MS Storage Tank HS Code for Import & Export (India)

Introduction

Searching the correct HS/HSN code for MS (mild steel) storage tanks helps you file accurate import–export declarations, avoid delays, and estimate duties precisely. Below is a practical, buyer-friendly classification guide for plain storage tanks, jacketed/heated tanks, pressure/gas containers, and tanks combined with mechanical equipment—mapped to their most likely HS headings for Indian Customs (ITC-HS). Use this as a starting point and confirm the 8-digit split with your customs broker for your exact product and use case.

Description

In customs valuation, the principal function and capacity of a tank determine its HS heading. Plain MS tanks meant only for storage are classified differently from process tanks that heat, cool or agitate materials. Capacity threshold (≤300 L vs >300 L) and whether the tank is fitted with mechanical or thermal equipment are key. Gas cylinders/containers fall under a separate heading. The summary table below covers the most common scenarios.

Applications and Benefits

Typical Product Scenario	Likely HS Heading (6-digit)
Plain MS storage tank > 300 L, not fitted with mechanical/thermal equipment (with/without lining or insulation) Plain MS tank ≤ 300 L, not fitted with mechanical/thermal equipment (e.g., drums, small tanks, casks) Containers for compressed or liquefied gas (cylinders, bottles, tanks) of iron or steel Jacketed/heated/chilled process tank where the function is to heat/cool material (thermal treatment) Agitated mixing vessel (mechanical agitator/gearbox; no thermal treatment), individual function as a machine Skid with tank + pump/instrumentation where the pump/process is the principal function	7309 — Reservoirs, tanks, vats, etc., of iron/steel, capacity > 300 L, not fitted with mech/thermal equipment 7310 — Tanks, casks, drums, cans, etc., of iron/steel, capacity ≤ 300 L, not fitted with mech/thermal equipment 7311 — Containers for compressed or liquefied gas (iron/steel) 8419 — Machinery/plant for heating/cooling (thermal treatment of materials), including jacketed vessels 8479 — Machines & mechanical appliances having individual functions (e.g., agitator vessels) 8413 (or other relevant heading) — If the assembly’s principal function is pumping/processing, classify by that function

Typical Product Scenario

Likely HS Heading (6-digit)

Plain MS storage tank > 300 L, not fitted with mechanical/thermal equipment (with/without lining or insulation)
Plain MS tank ≤ 300 L, not fitted with mechanical/thermal equipment (e.g., drums, small tanks, casks)
Containers for compressed or liquefied gas (cylinders, bottles, tanks) of iron or steel
Jacketed/heated/chilled process tank where the function is to heat/cool material (thermal treatment)
Agitated mixing vessel (mechanical agitator/gearbox; no thermal treatment), individual function as a machine
Skid with tank + pump/instrumentation where the pump/process is the principal function

7309 — Reservoirs, tanks, vats, etc., of iron/steel, capacity > 300 L, not fitted with mech/thermal equipment
7310 — Tanks, casks, drums, cans, etc., of iron/steel, capacity ≤ 300 L, not fitted with mech/thermal equipment
7311 — Containers for compressed or liquefied gas (iron/steel)
8419 — Machinery/plant for heating/cooling (thermal treatment of materials), including jacketed vessels
8479 — Machines & mechanical appliances having individual functions (e.g., agitator vessels)
8413 (or other relevant heading) — If the assembly’s principal function is pumping/processing, classify by that function

Key Classification & Documentation Tips

Describe the product clearly: capacity (L), construction (MS), lining/insulation, fittings, and whether any heating/cooling/agitator is present.
State principal function: “storage only” vs “heating/cooling” vs “mixing/processing.” Customs classifies by the essential character.
Attach drawings/spec sheets highlighting absence/presence of coils, jackets, motors, gearboxes, pumps, or controllers.
Declare correct capacity band (≤300 L or >300 L) to distinguish between headings 7310 and 7309.
8-digit ITC-HS: India uses 8-digit splits under the 6-digit HS. Confirm the exact suffix with your CHA for duty notifications.
GST/Invoice HSN: For domestic invoices, use the same 6-digit base; verify the exact 8-digit line for compliance.

Where This Applies

Chemicals & Petrochemicals: Storage tanks for solvents, resins, intermediates (usually 7309/7310 if storage-only).
Food & Pharma: Process vessels with jackets/agitators (often 8419/8479 depending on thermal vs mixing function).
Industrial Gases: Cylinders and gas containers (7311) as distinct from plain storage tanks.

Why This Matters

Correct HS classification prevents fines, demurrage, and re-assessment. It also ensures you claim the right exemptions or preferential duty rates under FTAs. For turnkey projects, classify each item by its own function unless a specific rule requires otherwise.

Uses & Importance

A clear HS mapping for MS storage tanks streamlines import licensing, enables precise landed cost estimation, and improves vendor compliance. Teams can align POs, packing lists, and invoices with the exact 8-digit ITC-HS and reduce queries at the port.

Manufacturer & Supplier Information

Shrinathji Infracon fabricates MS/SS tanks and allied equipment from Ahmedabad, Gujarat. While this page provides a general HS guide, we also share spec-based documentation support—capacity charts, GA drawings, and bill of materials—to help your customs broker select the correct 8-digit line under the applicable 6-digit heading.

FAQs

1. What is the HS code for a plain MS storage tank above 300 litres?

Most plain, storage-only MS tanks >300 L fall under HS 7309 (not fitted with mechanical or thermal equipment). Confirm the 8-digit ITC-HS split from the current tariff.

2. Which code covers small MS tanks and drums up to 300 litres?

Typically HS 7310 for iron/steel containers ≤300 L that are not fitted with mechanical or thermal equipment.

3. How to classify jacketed or heated/chilled tanks?

If the tank’s principal function is thermal treatment (heating/cooling), it generally falls under HS 8419.

4. What about tanks with agitators for mixing?

Agitated vessels without thermal treatment usually classify as machines with an individual function under HS 8479.

5. Gas cylinders or gas storage containers are under which chapter?

They are typically covered by HS 7311 (containers for compressed or liquefied gas, of iron or steel).

Conclusion

For MS storage tank HS codes, start with 7309 (>300 L, storage-only) or 7310 (≤300 L, storage-only). Move to 8419 for jacketed/heated tanks and 8479 for agitated vessels. Gas containers are 7311. Always align your 8-digit ITC-HS with current notifications and consult your CHA for the precise suffix.
