π HS Code Reference & Customs Clearance Guide | 2026 Latest Tariff Analysis | Professional-Level Entry Strategy
π I. Product Definition & Classification: What Are "Composite Boards"?
Anti-static and UV-resistant composite boards are advanced industrial materials used for protective shielding, ESD (Electro-Static Discharge) control, and environmental durability. They are not simple plastic sheets; they are engineered composites with specific functional layers.
In international trade, the classification hinges on the base material: * Plastic/Resin-Based: The core is synthetic polymer (HDPE, PP, PVC, etc.). These fall under Chapter 39. * Cellulose/Paper-Based: The core is reinforced paper, cardboard, or wood fiber. These fall under Chapter 48.
β οΈ Key Distinction:
- If the primary character is defined by its polymer matrix β Classify under HS 3921.
- If the primary character is defined by its cellulose/paper substrate β Classify under HS 4823.
- Note: Both categories often require high tariffs due to "Section 301" and "Section 122" measures against Chinese-origin goods.
π¦ II. HS Code Classification Details (2026 Latest Tariff Authority)
Based on the provided data, here are the precise classifications for Anti-Static and UV-Resistant Composite Boards:
| HS Code | Product Description | Base Material | Total Tax Rate | Key Characteristics |

- Do not mix these up! Misclassifying a paper-based board as plastic (or vice versa) will lead to severe customs penalties.
π° III. 2026 Latest Tariff Breakdown (Including Surcharges & Policy Levies)
β Applicable Region: United States (US)
β Origin: China (CN)
β Effective Date: Current (Post-2025 Policy Era)
π― 1. 3921.90.50.10 ββ Anti-Static Composite Boards (Plastic Base)
| Item | Detail |
|---|---|
| Basic Tariff | 4.8% (Ad Valorem) |
| Section 301 Surcharge | +25.0% (High Tariff on Chinese Goods) |
| Section 122 Surcharge | +10.0% (Specific Policy Levy) |
| Total Effective Rate | 39.8% |
| Calculation Basis | CIF Value Γ 39.8% |
| De Minimis Exemption? | β NO (Denied) |
| Legal Authority | HTSUS 3921.90.50.10 + Footnotes for Sec. 301 & 122 |
π Analysis:
- This is a high-cost category. The combination of base tariff (4.8%) + Section 301 (25%) + Section 122 (10%) creates a massive barrier to entry.
- Anti-static properties do not exempt you from these surcharges.
π― 2. 3921.90.40.10 ββ UV-Resistant Composite Boards (Plastic Base)
| Item | Detail |
|---|---|
| Basic Tariff | 4.2% (Ad Valorem) |
| Section 301 Surcharge | +25.0% (High Tariff on Chinese Goods) |
| Section 122 Surcharge | +10.0% (Specific Policy Levy) |
| Total Effective Rate | 39.2% |
| Calculation Basis | CIF Value Γ 39.2% |
| De Minimis Exemption? | β NO (Denied) |
| Legal Authority | HTSUS 3921.90.40.10 + Footnotes for Sec. 301 & 122 |
π Analysis:
- Slightly lower than anti-static boards (39.2% vs 39.8%) due to a lower base tariff (4.2% vs 4.8%).
- UV Stabilizers are considered an additive, not a change in fundamental classification, so it remains in Chapter 39.
π― 3. 4823.90.80.00 ββ UV-Resistant Composite Boards (Paper/Cellulose Base)
| Item | Detail |
|---|---|
| Basic Tariff | 0.0% (Ad Valorem) |
| Section 301 Surcharge | +25.0% (High Tariff on Chinese Goods) |
| Section 122 Surcharge | +10.0% (Specific Policy Levy) |
| Total Effective Rate | 35.0% |
| Calculation Basis | CIF Value Γ 35.0% |
| De Minimis Exemption? | β NO (Denied) |
| Legal Authority | HTSUS 4823.90.80.00 + Footnotes for Sec. 301 & 122 |
π Analysis:
- This is the most cost-effective option among the three, with a total rate of 35.0%.
- The zero base tariff is offset entirely by the punitive surcharges.
- Crucial: You must prove the board is primarily cellulose/paper. If itβs plastic-coated paper, customs may still classify it as plastic (3921), increasing your cost.
π οΈ IV. Customs Clearance Practical Advice (Pitfall Avoidance Guide)
β 1. Essential Documentation Checklist (Non-Negotiable)
| Document | Required? | Why? |
|---|---|---|
| β Material Composition Statement | βοΈ | Must explicitly state % of Plastic vs. Cellulose. |
| β Technical Data Sheet (TDS) | βοΈ | Must prove "Anti-Static" (Surface Resistivity Ξ©) or "UV Resistance" (UV Blockage %). |
| β Product Photos (Labeled) | βοΈ | Show texture, layers, and any markings (e.g., "ESD Safe," "UV Protected"). |
| β Commercial Invoice | βοΈ | Clearly describe as "Composite Board," NOT just "Plastic Sheet." |
| β Origin Certificate | βοΈ | Essential for verifying Chinese origin (triggers surcharges). |
| β Packaging List | βοΈ | Show dimensions and weight to verify "Board/Sheet" form factor. |
β 2. Declaration Strategy (Critical Tips)
π₯ Golden Rule: "Material is King, Function is Proof!"
| Scenario | Correct Declaration | Incorrect Declaration | Risk |
|---|---|---|---|
| Plastic Core + Anti-Static | 3921.90.50.10 - "Anti-Static Plastic Composite Board" |
"Plastic Sheet" | Misclassification β Audit/Seizure |
| Plastic Core + UV Stabilizer | 3921.90.40.10 - "UV-Stabilized Plastic Board" |
"Plastic Film" | Rate Discrepancy β Penalty |
| Paper Core + UV Layer | 4823.90.80.00 - "Cellulose-Based UV Composite Board" |
"Plastic Board" | High Rate Application β Overpayment |
| Unknown Base Material | Request Lab Test | Guess "3921" | Customs Rejection β Delay |
β 3. Special Cases & Mitigation
| Situation | Recommendation |
|---|---|
| Multi-Layer Boards | If plastic is just a coating (<50% by weight/volume), argue for 4823. If plastic is the core (>50%), use 3921. |
| OEM Custom Boards | Provide customer specs proving the "Anti-Static" or "UV" function. Generic boards may be rejected if they don't meet technical standards. |
| Small Samples | No De Minimis Exemption! Even for samples under $800, the high tax rate applies. Pay the duty upfront. |
| Supply Chain Shift | If possible, source from Vietnam, Mexico, or Thailand to potentially avoid Section 301/122 tariffs. Check for FTAA/USMCA eligibility. |
π V. Global Market Comparison (2026 Status)
| Region | HS Code | Tariff (China Origin) | Notes |
|---|---|---|---|
| πΊπΈ USA | 3921.90.50.10 / 3921.90.40.10 / 4823.90.80.00 |
35.0% - 39.8% | Highest Barrier: Includes Sec. 301 (25%) + Sec. 122 (10%). No de minimis. |
| π¨π³ China (Export) | N/A | 0% (Export Duty) | No export tax, but production costs + international shipping add up. |
| πͺπΊ EU | Check 3921/4823 | Varies (typically 0-6.5%) | No Section 301/122. Much easier market entry if EU rules of origin are met. |
| π¬π§ UK | Check 3921/4823 | Varies (typically 0-6.5%) | Post-Brexit tariffs are lower than US, but UKCA certification needed. |
π Conclusion:
- The US market is hostile to these specific composite boards due to layered tariffs.
- Cost Optimization: If using plastic,3921.90.40.10(UV) is cheaper than3921.90.50.10(Anti-Static).
- Alternative:4823.90.80.00(Paper-based) is the cheapest route at 35.0%, but requires strict material verification.
π VI. Common Mistakes & Pitfalls (Lessons Learned)
β Mistake 1: Declaring "Plastic Sheet" for an Anti-Static Board
π Result: Customs classifies it as generic plastic (higher base rate) + adds surcharges. Total Rate Could Exceed 40%.
β Mistake 2: Ignoring "Section 122"
π Result: Many importers only account for Section 301 (25%). Forgetting the extra 10% leads to budget shortfalls and payment delays.
β Mistake 3: Confusing "UV-Resistant" with "Anti-Static"
π Result: Using the wrong HS code (3921.90.40.10 vs 3921.90.50.10) causes customs hold-ups for technical verification.
β Correct Action:
Always submit a Technical Data Sheet that explicitly states:
"Surface Resistivity: 10^6 - 10^9 ohms (Anti-Static)"
"UV Blockage: 99% (UV Resistant)"
"Base Material: 100% Polypropylene / Wood Pulp Composite"
π― VII. Final Verdict: Professional Clearance Strategy
π― Summaryε£θ―:
πΉ "Plastic Core? Check 3921. Paper Core? Check 4823."
πΉ "Sec 301 is 25%, Sec 122 is 10%, Add Base Tax, Pay Big."
πΉ "No De Minimis! Samples Pay Too!"
π Pro Tip:
For the lowest total tax rate, consider Paper-Based (4823.90.80.00) if the application allows, as it has the lowest total rate (35.0%). If plastic is mandatory, UV-Resistant (3921.90.40.10) is slightly cheaper (39.2%) than Anti-Static (39.8%).
π£ Immediate Action:
1. Verify material composition (Plastic vs. Paper).
2. Confirm functional specs (Anti-Static vs. UV).
3. Calculate landed cost with 35-40% tax.
4. Engage a licensed US Customs Broker for pre-clearance review to avoid Section 122/301 errors.

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
