IGM Filing and Amendment: Import Manifest Errors and Fixes

The customs broker files the bill of entry at 22:00, the vessel berths at Nhava Sheva next morning, and the entry sits unassessed for two days. Nobody misdeclared the goods. The shipping line's manifest shows the consignee as the importer's old trading name, the house bill number has a transposed digit, and the container is manifested for home clearance at the port when it was meant to move to an inland depot. Every day spent correcting it adds ground rent and line detention.

Those are manifest errors, and they are cheap to prevent and expensive to fix. Catching them before the vessel leaves its last foreign port keeps the correction inside the carrier's own amendment message; catching them after entry inwards sends the file to a customs officer, adds a written explanation and, at some custom houses, an amendment charge. A pre-filing match between the bill of lading, the manifest line and the draft bill of entry moves most corrections into the cheap window.

• What this guide covers: what India's import general manifest is after the Sea Cargo Manifest and Transhipment Regulations, 2018, its filing deadlines, the fields a bill of entry must match, and both amendment routes.
• What it adds: the US comparison under 19 CFR 4.7 and 4.12, penalty exposure on both sides, a worked cost of one error in dollars and rupees, a matching query, and a quality checklist.

What the import general manifest is after the SCMTR changeover

The import general manifest, or IGM, is the carrier's legal declaration of every consignment a vessel brings into an Indian port, and customs will not release cargo that is not on it. Section 30 of the Customs Act, 1962 requires the person in charge of a vessel or aircraft to deliver an arrival manifest or import manifest electronically before arrival; a vehicle at a land station delivers an import report within twelve hours of arrival.

The working format changed with the Sea Cargo Manifest and Transhipment Regulations, 2018 (SCMTR), notified as 38/2018-Customs (N.T.). Regulation 4 makes the arrival manifest a bundle: an application for entry inwards in Form II, a general declaration in Form III, stores and crew property lists in Forms IV and V, and the cargo declaration in Form VIA for a vessel arriving from a foreign port. Trade still calls the cargo part the IGM, and the bill of entry still quotes its number and date.

Under SCMTR the legacy IGM message has been replaced at gateway ports by electronic messages filed on ICEGATE. Jawaharlal Nehru Custom House Public Notice 78/2026 names them: the vessel operator files the Sea Arrival Manifest (SAM), and freight forwarders or consolidators file a Cargo Summary Notification (CSN) for their house bills, which the SAM must capture. The same notice disabled supplementary IGM filing at Nhava Sheva from 30 June 2026.

Filing deadlines: last port of call, update windows and US 24-hour rule

India fixes the manifest deadline to the vessel's last foreign port; the United States fixes it to loading at the origin port. SCMTR regulation 4(3) requires the general declaration and cargo declaration before the vessel departs its last port of call, with the rest of the arrival manifest due before arrival. Regulation 4(4), as the regulations stand after amendments including Notification 54/2019-Customs (N.T.), lets the carrier update cargo information later, inside fixed windows.

• Voyage over 96 hours: updates must be in before 48 hours of expected arrival at the destination customs port.
• Voyage of 48 to 96 hours: updates must be in before 24 hours of expected arrival.
• Voyage under 48 hours: updates must be in before 6 hours of expected arrival, which leaves almost no slack on short feeder legs from Colombo or Jebel Ali.
• Non-containerised cargo: the carrier may update irrespective of voyage duration, up to entry inwards at the destination port.

The US rule runs much earlier. Under 19 CFR 4.7(b)(2), CBP must receive the electronic cargo declaration 24 hours before the cargo is laden aboard the vessel at the foreign port, through AMS or another approved system. Bulk cargo is exempt from the pre-lading clock and is due 24 hours before arrival instead; break-bulk gets the same exemption only after a written request to CBP's National Targeting Center is granted.

India's sea arrival manifest must carry its cargo declaration before the vessel leaves the last foreign port under SCMTR regulation 4(3), with updates allowed until 48, 24 or 6 hours before arrival depending on voyage length; the US cargo declaration is due 24 hours before lading under 19 CFR 4.7(b)(2).

Neither clock is the importer's, yet the importer pays for misses. The bill of entry in India can be filed up to 30 days before arrival and must be in by the end of the day before arrival under Section 46(3); the carrier's manifest data has to be right before that filing can be assessed. Our guide to the ocean arrival notice sets out the late-presentation charge and the custodian's 30-day rule, so they are not repeated here.

Manifest fields that a bill of entry must match line for line

A bill of entry is matched to the manifest by number, date, line and sub-line, and any disagreement in the fields behind them stops the match. Form VIA in the SCMTR schedule lists 42 cargo fields per line plus container details. Most are carried over from the bill of lading, which is why a bill of lading drafted carelessly at origin becomes a customs problem at destination.

The consignee code field carries the most weight. The importer filing the bill of entry is identified by its importer-exporter code, and a manifest that names a different code, or none, prevents a clean link. Where the bill of lading is consigned "to order", the manifest must still carry notify-party details, and Form VIA asks for the notify party's PAN and address as separate fields.

Six common manifest errors and the document that proves each fix

Every correction needs a document that existed before the error was found, because customs permits an amendment only where it is satisfied there was no fraudulent intention. Section 30(3) of the Customs Act and SCMTR regulation 8 both put the test that way. The carrier's request should attach the evidence that shows the right value was always the intended one.

1. Transposed bill number: attach the original bill of lading and the carrier's booking confirmation showing the correct number.
2. Wrong consignee or code: attach the sales contract or commercial invoice naming the buyer, and the shipper's letter confirming the consignee.
3. Missing house bill: attach the house bill, the consolidator's loading list and the CSN acknowledgement or the reason it was not filed.
4. Package count difference: attach the packing list, stuffing tally and, where pallets were counted, a statement of cartons per pallet.
5. Wrong destination port or ICD: attach the booking showing the agreed place of delivery and the buyer's instruction to clear inland.
6. Weight difference: attach the weighbridge slip or verified gross mass declaration from origin; small bulk variances need no correction in the US under 19 CFR 4.12(b).

The pattern matters as much as the paper. A carrier that amends the same field on many vessels in a quarter invites the question of whether its origin process is adequate, and the US rule says so plainly: 19 CFR 4.12(a)(5) allows repeated similar discrepancies by the same parties to be treated as negligence rather than clerical error.

Amendment routes before and after entry inwards is granted

The grant of entry inwards to the vessel is the dividing line: before it, corrections are message-driven and quick; after it, they go to a proper officer. Public Notice 78/2026 at Jawaharlal Nehru Custom House sets out both routes for the SCMTR environment, and the same principle runs through regulation 8, which also lets the officer condone delay where there was sufficient cause.

• Before Sea Entry Inwards: additions or amendments to a bill of lading in the SAM or CSN go through the Sea Arrival Amendment or Sea Cargo Amendment message, as applicable, and are system-driven without routing through an officer.
• After Sea Entry Inwards: the carrier or consolidator applies to the proper officer, who may ask why the bill was not in the original SAM or CSN, and supplementary amendment charges may be levied under the existing procedure.
• After the bill of entry is filed: the entry itself may need amending under Section 149, which since 2021 also allows electronic amendment on risk-based criteria.
• After clearance: Section 149's proviso allows a bill of entry to be amended only on documentary evidence that existed when the goods were cleared.

Manifest amendments filed before Sea Entry Inwards travel as Sea Arrival Amendment or Sea Cargo Amendment messages on ICEGATE without officer routing, per JNCH Public Notice 78/2026; after entry inwards the proper officer decides under SCMTR regulation 8 and Customs Act Section 30(3), which typically adds one to three working days.

The "one to three working days" is our field observation, not a published standard, and it varies by custom house and season. What is fixed is the sequence: the manifest must be right before the bill of entry can be assessed, and a bill of entry amendment cannot cure a manifest that names the wrong consignee. Importers who use a consolidator should ask, in the service agreement, for the CSN acknowledgement before the vessel sails.

Transitional arrangements are still moving. Notification 61/2026-Customs (N.T.) of 1 July 2026 extended a transitional date in the table after Form XII to 31 August 2026, and JNCH Public Notice 80/2026 said no penal action would follow technical filing difficulties up to that date. Notification 90/2026-Customs (N.T.) of 1 November 2026 then moved that entry to 31 January 2027. The date has changed more than once, so check the entry in force before relying on any cut-off.

Penalties and liability: Sections 30, 116 and the US Form 5931 route

Late or wrong manifests expose the carrier to fixed penalty ceilings, while short-landed cargo exposes it to a duty-linked penalty that can be far larger. Section 30(1) allows a penalty of up to ₹50,000 where the manifest is delivered late without sufficient cause, and SCMTR regulation 13 sets the same ₹50,000 ceiling for any contravention of the regulations by an authorised carrier.

Section 116 is the expensive one. If goods loaded for import are not unloaded at their Indian destination, or the quantity unloaded is short, and the shortfall is not explained to the Assistant or Deputy Commissioner's satisfaction, the person in charge of the conveyance faces a penalty of up to twice the duty that would have been charged. A package count error on the manifest can therefore look like a short landing until the paperwork proves otherwise.

US manifest discrepancies are reported by the vessel master or agent on CBP Form 5931 within 60 days of the vessel's entry under 19 CFR 4.12, and penalties under 19 U.S.C. 1584 are avoided only when the error was a timely-reported clerical mistake with no loss of revenue.

Costing a manifest error in dollars and rupees

The penalty is rarely the largest cost of a manifest error; the days the container waits are. The worked example below prices one 40-foot container in each market whose manifest needed correction after the cheap window closed. All rates are illustrative and should be replaced with the carrier's tariff, the terminal or CFS schedule and the broker's quote for a real lane.

Carrying cost is the cargo value times the annual rate times days over 365: $62,000 × 0.18 × 2 ÷ 365 = $61, and ₹38,00,000 × 0.14 × 4 ÷ 365 = ₹5,830. Any customs supplementary amendment charge sits on top where the custom house levies one. At 40 such errors a year, the Indian figure exceeds ₹11 lakh, which pays for a pre-filing check many times over.

The calculation is also a negotiating tool. When the error sits with the consolidator, the service agreement should say who pays ground rent and detention caused by a late or wrong CSN. Without that clause the importer pays, because the CFS and the line invoice the party taking delivery. Our customs exam hold guide shows how a manifest discrepancy can also raise the odds of an examination.

A consignee mismatch that held a container for four days

The failure below is a composite of common cases, with invented document numbers. It shows how a small upstream error cascades once entry inwards has been granted and the bill of entry is already on file.

1. Day -6, 16:10, Jebel Ali: Consolidator issues house bill HBL-JEA-44817 to the buyer's former trade name; the importer's code field is left blank. CSN is filed the next day with the same data.
2. Day -1, 21:45, ICEGATE: Customs broker files an advance bill of entry quoting the master bill, house bill and the importer's code. The system cannot link it to sub-line 3 of line 112 because the consignee data differs.
3. Day 0, 07:20, Nhava Sheva: Vessel granted Sea Entry Inwards. The consolidator's Sea Cargo Amendment window has closed; the change now needs the proper officer.
4. Day 1, 11:30, custom house: Consolidator submits the amendment application with the sales contract and the shipper's consignee letter. The officer asks why the code was blank in the original CSN.
5. Day 4, 15:00, CFS: Amendment approved, bill of entry assessed and duty paid; out-of-charge follows and the container gates out with four days of ground rent and two days of detention on the importer's invoice.

The controlled version of the same shipment differs at one point. On Day -5, the importer's documentation desk compares the CSN extract the consolidator sends against the purchase order master and finds the blank code field. The consolidator files a Sea Cargo Amendment that afternoon, well before the update window closes, and the bill of entry links on arrival.

Checks the filing system enforces and calls a documentation lead makes

Field formats and links are machine checks; whether a correction is legitimate is a human call. Software can compare the bill of lading, the manifest extract and the draft bill of entry field by field in seconds, and it can read scanned bills to pre-fill a comparison. It cannot decide that an amendment is honest, and customs law reserves that judgement to the officer.

The comparison query below shows the core of a pre-filing check. It joins the draft bill of entry to the manifest extract the consolidator or line provides, and returns any line where an identifying field disagrees. Table and column names are an internal example, not an ICEGATE schema.

-- Flag draft bills of entry whose manifest link fields disagree
SELECT b.boe_draft_id,
       b.mbl_no, b.hbl_no,
       m.line_no, m.sub_line_no,
       CASE WHEN m.hbl_no IS NULL THEN 'HBL not on manifest'
            WHEN b.importer_code <> COALESCE(m.consignee_code, '') THEN 'Consignee code differs'
            WHEN b.package_count <> m.package_count THEN 'Package count differs'
            WHEN b.destination_code <> m.destination_port THEN 'Clearance location differs'
            ELSE 'OK' END AS check_result
FROM boe_draft b
LEFT JOIN manifest_extract m
       ON m.mbl_no = b.mbl_no
      AND m.hbl_no = b.hbl_no
WHERE b.vessel_eta >= CURRENT_DATE
ORDER BY b.vessel_eta, b.boe_draft_id;

Manifest quality checklist for carriers, consolidators and importers

Most manifest errors start at origin, so the checklist starts there and ends with the bill of entry. Use it as a service-level schedule with the line and the consolidator, and as an internal control for the importer's documentation desk. For the downstream reconciliation of bills of entry and shipping bills inside the ERP, see our ICEGATE bill of entry reconciliation guide, which covers ledger matching rather than manifest filing.

Measure two numbers each month: the share of bills of entry that linked to the manifest at first attempt, and the number of amendments filed after entry inwards. The first should sit above 98 percent on mature lanes; the second should trend towards zero. Both are internal targets we suggest, not regulatory thresholds. More import-document guides sit in our logistics and supply chain library.
