⚙️ Carburetor Kit (Parts for Spark-Ignition Internal Combustion Engines)
🌐 HS Code Reference & Clearance Guide | 2026 Latest Tariff Analysis | Professional Customs Strategy
📌 I. Product Definition & Classification: What Exactly is a "Carburetor Kit"?
A Carburetor Kit typically refers to a set of parts used for the maintenance, repair, or rebuild of carburetors in internal combustion engines. Unlike complete carburetors (which are classified under Chapter 84), a kit consists of discrete components such as jets, diaphragms, gaskets, screws, and needles.
In international trade and customs classification, the critical distinction lies in whether the item is a complete assembly or individual parts. Under the Harmonized System (HS), "parts suitable for use solely or principally with engines" fall under Heading 8409.
⚠️ Key Distinction:
- If the product is a complete, assembled carburetor → It is classified under 8408/8407 (Engines) or specifically as an engine part/assembly depending on jurisdiction interpretation, but often misclassified. Note: The provided data focuses on Parts (Heading 8409).
- If the product is a Kit of Parts (disassembled components) → It is strictly classified as a Part under Heading 8409.
- Specific Engine Type Matters: The tax rate differs significantly between Spark-Ignition Engines (e.g., gas engines, motorcycles, small cars) and Compression-Ignition Engines (diesel). Most "Carburetor Kits" are for Spark-Ignition (Gasoline) engines.
📦 II. HS Code Classification Details (Based on Provided Data)
The provided data contains four distinct HS Codes. For a Carburetor Kit, the most relevant classification is 8409.91 (Parts for Spark-Ignition Engines). The other codes relate to Filters (8421) or Cast-Iron Parts (8409.91.10), which are not typical "kits" but specific raw or semi-finished components.
| HS Code | Product Description | Applicability to Carburetor Kit | Tax Impact |
|---|---|---|---|
8409.91.50.81 |
Parts suitable for use solely or principally with engines of heading 8407 or 8408: Suitable for spark-ignition engines: Steel forgings | ✅ MOST RELEVANT if the kit contains forged steel components (e.g., main body, precision machined jets). This is the standard classification for finished steel parts kits for gasoline engines. | Total Tax: 27.5% |
8409.91.10.40 |
Parts suitable for use solely or principally with engines of heading 8407 or 8408: Cast-iron parts, not advanced beyond cleaning, and machined only for removal of fins/gates... | ⚠️ PARTIAL MATCH Only if the "kit" consists solely of unprocessed cast iron blocks (rare for a consumer "kit"). Unlikely for standard carburetor kits which include precision jets/diaphragms. | Total Tax: 25.0% |
8421.23.00.00 |
Filtering or purifying machinery for liquids: Oil or fuel filters for internal combustion engines | ❌ IRRELEVANT unless the kit contains only filters. A carburetor kit is not a fuel filter. | Total Tax: 0.0% |
8421.31.00.00 |
Filtering or purifying machinery for gases: Intake air filters for internal combustion engines | ❌ IRRELEVANT unless the kit contains only air filters. A carburetor kit is not an air filter. | Total Tax: 0.0% |
🔍 Critical Note:
- The vast majority of Carburetor Kits for small engines (lawnmowers, motorcycles, ATVs) are classified under8409.91.50.81because they contain precision steel parts intended for spark-ignition engines.
- The filters (8421) are NOT carburetor kits. Do not misclassify a carburetor kit as a filter to avoid penalties.
💰 III. 2026 Latest Tariff Rate Breakdown (Detailed Analysis)
✅ Applicable Country: United States (US)
✅ Origin: China (CN)
✅ Effective Time: Current trade policies apply (2025-2026)
🎯 1. 8409.91.50.81 – Carburetor/Engine Parts (Steel Forgings for Spark-Ignition Engines)
| Item | Content |
|---|---|
| Base Tariff | 2.5% (Most Favored Nation / Standard) |
| Section 301 Additional Tariff | +25.0% (Retaliatory tariff on Chinese goods) |
| Total Tariff Rate | 27.5% |
| Tax Calculation | CIF Value × 27.5% |
| De Minimis Exemption | ❌ NOT APPLICABLE (Section 321 de minimis does not apply to goods subject to Section 301 tariffs above $800 if specifically listed, or more importantly, commercial shipments are always taxed). |
| Legal Path | HTSUS: 8409.91.50.81 → USITC Footnote 9903.88.01 (Section 301) |
📌 Explanation:
- Why 27.5%? The base rate for engine parts is low (2.5%), but the 25% Section 301 tariff is the dominant cost driver for Chinese-origin goods.
- No Exemption: Unlike some consumer electronics, engine parts for vehicles are generally not exempt from Section 301 tariffs unless specifically carved out (check USTR exclusions list, but generally, they are included).
- Comparison: If you mistakenly classify this as a Filter (8421.23.00.00), the tax is 0%, but this is illegal misclassification and carries severe penalties.
🎯 2. 8409.91.10.40 – Cast-Iron Engine Parts
| Item | Content |
|---|---|
| Base Tariff | 0.0% |
| Section 301 Additional Tariff | +25.0% |
| Total Tariff Rate | 25.0% |
| Applicability | Only for crude cast iron blocks, not complete kits with precision parts. |
🛠️ IV. Customs Clearance Practical Advice (Avoid Pitfalls)
✅ 1. Documentation Checklist (Mandatory)
| Document | Required? | Description |
|---|---|---|
| ✅ Commercial Invoice | ✔️ | Must explicitly state: "Carburetor Rebuild Kit – Steel Parts" not just "Auto Parts". |
| ✅ Packing List | ✔️ | Detail the contents: e.g., "10x Jets, 2x Diaphragms, 5x Gaskets". |
| ✅ Product Photos | ✔️ | Show the kit contents clearly to prove it is a "Kit of Parts" and not a complete engine or filter. |
| ✅ HS Code Pre-ruling | ✔️ | Highly recommended to confirm 8409.91.50.81 vs 8409.91.10.40. |
| ✅ Country of Origin | ✔️ | Must declare China (CN) if manufactured there to apply the correct 25% additional duty. |
✅ 2. Declaration Tips (Key Mnemonic)
🔥 "Kit is Part, Not Filter, Steel for Gas, 27.5% Clear!"
| Scenario | Correct Declaration | Wrong Declaration | Consequence |
|---|---|---|---|
| Carburetor Kit (Steel Parts) | 8409.91.50.81 |
8421.23.00.00 (Filter) |
Penalty: Misclassification, potential seizure, back taxes + fines. |
| Carburetor Kit (Cast Iron Block) | 8409.91.10.40 |
8409.91.50.81 |
Risk: Overpayment or Underpayment depending on actual value/weight. |
| Complete Carburetor (Assembled) | 8409.91.50.81 (as part) or 8408 (as engine part) |
8421.31.00.00 (Air Filter) |
High Risk:海关 will reject as it is not an air filter. |
| Air Filter Only | 8421.31.00.00 |
8409.91.50.81 |
Underpayment: Tax should be 0%, but declared as 27.5% (harmless but inefficient). |
✅ 3. Special Case Handling
| Situation | Recommendation |
|---|---|
| Kit contains both Steel & Plastic Parts | Classify as Steel Parts (8409.91.50.81) because steel is the principal material/value driver in precision carburetor jets. |
| Kit includes Gaskets/Diaphragms | Do not split the shipment. A "kit" is considered a single unit for classification. |
| Importing for OEM Repair | Provide OEM Contract and Repair Order. Prove it is a "part for use" to avoid being classified as "Used Goods" (which may have different restrictions). |
| Origin: Vietnam/Malaysia | If the kit is assembled in these countries with sufficient transformation, you may avoid the 25% Section 301 tariff, resulting in only 2.5% base duty. Critical for cost savings! |
🌍 V. Global Market Comparison (2026)
| Country/Region | Recommended HS Code | Tariff (China Origin) | Certification | Notes |
|---|---|---|---|---|
| 🇺🇸 USA | 8409.91.50.81 |
27.5% (2.5% + 25%) | No special cert | High tariff due to Section 301. |

0% (Under USMCA if qualified) | N/A | If produced in NA region, duty-free. |
📌 Conclusion:
- The USA is the most expensive market for Carburetor Kits from China due to the 25% Section 301 tariff.
- EU and UK tariffs are significantly lower (~4.5%).
- Supply Chain Strategy: Consider assembling kits in Vietnam, Malaysia, or Mexico to qualify for preferential rates or avoid Section 301 duties.
📌 VI. Common Errors & Pitfalls (Blood & Tears)
❌ Error 1: Classifying Carburetor Kit as Fuel Filter (8421.23.00.00)
👉 Consequence: 0% Tax initially, but Customs will audit, find misclassification, and assess 27.5% back taxes + 20% penalty.
👉 Reason: A carburetor kit is not a filter; it controls fuel mixture, not filters fuel.
❌ Error 2: Classifying as Air Filter (8421.31.00.00)
👉 Consequence: Same as above. Customs experts easily distinguish between air filters and carburetor parts.
❌ Error 3: Declaring "Auto Parts" Generic
👉 Consequence: Customs may assign the highest possible duty rate for ambiguity, which could be higher than 27.5% if interpreted as a complete engine part assembly under a different subheading.
✅ Correct Practice:
"Carburetor Rebuild Kit, Model XYZ, for Spark-Ignition Engine, Steel Jets & Diaphragms, HS Code 8409.91.50.81"
🎯 VII. Conclusion: Professional Declaration, Cost Efficiency!
🎯 Remember the Mnemonic:
🔹 "Kit is Part, Not Filter, Steel for Gas, 27.5% Clear!"
🔹 "Misclassify as Filter, 27.5% Back Tax + Penalty!"
📌 Pro Tip:
If your Carburetor Kits are manufactured in Vietnam, Malaysia, or Thailand, ensure you have a Certificate of Origin to prove they are not Chinese-made. This can reduce your tariff from 27.5% to 2.5% (Base Rate).
For US imports, pre-ruling is highly recommended to confirm 8409.91.50.81 is appropriate for your specific kit composition.

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
