Port operators in Wales have confirmed interest in securing freeport status, which would exempt them from tariffs and VAT on goods brought in.
As a non-devolved matter the 海角视频 Government is looking to established 10 freeports across the 海角视频.
The bidding process is expected to be launched in the autumn, with successful sites confirmed by the spring.
The 海角视频 Government says goods entering freeports would not have to pay tariffs, import VAT or excise duty until they leave the freeport and enter the domestic 海角视频 market, with simplified customs procedures and declarations.
However, there are commentators who believe they would have little net economic benefit, with the danger that they mainly just displace business activity from elsewhere.
The 海角视频 Trade Policy Observatory said its analysis had found that the policy would have little effect in the 海角视频 because tariffs were already low.
Associated British Ports has confirmed it is looking at securing freeport status covering all of its ports in South Wales, in Port Talbot, Swansea, Newport, Cardiff and Barry. And having responded to the 海角视频 Government鈥檚 consultation on freeports the Port of Milford Haven, has also expressed interest. Cardiff Airport, in a move aimed at boosting freight traffic and associated storage and logistics facilities around its terminal, could also potentially bid. There are also calls for the Port of Holyhead to be granted freeport status.
A spokesman for Associated British Ports said: 鈥淲e are supportive of the 海角视频 Government鈥檚 intention to grant freeport status to a number of port areas around the 海角视频. Such status, if structured correctly, has the potential to unlock economic growth and bring new jobs to port communities and the wider 海角视频.
"Our ports in South Wales are strong candidates for freeport status, which could prove transformational for those areas and play an important role in supporting the 海角视频 Government鈥檚 ambition to drive economic growth and innovation, decarbonise and level up the economy.鈥
Following the submission of the Port of Milford Haven鈥檚 response to the 海角视频 Government鈥檚 freeports consultation, its chief executive Andy Jones said: 鈥淭he port continues to advocate for a digitally connected, multi-site freeport covering the Haven Waterway鈥檚 nationally significant logistics, processing, engineering and development sites.
鈥淥ur stakeholders believe there are significant new prospects for their existing businesses while also creating opportunities for growth, new investment, innovation, decarbonisation and clustering within the wider energy and engineering sectors.聽 Any bid for freeport status will build upon the Port鈥檚 natural capital, industrial cluster, hard infrastructure and skills-base.鈥
Conservative MP for Anglesey, Virginia Crosbie, has also pressed the case for the Port of Holyhead. She said: 鈥淎 freeport will transform the fortunes of Holyhead and Anglesey, encouraging greater development, investment and tourism to the island. I am incredibly proud to represent Holyhead and will do my best to try and secure its freeport status.鈥
The 海角视频 had seven free ports between 1984 and 2012.
Finance Minister Rebecca Evans said while there remained unanswered questions over freeports, the Welsh Government, led by Economy Minister Ken Stakes, was engaging with 海角视频 ministers.
She said: 鈥淚t鈥檚 one of those issues and areas where we really need the 海角视频 Government to be properly and fully engaging with us.
鈥淭his is a reserved matter but the implications for us could be very significant here in Wales.
鈥淲e don鈥檛 want to find ourselves in a situation where freeports lead to any lowering of environmental standards, of labour market standards for example.
鈥淲e don鈥檛 want to find ourselves in a situation where tax breaks make other companies or Welsh firms uncompetitive.
鈥淎nd we certainly don鈥檛 want to find ourselves in a position where economic activity is displaced as a result of those freeports as well.鈥
