Which documents do I need to import goods?

Generally speaking, the three documents most commonly required for any kind of import are the Commercial invoice, List of contents, Certificate of origin and the Contract for the international carriage of goods (B/L, CMR, AWB, etc.)

We recommend including the Harmonised System tariff code on the invoice. This code consists of a minimum of 6 figures that classify the shipment precisely. The documents should also include the INCOTERM and the financial information and commercial links between seller and buyer.

The List of contents should specify the measurements, weight and contents of each package transported.

As for the Certificate of origin, different types exist depending on the specific goods and country of origin, for the purpose of achieving tariff benefits in accordance with international trade agreements.

Other documents include those that are specific for each type of goods (health certificates, veterinary, dual-use technology, metrology, alcohol guides, etc., etc.)

For all your specific requirements, INTERTRANSIT has a team of professionals who can advise you on all the different requirements, to help you process your imports rapidly, economically and securely.

What are the main types of shipping containers?

Shipping containers are manufactured in accordance with ISO regulations, and can be divided up into different types according to certain criteria, mainly relating to volume and type of load. These standardised container sizes mean that multimodal transport can be carried out throughout the world.

They can be manufactured from different types of materials to protect the goods (i.e. steel, aluminium and wood), and they can be refrigerated, hermetically sealed, etc.

This table in a pdf document provides further detailed information on the most common shipping containers.

Alternatively, if you are interested in air shipment containers, you can find the information in this table.

If you have any further queries, please get in touch with our air and shipping department.

What are Incoterms?

International Commerce Terms, or Incoterms, are three-letter acronyms that define the costs and responsibilities assumed by the seller and buyer when carrying out an international goods shipment. While not compulsory, they are of great practical use in international commercial operations.

To choose the most suitable one, we must consider such important issues as type of goods, type of transport to be used, who must contract and pay for said transport, who will cover the cost of insuring the goods, who will be responsible for customs payments and taxes, and where and how the goods shall be delivered.


This table provides a detailed schematic representation of how Incoterms function.

Who must submit an Intrastat declaration?

The Consignee or Expediter who carries out exchanges of goods with other EU Member States, providing that the value of said goods is above the exemption threshold during a tax year. In this case, a monthly statistical Intrastat declaration must be made.

In Spain, the Agencia Tributaria (State tax department) is responsible for setting the exemption (or compulsory) threshold.

INTERTRANSIT will prepare and submit your INTRASTAT declaration telematically, as well as your Recapitulative Return on Community Operations Document (Form 349). For further information, contact our technical and customs department.

So you can check on the status of your delivery or stock at all times.

How can I calculate the m3 of my shipment?

Calculating the volume of your goods shipment is simple – all you have to do is multiply the following measurements: length x width x height. The resulting figure is the m3 of the shipment.

Using the volume obtained, you must then calculate the Volumetric Conversion to obtain the Volumetric Weight of your shipment, according to the type of transport to be used for your shipment.

  • Shipping: 1 m3 = 1000 Kgs.
  • Road: 1 m3 = 333 kgs.
  • Air: 1 m3 = 166,66 Kgs.

The Chargeable Weight (for applying rates) shall be the highest figure out of either the Gross Weight or the Volumetric Weight.

For your convenience, we include here a complete volumetric conversion calculator to help you calculate, quickly and easily, the m3 of your shipment.
