Can customs demand more duty after my goods were cleared, and how long do I have to claim back duty I overpaid?

Clearance does not close the file. The Customs Act, 1969 gives customs a fixed window to come back for duty that was missed, and gives you a much shorter window to recover duty you paid by mistake. Both windows are counted from dates the Act defines.

What does the law say about demands after clearance?

Section 32 has three time limits, each for a different cause of the short levy.

Sub-section	Cause of the short levy	Notice must be served within
32(2)	A false document or statement, or collusion	Five years of the relevant date
32(3)	Inadvertence, error or misconstruction	Three years of the relevant date
32(3A)	Found by audit or examination of the importer’s or exporter’s accounts, or by any means other than the documents provided at import or export	Five years of the relevant date

Each notice asks the person to show cause why the amount should not be paid. Under section 32(4), the officer considers any representation and determines the amount payable, which “shall in no case exceed the amount specified in the notice”.

Small amounts. The first proviso to section 32(3) says no action is initiated where the recoverable amount is under twenty thousand rupees. The second proviso says no action is initiated where the full short-paid amount is paid voluntarily before an audit, inquiry or investigation begins. The proviso to section 32(3A) says that where the recoverable amount is under one hundred thousand rupees, no action is initiated if the person deposits the recoverable amount.

Audits. Section 26A(1) says a customs audit proceeds in the manner the Board prescribes by rules, and section 26A(2) allows the officer to examine records and summon the importer, exporter, their employees or agents to produce records and give testimony. A short levy found this way falls under the five-year limit in section 32(3A).

When does the clock start?

Section 32(5) defines “relevant date”:

• (a) where duty was not levied, the date the clearance order is made;
• (b) where duty was provisionally assessed under section 81, the date of adjustment after final assessment;
• (c) where duty was wrongly refunded, the date of refund;
• (d) in any other case, the date of payment of duty or charge;
• (e) for clearance through the Customs Computerized System on self-assessment or electronic assessment, “the date of detection”.

Clause (e) matters for most modern clearances. Where it applies, the three- or five-year period runs from when the short levy is detected, not from when the goods left customs. Section 32 does not set a separate outer limit on when detection can happen.

How long do I have to claim a refund?

Section 33(1) says no refund of duty paid or overpaid “through inadvertence, error or misconstruction” is allowed unless the claim is made within one year of the date of payment. The start date moves in two cases:

• Section 33(2): for provisional payments under section 81, the year runs from the adjustment after final assessment.
• Section 33(3): where the refund is due because of a decision of a customs officer, the Board, the Appellate Tribunal or a court, the year runs from that decision.

Section 33(3A) requires the claim to be disposed of, subject to pre-audit, within 120 days of filing, which the Collector may extend by up to 90 days for recorded reasons. Section 33(4) bars any refund where the duty has been passed on to the buyer or consumer.

Worked example (illustrative figures)

Ayesha runs a Faisalabad textile unit. She paid duty on a consignment of dyes on 10 August 2025, and the goods were assessed on the documents she filed.

1. An honest error that customs finds from her documents. Relevant date under section 32(5)(d) is 10 August 2025. Three years later is 10 August 2028, the last date for a section 32(3) notice.
2. Found in a later audit of her accounts. Section 32(3A) applies: five years, to 10 August 2030.
3. Cleared on self-assessment through the Customs Computerized System. Under section 32(5)(e) the relevant date is the date of detection. If detected on 1 March 2027, the three-year limit runs to 1 March 2030.
4. Short levy of Rs. 15,000 from an honest error. This is under twenty thousand rupees, so the first proviso to section 32(3) bars action.

Separately, she finds she overpaid Rs. 180,000 on a shipment paid for on 15 January 2026. Under section 33(1), her claim must be made by 15 January 2027. If filed on 1 December 2026, section 33(3A) requires disposal within 120 days, which is 31 March 2027 (30 days in December, 31 in January, 28 in February, 31 in March), unless the Collector extends it.

What if I disagree with the demand or the refund decision?

Section 193(1) allows an appeal to the Collector (Appeals) against refund orders under section 33 and adjudication orders on short-levy notices, among others, passed by an officer below the rank of Additional Collector, within thirty days of the order being communicated. Section 193(3) sets a fee of one thousand rupees.

Common mistakes

• Assuming three years always applies. It applies only to inadvertence, error or misconstruction. False statements, collusion and audit findings get five years.
• Counting from the clearance date on a self-assessed entry. Section 32(5)(e) uses the date of detection.
• Leaving a refund claim late. Section 33 gives one year, and a refund can still be refused under section 33(4) if the duty was passed on.

What to check in the official text

Read section 32(2), (3), (3A), (4) and (5), section 33 in full, and section 26A. The Board’s audit rules under section 26A(1) and any notification under section 33(5) on refund powers are not reviewed on this page.
