What has to exist, who issues it, and the order in which it is normally produced for a consignment leaving India.
Documentation failure is the most common reason a ready consignment does not sail. None of it is difficult; it is simply unforgiving about sequence and consistency. Any mismatch between documents — a weight, a description, a value — will be found.
| Document | Issued by | Purpose |
|---|---|---|
| Proforma invoice | Exporter | The offer the buyer accepts; basis for the LC if there is one |
| Commercial invoice | Exporter | The transaction record; basis for value declared |
| Packing list | Exporter | Carton-level contents, weights and dimensions |
| Shipping bill | Exporter, filed with customs | The export declaration; without it nothing leaves |
| Bill of lading / airway bill | Carrier | Receipt, contract of carriage, and document of title |
| Certificate of origin | Chamber or authorised body | Determines preferential duty at destination |
| Insurance certificate | Insurer | Required under CIF and CIP terms |
| Inspection certificate | Third party | Where the buyer or destination regulator requires it |
| Phytosanitary / health certificate | Regulator | Agricultural, food and animal products |
Every document must agree with every other document. The description on the invoice, the packing list, the shipping bill and the bill of lading should be the same words. Gross weight should reconcile. The HS code should be identical everywhere it appears. Banks reject documents under a letter of credit for discrepancies that look trivial, because the whole instrument depends on documentary exactness.
Proforma invoice, Incoterm and payment method settled before anything moves.
Packing list finalised against actual cartons, not against the plan.
Customs declaration, with the classification you have verified.
Bill of lading issued once the goods are received or on board.
Full document set to the bank or direct to the buyer.
A complete document set that disagrees with itself is rejected faster than an incomplete one. Reconcile description, weight, value and HS code across every document before presenting.
Where classification is the open question, work back from cleared consignments in the Indian export record rather than guessing at the tariff schedule.
The core set is well known and rarely the problem. What delays consignments is the second tier: documents that are required only for certain goods, certain destinations or certain schemes, and which therefore do not appear on a generic checklist. A fumigation certificate for wooden packaging. A test report from a laboratory the destination recognises. A dangerous goods declaration for something nobody thought of as dangerous. A legalised invoice for a market that still requires consular attestation.
The way to find these is not to read a list but to ask the buyer and the destination customs broker what they need, in writing, before production starts. A broker at the destination knows exactly which documents get consignments held there, and that knowledge is both free and specific in a way that no general guidance can be.
| Conditional document | Triggered by | Found out too late when |
|---|---|---|
| Fumigation / ISPM 15 mark | Solid wood packaging | The consignment is held at destination |
| Laboratory test report | Food, cosmetics, electricals, toys | Production is complete and untested |
| Dangerous goods declaration | Chemicals, batteries, aerosols | The carrier refuses the booking |
| Consular / legalised invoice | Certain Middle East and African markets | Documents are already presented |
| Preferential origin certificate | Claiming an FTA rate | Duty is assessed at the full rate |
| Import permit held by buyer | Regulated products | Goods arrive and cannot be cleared |
Documentary discrepancy is the most common cause of delayed payment, and almost all of it comes from three fields that appear on multiple documents and are prepared by different people at different times: the goods description, the quantity and weight, and the value. The invoice is drawn by sales, the packing list by the warehouse, the shipping bill by the agent, the bill of lading by the carrier. Each is individually correct and collectively inconsistent.
The fix is procedural rather than clever. Prepare the goods description once, in the exact words the contract or letter of credit uses, and propagate it unchanged. Reconcile gross weight between the packing list and the carrier’s receipt before the bill is issued rather than after. Confirm the HS code is identical everywhere it appears. Ten minutes of reconciliation prevents a rejection cycle that costs weeks.
Customs administrations can audit years after clearance, and preferential origin claims can be verified long after the goods have been sold and consumed. What you need at that point is the contemporaneous file: the declaration, the invoice, the transport document, the origin evidence, the bill of materials that supported a value-addition calculation, and any correspondence about classification. Reconstructing that from memory is not possible, and the absence of it is treated as the absence of the claim.
A scanned, indexed document set costs almost nothing to maintain while a consignment is live and is close to impossible to assemble three years afterwards. This is the cheapest insurance in export operations.
Everything above is a framework, and a framework is only worth what it survives contact with. The useful discipline is to test each assumption against what consignments actually did, because customs data is one of the few commercial sources where the underlying event — goods crossing a border — physically happened and was documented under legal obligation at the time.
Fix the tariff line before anything else. Every filter, every duty figure and every comparison downstream depends on it.

Learn more ›Two failure modes account for most wrong conclusions drawn from trade data, and both are easy to avoid once named. The first is reading the incomplete tail of a series as a decline — authorities publish on a lag and revise afterwards, so the last one or two periods will fill in after you look. The second is reading a value movement as a demand movement, when declared value can move because volume moved, because unit price moved, or because the product mix inside a tariff line changed.
Customs data covers goods that crossed a border. It does not cover services, domestic trade, margin, contract terms or intent. Treat it as a dated, quantified observation to corroborate — not as a conclusion that arrives finished.
The difference between teams that get value out of trade data and teams that ran one interesting project is almost never analytical sophistication. It is whether the work became a routine. A saved query reviewed weekly, a short written note against each counterparty you assessed, and a standing habit of checking the period stamp before quoting a figure will out-perform an elaborate one-off study within a quarter, because markets move and a study does not.
The second habit worth building is writing down not just what you concluded but why and when. Records get revised, prices move, and counterparties change behaviour. Six months later nobody remembers whether a supplier was rejected on volume, on price band or on timing, and without that note the assessment simply gets repeated from scratch. A one-line rationale is what converts a list into institutional knowledge, and it costs seconds at the point where the thinking has already been done.
Finally, be explicit with colleagues about the confidence attached to any figure you circulate. A declared value from a complete period, controlled for origin and unit, is strong evidence. The same figure pulled from an incomplete recent period, averaged across a whole chapter, is barely evidence at all — and the two look identical once they are in a slide. Saying which one you have is what keeps trade data credible inside an organisation over time.
The certificate of origin, usually because nobody established early enough whether the buyer intended to claim a preferential rate. Without it the buyer pays full duty and the conversation about who absorbs that is unpleasant.
Usually yes, but a corrected presentation under a letter of credit may fall outside the presentation period, at which point compliance is lost even though the document is now right. Correct before presenting, not after.
The description, quantity, value and HS code should reconcile. Discrepancies invite queries, and queries cost time while detention and demurrage continue to accrue.
It is issued by an authorised chamber or designated body on the exporter's application. The exporter is responsible for the accuracy of what it certifies, including the origin claim itself.
Markets refresh on their customs authority's own release cycle — monthly for most, 45 to 60 days for a few. The most recent one or two periods are always still filling in, so exclude them when you are reading a trend rather than treating the gap as a decline.
Yes. Give us the HS code or a product description and the market you care about, and we will return a sample of live customs records filed against it.

The next questions this one usually raises are covered in The shipping bill, explained, Letters of credit, explained and Customs clearance in India, step by step. Each picks up where this article stops, and together they cover the sequence a consignment actually goes through — classification and duty before anything moves, documentation and payment while it moves, and verification of the counterparty before any of it is committed to. Reading them in that order is usually more useful than reading them by topic.
