🔥 Wood Pellet Fuel Standard Block (Solid Biomass Fuel)
🌐 HS Code Reference & Customs Clearance Guide | 2026 Latest Tariff Analysis | Professional Clearance Strategy
📌 I. Product Definition and Classification: Do You Really Understand "Wood Pellets"?
Wood Pellets are a type of solid biofuel produced by compressing sawdust, wood waste, or other lignocellulosic biomass into small, cylindrical shapes (pellets), logs, briquettes, or similar forms. They are widely used for heating in residential boilers, industrial power plants, and commercial heating systems due to their high energy density and low moisture content.
In international trade, this category is strictly divided based on the form of agglomeration:
Wood Pellets (Agglomerated in Pellet Form): Small, uniform cylindrical rods, typically 6-8mm in diameter and 10-30mm in length, specifically classified as "Wood Pellets." Other Agglomerated Wood Waste (Logs, Briquettes, Faggots, etc.): Larger blocks, logs, or irregularly shaped compressed wood waste that does not fit the standard "pellet" definition.
⚠️ Key Distinction Point: - If the product is in small, uniform cylindrical shapes (6-8mm) → Classified as "Wood Pellets" (4401.31.00.00) - If the product is in large logs, large briquettes, or other non-pellet agglomerated forms → Classified as "Other Sawdust/Waste" (4401.39.42.10) - ⚠️ Do not confuse with raw sawdust (powder) or unprocessed wood chips. These products are agglomerated.
📦 II. HS Code Classification Details (2026 Latest Tariff Authority Comparison)
Based on the provided data, there are two specific HS codes under the category of "Sawdust and wood waste and scrap, agglomerated in logs, briquettes, pellets or similar forms".
| HS Code | Product Description | Applicable Scenario | Agglomeration Form |
|---|---|---|---|
4401.31.00.00 |
Wood Pellets | Standard residential/commercial heating pellets (6-8mm cylindrical) | ✅ Pellets |
4401.39.42.10 |
Other: Other Sawdust | Agglomerated wood waste in forms other than pellets (e.g., large briquettes, logs, faggots) | ✅ Logs/Briquettes/Other |
🔍 Key Reminder: - "Wood Pellets" specifically refer to the small, standardized cylindrical fuel rods. - "Other" covers any agglomerated form that is not a standard pellet, including large briquettes, log-shaped agglomerates, or faggots. - Both categories fall under Chapter 44 (Wood and Articles of Wood), specifically Heading 4401 (Fuel wood...).
💰 III. 2026 Latest Tariff Rate Breakdown (Including Additional Duties)

| Item | Content |
|---|---|
| Base Tariff Rate | 0% (Ad Valorem) |
| Additional Tariff (Section 301) | +25% |
| Total Tax Rate | 25.0% |
| Tax Calculation | CIF Value × 25% |
| De Minimis Exemption | ❌ Not Applicable |
| Legal Basis Path | HTSUS:4401.39.42.10 → Section 301 Footnote 9903.88.01 (if applicable) |
📌 Note: - Similar to wood pellets, the base tariff is 0%. - The +25% additional tariff also applies to other agglomerated wood waste forms. - Total Effective Rate: 25%. - Crucial: Even though the HS codes differ, the total tax burden is identical (25%). Therefore, accurate classification is critical for customs inspection and compliance, not just tax calculation.
🛠️ IV. Customs Clearance Practical Advice (Real-World Pitfall Avoidance Guide)
✅ 1. Documentation Checklist (Missing Items Cause Delays)
| Document | Must Provide | Description |
|---|---|---|
| ✅ Product Specification Sheet | ✔️ | Must specify form (pellet vs. briquette), dimensions, density, moisture content (<10% recommended). |
| ✅ Material Composition Certificate | ✔️ | Proof that it is 100% wood biomass (no plastic binders, chemicals, or contaminants). |
| ✅ Commercial Invoice | ✔️ | Clearly state "Wood Pellets" or "Agglomerated Wood Waste" with HS Code. |
| ✅ Packing List | ✔️ | Detail packaging type (bagged, bulk, palletized). |
| ✅ Certificate of Origin (CO) | ✔️ | Required to prove origin (China) for Section 301 applicability. |
| ✅ Phytosanitary Certificate | ✔️ | Often required for biomass products to prove pest-free status. |
| ✅ Third-Party Test Report | ✔️ | ASTM D5512/D6866 or similar standards for energy density and ash content. |
✅ 2. Declaration Tips (Key Mantra)
🔥 "Form Defines Code, Origin Dictates Tax, Documentation Ensures Speed!"
| Scenario | Correct Declaration | Incorrect Practice |
|---|---|---|
| Standard 6-8mm cylindrical fuel | 4401.31.00.00 (Wood Pellets) |
Declare as "Briquettes" → Higher inspection risk |
| Large 50mm compressed blocks | 4401.39.42.10 (Other) |
Declare as "Wood Pellets" → Misclassification |
| Raw sawdust (unagglomerated) | Different HS Code (e.g., 4401.40) | Declare as "Pellets" → Severe Penalty |
| Wood chips (uncompressed) | Different HS Code (4401.21) | Declare as "Pellets" → Wrong Category |
✅ 3. Special Situation Handling
| Situation | Handling Advice |
|---|---|
| Mixed Packaging (Pellets + Briquettes) | Split Declaration: Declare pellets under 4401.31.00.00 and briquettes under 4401.39.42.10. Do not lump them together. |
| High Moisture Content (>10%) | May be classified as "Green Wood" or subject to additional phytosanitary checks. Ensure moisture is clearly stated. |
| Additives (Binders, Glues) | If additives exceed 5%, it may no longer be considered "Wood Waste" but a "Manufactured Product," potentially changing the HS code entirely. |
| OEM Custom Pellets | Provide customer order + specification sheet to prove intended use (heating fuel). |

📌 VI. Common Mistakes & Pitfalls (Blood Lessons)
❌ Mistake 1: Declaring all agglomerated wood waste as 4401.31.00.00 (Wood Pellets)
👉 Consequence: If goods are large briquettes, customs will reclassify them to 4401.39.42.10, causing delays and inspections.
❌ Mistake 2: Ignoring Phytosanitary Requirements
👉 Consequence: Biomass products are prone to pests. Lack of a Phytosanitary Certificate can lead to quarantine or destruction of goods.
❌ Mistake 3: Failing to specify Moisture Content
👉 Consequence: High moisture (>10-12%) may lead to classification as "Green Wood" or rejection due to mold risk.
❌ Mistake 4: Not declaring Additives
👉 Consequence: If binders/chemicals are used, it may not be "Wood Waste" anymore, leading to wrong HS code and penalties.
✅ Correct Practice:
"Wood Pellets, 6mm Diameter, 20mm Length, Moisture <8%, 100% Pine Wood, No Additives, ASTM D6866 Certified, Bagged on Pallets"
🎯 VII. Conclusion: Professional Declaration, Save Time, Reduce Costs!
🎯 Remember the Mantra:
🔹 "Pellets = 4401.31, Briquettes = 4401.39, Tax is 25%, Documentation is Key!"
🔹 "Check Moisture, Check Additives, Check Phytosanitary, Avoid Delays!"
📌 Pro Tip:
- For US Imports, budget for the 25% additional tariff in your cost structure.
- Consider Third-Party Pre-Clearance or HS Code Advance Ruling to avoid surprises at the port.
- Ensure ENplus® or ASTM certification is up-to-date, as customs increasingly request these for biomass products.

About HS Code Classification
The Harmonized System (HS) is an internationally standardized nomenclature developed by the World Customs Organization (WCO) to classify traded products. Over 200 countries use the HS system as the basis for customs tariffs, trade statistics, and import/export regulations.
Each HS code follows a hierarchical structure:
- Chapter (2 digits) — Broad category of goods (e.g., Chapter 84: Machinery and Mechanical Appliances)
- Heading (4 digits) — More specific grouping within the chapter
- Subheading (6 digits) — Internationally standardized breakdown, used by all WCO member countries
- National subdivisions (8-10 digits) — Country-specific extensions for further classification, such as US HTSUS 10-digit codes
Correct HS code classification is essential for smooth customs clearance, accurate duty payment, and compliance with trade regulations. Misclassification can lead to customs delays, overpayment of duties, or penalties.
When importing from CN to US, the applicable tariff rates may include:
- Most-Favored-Nation (MFN) rate — The standard duty rate applied to WTO members
- General rate — Applied to countries without trade agreements
- Trade remedy duties — Additional tariffs such as Section 301 (anti-dumping), Section 232 (national security), or countervailing duties
