Why I call it a game
I come from planning. To me, importing used to be one number in a spreadsheet: the supplier lead time, say 45 days, and that was it. When I started following shipments up close, I saw that this number hides a whole board.
Every step has an owner, a document and a deadline. Some failures only cause delays. Others send the cargo back to origin. This was the path I followed on every shipment:
| Step | What happens | What can go wrong |
|---|---|---|
| Order | The monthly order goes to the factory with quantities per item. | A non-standard item with no prior alignment. |
| Factory and documents | The factory produces and sends the invoice, packing list, shipping list and certificate of analysis. | Mismatched quantity, batch, expiry or tax ID. The cargo does not even ship. |
| Import approval | For some products, the import depends on an ANVISA approval for that operation. | A batch made before the approval date. |
| Freight | The Incoterm says who books it. Under EXW or FCA, it is the importer. | An expired quote and higher freight. |
| Shipping | Air waybill (AWB) check and flight. | A description that differs from the documents. After take-off, there is rarely time to cancel. |
| Arrival | The cargo waits in the airport bonded warehouse until it is cleared. | Every day there is a storage fee. |
| Channel | The import declaration (DUIMP) is assigned a channel. | Yellow or red: more checks, more days. |
| Damage | The warehouse reports damage on arrival and the customs broker asks for a reply. | With no reply, the process moves on and the evidence for insurance is lost. |
| Entry invoice | After clearance, the entry tax invoice (NF) is issued and transport is booked. | A late NF keeps the cargo at the airport, still paying storage. |
| Stock | Delivery to the logistics provider and batches entered in the system. | Only here does the product become available stock. |
What taught me the most
The invoice date is not always the flight date
It was one of the first details I learned. The invoice has a shipping date field, and I used it to project arrival. In many cases, though, it marks the day the order was loaded into the supplier's system. The real departure was on the air waybill or in the forwarder's follow-up.
It sounds minor. But the arrival forecast feeds coverage, backorders and replenishment priority. A wrong date at the start spoils everything after it.
When we pay the freight, the quote expires
With suppliers on EXW or FCA, the importer books the freight. Forwarder offers are valid for a few days. If internal approval runs late, the offer expires and the new one is usually more expensive, sometimes with a different route. I learned to compare proposals by checking that all of them include pickup, export clearance and documents, and to remember that air freight is charged by volumetric weight.
The batch that had to go back
It was the most expensive case I followed. Some healthcare products need an ANVISA approval for each import, and only batches made after that approval date are accepted. A batch made before it shipped, reached Brazil and had to go back to origin.
Before approving a shipment, I started asking for the document with the batch number and manufacturing date of each item and comparing it with the approval date. That comparison became one of the rules in the document checker I wrote in Python. Once the plane takes off, between time zones, connections and holidays at origin, there is rarely time to cancel.
Consolidate or split shipments
This decision came up every month. Putting items on one shipment saves freight. But if one item gets stuck in inspection, everything waits with it, including the item that was urgent to close the quarter. Demo products, which come in under temporary admission and must go back, I learned to never mix with registered products.
The air waybill description
The cargo description on the AWB must match the documents and the inspection report from origin. Rewording it to "make things easier", or adding a brand name, is often rejected at origin and can turn into a requirement on arrival.
When the cargo arrives
Landing in Guarulhos does not mean the cargo is yours. It stays in the bonded warehouse until clearance, and every day has a storage cost.
The import declaration is assigned a channel. Green clears directly. Yellow means a document review. Red adds a physical inspection. There is also grey, which is rarer and used when the declared value is under suspicion.
If the warehouse reports damage, the customs broker asks for a reply, usually within 24 hours. To avoid missing that window, I built a Power Automate alert that posted to Teams whenever a request from the broker came in. Replying the same day and keeping the email and photos is what supports an insurance claim.
Once cleared, the purchase order goes into the system with the invoice number and the entry tax invoice is issued. Until it is, the cargo stays at the airport, still paying storage. Only after receipt at the logistics provider, with batch, manufacturing and expiry dates checked, does the product become available stock.
My checklist before approving a shipment
- Invoice, packing list, shipping list and certificate of analysis checked: quantities, batches, minimum shelf life and tax ID.
- Departure date taken from the air waybill or follow-up, not from the invoice.
- Incoterm read: who books the freight and how long the quote is valid.
- Products with import approval: manufacturing date of each batch compared with the approval date.
- Unregistered products kept off shipments with registered products.
- Air waybill description matching the documents and the inspection report.
- Damage reports answered within 24 hours, with the evidence kept.
- Purchase order and entry invoice done without delay after clearance.
What I take from that period
International trade is a chain of deadlines. Every document requirement becomes days of storage and a risk of running out of product at the end of the line. For planners, the lesson is easy to say and hard to practise: the supplier lead time is only part of the time. The steps in the middle count too.
