Key Takeaways
- The £135 low value import duty relief has not ended yet, but GOV.UK says it will be removed by October 2028 at the latest.
- The reform is about customs duty and customs processes, not the 2021 change that moved VAT collection for many low-value ecommerce orders to the point of sale.
- GOV.UK’s consultation says BIRDS handled about 600 million low value import consignments in 2024, so even small per-parcel cost changes can reshape fulfilment decisions.
- Local UK fulfilment is not a legal requirement, but it may become commercially stronger for repeat SKUs, predictable UK demand, high-return products, and non-zero duty categories.
- Sellers need item-level SKU data, commodity codes, origin evidence, VAT treatment, marketplace liability mapping, and fiscal-representative assumptions before choosing a network model.
The short answer
The end of £135 customs duty relief turns a once-simple ecommerce shortcut into a landed-cost decision. GOV.UK says low value imports are individual consignments from outside the UK to UK recipients with a declared value of £135 or less, and that those consignments currently receive full customs duty relief. The government now intends to remove that relief by October 2028 at the latest, according to its 23 June 2026 announcement and the tax information note published on 13 July 2026.
That does not mean every overseas seller must move inventory into a UK warehouse. It means the current direct-to-consumer parcel model needs to be tested against a bulk-import and local-fulfilment model using real duty rates, real return flows, and real compliance costs. For some merchants, direct parcel fulfilment will still win because UK demand is uncertain, duty rates are low or zero, or storage creates more risk than it removes. For others, UK stockholding will become the cleaner way to control margin, delivery promise, returns, and customs evidence.
The reform also changes who carries operational responsibility. GOV.UK says sellers and online marketplaces, where they facilitate the sale, will be responsible for paying customs duty on low value imports to HMRC. The consultation indicates that duty payment is intended to happen quarterly after goods enter the UK, and that non-UK sellers or marketplaces without a physical UK presence may need a UK-based fiscal representative with joint and several liability.
The practical question is therefore not “Do we need a UK warehouse?” It is “At what SKU volume, duty rate, return rate, and compliance cost does UK fulfilment beat cross-border parcel injection?” Sellers should start that modelling before the final regulations land.
What the £135 relief currently does
The £135 threshold applies to customs duty on low value imports, not to whether the sale is visible for VAT. HMRC’s marketplace guidance says the £135 limit applies to the total consignment value, not the value of each separate item inside the package. A basket of four £40 items is not four separate low-value items for this purpose if they travel as one £160 consignment.
For many overseas-to-GB ecommerce sales, VAT is already dealt with at the point of sale. HMRC says online marketplaces are liable for VAT on consignments of £135 or less sold through a marketplace to GB customers. HMRC also says marketplaces can be liable for VAT on goods of any value that are located in the UK at the point of sale and sold by an overseas business through that marketplace.
That distinction matters because the 2026 reform is not a repeat of the 2021 removal of Low Value Consignment Relief for import VAT on goods valued at £15 or less. The remaining £135 rule is a customs duty relief for low value imports. When it is removed, the VAT logic, customs duty logic, and import process all need to be mapped separately.
The current relief also supports a specific fulfilment habit: keeping stock offshore, selling to UK consumers online, and injecting many small parcels into the UK. If those parcels stay at or below £135, the duty component is relieved, even though VAT may be charged through the sales channel.
What the government is changing
GOV.UK’s July 2026 consultation says the government intends to remove the £135 duty relief and make low value imports subject to customs duty. The June 2026 news release accelerated the latest implementation date to October 2028, six months earlier than the original March 2029 outer date. The tax information note says the change will be brought in by Treasury regulations made by statutory instrument.
The volume affected is large enough to change behaviour. HMRC sample analysis cited in the consultation estimates that low value import consignments imported using BIRDS were about 600 million in 2024, around 1.6 million per day. GOV.UK also says BIRDS volumes more than tripled between calendar year 2021 and the annual period ending June 2024.
The value trend points the same way. GOV.UK says total trade value declared within BIRDS increased by over 50%, from £3.8 billion in 2023-24 to £5.9 billion in 2024-25, while noting that the true value is likely higher. Those figures explain why a change framed as a customs relief reform is also a fulfilment network issue.
The process will not simply be “pay a bit more at the border”. GOV.UK says BIRDS currently allows one reduced-dataset declaration to cover many low value imports, but HMRC will need item-level data once the relief is removed. That points to more pressure on SKU master data, commodity codes, country-of-origin records, valuation controls, and marketplace transaction matching.
Why local fulfilment moves up the agenda
Local fulfilment becomes more attractive when duty, data, cash flow, and customer promise are easier to control through bulk import than through parcel-by-parcel movement. A bulk import model lets the seller classify goods, value shipments, handle duty accounting, and move stock into a UK warehouse before customer orders are picked. It can also support faster delivery, simpler returns, and fewer surprises for customer service teams.
That does not automatically make it cheaper. UK stockholding adds warehousing cost, inbound freight planning, stock risk, shrinkage controls, UK returns processing, and potentially marketplace VAT responsibilities depending on the selling model. The right comparison is not parcel freight versus warehouse rent; it is total landed cost, service level, working capital, compliance exposure, and return recovery.
The first modelling step is classification. Every SKU needs a commodity code before a seller can compare direct parcel import with bulk UK stock, so teams should review the basics in a commodity code classification guide before building the cost model. A workflow tool such as TariffFlow can help structure that classification work and keep an audit trail, but the important operational point is the same: the fulfilment answer is only as good as the duty-rate data behind it.
The second step is order profile. Products with regular UK demand, stable SKUs, repeat customers, and predictable reorder cycles are easier to hold locally. Long-tail test products, uncertain seasonal lines, and low-volume specialist goods may still justify cross-border parcel fulfilment because the cost of wrong UK stock is higher than the incremental duty and process cost.
When UK stockholding may make sense
UK fulfilment is strongest when the seller can turn stock quickly and use the warehouse to improve both margin control and customer experience. Repeat SKUs with steady UK demand are the clearest candidates. If you can forecast weekly order volume with confidence, you can compare container, pallet, or carton-level imports against individual parcel clearance with a reasonable cost base.
Products with non-zero duty rates need early attention. A seller importing goods under a 0% duty classification may see less change from the removal of the relief than a seller with a 6%, 10%, or 12% product category. The model also needs to include VAT-on-duty effects where duty increases the taxable import value.
High-return categories are another strong candidate. Fashion, footwear, consumer electronics accessories, and trial-led products can become expensive when every return crosses a border or needs offshore handling. Local returns can support inspection, refurbishment, resale, consolidation, or disposal inside the UK, rather than creating a second international movement.
Marketplace-heavy sellers should also model local fulfilment carefully. HMRC’s guidance already treats online marketplaces as VAT liable in specific cases, including goods located in the UK at the point of sale and sold by an overseas business through a marketplace. That does not mean UK stock is wrong, but it means tax, marketplace, and fulfilment teams need one shared operating model rather than separate assumptions.
Finally, overseas sellers that may need a UK fiscal representative should test whether local stock makes the compliance relationship easier to manage. GOV.UK says the government is considering a requirement for non-UK sellers and marketplaces without a physical UK presence to appoint a UK-based fiscal representative. If that person or business carries joint and several liability, they will care deeply about the seller’s customs data quality.
When direct parcel fulfilment may still work
Direct cross-border fulfilment can still make sense where UK demand is small, uncertain, or highly fragmented. A seller with thousands of slow-moving SKUs may prefer to hold inventory in one regional hub and accept more customs process per parcel rather than duplicate stock across markets. That can be rational if the customer promise, cost, and compliance controls remain workable after the relief ends.
Zero-duty products also need a sober view. If a SKU is correctly classified at 0% duty, removing the relief may not add a customs duty charge, although it can still add process, data, and representative cost. The decision then turns on operational friction rather than tariff cost alone.
Seasonal goods can be harder to localise. If demand spikes around a short campaign, a seller can easily over-import into UK stock and then hold stranded inventory after the season ends. In those cases, direct parcel fulfilment may remain the better test-and-learn model until demand is proven.
Products with storage, safety, licensing, or compliance constraints may also resist a simple UK-warehouse answer. Batteries, cosmetics, food-contact items, medical products, and controlled goods can require additional checks beyond ordinary fulfilment capability. For those categories, UK stockholding should be compared with import licence and product compliance obligations, not assessed as a pure delivery-speed decision.
Build the landed-cost model
Start with the SKU file, not the warehouse quote. Each product needs a commodity code, country of origin, customs value method, duty rate, import VAT treatment, product restrictions, and evidence owner. If the classification is uncertain, fix that first using the UK Trade Tariff, a customs adviser, or a structured classification workflow, then test the numbers against a full UK import duty calculation.
Then split orders by route. Model seller-direct website orders separately from marketplace-facilitated orders because tax and data responsibilities can differ. Split consignments at or below £135 from higher-value orders, then estimate how the mix changes once the duty relief disappears and what the customs clearance process will need from each channel.
Next, compare duty and process cost under two operating models. For direct parcel fulfilment, include parcel freight, customs data capture, quarterly duty settlement assumptions, fiscal-representative cost if relevant, customer-service contacts, failed deliveries, and returns. For UK fulfilment, include bulk inbound freight, customs clearance, duty and VAT timing, warehouse receiving, storage, pick and pack, domestic parcel cost, returns handling, and inventory write-off risk.
The model also needs a cash-flow view. GOV.UK says the government intends duty payment by sellers and facilitating marketplaces to be made quarterly after goods enter the UK. That may be helpful for some direct parcel flows, but it does not remove the need to accrue landed cost accurately at SKU and order level. If finance only sees the duty bill later, merchandising can make margin decisions with stale data.
Finally, stress-test the answer. Increase duty rates where classification is uncertain, reduce demand forecasts, raise return rates, add a fiscal-representative fee, and test a customs-data correction scenario. A fulfilment model that only works under perfect assumptions is not ready for the post-relief environment.
Operational checklist for sellers and 3PLs
Sellers should begin with a customs data audit. Confirm that every UK-selling SKU has a commodity code, origin, product description, unit value, and supplier evidence. If a product cannot be classified confidently, do not wait until the first post-reform duty bill to resolve it.
3PLs should ask different questions in sales conversations. The old brief of order volume, storage footprint, and pick profile is no longer enough for overseas ecommerce sellers. The fulfilment provider needs to understand whether the customer is moving from cross-border parcel injection, whether duty rates are material, and whether returns or marketplace rules are driving the warehouse decision.
Finance teams should build a margin bridge. Show current margin under direct parcel fulfilment, then add duty, data, representative, and process cost. Compare that with local fulfilment including warehouse cost, domestic delivery, working capital, and returns recovery. The winning option may vary by SKU family rather than across the whole catalogue.
Marketplace teams should review terms and data feeds. If a marketplace facilitates the sale, GOV.UK’s proposed model may place duty responsibility on that marketplace, but sellers still need product data that supports the transaction. Poor commodity descriptions, missing origin, and inconsistent SKU records can create chargebacks, blocked listings, or compliance escalations even where the marketplace is the formal collector.
The decision is whether the end of the £135 duty relief makes the current flow less resilient than a UK stock model. For many ecommerce businesses, the answer will be mixed: local fulfilment for proven UK winners, direct cross-border fulfilment for test SKUs, and tighter classification governance across both.
Frequently Asked Questions
Has the £135 duty relief already ended?
No. GOV.UK says the relief is scheduled to be removed by October 2028 at the latest. The current planning task is to prepare for the change, not to treat it as already in force.
Is this the same as the 2021 VAT change?
No. The 2021 change removed Low Value Consignment Relief for import VAT on goods valued at £15 or less and shifted VAT collection for many low-value ecommerce orders. The 2026 reform concerns the £135 customs duty relief and the customs treatment of low value imports.
Does every overseas seller need a UK warehouse?
No. Local fulfilment is a commercial option, not a statutory requirement. It may suit predictable UK demand, high-return categories, and products with meaningful duty rates, while direct parcel fulfilment may still suit low-volume, seasonal, or zero-duty goods.
Why does commodity classification matter so much?
The commodity code determines the duty rate, trade measures, and sometimes restrictions. Without accurate classification, a seller cannot compare a direct parcel model with a UK stockholding model because the duty line in the landed-cost model is unreliable.
What should 3PLs do before pitching local fulfilment?
Ask for SKU-level data, order mix, return rates, marketplace channels, country-of-origin evidence, and likely duty rates. A credible local-fulfilment proposal should compare total landed cost and compliance control, not just quote storage and pick fees.
