Customs clearance feels like a black box to most importers — cargo goes in, days pass, invoices appear. Here is what actually happens between vessel arrival and delivery, and where the time really goes.
1. Import General Manifest (IGM)
Before arrival, the carrier files the IGM with customs listing every consignment on board. Your shipment legally exists for customs only once it's on a filed IGM — errors here (wrong consignee, wrong description) must be amended before anything else proceeds.
2. Bill of Entry (BoE) Filing
The importer's customs broker files the Bill of Entry on ICEGATE under Section 46 — ideally before arrival (prior BoE), which starts assessment early and cuts dwell time. The BoE declares classification (HS code), valuation, duty calculation, and any licences or compliance certificates.
3. Assessment
Most BoEs are self-assessed and system-cleared through Risk Management System (RMS). A percentage is routed for officer assessment — where classification, valuation or notification claims are scrutinised. Weak documentation here triggers queries; each query cycle can add days.
4. Examination
RMS also decides whether goods are physically examined. "First Check" (examine before assessment) applies in specific cases; most examined cargo goes through "Second Check" after duty payment. Regulated products may additionally face FSSAI sampling, drug/cosmetic checks or other agency verification at this stage.
5. Duty Payment
Duty is paid electronically via ICEGATE. The calculation stack: Basic Customs Duty on assessable value → Social Welfare Surcharge on BCD → IGST on the cumulative value. FTA claims (with valid Certificates of Origin) and exemption notifications apply here — this is where classification quality turns into money.
6. Out of Charge (OOC) & Delivery
Once duty is paid and any examination closed, customs grants Out of Charge. The custodian (port/CFS/airport) releases cargo against OOC and its own charges, and goods move to your warehouse.
Where Delays Actually Come From
- Late or missing documents from the supplier — the #1 cause, entirely preventable
- Wrong HS classification triggering assessment queries
- Missing compliance licences (BIS, CDSCO, FSSAI) — cargo cannot clear without them
- IGM errors requiring amendment
- Duty payment delays on the importer's side
Routine, well-documented consignments clear JNPT in 2–5 working days. Everything slower has a specific, usually preventable cause.
