A production line waiting for a critical component, a retailer facing a stock gap, or a customer contract dependent on a fixed delivery date can quickly turn an overseas purchase into a time-sensitive logistics movement. Knowing how to arrange import air freight means controlling more than the flight itself. It requires accurate shipment data, compliant documentation, customs preparation and a clear handover from the overseas supplier through to final delivery.
For UK importers, the strongest results come from planning the movement before cargo reaches the origin airport. Decisions made at this stage affect airline acceptance, customs clearance and whether goods can leave the destination terminal without delay.
How to arrange import air freight: start with the shipment brief
An air freight forwarder needs a complete and accurate shipment brief before it can confirm a workable routing. The basic details are the collection address, destination address, cargo-ready date, commodity, number of packages, dimensions, gross weight and required delivery deadline. It is equally useful to state whether the shipment is stackable, temperature-sensitive, high-value, oversized or subject to particular handling requirements.
Dimensions matter as much as scale weight. Air freight is charged and planned using chargeable weight, which may be based on the volume occupied by the shipment rather than its physical mass. A compact but heavy consignment may move very differently from a light, palletised shipment that occupies substantial aircraft space. Precise measurements also allow the forwarder to identify whether cargo will fit standard airline equipment or needs specialist planning.
The commercial terms agreed with the supplier should be confirmed at the same time. Incoterms determine which party is responsible for collection, export formalities, main carriage, insurance and import clearance. A vague instruction such as “send it by air” leaves room for costly assumptions. Establish who controls each stage and who is authorised to provide instructions before collection is arranged.
Check the commodity before cargo is booked
Not every product can be accepted as general cargo. Goods containing lithium batteries, chemicals, aerosols, liquids, magnetic materials or pressurised items may be regulated as dangerous goods. Some products are permitted by air only with approved packaging, declarations, labels and specific handling procedures. Others may require a different transport solution.
Businesses shipping regulated cargo should also read How to Ship Hazardous Materials by Air, which explains how dangerous goods are assessed before airline acceptance.
The correct question is not simply whether a product is dangerous. It is whether its composition, quantity, packaging and transport status have been assessed correctly. Safety data sheets, battery test information and manufacturer specifications may be required before an airline will accept the booking.
Certain goods also need import licences, health certificates, phytosanitary documentation or other regulatory approvals. This can apply to food products, plants, animal-origin goods, controlled technology and regulated industrial materials. A customs entry cannot resolve a missing import permit after the goods arrive. Compliance checks should therefore begin while the supplier is preparing the consignment.
Prepare commercial and customs documentation
Documentation creates the audit trail for an import movement. The commercial invoice should clearly show the buyer and seller, a meaningful description of the goods, quantity, unit and total value, currency, country of origin and agreed Incoterms. Descriptions such as “parts”, “samples” or “equipment” are often too broad for customs classification and can cause queries.
A packing list should match the physical cargo. It should identify package numbers, contents, weights and dimensions, particularly where a shipment includes several cartons, crates or pallets. This helps the handling agent check cargo at the terminal and helps the importer investigate any discrepancy.
For UK imports, the importer must also provide its Economic Operators Registration and Identification number, known as an EORI number, and sufficient information to determine the correct commodity code, customs procedure and declared value. The commodity code affects duty treatment, import controls and statistical reporting. The declared customs value may include more than the invoice value, depending on the transaction and Incoterms.
Our guide to Air Cargo Customs for Commercial Shipments explains how customs classification and declaration accuracy help prevent avoidable clearance delays.
An air waybill is produced for the cargo movement once shipping instructions are agreed. It records the parties, routing, pieces and weight, and acts as the operational reference used by airline and handling teams. It is not a substitute for a commercial invoice or a customs declaration, but all documents must be consistent. Mismatched weights, values or consignee details create avoidable clearance risk.
Select a service level around the real deadline
Urgency should be measured against the required delivery time, not only the desired departure date. A direct flight may offer the shortest transit time, but capacity can be limited. A routed service may be more practical for regular commercial cargo, provided the connection time and terminal process still meet the delivery requirement.
Collection timing also matters. Cargo must be collected, security screened, delivered to the origin terminal and accepted before the airline’s cut-off.
Understanding Air Freight Cut Off Times Explained can help importers avoid missed departures caused by late documentation or supplier delays.Late supplier readiness is a common reason why an apparently booked movement misses its intended flight. For critical shipments, the collection plan should include a realistic margin for packaging completion, documentation review and origin handling.
Consolidated air freight can be an effective option when timing allows cargo to move with other consignments. A dedicated or priority service may be more appropriate where a production stoppage, contractual deadline or high-value item requires tighter control. The right choice depends on the commodity, route, service requirement and available capacity, rather than a single standard transit promise.
Arrange origin collection and airport handling
Once the booking is confirmed, the overseas supplier needs clear collection instructions. These should include the collection date, packaging standard, labels, documentation to travel with the cargo and the contact details for the collection point. If the shipment will be palletised or crated, this should be agreed in advance. Poor packaging can lead to damage, airline rejection or a requirement for repacking at the airport.
At origin, cargo is weighed, measured, screened where required and accepted by the handling agent. The airline may reweigh or remeasure the shipment, so the final chargeable weight can differ from an early estimate if the supplier data was inaccurate. A forwarder should monitor this stage and advise promptly if the planned uplift is at risk.
Clear UK customs before arrival where possible
Customs clearance should be prepared before the aircraft lands, not treated as an administrative task after arrival. With complete documents and confirmed customs instructions, a declaration can often be submitted in advance. This supports faster release once the goods are presented to customs.
The importer should be clear about how duty and import VAT will be handled. Depending on the business’s VAT position and the customs procedure used, import VAT may be accounted for through postponed VAT accounting rather than paid at the border. Duty, where applicable, is determined by the commodity code, origin, customs value and any available preference arrangements. Evidence of origin may be needed to support preferential duty claims.
Customs authorities can select consignments for documentary checks, examination or inspection. No forwarder can remove that possibility, but accurate declaration data and complete supporting documents reduce the chance of delays caused by preventable queries. Where an issue arises, a single operational contact who can coordinate the supplier, customs agent, terminal and consignee is valuable.
Plan release, collection and final delivery
Cargo is not ready for delivery simply because the flight has landed. It must be unloaded, moved into the terminal system, presented to customs and released by both customs and the handling agent. Terminal storage periods are limited, so final delivery should be arranged around the expected release date and any delivery-site restrictions.
Confirm the delivery address, opening hours, vehicle access, unloading equipment and named receiving contact in advance. A palletised shipment may require a vehicle with a tail-lift or a site with forklift capability. High-value, sensitive or urgent goods may need timed delivery, secure handling or a direct vehicle rather than a standard delivery schedule.
Proof of delivery should complete the operational record, alongside the air waybill, customs entry and final invoice documentation. These records support stock control, VAT accounting, supplier management and future shipment planning.
Use visibility to improve the next movement
Import air freight is often arranged under pressure, but repeat shipments benefit from a standard process. Keep a verified commodity database, agreed supplier packing instructions, current importer details and a documented customs approach. This reduces the need to rebuild critical information every time a shipment becomes urgent.
ACS Air Freight coordinates airline bookings, compliance checks, customs formalities, airport handling and final delivery through a single point of contact. For an importer, that operational ownership helps turn multiple handovers into one controlled movement.
The most useful next step is to create a shipment brief before the supplier confirms cargo readiness. When the commodity, documents, customs instructions and delivery requirement are known early, air freight can be arranged as a planned supply chain decision rather than an expensive response to a missed deadline.
