Check valves are indispensable elements in automotive, plumbing and industrial equipment systems that prevent the reverse flow of liquids or gases. However, when importing or exporting them, many encounter a problem: what HS code to indicate in the declarationto avoid customs delays or fines? An error in classification can result not only in financial losses, but also in confiscation of goods.

In 2026, an updated version of the Commodity Nomenclature of Foreign Economic Activity (TN FEACN of the EAEU) is in effect, where check valves are distributed into several groups depending on material of manufacture, appointments and technical characteristics. For example, a valve for a car's fuel system and a valve for a water supply system will have different codes, despite the similar principle of operation. In this article we will look at current HS codes for check valves, the nuances of their classification and typical mistakes that declarants make.

What is the HS and why is the correct code for a check valve important?

TN VED (Commodity Nomenclature for Foreign Economic Activity) is a system of classification of goods used by the customs services of the EAEU countries to determine duties, taxes and restrictions when crossing the border. Each product is assigned a unique digital code consisting of 10 characters. For check valves, the code depends on:

  • 🔧 Housing material (steel, brass, plastic, cast iron)
  • 🚗 Areas of application (automotive, plumbing, industrial)
  • 📏 Connection size and type (threaded, flanged, coupling)
  • 💨 Type of working environment (water, gas, fuel, chemicals)

Incorrectly specified code can lead to:

  • ⚠️ Inflated duties (if the product is classified in a more expensive category)
  • ⏳ Delay at customs for 10–30 days to clarify the classification
  • 💰 Fines up to 50% of the cost of the goods (according to Article 16.2 of the Code of Administrative Offenses of the Russian Federation)
💡

Before completing your declaration, please request technical passport on the check valve - it must indicate the material, operating pressure and purpose. This data will help to more accurately determine the HS code.

Main HS codes for check valves in 2026

Check valves are classified into section XVI TN VED (“Machines and mechanisms; electrical equipment”), mainly in group 84 (“Nuclear reactors, boilers, machines and mechanical devices”). Below is a current list of codes with examples:

HS Code Description Application examples
8481 80 100 0 Check valves for pipelines, made of ferrous metals Water supply, heating, industrial systems
8481 80 310 0 Check valves made of non-ferrous metals (brass, bronze) Plumbing, air conditioning systems
8481 80 500 0 Check valves made of plastic Household filters, irrigation systems
8409 91 900 0 Pump parts (including check valves for fuel systems) Automotive fuel lines, diesel engines
8481 30 000 0 Valves for gas equipment Gas boilers, industrial furnaces

Important: if the check valve is part of a kit (for example, for repairing a car injector), it may be classified according to the main product code (for example, 8708 99 900 0 - “other parts for engines”). Check this with your customs broker in advance.

Check valves for cars: classification nuances

In the automotive industry, check valves are used in fuel systems, vacuum brake boosters and crankcase ventilation systems. Their classification depends on:

  • 🔩 Installation locations:
    • There is a code in the fuel pump 8413 30 900 0 (“fuel pump parts”)
    • In the gas recirculation system (EGR) - code 8409 91 900 0
  • 🔋 Engine type:
    • For diesel engines - often classified as 8409 91 900 0
    • For gasoline engines - may fall under 8708 99 900 0 (“other parts”)

Case Study: Check Valve Bosch 0 280 142 017 for fuel system VW Golf was incorrectly declared as "plumbing" (8481 80 100 0), which led to an additional duty of 12% of the cost of the shipment. The correct code for this case is 8413 30 900 0.

What happens if you enter the wrong code for the auto valve?

Customs may require disassembly of the party for examination, which takes up to 20 days. In 30% of cases, the goods are recognized as “incorrectly declared” and are returned to the sender at his expense.

Typical mistakes when choosing a HS code and how to avoid them

According to the Federal Customs Service of Russia, 23% errors in the declaration of check valves are associated with an incorrect definition of the material or purpose. Let's look at the most common mistakes:

  1. Confusion between "plumbing" and "industrial" valve

    Valve for water supply (8481 80 100 0) and valve for the chemical industry (8481 80 900 0) may be identical in appearance, but have different codes due to working environment.

  2. Ignoring configuration

    If the valve comes as part of a set (for example, with a filter), it may be classified as a “part” of the main product, and not as an independent product.

  3. Failure to take into account the country of origin

    For valves from China and EAEU countries, different rules for confirming origin apply (for example, a Form “A” certificate for preferential duties).

Specify the body material (passport/labeling)|Check the purpose (plumbing/automotive/industrial)|Check the code with the latest changes in the Commodity Code of Foreign Economic Activity (2026)|Consult with a customs broker-->

⚠️ Attention: If the technical documentation states “for drinking water”, but the valve is made of brass with a lead content of >2%, it cannot be declared as 8481 80 310 0. A certificate of conformity TR CU 017/2011 (“Safety of paint and varnish products”) is required!

How to confirm the HS code: documents and examination

For trouble-free customs clearance, prepare the following package of documents:

  • 📄 Technical data sheet indicating:
    • Material (for example, “brass LS59-1”)
    • Working pressure (for example, "PN 16")
    • Connection type (thread G1/2", flange DN50)
  • 🔍 Conclusion on classification (can be requested from the manufacturer or Standardization Center)
  • 📑 Contract with supplier, where the purpose of the product is indicated

If customs doubts the code, it can initiate commodity examination (cost - from 15,000 ₽). To avoid this:

  1. Ask the manufacturer letter of clarification about the purpose of the valve.
  2. Compare your product with EEC decisions on classification (eg Decision No. 112 of 2023 on valves for gas systems).
💡

If the check valve has unique design (e.g. electromagnetic drive), it may be classified as "other" (8481 80 900 0) with increased duty. In this case, an Advance Ruling from Customs (CAC) is required.

Duties and benefits: how much does it cost to import check valves in 2026

Import duty rates on check valves depend on HS code and country of origin. Current rates (according to EEC data as of June 2026):

HS Code Country of origin Duty (%) Benefits/exceptions
8481 80 100 0 China 10% —
8481 80 310 0 Germany 5% Benefit under the EAEU-EU agreement
8409 91 900 0 Japan 0% LNG benefit with Japan
8481 80 500 0 Türkiye 6,5% —

To reduce duties you can:

  • 🌍 Use preferential agreements (for example, with Serbia or Vietnam).
  • 🔄 Checkout customs processing procedure (if the valves will be used in production on the territory of the EAEU).
  • 📦 Break the batch into small items (up to 1000 €) to apply discounts postal items.
⚠️ Attention: When importing check valves from China via Almaty or Nur-Sultan (Kazakhstan), additional requirements on labeling in Russian (TR TS 004/2011). Without it, the goods will not be allowed to pass beyond the customs union.

FAQ: Frequently asked questions about HS codes for check valves

Is it possible to use the code 8481 80 100 0 for stainless steel valve?

No. Stainless steel valves belong to subheading 8481 80 200 0 (“alloy steel”). Specifying the code 8481 80 100 0 (for ferrous metals) will lead to additional duties.

Is certification required for check valves in automotive fuel systems?

Yes. Valves for fuel systems must comply TR TS 018/2011 (“On the safety of wheeled vehicles”). A certificate or declaration of conformity will be required.

How to classify a motorized check valve?

These valves are 8481 80 900 0 (“other”) or 8536 50 000 0 (“electrical control apparatus”). The exact code depends on the main function: if the electric drive is auxiliary - 8481, if the main one is 8536.

What to do if customs does not agree with the selected code?

You have the right:

  1. Provide additional documents (letter from manufacturer, expert opinion).
  2. Challenge the customs decision Federal Customs Service of Russia or court (the appeal period is 3 months).
  3. Request preliminary decision on classification (PRT) before importation of goods.
What fines are imposed for an incorrect HS code?

According to Art. 16.2 Code of Administrative Offenses of the Russian Federation:

  • For misclassification — a fine from 50% to 100% of the amount of arrears of duty.
  • For deliberate understatement cost - fine up to 200% + confiscation of goods.

For the first violation, you can get off with a warning if the error did not lead to an understatement of duties.
