🌐 HS Code Reference & Customs Clearance Guide | 2026 Latest Tariff Analysis | Professional Strategy
📌 I. Product Definition & Classification: Understanding "Paraffin-Based Grease"

Paraffin-based grease is a semi-solid lubricant derived from petroleum products. It is characterized by its high melting point, excellent water resistance, and stability under high-temperature conditions compared to mineral oil-based greases. In international trade, its classification depends heavily on its physical state, base material, and intended application.

Based on the provided data, this product falls under three potential HS Codes, all sharing similar tax structures due to trade restrictions on Chinese-origin goods.

⚠️ Key Distinction Point:
- State of Matter: Is it a solid/semi-solid grease or a liquid oil?
- If Grease (semi-solid): Generally falls under 3403.19 or 2710.19.
- If Oil (liquid): Falls under 2710.19 (different subheading).
- Material Source: Paraffin-based indicates it is a petroleum derivative.

📦 II. HS Code Classification Details (Based on Provided Data)

🔍 Critical Analysis:
- HS 2710 covers "Petroleum oils and other products of their extraction." Grease can fall here if treated primarily as a petroleum product.
- HS 3403 covers "Prepared lubricating preparations." This is often the more accurate classification for finished greases intended for mechanical lubrication.
- Tax Consistency: Despite different HS codes, the total tax burden for 2710.19.35.00 and 3403.19.50.00 is identical (40.8%). However, 2710.19.40.00 has a different structure (1.3¢/kg + 40.7% total ad valorem equivalent).

💰 III. 2026 Latest Tariff Rate Breakdown (Including Surcharges & Policy Add-ons)

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

🎯 1. 2710.19.35.00 & 3403.19.50.00 —— Paraffin-Based Grease (Standard Classification)

📌 Explanation:
- The 5.8% is the standard Most Favored Nation (MFN) or base rate for these petroleum/lubricant categories.
- The 25.0% is the widely known Section 301 tariff on Chinese goods, which applies to most lubricants and petroleum derivatives.
- The 10.0% is a specific "Section 122" tariff, often applied to certain steel/aluminum or specific chemical/petroleum products subject to national security or emergency powers.
- Total 40.8% is a significant cost driver. Importers must factor this into their landed cost calculations.

🎯 2. 2710.19.40.00 —— Paraffin-Based Grease (Alternative Classification)

📌 Note:
- This HS code introduces a specific duty (per kg) in addition to the ad valorem rate. For heavy shipments, the per-kg cost may add up, but the ad valorem percentage is slightly lower (40.7% vs 40.8%).
- The difference is negligible in most cases, but HS Code selection must be accurate to avoid customs penalties. Misclassification can lead to underpayment and subsequent audits.

🛠️ IV. Customs Clearance Practical Advice (Real-World Pitfall Avoidance)

✅ 1. Documentation Checklist (Mandatory)

✅ 2. Declaration Strategy (Key Tips)

🔥 “Accurate HS, Clear Description, Weight Matters!”

📌 Important:
- Ensure the product is described as "Grease" (semi-solid) and not "Oil" (liquid). Liquid petroleum products have different HS codes and potentially different tax treatments.
- Paraffin-based grease is often used in high-temperature applications (e.g., steel mills, food processing). Highlighting this in specs can help customs understand the product nature.

✅ 3. Special Considerations

🌍 V. Global Market Comparison (2026 Latest)

📌 Conclusion:
- The US market is the most challenging due to the 40.8% effective tariff.
- Competitors from Vietnam, Thailand, or EU have a competitive advantage due to lower or zero tariffs.
- Importers should evaluate if local sourcing or third-country assembly is viable.

📌 VI. Common Mistakes & Pitfalls (Lessons Learned)

❌ Mistake 1: Declaring "Grease" under "Petroleum Oil" (e.g., 2710.19.20)
👉 Consequence: Customs may reject the declaration for misclassification → Delay + Penalty.
👉 Correction: Use 3403.19.50.00 for prepared lubricants.

❌ Mistake 2: Ignoring the Specific Duty in HS 2710.19.40.00
👉 Consequence: Underpayment of duty if weight is not accurately declared.
👉 Correction: Always verify weight in kg for hybrid duties.

❌ Mistake 3: Assuming "Paraffin-Based" qualifies for any exemption
👉 Consequence: No exemption available for standard paraffin grease under current trade policies.
👉 Correction: Budget for the full 40.8% tariff.

✅ Correct Practice:

"Paraffin-Based Lubricating Grease, NLGI Grade 2, for Industrial Bearings, Model XYZ, Country of Origin: China"

🎯 VII. Conclusion: Professional Declaration, Cost Control, Risk Mitigation

🎯 Remember the Key Points:

🔹 "HS Code Accuracy is Critical": 3403.19.50.00 or 2710.19.35.00 are the most common.
🔹 "Total Duty is 40.8%": Include base (5.8%) + Section 301 (25%) + Section 122 (10%).
🔹 "Documentation is Key": SDS and Specifications are mandatory for smooth clearance.

📌 Pro Tip:

If your volume is significant, consider applying for an Advance Ruling from US Customs to confirm the HS Code and duty calculation before shipment. This reduces the risk of post-entry audits and back-taxes.

📣 Immediate Action:

📞 Consult with a licensed US Customs Broker.
📄 Prepare complete product specifications and SDS.
💰 Calculate landed cost including the 40.8% tariff.
