What types of cargo do you handle?

Do you provide customs clearance services?

Yes. Our team manages all necessary import and export documentation, customs processing, and regulatory compliance to ensure smooth clearance.

What are the risks of maritime freight transport?
  • Delayed shipment: The most common causes of delay are inefficient management of port times and formalities. Other variables may also affect the shipment, such as circumstances of force majeure, like a storm for instance, or, in some parts of the world, the risk of a pirate attack.
  • Lost goods: While this represents a very low risk today, it can occur in the event of problems such as the boat sinking or breaking down, as well as due to robbery or theft in ports of loading and destination in countries with high levels of corruption.
  • Moisture, humidity or extreme temperatures: Environmental conditions must be perfectly controlled to prevent the cargo from being rendered unusable due to moisture, humidity or extreme heat or cold. All cargo must therefore be transported in containers suited to their particular characteristics and checked to ensure that they are properly closed. They must also be correctly loaded, unloaded and stored.
  • Contamination: Interaction between different goods can ruin them. The goods must therefore be well packaged and properly stowed in the hold to prevent their contamination.
  • Natural disasters: Natural disasters are becoming more frequent and serious in recent years; this represents the most unpredictable risk on the list.
  • Computer threats: This is one of the new risks of international maritime transport since the famous NotPeya attack suffered by Maersk. Companies and ports are therefore currently working on logistics cybersecurity.
What kind of maritime transport vessels exists?

We can distinguish between different kinds of ships for maritime transport, depending on the load they transport:

  • General freighters: These are basic cargo ships; they can carry freight, but have no space for containers.
  • Container ships: Ships specially designed to carry goods in containers. They monopolize the majority of international dry freight transport and represent more than a half of all maritime trade.
  • Bulk carriers: The vessels best suited to transporting solid bulk cargoes.
  • Oil/gas tankers: Special tankers for transporting crude oil and by-products differentiated by their superior technical characteristics; all of them guarantee water tightness and structural resistance. Gas tankers have more sophisticated technology for storing liquefied gas and are divided into carriers of GNL and GLP, given that each one needs to be kept at a different pressure and temperature.
  • Reefer ships: Transport perishable food and commodities which must generally be preserved at very low temperatures
  • Ro-Ro ships: Have ramps and platforms for transporting vehicles with wheels, from private cars to industrial vehicles and loaded trucks. There are also hybrid versions of these ships which combine vehicle and passengers transport (ferries) and others that transport vehicles carrying containers (Ro-Lo)
How long does air freight delivery take?

Air freight delivery times vary by destination, but most international shipments arrive within 1–5 business days, depending on route and customs procedures.

Is ocean freight more affordable than air freight?

Yes. Ocean freight is generally more cost-effective for large or heavy shipments, while air freight is ideal for urgent or high-value cargo.

Can I ship small packages through Zonal Express?

Absolutely. Our courier delivery service is designed specifically for documents and small parcels requiring fast and secure delivery.

How do you calculate the cost of air charter?

An air charter service is calculated based on the volume of the goods transported. However, it is strongly influenced by the availability of physical means (transport) on your desired route. By way of an example, bringing goods from China is much cheaper than it is to take them there. This is because shipowners are in high demand for bringing cargo from China to Europe, while it is more complicated to find freight to transport back out to China given the existing trade imbalance. Another variable with a strong influence is the oil price at the moment of travelling.

What documents are required for air freight?
  • Air Waybill (AWB): This is the document of title to the goods travelling by air and is therefore non-negotiable. It travels with the cargo and acts as evidence of delivery of the goods travelling on board the plane.
  • Commercial invoice: Document establishing the conditions of sale for the goods and their specifications. Serves as proof of sale.
  • Packing list: A list of the contents in a package, completing the information of the invoice, which must be issued by the sender.
  • Customs clearance authorization: Document with which an importer or exporter authorizes a customs agent to submit one or several customs declarations on their behalf.
Do you offer door-to-door delivery?

Yes. Zonal Express provides complete door-to-door logistics, handling pickup, transport, customs clearance, and final delivery.

Are my goods insured during transit?

Yes. We offer cargo insurance options to protect shipments against loss, damage, or unexpected incidents during transit or storage.

How do I book a shipment?

You can book shipments online through our website, request a quote first, or contact our logistics team for customized booking assistance.

Do you handle temperature-sensitive cargo?

Yes. We provide specialized handling for temperature-controlled shipments including pharmaceuticals and perishable goods.

What is customs management?

The management of all formalities required by the customs authorities. It is important for these formalities to run smoothly and trouble-free in order to prevent delays due to bureaucratic issues. These formalities are therefore usually entrusted to a customs agent who will carry them out on behalf of the freight owner.

What is customs clearance?

All formalities and requirements to be completed for goods entering and leaving a specific national territory in order to control and approve their transportation. The customs agent is responsible for completing these formalities on behalf of the importer or exporter, and for submitting a declaration of information to the competent customs authority in each case.

What is completed customs clearance?

Customs clearance means that the customs procedure has been completed, i.e. that all of the paperwork has been submitted and that the shipment can continue on its way.

How do customs controls function?

Customs control the movement of goods between different states in three steps:

  1. Customs declaration: Must be presented to the customs authority in order to identify the goods to be transported and their destination.
  2. Goods inspection by the customs agents, to check that they match the declaration.
  3. Verification that trades policy norms have been met and amounts due have been paid (import and export duties).
