Approve the export data of a style before it goes on sale

7 min read · September 2026

Use this guide when the broker's question arrives after the parcel

A boutique in another country has ordered, the cartons are packed and the courier comes this afternoon. The documents that travel with those cartons draw on facts decided months earlier, in development and at the manufacturer. Those facts are approved by a named person, on a date you can choose, and the paperwork is then assembled from data that already exists.

You sell wholesale to buyers in more than one country and you have no customs department. You do that work yourself, or one person handling sales admin does it and also answers the carrier.

You recognise the situation by the question that arrives after the goods have left: what is this made of, where was it made, what code did you use, what does one piece weigh. At that point the parcel is with the carrier and the answer is put together under time pressure.

Two kinds of data on every export document

An export document draws on two sets of facts with different lifespans.

The first set describes the goods: a customs description in plain terms, the tariff code, the country of origin and the net weight. These are properties of the style — a woven cotton jacket is woven and cotton on every shipment it goes on.

The second set describes this sale: the buyer, their country and tax status, the currency, the quantities actually packed and the gross weight of the cartons.

Described in words

An export document draws on two sets of data. The product record carries what the goods are — the customs description, the tariff code, the country of origin and the net weight — and it is approved once per style. The order and the shipment carry what is being sold this time: the buyer, the country, the currency, the quantities and the gross weight. Every document you send with a parcel is a combination of the two.

Three of those first-set fields mean something narrower than their everyday names.

  • Country of origin is the country where the goods were last substantially processed under the rules of origin. A dress sewn in Italy from fabric woven outside the EU may have an origin other than Italy. It is a different fact from the country the parcel is sent from.
  • The tariff code has a six-digit core shared internationally and a longer extension set by each destination. The EU extends it to eight digits; other countries extend it their own way.
  • Construction and composition decide the code for clothing: knitted or woven, the fibre mix, the purpose of the garment and who it is made for. None of that can be read off a marketing name.

Commercial invoicethe document that describes the transaction, the goods and the value for customs. It may be the same document as your sales invoice, or a separate one; the authorities in the destination country decide what they need to see.

When each field has to be approved

Everything in the first set can be approved once, and the last point at which that happens without pressure is when the style opens for sale. From the confirmed order onwards, every field is a fact about one shipment.

Described in words

The customs description, the tariff code, the country of origin and the net weight belong to the style, so they can be approved once — and the last point at which that happens without pressure is when the style opens for sale. From the confirmed order onwards, every field is a fact about one shipment: who is buying, in which country, how many pieces and what the cartons weigh. A style that reaches the packing table without approved customs data is approved under time pressure, by whoever is at the desk.

Approval means a named person and a date, because the code is a judgement. A tariff chapter is the top-level group of the code, and garments fall into a different chapter depending on whether they are knitted. The position of a 50/50 blend depends on which fibre is heavier by weight; a knitted lining inside a woven jacket leaves the jacket in the woven chapter. Two colourways of one style are often cut from different fabrics, so the code belongs to the colourway.

ExampleCollection 0112_ARD has the MERU jacket in two colourways. Ecru is woven, 100% cotton, 450 g. Navy is knitted, 70% wool and 30% polyamide, 520 g. They fall into two tariff chapters, so they need two codes, two descriptions and two weights — one style, two approvals.
In go4The customs card on a product calculates a code per colourway from the category, the construction of the main fabric and the predominant fibre, and states its reasoning next to the result. It stays "Proposed" until someone presses "Confirm & save", which records who confirmed it and when. Only a confirmed code reaches a document. Where data is missing, the card names the missing field. The code is a proposal prepared from your data; a binding classification is issued by a customs authority.

What the buyer's country changes

The country and the tax status of the buyer decide which documents you issue and which proof you have to collect afterwards.

Where the buyer isWhat you issueWhat you collect afterwards
Your own countryyour normal sales invoicenothing beyond the invoice
Another EU member statea sales invoice at the zero rate, which is a supply taxed at 0% with the tax accounted for by the buyerevidence that the goods reached the other member state
Outside the EUsales invoice plus the customs set: commercial invoice, packing list, item lines (the per-item customs data the carrier files)confirmation that the goods left the EU
Regional scopeThe three rows above are EU constructions for a seller established in the EU, as the rules stand in September 2026. The evidence that qualifies, and the form your tax invoice has to take, are set by the member state you are established in. In Poland, for example, the e-invoicing rules phased in during 2026 cover intra-EU supplies and exports. The document still reaches a foreign buyer outside that service, and the customs set stays a separate obligation. The import requirements of the destination are set there: the United States asks for a sufficient description, quantity, value and an eight-digit subheading; Canada defines its own field set; Japan pairs the invoice with transport documents and, depending on the rate claimed, evidence of origin. Check the route with your customs agent before the first shipment to a new country.
DecisionUnder DAP (delivered at place) the buyer clears the goods for import and pays the duties. Under DDP (delivered duty paid) you do, which requires you to be able to act as importer in that country — a registration you may not hold. Agree the terms on the order, not at the packing table, and check that you can meet them.
In go4When you issue the final invoice from an order, the document kind follows the buyer's country, whether the buyer is a company and whether a tax number is on file, and the reason for the choice is recorded with it. For a destination outside the EU customs union, the shipping drawer adds a "Customs" section with the reason for export, the delivery terms, the tax numbers and the item lines. You decide the value of the shipment and who acts as importer.

One data set, four documents

Quantities, values, weights and descriptions appear on the invoice, on the packing slip, on the item lines for the carrier and on the label. When those four are typed separately, they can differ, and carriers name incomplete or inconsistent documents as a cause of clearance delays.

The boutique in Zurich ordered 16 MERU jackets in Navy and 10 LOVAT bags in Black. That is one shipment with two lines, two codes and a net weight of 16 × 520 g plus 10 × 380 g, or 12.12 kg before packaging. Every document in the set carries the same two lines and the same weight.

In go4The packing screen records which piece of which variant, from which lot, went into which carton, and the carton carries its own weight. From that one record go4 produces the invoice with the customs description and code on the line, the packing slip, the item lines for the carrier and the label. Since invoices are issued per shipment, an order that travels in two parts has a document for each part.

Check before the carrier takes the parcel

After collection, a correction costs a call to the broker, a delay and often a fee. Before collection it costs a minute.

In go4Before a courier can be booked, one check runs over the shipment and lists what is missing, with the name of the field and where to fix it. An incomplete address, a carton without a weight or, outside the EU, a line without a confirmed code block the booking. A missing tax number for the recipient, a missing registration number of the exporter with customs or a missing invoice for that shipment warn without blocking.
ImportantA complete document set does not prevent random, product or sanctions checks. It removes the delays that come from the paperwork.

Close the transaction with the proof

For an intra-EU supply, the zero rate depends on evidence that the goods reached the other member state, as the rules stand in September 2026. For an export, it depends on the customs confirmation that the goods left the EU. Both arrive after the parcel has gone, and both belong to a specific invoice and specific lines.

The deadline for holding that evidence, and what happens when it arrives late, are set by the member state you are established in. In Poland, for example, the supply is taxed at the domestic rate until the proof arrives and the filing is corrected.

Make the return of the proof a step in the shipping routine, with an owner and a date next to the deadline of your filing period. Confirm the evidence your own filing needs with your tax adviser.

ImportantA product in go4 carries one country of origin. When a product has none, the item lines for the carrier fall back to the country the parcel is sent from, which is a different fact. Fill in the origin on every style you export.

Two rows of that table are worth a routine of their own. Keep a list of styles whose customs data is incomplete, reviewed when a collection opens for sale, and a list of zero-rated shipments whose proof has not arrived, reviewed before each filing deadline.

You are done when

Every style you export has a customs description, a confirmed code per colourway, a country of origin and a net weight, all approved before the style went on sale. Booking a courier raises no blocking message. For each zero-rated shipment you can point to the document that proves delivery or export, and to the invoice it belongs to.
