label. US Customs and EPA may cross-check. |
| "Copper" in Name | Even if named "Copper Cleaner," if it’s a liquid, it’s not Chapter 74. Name alone doesn’t determine HS Code. |
| Origin Marking | Ensure product and packaging are marked "Made in China" to avoid origin fraud issues, which trigger higher penalties. |

📌 VI. Common Errors & Pitfall Guide (Blood & Tears Lessons)
❌ Mistake 1: Declaring a Liquid Copper Cleaner as 7418 (Copper Tool)
👉 Consequence: Pay 70.5% duty instead of 38.7%. Overpayment of 31.8% on CIF value!
❌ Mistake 2: Declaring a Copper Wire Brush as 3402 (Chemical)
👉 Consequence: Customs audit for chemical safety (MSDS required), delays, potential fines for misdeclaration.
❌ Mistake 3: Combining Liquid + Brush in one SKU without splitting
👉 Consequence: Customs will either reclassify the whole kit based on the "essential character" (often the brush) leading to 70.5%, or request separate declarations, causing clearance delays.
❌ Mistake 4: Ignoring EPA Registration for US Market
👉 Consequence: Goods detained by EPA/CBP for unregistered cleaning agents. Return or Destroy.
✅ Correct Approach:
“Liquid Copper Pipe Descaler, Organic Solvent Base, EPA Reg No: XXX-XXX, Net Vol: 500ml” →
3814.00.10.00
OR
“Prepared Laundry/Cleaning Preparation, Surfactant Based, for Copper Pipe Cleaning” →3402.90.50.30
🎯 VII. Conclusion: Professional Declaration, Save Time, Save Money!
🎯 Remember the Mantra:
🔹 "Liquid is Chemical (34/38), Solid is Copper (74)."
🔹 "3402 is the King of Savings (38.8%), 7418 is the Cost Killer (70.5%)."
🔹 "EPA and MSDS are Mandatory for Liquids in the US."

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
