💰 III. 2026 Latest Tariff Rate Breakdown (Including Surcharges)
✅ Applicable Country: United States (US)
✅ Origin: China (CN)
✅ Effective Date: Post-November 10, 2025
🎯 1. Classification as Non-Woven Fabric (5603.94.90.70 / 5603.94.90.90)
Why this matters: This classification offers the lowest total tariff burden.
| Item | Detail |
|---|---|
| Base Duty Rate | 0.0% |
| USITC Surcharge (Section 301) | +25.0% |
| IEEPA Surcharge (122 Clause) | +10.0% |
| Total Effective Tax Rate | 35.0% |
| Calculation | CIF Value × 35.0% |
| De Minimis Exemption? | ❌ No (High risk of seizure/confiscation if shipped via small parcel) |
| Legal Basis | USITC:5603.94.90.70 → FOOTNOTE:9903.88.01 (25% surcharge) + IEEPA:9903.01.25 (10% surcharge) |
📌 Explanation:
- The 0% base rate makes this the preferred classification if the product can be convincingly argued as a "non-woven fabric" rather than just "activated carbon."
- However, the 25% + 10% = 35% surcharge is unavoidable for Chinese origin goods in this category.
🎯 2. Classification as Activated Carbon (3802.10.00.10 / .20 / .50)
Why this matters: This classification results in a higher total tax burden.
| Item | Detail |
|---|---|
| Base Duty Rate | 4.8% |
| USITC Surcharge (Section 301) | +25.0% |
| IEEPA Surcharge (122 Clause) | +10.0% |
| Total Effective Tax Rate | 39.8% |
| Calculation | CIF Value × 39.8% |
| De Minimis Exemption? | ❌ No |
| Legal Basis | USITC:3802.10.00.xx → FOOTNOTE:9903.88.01 (25% surcharge) + IEEPA:9903.01.25 (10% surcharge) |
📌 Explanation:
- Even though the base duty is only 4.8%, the additional surcharges push the total to 39.8%.
- This classification is used when customs authorities determine the primary identity of the goods is "Activated Carbon" (a chemical/adsorbent) rather than a "Textile."
🛠️ IV. Clearance Practical Advice (Avoiding Pitfalls)
✅ 1. Required Documentation Checklist
| Document | Mandatory? | Purpose |
|---|---|---|
| ✅ Product Specification Sheet | ✔️ | Must detail: Material composition (Bamboo Carbon Fiber %), thickness, density, and manufacturing process (Spunlace/Thermal Bonded). |
| ✅ Technical Data Sheet (TDS) | ✔️ | Prove adsorption capacity (Iodine value, etc.) vs. physical structure (Non-woven structure). |
| ✅ Photos (Clear Labeling) | ✔️ | Show the "Felt" texture. If it looks like a flexible mat, argue for 5603. If it looks like granular carbon pressed into a shape, argue for 3802. |
| ✅ Commercial Invoice | ✔️ | Clearly state: "Bamboo Activated Carbon Felt, Non-woven Fabric, for Air Filtration." Avoid vague terms like "Activated Carbon Block." |
| ✅ Supply Chain Proof | ✔️ | Evidence of how it was made (e.g., carbonization of bamboo fibers → spinning → non-woven web formation). |
✅ 2. Declaration Strategy (Crucial Tips)
🔥 Golden Rule:
"Structure defines the Code: Non-woven structure = 5603. Chemical adsorption = 3802."
| Scenario | Recommended HS Code | Reasoning |
|---|---|---|
| Flexible, fabric-like, used in filters | 5603.94.90.70 or .90 |
Emphasize "Non-woven Fabric" properties. It is a structural textile made of carbon filaments. |
| Rigid, block-like, or granular-pressed | 3802.10.00.xx |
If it lacks textile structure and is purely for adsorption, it is treated as Activated Carbon. |
| OEM Custom Felt | 5603.94.90.70 |
Provide customer design specs showing it is a "fabric" component. |
⚠️ Warning:
- Do NOT claim "De Minimis" exemption for this product. The total tax (35% or 39.8%) exceeds the $800 threshold implication, and customs may seize packages if misdeclared as low-value goods. - Ensure the invoice description matches the HS code. If you declare5603, do not call it "Activated Carbon Block" in the description. Call it "Carbon Fiber Non-woven Fabric."
✅ 3. Special Cases
| Situation | Advice |
|---|---|
| Mixed Materials (e.g., Cotton + Bamboo Carbon) | If the bamboo carbon is the primary functional material (>50%), stick to carbon-related codes. If it's just a coating, 5603 is safer. |
| Export to US via Third Country | Re-export Risk: If processed in Vietnam/Malaysia, prove substantial transformation. Simple packaging/packing does not change origin. |
| Pre-Ruling Application | Highly Recommended: Submit an Advance Ruling to US CBP with product samples and technical sheets. This locks in the 35% rate and avoids post-clearance audits. |
🌍 V. Global Market Comparison (2026 Context)
| Region | Recommended HS Code | Est. Tariff (China Origin) | Key Requirement |
|---|---|---|---|
| 🇺🇸 USA | 5603.94.90.70 |
35.0% | High scrutiny on "Non-woven" vs "Carbon". |

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
