Manufacturer imports steel from EU for £100/ton pre-Brexit (no tariff). Post-Brexit: £115/ton (15% tariff). Annual import: 1,000 tons = £15K additional cost. On 15% margin product, that's a 30% margin hit. AskBiz tracks tariff cost, identifies cheaper UK suppliers or alternative materials.

Post-Brexit Tariff Impact#
UK-EU trade now subject to tariffs (previously zero). Tariff rates vary: steel 15%, chemicals 5-10%, textiles 10-20%. For manufacturers, this increases COGS significantly.
Re-Shoring Decision#
Some manufacturers sourcing from EU pre-Brexit switched to UK suppliers post-Brexit to avoid tariffs. Cost trade-off: UK supplier might be 5% more expensive but 0% tariff vs. EU supplier 5% cheaper but 15% tariff = net 10% cost advantage for UK.
AskBiz Tariff & Sourcing Analysis#
AskBiz tracks: (1) Current supplier cost + tariff. (2) Alternative UK supplier cost (no tariff). (3) Financial impact of switching. "Your EU steel costs: £100 + £15 tariff = £115/ton. UK supplier: £110/ton (no tariff). Switch saves £5/ton. 1,000 tons/year = £5K savings."
Why the Commodity Code You Use Changes What You Owe#
Every imported component is classified under a commodity code, sometimes called an HS code, which determines the exact tariff rate that applies to it. These codes run to ten digits and are organised by material, function, and level of processing, which means two components that look almost identical to a factory owner — say, a machined steel bracket versus a similar bracket that has also been powder-coated — can sit under different codes with different duty rates. Manufacturers who are not customs specialists often default to whatever code their freight forwarder or the previous shipment used, without checking whether it is actually correct for the specific item. This matters in both directions: using a code with a higher duty rate than necessary means overpaying on every shipment indefinitely, while using an artificially low code, even by accident, creates a compliance exposure that can surface years later in an audit, complete with backdated duty demands and interest across every affected shipment. A small precision-parts manufacturer in the Midlands discovered during a supplier review that a batch of aluminium housings had been imported under a generic "other metal articles" code for two years, carrying a materially higher duty rate than the correct, more specific code for machined aluminium components would have carried. Correcting the classification going forward, and reclaiming duty on shipments still within the time limit for amendment, recovered a meaningful five-figure sum. Getting the code right once, and keeping a documented justification for why that code applies to that specific product, is one of the highest-leverage single actions a manufacturer can take on landed cost.
The Bill After the Tariff: A Furniture Maker's First European Shipment#
A small bespoke furniture manufacturer in Yorkshire, sourcing cabinet hinges and drawer runners from a supplier in Poland, priced their first post-Brexit order using the supplier's quoted unit price plus the published tariff percentage for that hardware category, and budgeted accordingly. When the shipment actually cleared customs, the total landed cost came in noticeably higher than the budget, and the owner spent an afternoon on the phone with the freight forwarder trying to understand why. The gap turned out to be a combination of three separate charges layered on top of the tariff itself: a customs clearance fee charged by the forwarder for handling the import declaration, a disbursement fee for the forwarder fronting the VAT and duty payment on the manufacturer's behalf before recharging it, and a short delay at the port that triggered a demurrage charge because the paperwork had a minor discrepancy between the commercial invoice value and the declared customs value. None of these charges are unusual or improper — they are simply the standard mechanics of importing that nobody had walked the owner through before the first shipment. After that first order, the furniture maker began asking every EU supplier for a landed-cost estimate that separated product price, freight, tariff, and broker fees as distinct line items, which turned a recurring unpleasant surprise into a predictable, budgetable cost.
Duty Deferment and Postponed VAT Accounting: Two Cash-Flow Tools Worth Knowing#
Two mechanisms exist specifically to ease the cash-flow pressure that customs duty and import VAT can place on a regularly-importing manufacturer, and both are worth understanding even in outline. A duty deferment account allows an importer to delay paying customs duty on a shipment until a set point later in the month, rather than paying it immediately at the point of clearance, which smooths out cash flow for a business that imports frequently rather than forcing a duty payment to coincide awkwardly with every individual shipment's arrival. Postponed VAT accounting, separately, allows an importer to account for import VAT on their normal VAT return rather than paying it upfront at the border and waiting to reclaim it — which for a VAT-registered manufacturer removes a cash-flow gap that can otherwise tie up working capital for weeks between paying VAT at customs and recovering it via the VAT return cycle. Neither mechanism reduces the actual amount of duty or VAT owed; they simply change the timing of when it is paid, which is precisely the point for a manufacturer whose margin is sound on paper but whose cash flow is stretched thin by shipment timing. A manufacturer bringing in regular container loads of components who is still paying import VAT at the border in full, rather than using postponed accounting, is often needlessly starving their own working capital for no compliance benefit whatsoever.
The Hidden Costs That Never Show Up in the Tariff Percentage#
A manufacturer comparing an EU supplier against a UK alternative purely on tariff percentage is comparing an incomplete picture, because the tariff is rarely the largest hidden cost in the transaction. Customs broker or forwarder fees apply per shipment regardless of value, which disproportionately penalises manufacturers who order smaller, more frequent batches rather than consolidating into larger, less frequent shipments. Paperwork errors — a mismatched commodity code, an incorrect country-of-origin declaration, a missing certificate for a regulated material — can result in a shipment being held at the port for inspection, which creates both a direct demurrage cost and an indirect cost in production delay if that shipment was feeding an active production schedule. Currency fluctuation between order and payment date adds a further variable that a pure tariff comparison ignores entirely. When all of these are added together, the effective cost premium of an EU import over a UK-sourced equivalent is frequently higher than the headline tariff percentage alone would suggest, sometimes meaningfully so for manufacturers who order in small, frequent batches. This is exactly why sourcing decisions need to be made on true all-in landed cost per unit rather than on a supplier's quoted unit price with an estimated tariff bolted on afterwards.
Seeing the True Cost Per Unit with AskBiz#
The core difficulty every importing manufacturer faces is that the real cost of a component is scattered across several separate documents — the supplier invoice, the customs declaration, the freight invoice, and the broker's fee note — and by the time all of them arrive, nobody goes back and recalculates what that specific batch of components actually cost per unit. AskBiz addresses this by letting a manufacturer track supplier costs alongside landed-cost components for each purchase, so that duty, freight, and broker fees can be recorded against the specific stock they relate to rather than absorbed as a vague overhead line at the end of the month. Over time, this builds a true all-in cost per unit for each component and each supplier, which is the only number that actually supports a reliable re-shoring or re-sourcing decision — a UK supplier quoting a higher unit price can still be cheaper once the EU alternative's duty, broker fees, and delay risk are factored in, and a manufacturer working from headline material price alone has no way of knowing that until the comparison is made properly. For manufacturers running their books through Xero, AskBiz keeps this cost data aligned with the accounting records, so the true landed cost feeding into pricing and margin decisions matches what actually shows up in the company's financial statements, rather than two systems quietly telling two different stories.
