π‘οΈ Mold Prevention Spray (Antimicrobial & Fungicide Sprays)
π HS Code Reference & Customs Clearance Guide | 2026 Latest Tariff Analysis | Professional Compliance Strategy
π Part 1: Product Definition & Classification β Do You Really Understand "Mold Spray"?
Mold prevention sprays are complex chemical formulations designed to inhibit fungal growth on surfaces. In international trade, they are not classified as a single item. Their HS Code depends entirely on their primary function and chemical composition.
There are two main categories:
1. Disinfectants & Fungicides (Chemical/Biological Action):
Products that kill or inhibit mold through chemical agents (e.g., quaternary ammonium compounds, hypochlorites, isothiazolinones). These are primarily classified as chemical products.
2. Air Care/Fresheners (Physical/Olfactory Action):
Products that mask odors or provide a "fresh" scent with negligible antimicrobial efficacy. These are classified as perfumery/cosmetic products.
β οΈ Critical Distinction Point:
- If the label claims "Kills 99.9% of Mold/Mildew" or lists specific fungicidal active ingredients β It is a Disinfectant/Fungicide (Chapter 38).
- If the label only claims "Deodorizes," "Fresh Scent," or lacks specific antifungal claims β It is a Perfume/Cosmetic (Chapter 33).
- Note: Even if it has a scent, if the primary purpose is disinfection, it falls under Chapter 38.
π¦ Part 2: HS Code Classification Details (2026 Latest Tariff Authority Comparison)
| HS Code | Product Description | Application Scenario | Primary Function | Regulatory Body |
|---|---|---|---|---|
3808.93.10.00 |
Insecticides, rodenticides, fungicides, herbicides... (Other) | Mold sprays with fungicidal active ingredients (e.g., chlorine-based, quats) | Kill/Inhibit Fungi | EPA (US) |
3307.90.00.00 |
Preparations for deodorizing rooms or other places... | Air fresheners with mild antimicrobial additives but no specific claim | Mask Odor / General Hygiene | FDA (US) |
3808.94.00.00 |
Biocidal products (Under EU/EPC regulations) | Specific biocidal products for disinfection | Disinfection | EPA/ECHA |
3304.99.00.00 |
Beauty or makeup preparations | Skincare/makeup (Not applicable for mold spray, listed for exclusion) | N/A | FDA |
3808.91.10.00 |
Insecticides (Not applicable) | Insect repellents | Kill Insects | EPA |
π Key Reminder:
- Most commercial/industrial mold sprays fall under3808.93.10.00because their primary function is fungicidal.
- If the product is marketed as a "Laundry Sanitizer" or "Surface Disinfectant" that also kills mold, it is still3808.93.10.00.
- Do NOT classify mold sprays as3307(deodorizers) unless they lack any antifungal claims and are purely for scent. This is a common misclassification error leading to penalties.

- "USITC Surtax 25%": From the U.S. Trade Act Section 301, targeting Chinese chemical products.
- "IEEPA 10%": The new International Emergency Economic Powers Act surcharge for Chinese goods.
- Total 35%: This is a high tariff. Unlike electronics, there is no "essential item" exemption for fungicides.
- No De Minimis: Shipments under $800 (Section 321) are NOT exempt from these surtaxes if the HS code is listed in the exclusion list.
π― 2. 3307.90.00.00 β Deodorizing Preparations (If Misclassified or Purely Scented)
| Item | Content |
|---|---|
| Base Tariff Rate | 0% |

| IEEPA Surtax | +10% |
| Total Tariff Rate | 17.5% (Approximate) |
| Tax Calculation | CIF Γ 17.5% |
| De Minimis Exemption Eligibility | β οΈ Complex (Depends on specific footnote; often subject to scrutiny if disguised as disinfectants) |
π Warning:
- If you declare a mold-killing spray as "Room Deodorizer" (3307) to save taxes, Customs (CBP) will likely reject it if the SDS (Safety Data Sheet) shows fungicidal properties.
- Penalty: Re-classification, back-tariffs, and potential fraud allegations.
π οΈ Part 4: Customs Clearance Practical Advice (Combat Pitfalls Guide)
β 1. Document Preparation Checklist (None Can Be Missing)
| Document | Mandatory? | Description |
|---|---|---|
| β SDS (Safety Data Sheet) | βοΈ | Most Critical. Must clearly list "Fungicidal Activity" and active ingredients (e.g., Quaternary Ammonium Compounds). |
| β EPA Registration Number | βοΈ | Required for 3808.93.10.00. The product must be registered with the U.S. EPA. |
| β Product Label Photo | βοΈ | Must show "Kill Claims" (e.g., "Kills Mold & Mildew"). |
| β Formula Composition | βοΈ | Breakdown of active and inert ingredients by percentage. |
| β Commercial Invoice | βοΈ | Must state "Fungicidal Spray" or "Mold Inhibitor," not just "Spray." |
| β COO (Certificate of Origin) | βοΈ | Essential for calculating IEEPA and Section 301 duties. |
β 2. Declaration Tips (Key Mantra)
π₯ βActive Ingredients Decide, EPA Reg Number is Key!β
| Scenario | Correct Declaration | Wrong Practice |
|---|---|---|
| Spray kills mold (Chemical) | 3808.93.10.00 + EPA Reg No. |
Declare as 3307.90.00.00 (Deodorizer) β Audit Risk |
| Spray masks odor (No kill claim) | 3307.90.00.00 |
Declare as 3808.93.10.00 β Overpay Tariffs |
| Liquid concentrate | 3808.93.10.00 |
Declare as "Cleaning Solution" without specifying function β Delay |
| Packaged with Applicator | Include in Gross Weight | Split declaration β High Risk of Seizure |
β 3. Special Case Handling
| Situation | Handling Advice |
|---|---|
| EPA Exempt (Minimum Risk) | If the product uses only "minimum risk" ingredients (e.g., citrus oil, soap), it may not need EPA registration. However, it must be explicitly declared as such. Tariff may still apply. |
| Bio-based/Fungal Extracts | If derived from natural sources (e.g., thyme oil), check if it qualifies for 3301 (Essential Oils) or 3808. Usually, if marketed as a disinfectant, it stays in 3808. |
| Laundry Sanitizer | Often falls under 3808.93.10.00. Ensure label supports "Sanitize/Kill" claims. |
| Shipments under $800 (De Minimis) | β οΈ Caution: 3808.93.10.00 is often excluded from Section 321 de minimis for China-origin goods due to Section 301. Do not assume duty-free. |
π Part 5: Global Market Comparison (2026 Latest)
| Country/Region | Recommended HS Code | Tariff | Certification | Remarks |
|---|---|---|---|---|
| πΊπΈ USA | 3808.93.10.00 |
35% (China) | EPA Registration Mandatory | Strict enforcement on kill claims. |
| πͺπΊ EU | 3808.94.00 |
0-4% | Biocidal Products Regulation (BPR) | Requires EU Biocidal Approval. |
| π¬π§ UK | 3808.94.00 |
0-4% | GB BPR | Post-Brexit UK-specific approval. |
| π¨π³ China | 3808.93.10 |
5% | Pesticide Registration | High import duty, requires Chinese EPA. |
| π¨π¦ Canada | 3808.93.00 |
0% | PMRA Registration | Free trade (CUSMA) if Canadian origin. |
π Conclusion:
- USA & EU have strict chemical regulations. No registration = No entry.
- USA Tariffs are high (35%). Consider supply chain diversification if margins are thin.
- EU BPR is more complex than EPA but may offer lower tariffs.
π Part 6: Common Errors & Pitfalls (Lessons Learned)
β Error 1: Declaring "Mold Spray" as "Cleaning Spray" (3808.94.00 vs 3808.99.00)
π Consequence: Incorrect tariff rate, potential customs query.
β Error 2: Omitting the EPA Registration Number on the invoice
π Consequence: Refusal of Entry (Refuse) by CBP. Product held or destroyed.
β Error 3: Using "Deodorizer" for a product that kills mold
π Consequence: Customs may impose fraud penalties for misdeclaration. Tariff difference + fines.
β Error 4: Assuming De Minimis ($800) applies to all small packages
π Consequence: Seizure. Section 301 surtaxes often negate de minimis benefits for chemical goods from China.
β Correct Practice:
"Fungicidal Spray, EPA Reg No. [12345-67], Active Ingredient: Quaternary Ammonium Compounds (1.5%), For Surface Mold Prevention, Model XYZ, SDS Attached."
π― Part 7: Conclusion β Compliance Saves Money!
π― Remember the Mantra:
πΉ βKill Claim = 3808 + EPA + 35% Dutyβ
πΉ βScent Only = 3307 + Lower Dutyβ
πΉ βNo EPA = No Entryβ
πΉ βDe Minimis Not Always Free for Chemicalsβ
π Pro Tip:
If your mold spray is essential for healthcare or industrial use, check for exclusion lists under Section 301. Some specific chemical formulations may have exclusions, but this requires an active application process.
π£ Immediate Action:
π Verify EPA Registration with your supplier.
π Obtain the latest SDS and Label.
π Apply for CBP Ruling if uncertain about classification.

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
