π HS Code Reference & Customs Clearance Guide | 2026 Latest Tariff Analysis | Professional-Level Compliance Strategy
π Part I: Product Definition & Classification: What Exactly Are "Sterilizer Granules"?
Sterilizer Granules are solid, granular chemical agents used to eliminate pathogens (bacteria, viruses, fungi, and spores) in industrial water systems, agricultural soil, food processing equipment, or medical instrument sterilization cycles. Unlike liquids or gases, their granular form allows for controlled dosing, storage, and transport.
In international trade, they are classified based on their active chemical ingredient and primary intended use. Misclassification is the most common cause of clearance delays for this category.
β οΈ Key Distinction Points:
- Chlorine-based granules (e.g., Trichloroisocyanuric acid) β Used for water treatment/disinfection β HS 2828 or 3808
- Oxygen-based granules (e.g., Sodium dichloroisocyanurate) β Broad-spectrum disinfectant β HS 3808
- Glutaraldehyde/Peracetic acid granules β Medical/surgical sterilization β HS 3004 (if medicated) or 3808 (if industrial)
- Ethylene Oxide (EtO) derived solids β Rare as granules; usually gas β HS 2915 or 2916 (if precursor)
π¦ Part II: HS Code Classification Details (2026 Latest Tariff Authorityε―Ήη §)
| HS Code | Product Description | Primary Use Case | Active Ingredient Type |
|---|---|---|---|
2828.90.00.00 |
Chlorine salts & chloride oxides, other than perchlorates | Water treatment granules (pool, industrial) | Inorganic Chlorine (e.g., Sodium Hypochlorite solids) |
3808.91.10.00 |
Insecticides, rodenticides, fungicides, herbicides, disinfectants & similar products (for disinfection) | General-purpose disinfectant granules (agricultural/industrial) | Organic/Inorganic Disinfectants (e.g., Trichloroisocyanuric acid) |
3808.94.00.00 |
Disinfectants, not specified elsewhere (for disinfection) | Specialized industrial sterilants | Complex organic mixtures |
3004.90.99.00 |
Medicaments (including mixed or unmixed) for therapeutic or prophylactic uses | Medical instrument sterilization (if labeled as therapeutic aid) | Glutaraldehyde, Peracetic acid (if classified as medical device/medicament) |
2915.21.00.00 |
Acetic acid & acetates, unsaturated | Precursors for sterilant synthesis | Chemical intermediate (not final sterilant) |
π Critical Reminder:
- Disinfectants for general use (not medical/therapeutic) almost always fall under Chapter 38 (3808).
- Medical-grade sterilizers intended to prevent disease in humans/animals may fall under Chapter 30 (3004), but only if explicitly registered as a medicament.
- Water treatment granules (e.g., for pools) are often 2828 if inorganic chlorine, or 3808 if organic chlorine.
- Do NOT classify as "Chemical Products" vaguely. Specificity is required.

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
