When organizing a new transport operation, it is very common to have questions. Whether it is because you’re starting a new line of business or because you simply don’t know how to send a shipment, these common questions and answers can help you in the process.

AEO (Authorized Economic Operator, or OEA in Spanish) is a status that can be obtained by EU economic operators that wish to become EU-trusted operators in their professional customs activity.

Not necessarily. When you place a shipping order with us, the order itself is considered a shipment contract and an implicit acceptance of our general conditions.

MARESA LOGISTICS runs all of its groupage and container services directly to each destination island from each delegation, saving time and increasing expedition security by avoiding unnecessary handling.

The average delivery time in the archipelagos is:

  • Canary Islands: Depending on the requested service, from 3 days to 1 week.
  • Balearic Islands / Ceuta / Melilla: From 24 hours.
  • Courier and Air Services: From 4 hours.
  • Other destinations: Depending on location.

This is an international rule that applies to transportation. Calculating by weight or by volume is determined by the goods occupying the most space in the transport unit.

Transport units, maritime or air containers, have a cost/profitability ratio. Therefore, units are required to be filled to their maximum weight or volume.

There are low-weight and high-volume goods, which means that even if a container or a truck hasn’t reached its maximum weight, there might not be any more space available. In those cases, expeditions will be by volume.

To summarise:

  • If when converting volume to weight, the result is greater than the actual weight, the shipment will be processed by volume.
  • If when converting volume to weight, the result is less than the actual weight, the shipment will be processed by weight.

The weight-to-volume ratio is as follows:

  • Maritime transportation: 1 m3 = 333 kg.
  • Air transportation: 1 m3 = 167 kg.
  • Road transportation: 1 m3 = 270 kg.

In full shipments or single expeditions for a customer there are generally no restrictions. However, certain permits or special requirements might be needed in cases like ADR, special measures, etc.

For groupage services (LCL or Less than container load), ADR goods, animals, human remains, wet goods, or those from which liquids may spill are excluded.

In all shipments, any expedition that is against the law or good practice are forbidden.

Only deliveries to front doors or doors/gates that are authorized to receive deliveries. Basements, apartment buildings and interior locations are excluded.

Unpacking and waste collection tasks are excluded.

Complying with customs requirements, the shipper must present the following along with any goods:

On May 14 2004, the application of the new National Aviation Safety Plan (PNS) began. The PNS establishes a control process to prevent prohibited items from being transported, i.e. objects that may be used to commit illicit acts and items whose transportation or tenancy is not authorized.

The Canary Indirect General Tax (most known as IGIC) is a state tax of indirect and general nature that applies to the delivery of onerous goods and services by employers and professionals on a regular or occasional basis. It also applies to imports of goods, whatever the importer’s condition, made in the Canary Islands.

  • Reduced: 2%
  • General: 5%
  • Increased: 9% and 13%

R.M (Retail Surcharge)

This tax applies to all Canary companies that are considered retailers. It is due to the concurrency of requirements for the tax liability subject. This way, retailers are those businesses which, in the previous calendar year, have sold more than 70% of their sales volume of movable or semi-movable goods without prior transformation, mainly to individuals or to the Social Security in establishments located in the Canary Islands.

Type of levy:

  • A fixed 10% is applied on the IGIC tax settlement.

  • 5 % of the invoice value of the goods.
  • 15% of the invoice value of the goods.

  • Maritime and road transport: 5.86 eur/kilo transported. (Law 15/09 on the contract of carriage of goods).

All-risk insurance

This covers the total value of the goods in the following premiums:

  • Sea and land transport: 0.7% and fragile at 1%.
  • Air transport: 1%.

The insurance premium is on account of the value of the goods, therefore the cost of transport and taxes are excluded.

As a general rule and unless otherwise indicated by the customer, as follows:

  • Maritime service: Always on groupage shipments and never on full container shipments, unless specifically requested.
  • Air service: Never, unless specifically indicated.
