What changed on 1 July 2026
India introduced the Sea Cargo Manifest and Transhipment Regulations, 2018, usually shortened to SCMTR, to replace fragmented cargo-reporting processes with a standard electronic framework. The system covers vessel arrivals and departures, import and export cargo, transhipment moves and the parties responsible for filing each message.
The planned date for complete rollout was 30 June 2026. CBIC then issued Circular No. 29/2026-Customs and Notification No. 61/2026-Customs (N.T.) on 1 July, extending the transitional provisions to 31 August 2026. The reason was practical: trade bodies had reported technical and procedural problems during the nationwide rollout.
The extension is a correction window, not a delayed launch
CBIC says all prescribed SCMTR electronic messages except Import Transhipment messages were operational from 1 July 2026. Stakeholders are expected to file them now. The extension protects the trade from penal action for technical or procedural difficulties until 31 August; it does not pause the filing requirement or excuse knowingly incomplete cargo data.
Who needs to be ready
The circular is aimed directly at the organisations that create, carry, receive or control sea-cargo information. It names Authorised Sea Carriers, including shipping lines; Authorised Sea Agents, such as steamer and shipping agents; Authorised Carriers, including transhippers; terminal operators; and custodians.
Forwarders, NVOCCs, consolidators and cargo owners are also part of the data chain even when they do not file every customs message themselves. A shipping line cannot create a correct master filing when the House Bill, Shipping Bill, shipping instructions or shipper details arrive late or disagree. Operational responsibility may sit with the filer, but bad source data still comes back to the party that supplied it.
- Shipping lines and agents should confirm their SCMTR role, ICEGATE access, authorised users and message connectivity.
- NVOCCs and consolidators need approved registration and a reliable process for House Bill and Cargo Summary Notification data.
- Freight forwarders must collect complete shipper, consignee, cargo and vessel details early enough for the carrier cutoff.
- Importers and exporters should make sure commercial documents, Shipping Bills and transport documents use the same product and party data.
- Terminal operators and custodians need to file the movement and custody messages assigned to their role.
The identifiers you will keep seeing
SCMTR introduces several identifiers and message names that can make a simple shipment sound more complicated than it is. The important part is understanding where each reference enters the chain:
- VCN, or Voyage Call Number, identifies a vessel call at an Indian port and ties cargo messages to the correct voyage.
- CSN, or Cargo Summary Notification, carries House Bill-level cargo details from a consolidator or forwarder into the customs chain.
- PCIN, or Primary Cargo Identification Number, is the unique cargo reference generated against a Bill of Lading filing.
- MCIN, or Master Cargo Identification Number, links consolidated cargo under the relevant master transport document.
- SAM and SOM are the Sea Arrival Manifest and Sea Departure Manifest filed for incoming and outgoing vessel cargo.
You do not need every acronym on every shipment. Your role determines which messages you create. But you do need the references passed back to you, especially when a House Bill must be linked to the carrier's master filing or an amendment is required.
Why the 72-hour window matters
Customs law sets the framework, while carriers publish operational cutoffs that allow them to assemble and validate the filing. CMA CGM India's May 2026 advisory, for example, asks forwarders and consolidators to provide the CSN number, CSN date and PCIN at least 72 hours before vessel arrival. It also requires the House Bill to be uploaded within that window with the CMA CGM master Bill number clearly shown.
The same advisory requests final shipping instructions at least 48 hours before arrival for cargo loading from a gateway port and five days before arrival for an ICD shipment. Those are CMA CGM operational cutoffs, not a universal timetable for every carrier. Your carrier may set an earlier deadline, particularly for weekends, transhipment cargo or voyages with short transit times.
Work from the carrier cutoff, not the customs deadline
The filing party needs time to validate your data and resolve ICEGATE rejections. If the carrier asks for House Bill information 72 hours before arrival, sending it at hour 71 leaves no useful correction window. Build an internal cutoff earlier than the carrier's published one.
The data must match across every document
SCMTR makes inconsistencies easier for Customs to detect because data that once sat in separate documents now enters a connected electronic record. CMA CGM's advisory requires the following information to remain consistent across shipping instructions, the Shipping Bill, House Bill and Master Bill:
- 6-to-8-digit HSN code describing the goods at the required level of detail.
- Package count and package type using the same units and totals.
- Gross weight without unexplained differences between commercial and transport documents.
- IEC and PAN of the actual shipper, not a convenience-party substituted at the last minute.
- Complete address, state, country code and PIN code for the declared parties.
- Shipping Bill number and date, correctly linked to the Bill of Lading and PCIN.
The HSN code deserves attention before the rest of the filing is assembled. A vague description such as 'parts', 'chemicals' or 'general merchandise' is not a substitute for classification. The code affects the manifest description, customs assessment, restrictions and the consistency checks between your Shipping Bill and transport documents.
One Shipping Bill, one Bill of Lading
The carrier guidance also calls out a structural rule that can catch documentation teams: one Shipping Bill should link to one Bill of Lading. Multiple master Bills against the same Shipping Bill are not accepted in that workflow. If your commercial arrangement normally splits one export declaration across transport documents, confirm the correct structure with your customs broker and carrier before final documents are issued.
For consolidated cargo, the House Bill and master Bill relationship must also be explicit. Console agents need the correct SCMTR registration to file House Bill-level manifestations, and the carrier needs the resulting cargo references in time to complete its master filing.
What the no-penalty period really covers
CBIC says no penal action will be initiated up to 31 August 2026 for technical or procedural difficulties encountered in the online SCMTR filing mechanism. That wording matters. It gives stakeholders room to identify system errors, work with Customs field formations and correct implementation problems while the framework settles in.
It should not be read as blanket immunity for false declarations, missing commercial records or deliberate non-compliance. Keep evidence of rejected messages, helpdesk tickets, corrected filings and communications with the carrier or Customs. If a genuine system problem prevents filing, the audit trail shows that you attempted to comply and acted on the error.
A practical SCMTR readiness checklist
- Confirm registration now. Check that the entity, role, authorised parent user and required child users are approved in ICEGATE.
- Test the real workflow. Do not stop at successful registration. File the messages your role requires and record every validation error.
- Map ownership. Write down who supplies, checks, files and amends each piece of cargo data across the exporter, forwarder, NVOCC, broker and carrier.
- Move internal cutoffs earlier. Give your team time to correct HSN codes, party details, weights and document links before the carrier deadline.
- Create one source record. Use the same approved shipment data to prepare the SI, Shipping Bill, HBL, MBL and CSN submission.
- Track cargo references. Store VCN, CSN, PCIN and master references with the shipment so amendments do not depend on an email search.
- Escalate system issues before 31 August. Use ICEGATE support and the weekly outreach sessions directed by CBIC while the transitional protection remains available.
The bottom line
India's SCMTR transition ends on 31 August 2026, but the filing system is already operating. Treat this month as a controlled final test, not extra time to postpone registration. Confirm who owns each filing, align the HSN code and party data across every document, work ahead of the carrier cutoff and keep evidence of technical failures. The companies that struggle after the deadline will not be the ones that missed an acronym. They will be the ones whose teams, documents and systems still disagree about the same cargo.
