Modus Operandi of Customs Duty Evasion in India: A Practical Guide for Import Investigations

 The modus operandi can be organized according to the stage at which the fraud occurs: classification, valuation, quantity, origin, exemption, documentation, and physical movement of goods.

Major Modus Operandi of Customs Duty Evasion in Imports

No.	Modus operandi	Typical mechanism	What Customs may verify
1	Undervaluation	Importer declares a value lower than the actual price paid/payable	Commercial invoice, payment trail, purchase order, contracts, related-party transactions, contemporaneous import values
2	Misclassification	Goods are declared under an incorrect HS/CTH attracting lower duty	Technical literature, product catalogue, specifications, composition, end-use and tariff headings
3	Misdeclaration of description	Actual goods are described as another product or with incomplete specifications	Physical examination, catalogue, packing list, laboratory/technical examination
4	Quantity suppression	Actual quantity imported is higher than the quantity declared	Invoice, packing list, weight, examination report, transport documents and inventory records
5	Incorrect country of origin	Origin is declared incorrectly to obtain preferential/concessional treatment or avoid applicable measures	Certificate of Origin, manufacturing records, supplier information and origin criteria
6	Fraudulent exemption/concession claim	Importer claims a notification/concession without satisfying its conditions	Notification conditions, declarations, certificates, end-use records and eligibility documents
7	Wrong end-use declaration	Goods are imported under a concessional rate based on a specified end-use but are diverted or conditions are not fulfilled	End-use certificates, consumption records, production records and subsequent disposal
8	Related-party valuation manipulation	Relationship between buyer and seller is not properly disclosed or the declared price is influenced by the relationship	Ownership/control information, transfer-pricing documents, agreements and financial records
9	Suppression of assists	Certain buyer-provided materials, designs, engineering, tools or similar elements relevant to valuation are not appropriately reflected	Contracts, technical agreements, royalty/licence arrangements and cost records
10	Royalty/licence fee suppression	Dutiable additions connected with imported goods are omitted from valuation	Licence agreements, royalty calculations and payment records
11	Freight/insurance manipulation	Relevant transportation or insurance components are incorrectly declared or omitted where legally includible	Freight invoices, insurance documents, bills of lading/airway bills
12	Multiple invoicing	Different versions of commercial invoices are used for Customs and commercial/payment purposes	Supplier records, bank remittances, accounting books, emails and purchase orders
13	Over/under-invoicing with parallel payment arrangements	Declared invoice does not represent the actual commercial consideration	Banking channels, overseas remittances, ledger accounts and correspondence
14	Fictitious or accommodation suppliers	Documentation is created through entities that do not reflect the actual supply chain	Supplier KYC, shipping records, payment trail and overseas business information
15	Split consignments	A transaction/consignment is divided into multiple shipments to exploit procedural or exemption thresholds	Purchase orders, shipment history, supplier correspondence and common importer/supplier patterns
16	Misuse of courier/postal channels	Commercial imports may be incorrectly represented or described to obtain an inappropriate treatment	Nature of goods, transaction value, consignee/importer profile and supporting documents
17	Smuggling / non-declaration	Goods are brought into India without proper presentation/declaration to Customs	Manifest, surveillance, examination, intelligence and movement records
18	Concealment within declared cargo	Undeclared goods are concealed within containers/packages containing declared goods	Risk-based examination, scanning, physical examination and packing pattern
19	Prohibited/restricted goods declared as ordinary goods	Restricted or prohibited goods are described as permissible commodities	Physical examination, licences, NOCs, regulatory requirements and technical characteristics
20	Misuse of FTA/preferential origin benefits	Preferential duty is claimed without satisfying applicable origin requirements

CBIC specifically recognizes misdeclaration of nature, value and quantity, as well as attempts to bypass Customs through unauthorized routes, as forms of customs fraud/smuggling.

1. Valuation-related evasion

This is one of the most important areas for investigation.

Under Section 14 of the Customs Act, 1962, the transaction value is generally the price actually paid or payable, subject to the statutory conditions and additions prescribed under the valuation framework. The law also provides for examination of declared value where Customs has reason to doubt its truth or accuracy.

A useful investigation sequence is:

Declared value → supplier invoice → purchase order → contract → bank payment → books of account → overseas supplier records → related-party relationship → valuation additions

2. Classification-based evasion

An importer may attempt to obtain a lower duty rate by declaring goods under a different tariff heading.

For example, an investigation may compare:

Declared CTH → actual product specification → composition → technical literature → intended use → applicable tariff heading → applicable duty

The important point is that classification should be established from the legal tariff provisions and the actual characteristics of the goods, rather than simply from the description appearing on the invoice.

3. Quantity and description manipulation

A common risk pattern is:

Invoice says 1,000 units → packing list says 1,000 → examination finds 1,250 units

or:

Invoice describes a general product → examination reveals a higher-duty/specially regulated product.

CBIC materials specifically identify suppression of quantities and misdeclaration of the nature and value of goods as fraudulent practices.

4. Exemption and concessional-duty misuse

Another important area is claiming a notification benefit while failing to satisfy one or more conditions.

Investigation should examine:

• Eligibility of importer
• Description of goods
• Required certificates
• End-use condition
• Quantity/value conditions
• Time limits
• Installation/consumption requirements
• Subsequent disposal/diversion
• Maintenance of prescribed records

CBIC notifications frequently make concessional treatment conditional on specified certificates, restricted-import authorisations, export obligations or compliance with the IGCR Rules, 2022.

5. Country-of-origin manipulation

This can become particularly important where duty treatment depends on origin.

Potential indicators include:

• Unusual routing through an intermediary country
• Supplier and manufacturer being different entities
• Certificate of Origin inconsistent with commercial documents
• Goods bearing indications of another manufacturing country
• Unusual price differences between suppliers
• Lack of evidence of substantial processing in the claimed originating country

6. Undeclared commercial consideration

An important investigation angle is whether:

Declared invoice value = actual commercial consideration

The investigation may therefore connect:

Import documents + bank transactions + accounting records + purchase orders + emails/contracts + supplier records

rather than relying only on the Bill of Entry.

7. Smuggling and concealment

At the more serious end, the modus operandi can involve:

Non-declaration → concealment → unauthorized route → false description → removal without Customs clearance

CBIC notes that Customs law provides powers and penalties relating to smuggling and serious commercial fraud, including seizure/confiscation and penalties, subject to the applicable statutory provisions.

For improper importation, Section 112 of the Customs Act provides penalties in specified circumstances involving goods liable to confiscation under Section 111.

Practical Anti-Evasion Risk Matrix

For Customs investigation training, I would group the entire subject into these 10 major heads:

1. Undervaluation
2. Misclassification
3. Misdescription
4. Quantity suppression
5. Country-of-origin fraud
6. Wrong exemption/concession
7. End-use condition violation
8. Suppression of valuation additions
9. Documentary/commercial fraud
10. Smuggling, concealment and non-declaration
