🔌 Hose Connectors (Pipe Fittings)
🌐 HS Code Reference & Customs Clearance Guide | 2026 Latest Tariff Analysis | Professional Level Clearance Strategy
📌 I. Product Definition and Classification: Do You Really Understand "Hose Connectors"?
Hose connectors (also known as pipe fittings or hose nipples) are critical components used to join hoses, pipes, or tubes together. In international trade, they are strictly categorized by material and function. Misclassification can lead to severe tariff penalties, especially under current US-China trade restrictions (Section 301, Section 232, IEEPA).
There are three primary material categories: 1. Iron/Steel (Ferrous): Rugged, high-pressure industrial applications. 2. Plastic (Non-Metallic): Corrosion-resistant, low-pressure fluid/gas transfer. 3. Copper: Plumbing, HVAC, and specific fluid systems.
⚠️ Critical Distinction Point:
- If made of Iron/Steel → Look under Chapter 73 (Articles of Iron or Steel);
- If made of Plastic → Look under Chapter 39 (Plastics and Articles Thereof);
- If made of Copper → Look under Chapter 74 (Copper and Articles Thereof) or Chapter 84 (Machinery/Valves) depending on specific design (valve-like vs. simple connector).
📦 II. HS Code Classification Details (2026 Latest Tariff Authority Comparison)
| HS Code | Product Description | Application Scenario | Material |
|---|---|---|---|
7307.99.50.45 |
Hose connectors of iron or steel, classified under "Other pipe fittings" | General industrial steel hose connectors | ✅ Iron/Steel |
7307.19.90.80 |
Hose connectors of iron or steel, classified under "Other" | Standard steel pipe fittings, non-standard types | ✅ Iron/Steel |
3917.40.00.95 |
Other plastic tube fittings | General plastic hose connectors (not explicitly listed as "attachments") | ✅ Plastic |
3917.40.00.10 |
Plastic hose connectors, explicitly listed as attachments (e.g., elbows, couplings) | Specific plastic fittings designed as attachments | ✅ Plastic |
8481.80.10.50 |
Copper hose connectors, classified as "Valves and similar appliances" | Copper fittings designed with valve-like mechanisms or specific pressure-regulating features | ✅ Copper |
🔍 Key Reminder:
- Iron/Steel items generally fall under 7307. The difference between.50.45and.19.90.80lies in the specific sub-heading nuances of "Other" vs. specific "Pipe Fittings." - Plastic items fall under 3917. The distinction between.95and.10is whether they are explicitly categorized as "attachments" in the tariff schedule. - Copper is tricky. Simple connectors might fall under 7426, but if the connector has valve-like functions or is classified under Chapter 84, it goes to 8481. The provided data specifies 8481.80.10.50.
💰 III. 2026 Latest Tariff Rate Breakdown (Including Surcharge Taxes & Policy Additions)
✅ Applicable Country: United States (US)
✅ Country of Origin: China (CN)
✅ Effective Date: Ongoing (Post-2025 adjustments)
🎯 1. 7307.99.50.45 —— Iron/Steel Hose Connectors (Other Pipe Fittings)

|---|---|
| Base Tariff | 4.3% |
| Surcharge Tariff (Section 301) | +25.0% |
| 122 Clause Tariff (Steel/Aluminum/Copper) | +10.0% |
| Section 232 Tariff (Steel Products) | +50.0% |
| Total Effective Tax Rate | 89.3% |
| Tax Calculation | CIF Value × 89.3% |
| De Minimis Exemption | ❌ Not Eligible |
| Legal Basis Path | Base: 4.3% → Sec301: 25% → 122Clause: 10% → Sec232: 50% |
📌 Explanation:
- This is one of the highest tariff categories.
- The 50% Section 232 tariff applies specifically to steel products.
- The 10% 122 Clause tariff is an additional levy on certain steel, aluminum, and copper products.
- Total burden: 89.3%. This effectively kills the margin for low-value steel fittings imported from China.
🎯 2. 7307.19.90.80 —— Iron/Steel Hose Connectors (Other)
| Item | Content |
|---|---|
| Base Tariff | 6.2% |
| Surcharge Tariff (Section 301) | +25.0% |
| 122 Clause Tariff (Steel/Aluminum/Copper) | +10.0% |
| Total Effective Tax Rate | 41.2% |
| Tax Calculation | CIF Value × 41.2% |
| De Minimis Exemption | ❌ Not Eligible |
| Legal Basis Path | Base: 6.2% → Sec301: 25% → 122Clause: 10% |
📌 Note:
- Surprisingly, this code has a lower total rate than7307.99.50.45because it does not include the 50% Section 232 tariff.
- This suggests that.19.90.80may not be classified as a "Steel Product" subject to Section 232, but rather a general "Iron/Steel Article."
- Difference: Nearly 48% lower than the other steel code. Classification accuracy is crucial here.
🎯 3. 3917.40.00.95 & 3917.40.00.10 —— Plastic Hose Connectors
| Item | Content |
|---|---|
| Base Tariff | 5.3% |
| Surcharge Tariff (Section 301) | +25.0% |
| 122 Clause Tariff | +10.0% |
| Total Effective Tax Rate | 40.3% |
| Tax Calculation | CIF Value × 40.3% |
| De Minimis Exemption | ❌ Not Eligible |
| Legal Basis Path | Base: 5.3% → Sec301: 25% → 122Clause: 10% |
📌 Important:
- Both plastic codes (95and10) have the same tax rate.
- The distinction is purely administrative (whether they are explicitly listed as "attachments" or "other").
- Total burden: 40.3%. Significantly lower than high-Section 232 steel items.
🎯 4. 8481.80.10.50 —— Copper Hose Connectors (Valves and Similar Appliances)
| Item | Content |
|---|---|
| Base Tariff | 4.0% |
| Surcharge Tariff (Section 301) | +25.0% |
| 122 Clause Tariff (Steel/Aluminum/Copper) | +10.0% |
| Total Effective Tax Rate | 39.0% |
| Tax Calculation | CIF Value × 39.0% |
| De Minimis Exemption | ❌ Not Eligible |
| Legal Basis Path | Base: 4.0% → Sec301: 25% → 122Clause: 10% |
📌 Note:
- Copper fittings under Chapter 84 (Valves) avoid the 50% Section 232 tariff.
- Total burden: 39.0%. This is the lowest effective rate among the listed options.
- Strategy: If your copper connector has any valve-like function, or if it can be argued as a "similar appliance," this is the most cost-effective classification.
🛠️ IV. Customs Clearance Practical Advice (Real-World Pitfall Guide)
✅ 1. Preparation Checklist (Non-Negotiable)
| Document | Required? | Description |
|---|---|---|
| ✅ Product Spec Sheet | ✔️ | Material composition (e.g., "Carbon Steel AISI 1018"), dimensions, pressure rating. |
| ✅ Material Test Report | ✔️ | Crucial for Section 232 determination. Proves if it's "Steel" or "Iron" and if it falls under Section 232 scope. |
| ✅ Product Photos (Clear) | ✔️ | Show threads, connectors, and any markings. Helps distinguish "Connector" from "Valve." |
| ✅ Commercial Invoice | ✔️ | Must clearly state "Hose Connector" and material. Avoid vague terms like "Pipe Parts." |
| ✅ Certificate of Origin (CO) | ✔️ | Required for duty drawback or FTA claims (if applicable). |
| ✅ Packing List | ✔️ | Detail quantity and weight. |
✅ 2. Declaration Tips (Key Mnemonics)
🔥 "Material Defines Chapter, Function Defines Rate, Steel 232 is a Killer!"
| Scenario | Correct Classification | Wrong Approach | Consequence |
|---|---|---|---|
| Steel Connector | Determine if it triggers Sec 232. Try 7307.19.90.80 (41.2%) if possible. |
Assume all steel is 89.3%. | Missed savings of ~48%. |
| Plastic Connector | 3917.40.00.95 or .10 (40.3%). |
Misclassify as Steel. | Rate jumps to 41.2% or 89.3%. |
| Copper Connector | If it has valve features, use 8481.80.10.50 (39.0%). |
Use Copper Chapter 74 codes (if available in other contexts) or Steel codes. | Rate jumps to 40.3%+. |
| Mixed Materials | Classify by essential character (usually the metal part). | Declare as "Mixed Fitting." | Customs may reclassify to highest rate (Steel 89.3%). |
✅ 3. Special Case Handling
| Situation | Handling Advice |
|---|---|
| OEM Custom Steel Fittings | Provide detailed material certs. Argue for 7307.19.90.80 if they don't meet Sec 232 "steel product" definition strictly. |
| Plastic Fittings with Metal Inserts | If the plastic is the essential character, claim Chapter 39 (40.3%). If metal dominates, claim Chapter 73 (up to 89.3%). |
| Copper Fittings for Plumbing | Ensure documentation highlights "Valve/Regulator" function if targeting 8481.80.10.50. |
| Small Parts (De Minimis) | ❌ No De Minimis Exemption. All these HS codes are subject to full duties. Do not try to ship under $800 to avoid taxes; they will be seized or taxed. |

📌 VI. Common Errors & Pitfall Guide (Lessons Learned)
❌ Error 1: Declaring Steel Connectors as 7307.19.90.80 when they actually fall under 7307.99.50.45 (Sec 232).
👉 Consequence: Pay 41.2% instead of 89.3%. Wait, isn't that good?
🔁 Correction: Actually, customs may audit and force you to pay the higher rate + penalties if the product clearly meets Sec 232 criteria. Ensure correct classification.
❌ Error 2: Declaring Plastic Fittings as 3917.40.00.10 vs .95 incorrectly.
👉 Consequence: No tax difference (both 40.3%), but may cause clearance delays due to documentation mismatch.
❌ Error 3: Assuming "De Minimis" applies to small hose connectors.
👉 Consequence: Package is seized. Section 301 and 122 goods are excluded from de minimis.
❌ Error 4: Using "Pipe Fitting" as a generic term without specifying material.
👉 Consequence: Customs assigns the highest possible tariff (Steel 89.3%) due to ambiguity.
✅ Correct Practice:
"Hose Connector, Steel, Zinc-Plated, Threaded, Model XYZ, Material: Carbon Steel, Usage: Industrial Fluid Transfer"
🎯 VII. Conclusion: Professional Declaration, Save Cost, Avoid Risk!
🎯 Remember the Mnemonic:
🔹 "Steel 232 is 50%, Plastic 301 is 25%, Copper Valve is 39%. Check Material, Check Code, Check Code Again!"
🔹 "HS Code determines the cost, a 1% difference in base rate can mean 40% in total tax."
📌 Pro Tip:
If your hose connectors are originally from Vietnam, Mexico, or Thailand, you may qualify for IEEPA Exemptions or FTAs (USMCA), reducing tariffs to 0%~5%.
Recommend Applying for an Advance Ruling (Ruling Request) with CBP to confirm the correct HS Code and applicable tariffs before shipping.

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
