UK Plant Trade Reaches £20.4bn as Biosecurity Checks Expand Across Imports
The UK’s international trade in plants and plant commodities climbed to £20.4bn in 2025, with a net mass of 23,832 thousand tonnes. Both measures moved upward over the five-year period covered by the release, rising 29.3% in value and 10.8% in mass since 2021. The scale matters because plant trade is not just an agricultural and commercial story; it is also a biosecurity issue, since live plants, seeds, timber, soil, fruit, vegetables, and grain can carry pests and disease into new environments.
Imports drove most of the increase. Across the full period, export value and export mass also rose, but the pace was faster on the import side. In 2025, exports represented only 7.7% of total trade value, yet they accounted for 12.6% of total net mass. In practical terms, the UK ships out a comparatively larger share of physical volume than financial value, while paying more in value for incoming plant goods than it receives from outbound trade. That pattern points to a commodity mix in which higher-value products are being brought into the country, while heavier goods account for a larger share of outbound tonnage.
EU Trade Dominates Both Value and Volume
Trade with the EU remained the dominant channel in 2025. The bloc accounted for 56% of total trade value in plants and plant commodities and 62% of overall net mass. Those figures are not surprising given the proximity of markets and the deeply integrated supply chains that link UK producers, distributors, and processors with European partners. They also explain why policy changes affecting border procedures can quickly alter the number of consignments moving through plant health systems.
The five-year trend also reflects a system adapting to post-Brexit trade rules and the staged introduction of controls. The release links shifts in the notification data to the phasing in of plant health controls and easements on imports from the EU. In other words, the flow of goods did not simply rise or fall on commercial demand alone; it moved in step with regulatory timing, inspection requirements, and temporary relaxations applied to certain imports.
A shipment can look routine on paper and still carry a hidden biological risk.
PHSI Notifications Rise, Then Ease Back From Earlier Peaks
The Plant Health and Seeds Inspectorate recorded 355,324 consignments notified in 2025, up from 274,158 in 2024. Even with that rise, the 2025 total remained below the notifications seen in 2023 and 2022. The trajectory suggests a system that has not moved in a straight line but instead has been shaped by regulatory transition, importer adjustment, and the selective easing of controls on some EU goods.
These notification counts are central to how plant health authorities allocate inspection effort. A higher volume of controlled consignments means more declarations to assess, more opportunity to intercept material of concern, and more administrative burden on traders and inspectors alike. The release does not use the data to infer the effectiveness of the inspectorate, and it does not attempt to compare the three datasets directly. It does, however, make clear that the numbers are informative for understanding the flow of goods that enter the inspection pipeline.
For plant health authorities, the key issue is not just how much is traded, but what kind of material is moving and how often it must be declared for checks. Controlled commodities include plants, trees, seeds, organic matter such as soil, and specific plant products including fruit, potatoes, vegetables, cut flowers, timber, foliage, and grain. These categories are biologically relevant because each can act as a pathway for pests or pathogens, especially when traded at scale across borders.
Forestry Notifications Show Diverging Movements in Softwood and Hardwood
The Forestry Commission data cover 2021/22 to 2025/26, and in 2025/26 just over 3,400 consignments of controlled material were notified. Within that series, the movement was uneven. Softwood consignments fell by 61.3% across the period, while hardwood consignments rose by 19.2%. The split suggests changing patterns in forest product trade rather than a uniform contraction or expansion.
Those changes matter because timber is not a single risk category. Softwood and hardwood can differ in origin, processing, end use, and inspection profile, and the movement of controlled timber material remains relevant to plant health surveillance. Even modest shifts in volume can influence inspection workloads, documentary checks, and the attention given to specific commodity pathways.
The forest products figures also sit alongside the wider plant trade data to show how biosecurity regulation operates across several commodity streams at once. Live plants and food crops may attract one set of controls, while timber and related materials trigger another. The publication keeps those streams distinct, which is essential because their datasets are compiled differently and are not directly comparable.
Biosecurity Policy Depends on Trade Data, Not Just Border Controls
The release frames its purpose clearly: it is designed to improve understanding of trade patterns and support discussion and decision-making around biosecurity. That is a narrower and more useful goal than trying to prove whether a specific inspectorate is effective from trade counts alone. Trade data can show where pressure is building, where volumes are shifting, and which commodities are moving through the system in greater numbers. It cannot, by itself, measure every intercepted pest, every prevented incursion, or every change in surveillance sensitivity.
Even so, the figures carry policy weight. Rising trade value, larger tonnage, and a high concentration of trade with the EU create a steady need for inspection capacity and clear rules. The more varied the commodity mix becomes, the more important it is to align controls with the biological risk attached to each product. Plants support food supply, timber supply, rural economies, biodiversity, and wellbeing, but the same global trade that expands access to these goods also enlarges the pathway for pests and disease.
The central message of the release is straightforward: UK plant trade continues to grow, controlled notifications remain substantial, and the regulatory environment still shapes the movement of consignments year to year. The unanswered operational questions sit in the quality and methodology details, especially where the three datasets differ in how they are compiled and interpreted. Without that context, the numbers can describe scale and direction, but not the full burden of biosecurity risk at the border.
