πͺ΅ Preserved Coniferous Wood Boards (Sawn/Sliced)
π HS Code Reference & Customs Clearance Guide | 2026 Latest Tariff Analysis | Professional Clearance Strategy
π I. Product Definition and Classification: Do You Really Understand "Preserved Coniferous Wood"?
Preserved coniferous wood boards are processed timber products, primarily used in construction, furniture making, pallet manufacturing, and outdoor engineering. In international trade, they are strictly categorized based on wood species (Coniferous) and surface treatment (Preserved).
Key Distinction: - Unpreserved Wood: Raw sawn wood without chemical treatment. - Preserved Wood: Wood treated with paint, stain, creosote, or other preservatives to prevent rot, insect attack, or decay.
β οΈ Critical Classification Point:
- If the wood is treated with preservatives (e.g., creosote, paint, stain), it MUST be classified under subheadings ending in .02.
- If untreated, it falls under subheadings ending in .01.
- Thickness: Must exceed 6 mm to be classified as "sawn/sliced wood." Thinner sheets may fall under plywood or veneer categories (not covered here).
π¦ II. HS Code Classification Details (2026 Latest Tariff Authority)
| HS Code | Product Description | Applicable Scenario | Treatment Status |
|---|---|---|---|
4407.11.00.02 |
Pine (Pinus spp.) sawn wood, treated with paint, stain, creosote, or other preservative | Outdoor decking, construction timber, pallets made of pine, treated with anti-rot chemicals | β Treated |
4407.12.00.02 |
Fir/ Spruce (Abies spp. and Picea spp.) sawn wood, treated with paint, stain, creosote, or other preservative | Structural lumber, framing timber, industrial use fir/spruce, chemically preserved | β Treated |
π Key Reminder:
- Both codes fall under Chapter 44, specifically 4407: "Wood sawn or chipped lengthwise, sliced or peeled... of a thickness exceeding 6 mm."
- Subheading .11 is for Pine.
- Subheading .12 is for Fir and Spruce.
- The suffix .02 explicitly denotes "Treated with preservative."
- Misclassification (e.g., declaring untreated wood as treated, or wrong species) can lead to customs delays, penalties, or reclassification.
π° III. 2026 Latest Tariff Rate Breakdown (Including Additional Duties)
β Applicable Country: United States (US)
β Origin: China (CN)
β Effective Date: Ongoing (Subject to Section 301 Duties)
π― 1. 4407.11.00.02 β Treated Pine Sawn Wood
| Item | Content |
|---|---|
| Base Tariff Rate | 0.0% (ad valorem) |

|---|---|
| Base Tariff Rate | 0.0% |
| Section 301 Additional Duty | +25.0% |

π Note:
- Same tariff structure as Pine.
- Applies to all fir and spruce species (Abies and Picea) that are preserved.

π οΈ IV. Customs Clearance Practical Advice (Field Avoidance Guide)
β 1. Required Documentation Checklist (Non-negotiable)
| Document | Must Provide | Description |
|---|---|---|
| β Product Specification Sheet | βοΈ | Must specify: Wood species (Pine/Fir/Spruce), treatment type (Creosote/Paint/etc.), thickness, dimensions |
| β Preservation Treatment Certificate | βοΈ | Proof of treatment process (e.g., ACQ, CCA, Creosote) from the manufacturer or third-party lab |
| β Commercial Invoice | βοΈ | Must clearly state: "Sawn Wood of [Species], Treated with [Preservative], Thickness >6mm" |
| β Packing List | βοΈ | Detail weights, volumes, and number of bundles/containers |
| β Fumigation Certificate | βοΈ | Required by ISPM 15 if wood is not processed (but note: preserved wood may be exempt from fumigation if heat-treated/preserved, check with CBP) |
| β Bill of Lading/Air Waybill | βοΈ | Standard shipping documents |
β 2. Declaration Tips (Key Mantra)
π₯ "Species Clear, Treatment Stated, Thickness Verified, Duty Avoids Mistakes!"
| Scenario | Correct Declaration | Wrong Practice |
|---|---|---|
| Treated Pine Lumber | 4407.11.00.02 |
Declare as "Untreated Wood" β Risk of penalty |
| Treated Spruce Framing | 4407.12.00.02 |
Declare as "Plywood" β Wrong code, potential seizure |
| Mixed Species Shipment | Split declaration per species | Lump-sum declaration β Customs may reclassify and penalize |
| Wood <6mm thick | Not eligible for these codes | Try to force fit β Rejection |
π Important:
- Ensure the HS code suffix ".02" is clearly indicated if the system allows manual entry. If not, ensure the description explicitly mentions "Treated with preservative."
- Do not declare as "Wood Products" vaguely. Specificity is key.
β 3. Special Cases Handling
| Case | Handling Advice |
|---|---|
| Heat-Treated + Painted | Still classified as "Treated" under .02 if paint/preservative is present. Fumigation may be waived, but duty remains 25%. |
| Certified Wood (FSC/PEFC) | Provides environmental proof but does NOT reduce tariff rate. Still subject to 25%. |
| Mixed Shipments (Pine + Fir) | Must declare separately if possible, or use the highest applicable rate if mixed (usually same rate here). Better to separate. |
| Used Wood | If "used" but preserved, still generally falls under 4407 if sawn. Ensure it meets ISPM 15 standards if not treated. |
π V. Global Market Comparison (2026 Latest)
| Country/Region | Recommended HS Code | Tariff (China Origin) | Certification Requirements | Notes |
|---|---|---|---|---|
| πΊπΈ USA | 4407.11.00.02 / 4407.12.00.02 |
25% | Fumigation/ISPM 15 | High duty due to Section 301 |
| π¨π³ China | 4407.11.00.02 / 4407.12.00.02 |
Varies (Export) | N/A | Export incentives may apply |
| πͺπΊ EU | 4407 11 / 4407 12 |
~0-20% (depends on specific) | REACH, FSC (if claimed) | EU has different duty schedules |
| π¬π§ UK | 4407 11 / 4407 12 |
Similar to EU | UKCA marking if applicable | Post-Brexit rules apply |
| π¦πΊ Australia | 4407 11 / 4407 12 |
~0-5% | Biosecurity strictness | High biosecurity checks |
π Conclusion:
- USA imposes a flat 25% additional tariff on these wood products from China.
- EU/UK may have lower base duties but stricter environmental and biosecurity regulations.
- Biosecurity is the biggest non-tariff barrier globally for wood products.
π VI. Common Mistakes & Pitfalls (Lessons Learned)
β Mistake 1: Declaring "Untreated" when wood is actually treated with preservative
π Consequence: Misclassification, potential fraud charges, and back-tariff penalties.
β Mistake 2: Ignoring species distinction (Pine vs. Fir/Spruce)
π Consequence: While both have 25% duty in the US, incorrect species can lead to delays and additional scrutiny.
β Mistake 3: Failing to provide treatment certificates
π Consequence: CBP may detain shipment for verification, causing storage fees and delays.
β Mistake 4: Assuming all wood products are exempt from Section 301
π Consequence: Wood products are explicitly included in the 25% additional duty list.
β Correct Practice:
"Pine Sawn Wood, 25mm Thickness, Treated with Creosote, ISPM 15 Compliant, HS Code 4407.11.00.02"
π― VII. Conclusion: Precision in Classification, Savings in Clearance
π― Remember the Mantra:
πΉ "Pine is .11, Fir is .12, Treated is .02, Duty is 25%!"
πΉ "Species matters, Treatment matters, Document everything!"
π Pro Tip:
- If your wood is sourced from Vietnam, Malaysia, or Thailand, the Section 301 25% duty does NOT apply. Verify Country of Origin carefully.
- Consider applying for a Pre-Ruling (Binding Ruling) from CBP if you have mixed treatments or unusual specifications.

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) β Broad category of goods (e.g., Chapter 84: Machinery and Mechanical Appliances)
- Heading (4 digits) β More specific grouping within the chapter
- Subheading (6 digits) β Internationally standardized breakdown, used by all WCO member countries
- National subdivisions (8-10 digits) β 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 β The standard duty rate applied to WTO members
- General rate β Applied to countries without trade agreements
- Trade remedy duties β Additional tariffs such as Section 301 (anti-dumping), Section 232 (national security), or countervailing duties
