🌊 4-Piece Washing Machine Drain Connectors (Plumbing Fittings)
🌐 HS Code Reference & Customs Clearance Guide | 2026 Latest Tariff Analysis | Professional Clearance Strategy
📌 I. Product Definition & Classification: What Exactly Are "Drain Connectors"?
Washing machine drain connectors are critical plumbing accessories used to direct wastewater from washing machines to household drainage systems. In international trade, these items are strictly regulated under Chapter 39 (Plastics) or Chapter 73 (Iron/Steel), depending on their material. The key to accurate classification lies in distinguishing between pressure-rated fittings and non-pressure-rated plumbing fittings (DWV - Drain, Waste, Vent).
⚠️ Critical Distinction:
- If the fitting is made of plastics and used for low-pressure drainage (not pressurized water supply) → It falls under 3917.40.00.50.
- If the fitting is made of plastics but is a general-purpose pipe fitting not specifically defined as DWV → It falls under 3917.40.00.80.
- If the fitting is made of iron or steel (e.g., metal couplings, elbows) → It falls under 7307 categories.
- If it is a gasket or seal included in the set (e.g., rubber washers) → It may fall under 3926.90.45.90.
📦 II. HS Code Classification Details (2026 Latest Tariff Authority Comparison)
| HS Code | Product Description | Material | Pressure Rating | Application Scenario |
|---|---|---|---|---|
3917.40.00.50 |
Plumbing fittings, not pressure rated (Drain/Waste/Vent - DWV): Other | Plastics | Non-Pressure | Washing machine drain hoses, flexible PVC connectors |
3917.40.00.80 |
Fittings Other (Plastics): Other | Plastics | Other/Low Pressure | General plastic pipe fittings, elbows, joints not specifically DWV |
7307.19.90.80 |
Cast fittings of iron or steel: Other: Other | Iron/Steel | Varies | Heavy-duty cast iron drain connectors (rare for standard home washers) |
7307.99.50.45 |
Tube or pipe fittings of iron or steel: Other | Iron/Steel | Varies | Steel couplings, elbows, sleeves for industrial plumbing |
3926.90.45.90 |
Gaskets, washers and other seals (Plastics) | Plastics (Seals) | N/A | Rubber/plastic gaskets/seals included in the connector kit |
🔍 Key Reminder:
- Most household washing machine drain connectors are plastic (PVC/PP).
- If they are designed for gravity drainage (not pressurized), they qualify as DWV fittings under 3917.40.00.50.
- Do not misclassify as general hardware unless specified. Incorrect classification can lead to severe penalty taxes.

🛠️ IV. Customs Clearance Practical Advice (Real-World Pitfall Guide)
✅ 1. Documentation Checklist (Essential)
| Document | Required | Purpose |
|---|---|---|
| ✅ Product Specification Sheet | ✔️ | Confirm material (Plastic vs. Steel) and pressure rating (DWV vs. Pressure) |
| ✅ Product Photos (Clear) | ✔️ | Show shape, connections, and any metal components |
| ✅ Commercial Invoice | ✔️ | Describe as "Plastic Washing Machine Drain Connector Set (DWV Fittings)" |
| ✅ Packing List | ✔️ | List quantity (4 pieces) and weight |
| ✅ Certificate of Origin (CO) | ✔️ | To verify origin (China) and apply appropriate surtaxes |
✅ 2. Declaration Tips (Key Mantras)
🔥 "Plastic DWV is Zero Tax, Steel is High Cost, Seals Must Be Included!"
| Situation | Correct Declaration | Incorrect Action |
|---|---|---|
| Plastic washing machine drain connector | 3917.40.00.50 (DWV, Plastic) |
Declare as "Plastic Pipe" generally → Risk of audit |
| Include rubber gaskets in the set | Declare under main fitting code | Separate declaration of gaskets → 28.5% tax |
| Steel connector (if any) | 7307.99.50.45 |
Declare as plastic → Customs fraud/penalty |
| Mixed set (Plastic + Metal) | Declare by principal material or separate | Misclassify metal as plastic → High penalty |
✅ 3. Special Handling
| Scenario | Recommendation |
|---|---|
| OEM Custom Connectors | Provide design drawings to prove DWV functionality |
| With Silicone Gaskets | Ensure gaskets are declared as part of the fitting set, not separately |
| Steel Components | If unavoidable, accept the 25%-79% tax burden; consider switching to plastic |

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
