Import documents checklist: every paper from proforma to proof of delivery, in order
Import documents checklist: every paper from proforma to proof of delivery, who issues it, when you touch it, and what breaks if it's wrong.
InventoryX is in development and not available today. ClearStock is the live Shopify app.
A single ocean shipment passes through a dozen documents issued by four different parties, and you personally touch most of them exactly once — which is why nobody learns them until one is wrong. The failure mode is almost never "we couldn't get a document." It's sequence: the ISF filed after loading, the commercial invoice that never matched the PO, the delivery order nobody chased while container free-time ran out.
This is the timeline in order — who issues each document, when it lands on your desk, and what breaks when it's wrong — built for someone importing, say, 600 phone stands from a factory in Ningbo. Per-document detail lives in the linked guides; this page owns the sequence.
The document timeline at a glance
| Document | Who issues it | When you touch it | What breaks if it's wrong |
|---|---|---|---|
| Proforma invoice | Supplier | Quote stage — before you commit; basis for budget and deposit | You wire a deposit against wrong totals or terms; errors ripple into every later document |
| Purchase order | You | PO stage | Not a customs document, but every downstream document should trace back to it; a vague PO produces vague paperwork |
| Spec confirmation / approved sample reference | You + supplier | Production start | No document fixes goods made to the wrong spec |
| Inspection report (if used) | Third-party QC firm | Pre-shipment, at 80%+ production | Defects discovered after shipping instead of before |
| ISF filing | You or your agent (forwarder/broker), data mostly from supplier | Before loading — 24 hours before laden aboard, ocean cargo | Cargo refused loading or held; penalties up to $5,000 per violation |
| Shipper's letter of instruction (if used) | You, to your forwarder | Booking | Forwarder books wrong terms, dates, or routing |
| Bill of lading | Carrier (often via the forwarder) | Issued at loading | Wrong consignee or description blocks cargo release at destination |
| Commercial invoice | Supplier (exporter) | At shipment; used at entry | Customs valuation is wrong → wrong duties, exam triggers |
| Packing list | Supplier | Travels with the shipment; used at entry and receiving | Carton-level mismatch slows exams and your own receiving count |
| Certificate of origin (where applicable) | Supplier / chamber of commerce | With the entry, where preference or requirements apply | Lost preferential duty treatment; entry holds |
| Customs bond | You — or your broker's continuous bond | Before entry, for formal entries | Entry can't be filed |
| Arrival notice | Carrier or forwarder | At destination arrival | You miss free-time windows and storage charges start |
| Entry filing + duties/fees | Your customs broker | At arrival | Goods don't move; late-filing penalties accrue |
| Delivery order | Carrier or forwarder | Before truck pickup | The trucker can't collect the container |
| Proof of delivery (POD) | Carrier/trucker, signed by you | At delivery | You've lost your receipt evidence for shortage or damage claims |
Fifteen rows, but only about six require real judgment from you. The rest are confirmations.
Stage by stage, with the judgment calls
Quote stage — the proforma invoice. The supplier's pre-order quote document: prices, quantities, terms. You use it to budget, to wire the deposit, and to lock what the commercial invoice will later say. If the numbers are sloppy here, they'll be sloppy everywhere downstream — what a proforma invoice is and isn't covers the uses in detail.
PO stage — your purchase order. The one document you author, and the reference every other document must match: product codes, quantities, prices, the manufacturer's legal name and address (which the ISF will need later), ship-to address. A PO is a document-generation habit as much as a contract — the purchase order process walks the full cycle.
Production — spec confirmation. Paperwork is thin here by design: an approved sample reference and a written spec sheet. The judgment call is refusing to accept "it's basically the same as last time."
Pre-shipment — inspection report and ISF. Two things happen in the weeks before loading. First, if you use third-party inspection, the report comes back at 80%+ production — the QC inspection checklist is what the inspector should be working from. Second, the ISF gets filed before loading: for ocean cargo, the first eight data elements are due no later than 24 hours before the goods are laden aboard the vessel at the foreign port. Most of that data — manufacturer, origin, HTS — comes from your supplier, which is why it belongs on your PO, not in a last-minute email. ISF filing explained covers all ten elements.
Booking — the shipper's letter of instruction. Some forwarders ask for a written SLI confirming routing, terms, and parties; treat it like any other "confirm what you actually agreed" document and read it before signing.
Loading — the bill of lading. The carrier issues the BOL when the container is loaded: it's the contract of carriage and the title document, and it must name the right consignee and notify party. Check it against the PO when the draft arrives — the bill of lading guide covers what each field controls.
Transit — the quiet stage. Nothing new lands on your desk, which makes it the right moment to reconcile: does the commercial invoice match the PO? Does the packing list match the BOL carton count? Fixing a document mismatch mid-ocean is a nuisance; fixing it at entry is an exam.
Arrival — arrival notice, entry, duties. The carrier or forwarder sends the arrival notice. Your customs broker files the entry using the commercial invoice, packing list, and bond, and duties and fees are assessed and paid before release. The judgment call: responding to the arrival notice the day it arrives, because storage free-time clocks start around now.
Delivery — delivery order and POD. The delivery order authorizes the trucker to pick up the container; you sign the POD at the dock. Then one habit: count cartons against the packing list before signing, or before filing any claim later.
Forwarder vs broker: the clarification everyone skips
Two professionals, two different jobs, endlessly confused because some companies do both:
| Role | What they do | What they don't do |
|---|---|---|
| Freight forwarder | Books and moves the freight: booking with the carrier, BOL coordination, arrival notice, delivery order; often files ISF as your agent | Files your customs entry only if it is also a licensed customs broker |
| Customs broker | Files the entry with CBP, handles classification, coordinates duty payment | Doesn't book vessels or move containers |
The practical instruction: confirm which one you have, in writing, before the first shipment. "My forwarder handles customs" is an assumption that fails quietly until arrival day, when nobody has filed an entry. Some forwarders employ licensed brokers; some brokers partner with forwarders; some do neither and expect you to arrange the other half. Ask the direct question — "who files the entry, and who moves the container?" — and record the answer with the shipment.
What to keep, and where
Per shipment, keep one folder (digital is fine) with: proforma, PO, spec sheet, inspection report, ISF confirmation number, BOL, commercial invoice, packing list, certificate of origin, bond reference, arrival notice, delivery order, and POD. Two habits make the folder earn its keep:
- Reconcile at receiving. Count cartons against the packing list and BOL, and note discrepancies on the POD before signing. Shortage claims built on a signed-clean POD are much weaker.
- Match everything against the PO. The PO is the spine. Quantities, prices, product codes, and the manufacturer details on every other document should trace back to it — divergence between documents is a classic exam trigger, and reconciliation is how you catch it before CBP does.
Common questions
What documents do I need to import goods into the US? At minimum: commercial invoice, packing list, bill of lading, the ISF filing before loading (ocean cargo), and a customs bond for formal entries. Upstream you'll handle a proforma invoice and your own PO; at destination, the arrival notice and delivery order. Some goods also require a certificate of origin or other permits.
Who issues the commercial invoice — me or my supplier? Your supplier, as the exporter, issues it, and your customs broker uses it for valuation at entry. Check it against your PO before it's used — quantities, unit prices, and terms. Wrong values mean wrong duties and CBP problems that outlast the shipment.
Is a proforma invoice the same as a commercial invoice? No. The proforma is a pre-order quote document used for budgeting and deposits; the commercial invoice is the transaction document customs uses for valuation at entry. The numbers should match, but they belong to different stages of the shipment.
Do I need a customs broker or a freight forwarder? They do different jobs: the forwarder books and moves the freight, while the broker files the customs entry and coordinates duties. Some companies do both — confirm in writing which yours is before the first shipment, or arrival day will tell you the hard way.
When should the packing list be ready, and who checks it? The supplier issues it and it travels with the shipment; your broker uses it at entry and you use it at receiving. Carton counts must match the BOL and what's actually in the container — count against it before signing the POD, since that signature anchors any shortage or damage claim.
Next step
Save the timeline table as your per-shipment checklist and run your next shipment against it stage by stage — the fastest way to find your gap is to fill in "when we actually do this" next to each row. Start at the stage you've never formalized: if the quote stage is email chaos, start with the proforma invoice; if pre-shipment is the blind spot, start with the ISF filing. The document that starts the timeline — the PO itself — has its own field-by-field guide in the purchase order template. And if a container ever goes missing into an inspection queue, customs exam fees covers what that detour costs.
