What Is All The Fuss About

Beyond your shipping costs alone is the question of “What is the total cost of getting products to India?” Understanding “how is customs duty calculated in India” in advance of preparing your shipment helps anticipate your costs, avoids customs delays during processing, and ensures you're gathering the required paperwork. If you're importing household items, commercial freight, personal cargo, or any other goods into India, familiarising yourself with “customs duty calculation” can save you money.


What is Customs Duty in India?

For those who have asked “what is customs duty in India?”, it's simply a tax levied by India's Customs Department on the arrival of products into the nation. Each shipment destined for India goes through a “customs tariff India” classification process prior to release and delivery.

This process takes into account:

  • What product is shipped
  • Its worth
  • Its nation of origin
  • Applicable import laws

Along with its goal of protecting domestic industries, customs duties are a revenue-generating activity.


HS Code

Everything imported has its own “HS code”, also referred to as “HSN code.” The specific “HS Code For International Shipping” identifies a shipment’s classification.

It also gives insight into:

  • The duty that the product will pay
  • Any required licences
  • Any import restrictions or limitations
  • If IGST would be applied
  • Details concerning Customs

Choosing the correct “HS code import duty in India” will ensure correctly levied duties and prevent a delay.


Shipping Documents

The Indian Customs authority must review various papers before clearance of imported products.

Typical documents required for customs clearance include:

  • Commercial invoice
  • Packing list
  • Bill of lading or Air Waybill
  • Customer identification information
  • IEC code (if relevant)
  • “Shipping invoice for customs”
  • Bill of entry

There is often a concern over what documents are required for customs clearance in India?


Bill Of Entry

To the Indian Customs, a “bill of entry” is given by importers to show details of an incoming shipment, including:

  • Importing party information
  • Description of goods shipped
  • Quantity
  • HS code of the imported item
  • Total customs value

“A Bill of Entry” is utilised by officials to calculate taxes that are due on your goods, and approve the shipment’s departure from customs.


The Process of Customs Duty Calculation

“How is customs duty calculated in India?”

The procedure entails much more than simply multiplying your product’s base cost by a duty rate. The “customs duty calculation” involves other factors besides “basic customs duty”.

Several components of “customs duty calculation India” come into play, which we outline below.


Customs Duty Calculation Formula

Importers often ask: “customs duty calculation formula”, or “how to calculate customs duty”, to determine shipment costs before ordering products in India.

The “customs duty calculation formula” is typically in the order listed below:

  • First step: calculate “customs valuation”
  • Second, add in the shipping and insurance charges to the customs valuation for the landing costs
  • Apply duty rates as listed in “customs tariff India” to obtain “basic customs duty”
  • Calculate “social welfare surcharge”
  • Determine any and all “integrated GST”, if it applies
  • Add in any other specified customs duties

Calculation of customs duty in India proceeds as far as “calculation of import duty in India”.


Customs Valuation Method

You can't calculate customs duties and related taxes in India without properly measuring “customs valuation.”

Indian Customs commonly utilises the customs valuation methodology by using "transaction value," which entails:

  • Product Value
  • Transport Costs (Shipping Costs)
  • Insurance Policies

“Customs valuation method” is utilized to ensure all necessary import duties are paid.

Calculating customs valuation correctly helps avoid issues during the import procedure.


Basic Customs Duty

A “basic customs duty”, also known as “BCD”, is simply a tax collected on items imported into India.

The particular “HS code” will determine not only the exact rate, but additionally the relevant policy. The country of origin, in addition to current trade pacts, also contribute to duty rates.

Thus, it is crucial that you obtain correct import tariff information from your “customs tariff India”, prior to placing an order.


Social Welfare Surcharge

Any number of imports into India may also incur a “social welfare surcharge”.

Typically calculated using the basic customs duty (BCD), this surcharge forms part of an importer's total customs payments.


Integrated GST (IGST)

Once basic and any additional customs taxes have been determined, Indian customs may also apply “integrated GST” (IGST) to a shipment’s overall costs.

IGST also factors into calculating your “landed cost of imported goods in India”.

When determining the whole landed cost, you'll want to consider both import duties as well as the relevant “integrated GST”.


Importing Products To India

The rate varies from one product to the next and depending on your region of origin from which you are importing.

The “import duty rate in India” will be shown based on what specific “import duty tariff in India” was created to serve the HS Code of those products.


Customs Clearance Charges

For those shipments going to India, we know what all customs clearance expenses, if applicable, including local customs costs, carrier's transport fees, customs brokerage fees, storage costs at the port, and other clearance-related fees may occur with a shipment entering India.


Import Duty-Free Allowance

Those wishing to bring personal effects or small purchases to India may potentially be entitled to a “duty-free allowance.”

This will depend on:

  • Passenger’s baggage regulation
  • Product classification
  • The total customs value of your purchase

For the vast majority of commercial imports, this “duty-free allowance” is not applicable.


Prohibited or Restricted Goods

Certain items that need to enter India are either “prohibited or restricted goods”.

This means such a product might:

  • Require a permit or licence to enter India
  • Be prohibited from entering the nation altogether
  • Be able to enter under a permit or specific requirements

International Shipping Customs Charges

“Customs duty and taxes” is part of, though not the only element, to calculate the complete international transportation costs of your shipment.

Other expenses will consist of:

  • Customs duties
  • Integrated GST
  • Any applicable surcharge
  • Transport service fees incurred at customs processing facility
  • Storage fees at the facility itself (if necessary)
  • Local transport costs in the nation you are sending them.
