Gibraltar Customs Clearance

Gibraltar’s new customs and trading arrangements have been in operation since 15 July 2026. This living operational guide tracks what is happening in practice: Commercial Gate conditions, customs processing, documentation problems, official guidance and the practical lessons emerging for importers, retailers, freight operators and customs representatives.

The page will be reviewed weekly and updated earlier where material official guidance or a significant operational change is published. Detailed explanations of the underlying rules remain available in Gibraltar.com’s Gibraltar Treaty Update: Practical Terms and Transaction Tax on Imported Goods guides; this page is intended to show how the system is working in practice.

Operational Status

What Changed This Week

Freight delays are easing, but operations are not yet normal

After several days of disruption, freight movement began to improve by Friday 24 July. The Commercial Gate remains operational. Around 170 trucks entered Gibraltar on 21 July and 184 on 22 July, compared with reported pre-Treaty daily volumes of approximately 230–250. The position is improving, but delays and reduced delivery capacity continue to be reported, and no official normal-processing benchmark has been published.

Medicine and food delivery problems have been identified, with corrective action under way

The Government confirmed on 23 July that two technical causes affecting medicines had been identified on the Spanish side and that the necessary corrections were being applied. The delayed chemotherapy consignment arrived, no patient treatment was affected and there was no concern over GHA or pharmacy stock levels. Food consignments of non-EU origin also resumed, although time-sensitive movements remain an area requiring close monitoring.

New Spanish transit validations and contingency plans are now in force

The Spanish Tax Agency published additional NCTS6 requirements on 21 July for T1GI and T2GI movements. From 22 July, declarations must include an Additional Supply Chain Actor with the role of consolidator, and the net mass recorded for goods within a referenced house consignment must match the net mass in the related import or export declaration. Contingency plans are also available for the designated customs posts at La Línea and Algeciras for use when the relevant customs applications are unavailable or affected by an IT incident.

Postal movements are now being routed by road through Spain

Postal items to and from Gibraltar are no longer moving directly by air under the previous arrangements and are instead being transported by road through Spain. Longer transit times have been indicated while the new route and Spanish-side operational procedures settle. Businesses and individuals relying on urgent post or parcels should allow additional time and review tracking and delivery expectations accordingly.

Government, Customs and business support is continuing

HM Customs officers continue to visit larger importers to guide them through the process, alongside the training already offered before implementation. Government, Customs, Spanish authorities, customs agents and freight operators continue to work through problems as they arise. The Business Transition Advisory Group has met following implementation, and a further meeting is expected in the coming weeks, but no date has yet been published.

What We Learned This Week

Customs clearance must start before dispatch

The frontier is the final stage of a wider customs process, not the place where that process should begin. Importers need to confirm the route, declarations, transit arrangements, data fields, tax treatment and responsibilities before the goods leave the supplier. The new Spanish NCTS6 validations make pre-dispatch checking even more important, particularly for groupage and consolidated loads.

Suppliers still need clear written instructions

Many UK, EU and overseas suppliers will not understand Gibraltar’s new procedures or the change to postal and overland routes. Importers should provide written shipping and documentation instructions rather than assume the supplier, carrier or postal operator already knows which information, codes and references are required.

Customs expertise has become an operational advantage

Businesses using experienced customs agents and customs-clearing services, supported by freight forwarders, couriers and logistics providers, are better placed to identify the correct transit procedure, apply current NCTS6 requirements, prepare declarations and resolve errors before a consignment reaches the Commercial Gate. For smaller importers, outsourcing the process may be more efficient than attempting to manage every declaration internally.

Product data must be accurate before goods are ordered

Generic descriptions, uncertain commodity classifications, missing origin evidence, incomplete values and mismatched consignment data can create delays. Businesses should maintain reliable product records covering description, classification, origin, customs value, applicable licences, certificate or exclusion codes, Transaction Tax treatment and, for consolidated movements, the required house-consignment and net-mass information.

Dispatch route and legal origin are not the same

Goods sent from the United Kingdom are not automatically UK-origin goods. A product manufactured elsewhere and distributed through the UK may remain a third-country product for customs purposes. The origin claimed must be supported by appropriate evidence, irrespective of whether the goods now reach Gibraltar by road, post or another permitted route.

Every party in the movement must be aligned

The supplier, carrier, consolidator, customs agent, transit guarantor, Spanish customs representative, Gibraltar importer and HM Customs may all form part of the same movement. A missing document, incorrect code, inconsistent mass figure or misunderstood responsibility at one stage can delay the entire consignment, even where the remaining documentation is correct.

Time-sensitive deliveries need a contingency plan

Importers of medicines, refrigerated products, fresh food and urgent operational supplies should identify named escalation contacts before dispatch. They should confirm how cold-chain integrity, storage and delivery timing will be protected if clearance is delayed. Businesses relying on urgent mail or parcels should also review lead times now that postal traffic is moving overland through Spain.

Just-in-time procurement may need temporary adjustment

Businesses operating with very limited stock may need to allow more lead time or hold a modest buffer while the procedures settle. Freight flow has improved but has not yet been shown to be consistently normal, and postal transit times may also be longer. This is especially relevant where a late delivery could interrupt healthcare, hospitality, retail, construction, workshop or professional operations.

Common Problems to Avoid

• Dispatching goods before the customs representative has reviewed the complete documents.
• Using vague invoice descriptions or incomplete product data that do not identify the goods sufficiently for classification and clearance.
• Assuming the country of dispatch is automatically the country of origin.
• Failing to agree who will lodge the EU transit declaration, the Gibraltar declaration and any related tax payment, or who will provide required consolidator data.
• Assuming every Gibraltar importer must obtain its own NIF and EORI when an agent may be completing and paying for the customs movement from the agent’s own account.
• Sending groupage, pharmaceutical, refrigerated, postal or other urgent consignments without an escalation contact and a plan for delay or system contingency.
• Pricing goods using a general percentage instead of the correct customs value, Transaction Tax rate, customs duty and excise treatment.
• Relying on pre-implementation summaries without checking current HM Government, HM Customs and relevant Spanish customs guidance.

Current Practical Guidance for Importers

Before a commercial consignment is dispatched, the importer should:

Businesses that need help interpreting customs valuation, Transaction Tax, commercial records or contractual responsibilities can also locate accountants and tax advisers and legal services through Gibraltar.com. All directory links are provided for information and ease of reference, not as recommendations.

• Confirm the commodity classification and Transaction Tax treatment for every product.
• Confirm whether the goods are EU-origin, UK-origin or third-country goods and retain the supporting origin evidence.
• Confirm whether the consignment falls within a transitional arrangement and retain evidence showing when movement began.
• Confirm the designated customs post and whether T1/T1GI or T2/T2GI transit procedures apply. For T1GI and T2GI declarations, check the current Spanish NCTS6 consolidator and net-mass validation requirements.
• Agree who will prepare and lodge each declaration and who is responsible for guarantees, duties, Transaction Tax and any consolidator or house-consignment information.
• Check whether a NIF, EORI, ASYCUDA registration or other access is required for the chosen arrangement.
• Send the customs representative the invoice, packing list, transport records, origin evidence, certificate or exclusion references and any required licences before dispatch.
• Check that the customs value includes relevant transport, insurance, commission, packing, duties, excise and other incidental costs where required.
• Allow additional lead time for urgent, perishable, pharmaceutical, regulated, postal or parcel movements.
• Keep a complete audit trail of declarations, customs messages, transport documents, system errors and any corrective or contingency action taken.
• Assess whether dedicated customs, inventory or record-keeping software is appropriate, particularly where import volumes, consolidated movements or documentary requirements are substantial; relevant business software and IT services can be identified through Gibraltar.com.

How Commercial Goods Move Under the New Arrangements

EU goods generally move to a designated customs post under a T2 transit procedure. After the relevant formalities are completed, a T2GI movement is opened for the journey to Gibraltar. HM Customs closes the T2GI movement on arrival and collects Gibraltar Transaction Tax and any applicable excise duty where the goods are being placed on the Gibraltar market.

Non-EU goods generally use T1 and T1GI procedures. Applicable EU customs duty is dealt with at the designated customs post, while HM Customs deals with the Gibraltar element of the import. Additional product-compliance, sanitary or regulatory controls may apply according to the goods and their origin.

For the full legal and procedural framework, read the Gibraltar.com guides and the official HM Government, HM Customs and Spanish customs technical guidance listed at the end of this page. Related commercial guidance is also available through the Doing Business in Gibraltar hub.

Transaction Tax and Pricing

The standard Transaction Tax rate is 15% during the first Treaty year, with reduced, zero and exempt treatment applying to qualifying goods. The tax is based on the relevant customs value rather than the retail selling price. Customs value can include duties, excise and incidental expenses such as transport, insurance, commission and packing.

Businesses should therefore calculate landed cost product by product. Applying a flat 15% increase to the retail price does not accurately reflect how Transaction Tax operates. Where classification, valuation or tax treatment is uncertain, specialist advice should be obtained before pricing or dispatch.

What Has Not Changed

• Commercial goods remain subject to formal customs procedures; frontier fluidity does not turn business imports into personal shopping.
• ASYCUDA remains the declaration system used by HM Customs Gibraltar, and no continuing Gibraltar-side outage has been officially announced.
• The standard first-year Transaction Tax rate remains 15%, subject to the correct reduced, zero or exempt treatment.
• UK-origin goods may qualify for zero customs tariff treatment only where the applicable rules of origin are met and evidenced.
• Goods merely dispatched from the UK are not automatically UK-origin goods.
• Businesses should continue to follow current official guidance and obtain professional advice where the legal, customs or tax position is uncertain.

Known Issues and Questions Still to Resolve

• What normal Commercial Gate processing times and daily throughput will look like once the initial adjustment period has passed.
• How delayed or rejected transit movements will be escalated and corrected in practice, including the use of the new La Línea and Algeciras contingency plans.
• Whether further written post-implementation guidance will address the problems, new validations and duplicate data requirements identified during the opening period.
• How groupage consignments can be processed more efficiently while meeting the consolidator, house-consignment and net-mass requirements.
• What additional sector-specific procedures will apply to pharmaceuticals, food, refrigerated goods, postal items and other regulated or time-sensitive movements.
• What continuing support and training will be provided to customs agents, freight operators and businesses using ASYCUDA or working with Spanish NCTS6 procedures.
• The date and agenda of the next Business Transition Advisory Group meeting.

What to Watch Before the Next Weekly Review

• Commercial Gate queue levels, daily throughput and the time taken to clear individual commercial consignments.
• Any new HM Government, HM Customs or Spanish Tax Agency technical notice, FAQ or operational instruction.
• Further guidance on transit procedures, groupage movements, consolidator data, guarantees, NIF/EORI, ASYCUDA or NCTS6.
• Any recurrence of problems affecting pharmaceuticals, food, refrigerated goods, post or other time-sensitive movements.
• Announcements concerning the next Business Transition Advisory Group or business Town Hall meeting.
• Evidence that the initial workarounds, system corrections and contingency arrangements have become stable, documented procedures.

Frequently Asked Questions

Is the Commercial Gate open?

Yes. It remains operational. Freight delays began to ease by Friday 24 July, but movement has not yet returned consistently to the reported pre-Treaty level and no official normal-processing benchmark has been published.

Is ASYCUDA working?

ASYCUDA remains the HM Customs Gibraltar declaration system, and no continuing Gibraltar-side outage has been officially announced. Separate Spanish NCTS6 validations and contingency arrangements have been updated for movements connected with Gibraltar.

Why have deliveries been delayed?

Reported causes include unfamiliar procedures, transitional and new-system goods being processed at the same time, missing or incorrect codes, inconsistent data, groupage complexity, duplicate system entry and coordination problems across the Gibraltar and Spanish customs chain.

Do goods ordered before 15 July automatically qualify for transitional treatment?

No. The relevant transitional treatment depends on the applicable rule and supporting evidence. For movement-based treatment, businesses need evidence that transport or shipment began before implementation, not simply an earlier order or payment date.

Are goods dispatched from the UK automatically UK-origin goods?

No. Dispatch and legal origin are different. Any preferential origin claim must satisfy the applicable rules and be supported by evidence.

Does every importer need its own Spanish NIF and EU EORI?

Not necessarily. Official guidance states that a Gibraltar business may not need its own NIF/EORI where a customs agent completes the formalities and pays the relevant taxes and duties from the agent’s own account. The arrangement should be confirmed before dispatch.

What is the standard Transaction Tax rate?

The standard rate is 15% during the first Treaty year. Reduced, zero and exempt treatment applies to qualifying goods.

When is the next Business Transition Advisory Group meeting?

The Government has indicated that a further meeting will be arranged in the coming weeks. No specific date has been published as at 27 July 2026.
