Why Source from China — and When Not To

For context: where else can you get this

GOV.UK tells you how to import but not whether you should. Freight forwarder blogs always conclude "yes, source from China (and ship with us)." Platform guides always conclude "yes (and buy on our marketplace)." Paid consultancy reports answer this question rigorously but cost £500+ per report and target corporates. This article gives you a structured framework, grounded in HMRC trade data you can verify yourself, for free.

Three signals that justify China sourcing

These three conditions must hold simultaneously for China to be the structurally right answer. Each has a concrete test you can apply to your own product category.

Signal 1: Volume. Your annual quantity is large enough that the supplier's minimum order quantity (MOQ) and tooling amortisation work in your favour. In practice, most Chinese factories set MOQs that assume container-load economics. If your annual requirement fills at least one 20-foot container equivalent per order cycle, the volume signal passes. If you need 50 units per year and the MOQ is 500, the volume signal fails — and a trading company bridging the gap will apply their own margin on top.

Signal 2: Cost differential. The unit-cost gap between China and the nearest alternative covers freight, duty, lead-time inventory holding cost, and verification overhead — with margin to spare. This is not a simple unit-price comparison. A product that is 30% cheaper ex-works in China but attracts a 6.5% Most Favoured Nation (MFN) duty rate, approximately 4-6 weeks of ocean transit inventory cost, and £1,000+ in conformity documentation per product line may land in your warehouse at near-parity with a UK or near-shore alternative. The cost-differential test is a landed-cost question, not a unit-price question.

Signal 3: Capability. The spec, materials, or finishing you need are not economically reproducible at UK or near-shore volumes. This is the signal that most clearly separates structural advantage from simple cost arbitrage. If a UK manufacturer can produce the same product at 15% more but with a 2-week lead time, the capability signal may not pass — because the cost-differential must carry the full freight and compliance overhead. If the UK manufacturer cannot produce it at all (or not at the required volume), capability passes clearly.

Three signals that say "look elsewhere"

Signal 4: Lead-time intolerance. Shanghai to Felixstowe runs approximately 4-6 weeks ocean transit. Add pre-production time, inland transport at both ends, and customs clearance, and the total supply chain lead time is commonly 8-10 weeks from order placement. If your business cannot carry that inventory buffer — because demand is volatile, because your customer expects 2-week replenishment, because the product has a short shelf life — China is the wrong answer regardless of unit price.

Signal 5: Single-batch or low-MOQ requirement. If you need a one-off production run of 100 units with no repeat order commitment, most Chinese factories will not engage directly. Trading companies can bridge the gap but at trader pricing — which erodes the cost-differential signal. The combination of low volume and no repeat commitment makes the economics structurally unfavourable.

Signal 6: Sensitive regulated category. Products in IP-critical, controlled-export, or heavily regulated sectors (medical devices, aviation components, certain chemicals subject to UK REACH) carry documentation burdens that can stall an order entirely if the Chinese factory is not set up for them. UK REACH, which operates independently from EU REACH since 1 January 2021, requires registration for substances manufactured in or imported into Great Britain at a threshold of 1 tonne per year. For a small UK industrial order, the compliance cost per unit can be disproportionate.

The HMRC OTS lookup — confirm the trade flow exists

Before committing to any of the signals above, run one sanity check: does the trade flow actually exist for your product category?

Open uktradeinfo.com — the HMRC Overseas Trade Statistics (OTS) custom table builder. Select your Harmonised System (HS) chapter. Set the trading partner to China. Set the period to the most recent 12 months available.

Three things to note from the results:

1. Total value. If UK imports of your HS chapter from China are £0 or negligible, the trade flow does not exist at meaningful scale. That is not proof it cannot work, but it is a red flag that no established supply chain infrastructure exists for that route.

1. China's share. Compare China's import value to the total from all origins. A chapter where China supplies 25% of UK imports has a very different infrastructure base than one where China supplies 2%.

1. Top alternative origins. Note the top 3 non-China sources. If a Comprehensive and Progressive Agreement for Trans-Pacific Partnership (CPTPP) member country appears high on the list, the preferential tariff rates now available under CPTPP — effective 1 January 2026 following UK accession on 15 December 2024 — may shift the cost-differential calculation.

This lookup takes 15 minutes. It is a sanity check, not a deep analysis. The worked example in Issue #10 demonstrates the full process on a specific HS code.

The conformity-regime question

One question must be answered before the strategic decision is final: which conformity regime applies to your product in Great Britain?

The landscape here has simplified considerably since 2024. Under The Product Safety and Metrology (Amendment) Regulations 2024 (SI 2024/696, in force 1 October 2024), CE marking is now indefinitely recognised in the Great Britain market for products where product regulations meet UK needs. The UK Conformity Assessed (UKCA) marking remains available, and a Fast-Track UKCA pathway exists for products already holding CE certification. UKCA marking on labels and documentation is permitted until 31 December 2027.

The practical implication: for many industrial product categories, a Chinese factory already producing to CE standards can supply the GB market without a separate UKCA certification process. But this varies by sector. The GOV.UK "Product regulations by sector" table lists which marking regime applies to which product type. Check your specific sector before assuming CE recognition covers your product.

The conformity answer changes the documentation burden the supplier must meet — and therefore the cost-differential maths in Signal 2.

Gatekeeper view: what is visible from China-side

When a UK buyer asks "should I source from China?", the Chinese factory already has an answer — from the other side. Factories in active export categories track order intake by destination. They know whether UK demand in their HS chapter has grown, contracted, or shifted to other origins.

For categories where UK orders are growing, factories invest in export-grade production lines and English-speaking sales teams. The buyer's inquiry is welcomed.

For categories where UK orders are shrinking — or where documentation requirements (UKCA testing, UK REACH registration, labelling specifications) create overhead that exceeds the margin on a £30,000 order — some factories actively screen out smaller UK industrial inquiries. They do not decline openly. They quote slowly, set MOQs above the buyer's range, or redirect the inquiry to a trading company. That screening is invisible to the buyer browsing Alibaba.

The signal for the buyer: if multiple factories in your category are unresponsive or quote above market rates, the issue may not be your negotiation skills. It may be that the category's economics no longer favour small UK orders.

Where this framework breaks

Hybrid products spanning multiple HS chapters. A product with components from HS 84 (machinery) and HS 73 (articles of iron and steel) may produce different signal readings for each component. The decision tree gives a clear answer for single-HS products. For multi-HS assemblies, you may need split sourcing — which complicates logistics and adds coordination overhead.

Rapidly shifting tariff environments. If a trade remedy investigation is underway — anti-dumping duties, countervailing duties, safeguard measures — the cost-differential signal can flip within months. The framework gives a snapshot. It does not forecast tariff changes. Check the Trade Remedies Authority (TRA) register for active investigations in your HS chapter.

Capability that exists but is not discoverable. UK or near-shore manufacturers may have capacity the buyer cannot find through standard directories. The "capability" signal is only as good as the buyer's search. If you have not checked UK manufacturing directories (Make UK, sector trade associations, British Standards Institution listings), the signal may be unreliable.

Exchange rate volatility. The cost-differential signal is denominated in GBP/CNY. A sustained move of 5%+ can invert the economics on thin-margin products. The framework assumes a reasonably stable rate environment. If GBP/CNY has moved more than 5% in the past 6 months, stress-test Signal 2 at both the current rate and the adverse end of the recent range.

Products where the spec is still evolving. Iterative prototyping over 8,000 miles with an 8-10 week feedback loop is structurally painful. If the product design is not stable — if you expect 3+ specification revisions before production — the lead-time signal fails not because of transit time but because of communication latency.

Trends layer

As of May 2026: the UK government's indefinite extension of CE marking recognition under SI 2024/696 means the conformity-regime question is simpler than many buyers expected. Products that meet CE requirements can enter the GB market without separate UKCA certification for the foreseeable future. But this varies by sector and is subject to change on a statutory-instrument-by-statutory-instrument basis.

Separately, CPTPP preferential tariff rates are now live following UK accession. For some industrial HS chapters, the duty differential between MFN rates (applied to China) and CPTPP preferential rates is 4-8 percentage points — enough to shift the cost-differential signal from "China wins" to "borderline." The UK Trade Tariff should be checked for your specific HS code.

Coming up

Issue #10 applies this decision framework to a real HS code with real HMRC data — a worked example where the answer is not obvious. Issue #11 moves to discovery: once you have decided China is the right origin, where do you find suppliers beyond Alibaba?
