The Documentation Toolkit
Nobody is ever handed a list of the papers their shipment needs. They find out one document at a time, usually from somebody who is annoyed with them, and usually too late to do anything cheaply about it.
So here is the list. Pick the kind of shipment you are doing and you get a folder: every document, who gives it to you, when you need it, and what happens if it is missing. Written for someone who has never done this before.
The one thing to understand before you read any folder
Documents fall into three groups, and the group matters far more than the name. Every document below is tagged with which one it belongs to.
The rule Anything marked before shipment or issued at origin becomes impossible, or very expensive, once the goods have left. Those are the ones that ruin shipments. The port documents are mostly just work.
Tap a folder title to open it.
Bringing goods in by sea, a full container
Who this is for: A business importing a container of goods
The most common import there is, and the one with the most paperwork. Almost everything that goes wrong here was decided weeks before the ship arrived.
- Proforma invoiceBefore shipment The supplier's formal written offer: what the goods are, how many, the price and the terms. Your bank needs it before anything else can start.
- Form MBefore shipment The government form that registers your import and books the foreign currency to pay your supplier. Your bank opens it. It must be registered BEFORE you place the order, and it expires (180 days, or 365 for plant and machinery).
- Insurance certificateBefore shipment Cover for the journey, from a local insurer. Arrange it before the goods move, because cover bought after a loss is worth nothing.
- Product certificate from the standards bodyBefore shipment For regulated goods. Inspected and issued in the supplier's country before loading, and it cannot be obtained afterwards at any price.
- Commercial invoiceIssued at origin The final bill from the supplier. Every figure must match the Form M.
- Packing listIssued at origin What is inside, box by box, with weights. Customs reads it during examination.
- Bill of ladingIssued at origin The shipping line's transport document. It is the receipt for your cargo and the document that proves who owns it.
- Certificate of originIssued at origin Says where the goods were actually made. It decides whether a trade agreement can reduce your duty.
- Combined certificate of value and originIssued at origin A single sworn form combining the value and the origin, required by many customs authorities.
- Pre-arrival assessment reportAt the port Customs telling you, before the ship lands, which code they accept and what you will pay. The moment your estimate becomes a real number.
- Customs declarationAt the port The formal entry your licensed agent files, using every document above.
- Assessment notice and duty receiptAt the port The final bill and the proof you paid it at the bank.
- Delivery orderAt the port The shipping line releasing the container to you, once their charges are settled.
- Gate passAt the port The terminal letting the truck out, once storage and handling are paid.
What blocks it No Form M, or a Form M that has expired. A missing standards certificate. Any mismatch between the bill of lading, the invoice and the packing list.
How long to allow: Allow 2 to 4 weeks for the paperwork before the goods sail, then whatever the voyage takes, then 5 to 10 working days at the port if nothing is queried.
Bringing goods in by air
Who this is for: Anyone importing something urgent, valuable or light
Faster, more expensive, and less forgiving. The cargo often lands before the paperwork does, and every day it waits at the airport costs money.
- Proforma invoiceBefore shipment The supplier's offer. Still needed, even for a small urgent shipment.
- Form MBefore shipment Required above the value threshold your country sets. Below it, a simpler route may apply. Ask your bank before you assume.
- Regulatory permitBefore shipment Medicines, food, cosmetics, telecoms equipment and chemicals each need their own agency approval, obtained before shipping.
- Commercial invoice and packing listIssued at origin The final bill and the contents list. Air shipments are often queried on value, so make these precise.
- Air waybillIssued at origin The airline's transport document. Unlike a bill of lading it is NOT a document of title, so it does not prove ownership.
- Dangerous goods declarationIssued at origin For anything flammable, pressurised, magnetic, corrosive or containing a battery. Getting this wrong grounds the shipment.
- Pre-arrival assessment reportAt the port As for sea. Apply early, because air cargo arrives in days.
- Customs declaration, assessment and duty receiptAt the port The entry, the bill and the proof of payment.
- Handling company releaseAt the port The ground handler releasing the cargo once their storage and handling charges are paid.
What blocks it Storage at an airport is charged per kilo per day and starts almost immediately. A permit that was not obtained before shipping is the usual cause of a long, expensive wait.
How long to allow: The flight takes a day. The paperwork does not. Start the permits and the Form M at least two weeks before the supplier ships.
A small shipment in a shared container or by courier
Who this is for: Small traders, online sellers, anyone importing part of a container
Your goods travel with other people's. That makes it cheaper and it makes you dependent on strangers, because one problem consignment in the container can hold up everybody's.
- Commercial invoice and packing listIssued at origin Yours specifically, clearly marked, so your goods can be separated from everyone else's.
- House bill of lading or house air waybillIssued at origin Issued by the consolidator for your portion, not by the carrier. It only works with the consolidator who issued it.
- Cargo arrival noticeAt the port Tells you the shipment has landed and what you owe. Watch for it, because free time starts whether you read it or not.
- Simplified declarationAt the port Many countries allow a lighter entry below a value threshold. Ask whether yours qualifies before paying for a full one.
- Duty receipt and releaseAt the port Payment and the release note from the consolidator's warehouse.
What blocks it Waiting for the whole container to be cleared. Your goods cannot move until the consolidation is broken down, and that depends on every other consignment in it.
How long to allow: Add one to two weeks to a normal sea transit for consolidation at both ends.
Moving house, or personal effects
Who this is for: Someone relocating, or returning home after living abroad
Treated completely differently from commercial cargo, and often with a concession that removes most of the duty. The concession has conditions, and they are checked.
- Passport and residence evidenceBefore shipment Proof of who you are and that you genuinely lived abroad for the qualifying period.
- Detailed inventory, valuedBefore shipment Every item, listed and given a realistic value. Vague lists invite examination and delay.
- Bill of lading or air waybillIssued at origin The transport document, in your own name.
- Declaration that the goods are used and personalIssued at origin Signed by you. New goods in the box turn the shipment into a commercial import.
- Application for the returning resident concessionAt the port Where you qualify, this is what removes or reduces the duty. It must be applied for, never assumed.
What blocks it New items mixed in with used ones. A vehicle included without declaring it separately. Falling short of the time-abroad requirement.
How long to allow: Apply for the concession before the goods arrive. Deciding at the port is how a household ends up paying full commercial duty.
Goods going into or coming out of a free zone
Who this is for: Manufacturers, traders and anyone buying from a company inside a free zone
A free zone is treated as outside the country for customs purposes, even though it is physically inside it. So moving goods OUT of a zone into the local market is a full import, with full duty, even though nothing crossed a border.
- Zone authority approvalBefore shipment The free zone regulator's permission for the movement. Nothing moves without it.
- Form MBefore shipment Yes, even though the goods are already in the country. The exit into the local market is an import.
- Zone exit or entry permitAt the port Issued by the zone authority, naming the goods and the destination.
- Invoice from the zone enterpriseAt the port The seller inside the zone bills you as a foreign supplier would.
- Customs declaration under the correct procedure codeAt the port A free zone exit uses its own code. Filing it as an ordinary import causes a rejection.
- Duty receipt and zone gate passAt the port Payment, then the zone letting the goods leave.
What blocks it Assuming that because the goods are already in the country there is no duty. There usually is, at the full rate.
How long to allow: Allow the same time as a normal import. The distance is short and the paperwork is not.
Claiming a duty exemption or a waiver
Who this is for: Projects, institutions, NGOs and anyone entitled to relief
Real reliefs exist, they are written into law, and they are approved in advance. An approval you do not hold before clearance is not a relief, it is a hope.
- Application to the finance ministryBefore shipment The formal request for the exemption certificate, naming the project and the goods.
- Letter of support from the supervising ministryBefore shipment The ministry responsible for your sector confirming the project is what you say it is.
- Company registration and tax clearanceBefore shipment Proof the applicant is a real, compliant entity.
- Proforma invoice and Form MBefore shipment The shipment the exemption applies to. An exemption is granted for specific goods, not in general.
- Exemption certificateBefore shipment The approval itself, which the customs system must be able to see before the entry is filed.
What blocks it Shipping first and applying afterwards. Almost every relief must be in place before clearance, and the goods sit accruing charges while the application is processed.
How long to allow: Weeks, sometimes months. Start before the supplier is even paid.
Sending goods out by sea
Who this is for: Exporters of produce, minerals, manufactured goods
Exporting has fewer charges than importing and more conditions. The paperwork exists mainly so the country can track the goods and the money coming back.
- Export registrationBefore shipment Your business must be registered as an exporter before it can export anything.
- Export form from your bankBefore shipment The mirror of the Form M: it registers the export and tracks the money returning.
- Quality or fumigation certificateBefore shipment For agricultural produce, minerals and food. The buyer's country usually specifies which one.
- Phytosanitary certificateIssued at origin For plants and produce, issued by the agricultural quarantine authority after inspection.
- Commercial invoice and packing listIssued at origin For the buyer and for both customs authorities.
- Certificate of originIssued at origin What lets your buyer claim a lower duty under a trade agreement. It can be worth more to them than a price cut.
- Bill of ladingAt the port The transport document, and often what the buyer's bank pays against.
- Export customs entryAt the port The declaration on the way out.
What blocks it A missing phytosanitary certificate on produce. An export form opened after the goods have already moved.
How long to allow: Two to three weeks of preparation for a first-time exporter, less once you are registered and known.
Importing a vehicle
Who this is for: Individuals and dealers bringing in a car, van, truck or motorcycle
Vehicles have their own rules, their own duty rates, and an age limit in many countries. The commonest painful surprise is a vehicle that cannot legally be imported at all.
- Age and eligibility checkBefore shipment Before you buy. Many countries refuse vehicles above a certain age outright, and the rule changes.
- Form MBefore shipment As for any import above the threshold.
- Title or ownership documentIssued at origin From the country of export, showing the vehicle is legally yours and not stolen or written off.
- Bill of ladingIssued at origin Naming the vehicle by its chassis number.
- Customs declaration with the chassis numberAt the port Vehicles are assessed individually, and the value is checked against published guides rather than only your invoice.
- Duty receipt and customs release papersAt the port Needed later to register the vehicle locally, so keep them safe.
What blocks it Buying first and checking the age limit afterwards. A value on the invoice far below what the vehicle is worth.
How long to allow: Check eligibility on the day you see the vehicle, not the day you pay for it.
Ten rules that apply to every folder
Almost every expensive delay traces back to a document that could have been obtained weeks earlier, cheaply, while nothing was waiting.
Once the goods have left, they cannot be created at any price. This is the single most costly thing people learn late.
The name, the address, the description, the quantity, the weight, the value and the currency. One mismatch is a query, and a query is days.
At sea, whoever holds the original bill of lading controls the cargo. By air, it does not work that way. Know which you have.
If a quotation does not say whether duty is included, the person paying will assume it is.
Registration forms, certificates and quotations all have dates. An expired document is the same as no document.
An exemption you have applied for is not an exemption you hold.
Ask early which documents must be presented in original, and how they will physically reach the port.
Not when you are told, and not when the paperwork is ready. Storage and demurrage do not wait for you.
Customs authorities can audit an entry long after the goods are sold. The file is your defence.
