π I. Product Definition & Classification: Do You Really Understand "Aquarium Tanks"?
Aquarium fish farming tanks, often referred to as Aquaculture Systems or Recirculating Aquaculture Systems (RAS) components, are specialized containers used for breeding, holding, or transporting aquatic organisms. In international trade, these are not classified as simple consumer goods (like home aquariums under heading 9503). Instead, they are classified as industrial or agricultural machinery parts/containers, primarily based on their material, function, and capacity.
β οΈ Key Distinction Point:
- If the tank is a standalone plastic container with a capacity >300L, used for storage/farming β Likely 3925.10.00.00 or 3926.90.99.89.
- If the tank is part of a filtration/purification system (including pumps, filters, UV sterilizers) β Likely 8421.99.01.80 (Parts of filtering machinery).
- If the tank is made of Iron/Steel and is for household/kitchen use (rare for farming) β 7323 (But unlikely for professional fish farming).
π¦ II. HS Code Classification Details (2026 Latest Tariff Authority Comparison)
Based on the provided , here are the specific HS Codes applicable to different types of Aquarium Fish Farming Tanks:
| HS Code | Product Description | Applicable Scenario | Material/Type | Tax Rate (Total) |
|---|---|---|---|---|
3925.10.00.00 |
Builders' ware of plastics: Reservoirs, tanks, vats and similar containers, of a capacity exceeding 300 liters | Large-scale plastic fish farming tanks, industrial aquaculture reservoirs | Plastic, Capacity >300L | 0.0% |
3926.90.99.89 |
Other articles of plastics: Other | Smaller plastic aquarium components, accessories, non-reservoir plastic parts | Plastic, Non-reservoir | 0.0% |
8421.99.01.80 |
Centrifuges...; Filtering or purifying machinery...: Parts: Other Other | Parts of filtration systems (pumps, filter housings, centrifugal dryers) used in fish farming | Mechanical/Electrical Parts | 25.0% |
7323.91.50.40 |
Table, kitchen... articles... of cast iron...: Of cast iron, not enameled | (Unlikely) Cast iron tanks for household use | Cast Iron | 5.3% |
7323.94.00.80 |
Table, kitchen... articles... of iron or steel, enameled Other | (Unlikely) Enamelled steel tanks | Steel/Enamelled | 50.0% |
π Important Note:
- Plastic Tanks (>300L): The most common classification for industrial fish farming tanks. Tax is 0%.
- Filtration System Parts: If the "tank" includes integrated filtration units (e.g., a filter housing made of metal/plastic but classified as a machine part), it may fall under 8421.99.01.80. Tax is 25%.
- Avoid 7323: Household iron/steel articles are not appropriate for professional fish farming tanks unless they are specifically designed as such (which is rare and usually incurs high taxes).

π οΈ IV. Customs Clearance Practical Advice (Pitfall Avoidance Guide)
β 1. Documentation Checklist (Mandatory)
| Document | Must Provide | Description |
|---|---|---|
| β Product Specification Sheet | βοΈ | Include dimensions, capacity (liters/gallons), material (PP, PE, FRP), and intended use (Aquaculture/Fish Farming). |
| β Material Composition | βοΈ | Specify if plastic (PP/PE), stainless steel, or fiberglass. Crucial for HS Code determination. |
| β Capacity Declaration | βοΈ | Critical: Must clearly state if capacity is >300L or β€300L. This determines if it falls under 3925.10.00.00 or 3926.90.99.89. |
| β Commercial Invoice | βοΈ | Clearly describe as "Plastic Fish Farming Tank, 500L Capacity, No Electrical Components." Avoid vague terms like "Container." |
| β Photos (Labeled) | βοΈ | Show full tank, label with model/capacity, and any connections (inlet/outlet). |
| β Bill of Lading/Air Waybill | βοΈ | Ensure weight and dimensions match commercial invoice. |
β 2. Declaration Tips (Key Principles)
π₯ "Capacity Matters, Material Defines Code, Function Clarifies Rate!"
| Scenario | Correct HS Code | Error to Avoid |
|---|---|---|
| Plastic tank, >300L, no machinery | 3925.10.00.00 (0%) |
Misclassifying as 8421 (25%) if it has no filter/pump. |
| Plastic tank, β€300L, accessory | 3926.90.99.89 (0%) |
Misclassifying as 3925.10.00.00 (capacity error). |
| Tank with integrated pump/filter | 8421.99.01.80 (25%) |
Declaring as 3925 if it contains functional machinery parts. |
| Steel household basin (not for fish) | 7323.94.00.80 (50%) |
Using this for fish tanks β 50% tax + reclassification risk. |
β 3. Special Considerations
| Situation | Handling Advice |
|---|---|
| Importing a Complete System (Tank + Filter + Pump) | Declare as a single unit. If the primary function is filtration, consider 8421. If primarily storage, use 3925. Consult a broker for "essential character" determination. |
| Fiberglass (FRP) Tanks | Classify under 3926.90.99.89 if β€300L, or 3925.10.00.00 if >300L (as plastic-like builders' ware). |
| Stainless Steel Tanks | If not for household use, check Chapter 73. If it's a container, it may fall under 3925 if made of plastic-lined steel, or 7323 if purely steel. High tax risk for steel. |
| Used Tanks | Must declare as "Used." Some countries restrict used aquaculture equipment due to biosecurity. Check APHIS/USDA regulations. |
π V. Global Market Comparison (2026)
| Country/Region | Recommended HS Code | Tariff | Certification | Notes |
|---|---|---|---|---|
| πΊπΈ USA | 3925.10.00.00 |
0% | None | Best for large plastic tanks. |

| π¨π³ China | 3925.10.00.00 |
5-10% | None | Import duties vary. |
| π―π΅ Japan | 3925.10.00.00 |
0% | JIS | Low tariffs for plastic. |
π Conclusion:
- USA offers 0% tariff for large plastic aquaculture tanks (3925.10.00.00).
- Avoid steel tanks if possible due to 50% surcharges.
- Plastic is the optimal material for cost-effective import.
π VI. Common Errors & Pitfall Guide
β Error 1: Declaring a 500L plastic tank as 3926.90.99.89 (β€300L category).
π Consequence: Incorrect classification, potential penalty, or demand for back taxes.
β
Fix: Ensure capacity is clearly stated as >300L for 3925.10.00.00.
β Error 2: Including a pump in the same package but declaring only as a "Plastic Tank."
π Consequence: Customs may classify the entire package as machinery (8421) β 25% tax.
β
Fix: Separate shipments or declare the primary function. If the tank is the main component, argue for 3925. If the pump is essential, consider 8421.
β Error 3: Using "Aquarium" as the description.
π Consequence: Customs may think it's a consumer toy (9503) β Misclassification.
β
Fix: Use "Plastic Aquaculture Tank, Industrial Use, 500L".
π― VII. Conclusion: Smart Importing, Lower Costs!
π― Remember:
πΉ "Plastic >300L = 0% Tax (
3925.10.00.00)"
πΉ "Machinery Parts = 25% Tax (8421.99.01.80)"
πΉ "Steel Household = 50% Tax (7323.94.00.80)"π Pro Tip:
If your tank includes a filtration system, consider importing the tank and filter separately.
- Tank:3925.10.00.00(0%)
- Filter Parts:8421.99.01.80(25%)
This may allow you to optimize logistics, but consult a customs broker to ensure compliance.

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
