⛽️ Carburetors (Fuel Mixing Devices for Internal Combustion Engines)

🌐 HS Code Reference & Customs Clearance Guide | 2026 Latest Tariff Analysis | Professional Clearance Strategy
📌 I. Product Definition & Classification: Do You Truly Understand “Carburetors”?

A carburetor is a critical component in internal combustion engines, responsible for mixing air and fuel in the correct ratio before entering the combustion chamber. In international trade, its classification depends heavily on specific application (e.g., general engine vs. agricultural machinery) and material composition. Misclassification here leads to significant tariff disparities.

⚠️ Key Distinction Point:
- General Purpose/Industrial Engine Parts: Materials are typically metal/steel or composite. → Falls under 8409.91 series.
- Lawn/Garden Machinery Parts: Specifically for agricultural or horticultural equipment engines. → Falls under 8407.90 series.

📦 II. HS Code Classification Details (2026 Latest Tariff Authority Comparison)

🔍 Important Reminder:
- 8407.90.10.x codes enjoy lower base tariffs (0%) because they are classified under agricultural/horticultural machinery parts.
- 8409.91.x codes are subject to a 2.5% base tariff as general engine parts.
- All these codes are subject to significant US additional tariffs due to their origin (China).

💰 III. 2026 Latest Tariff Rate Breakdown (Including Surtaxes, Policy Add-ons)

✅ Applicable Country: United States (US)
✅ Origin: China (CN)
✅ Effective Date: From November 10, 2025 (including subsequent imports)

🎯 1. 8409.91.50.81 / 8409.91.50.85 / 8409.91.99.90 —— General Engine Parts (Metal/Composite)

📌 Explanation:
- These carburetors are classified as "Other Parts of Internal Combustion Engines".
- The 2.5% is the standard MFN (Most Favored Nation) rate.
- The +25% is the standard Section 301 tariff on Chinese engine parts.
- The +10% is a specific "Section 122 Clause" surcharge applicable to certain engine components.
- Total: 37.5%. This is a high-cost category that significantly impacts profit margins.

🎯 2. 8407.90.10.80 / 8407.90.10.60 —— Lawn Mower/Agricultural Engine Parts

📌 Note:
- These carburetors are classified under "Parts of Engines for Agricultural or Horticultural Machinery".
- The 0% base tariff provides a slight advantage over general engine parts.
- However, the Section 301 (25%) and Section 122 (10%) surcharges still apply, bringing the total to 35%.
- Savings: Compared to the 37.5% rate, this saves 2.5% on the CIF value. While small, it is significant for high-volume shipments.

🛠️ IV. Customs Clearance Practical Advice (Battle-Tested Pitfall Avoidance)

✅ 1. Required Documentation Checklist (Missing Items Lead to Delays)

✅ 2. Classification Strategy (Key Mnemonic)

🔥 “Agri Parts First, Metal Second, Name It Precise, Tax Less!”

📌 Critical Tip:
- If your carburetor is exclusively for agricultural or horticultural machinery, ALWAYS use the 8407.90.10 series to secure the 0% base rate.
- If the use is ambiguous (e.g., "for small engines"), customs may default to 8409.91, incurring the 2.5% base tax.
- Proof of Use: Provide end-user documentation or machine manuals showing the carburetor is designed for 8407 machinery.

✅ 3. Special Cases & Handling

🌍 V. Global Market Clearance Comparison (2026 Latest)

📌 Conclusion:
- US Market: The 2.5% difference between 8407.90 and 8409.91 is critical. Always aim for 8407.90.10 if applicable.
- Other Markets: No Section 301/122 surcharges apply outside the US.

📌 VI. Common Errors & Pitfalls (Lessons Learned)

❌ Error 1: Classifying a Lawn Mower Carburetor as 8409.91.99.90
👉 Consequence: You pay 37.5% instead of 35%. Unnecessary cost increase.

❌ Error 2: Using "Carburetor" without specifying "For Agricultural Machinery"
👉 Consequence: Customs may default to the general engine part code (8409.91), triggering the 2.5% base tax.

❌ Error 3: Ignoring the "Section 122 Clause" (10%)
👉 Consequence: Underestimating total landed cost. This 10% is mandatory for these HS codes from China.

✅ Correct Practice:

"Carburetor for Garden Tractor, Model XYZ, Metal Body, Compatible with [Brand] 4-Stroke Engine"

🎯 VII. Conclusion: Precision Classification, Cost Optimization!

🎯 Remember the Mantra:

🔹 "Agri First, 35% Total; General Engine, 37.5% Control."
🔹 "Sec 301 is 25%, Sec 122 is 10%, Base Rate Makes the Difference!"

📌 Pro Tip:
If your carburetors are not for agricultural machinery but for general engines, 8409.91 is your only option. However, if there is any doubt about the end-use, provide robust documentation to argue for 8407.90 to save that 2.5%.
