A pallet of vitamin capsules can clear the border in hours or sit in a holding bay for weeks — the difference is almost always paperwork and product compliance, not luck. If you plan to import supplements UK buyers will actually be allowed to sell, you are stepping into food law, not just customs. The moment your goods land in Great Britain, you become the legal food business operator responsible for their composition, safety and labelling. Get the rules right before you ship, and the customs side becomes the easy part.
Why “import supplements UK” means food law first
Food supplements — vitamins, minerals, botanicals, fish oils, protein powders — are treated as food in Great Britain, not as ordinary consumer goods. That means two layers of rules apply at once. First, customs: a commodity code, an import declaration, duty and import VAT. Second, and more often the deal-breaker, food law: composition limits, permitted ingredients and strict labelling. GOV.UK is blunt about responsibility — if you import supplements, you are legally accountable for every aspect of those goods, including whether their composition and labels comply with UK rules. Products sold freely abroad are not automatically legal here.
Labelling: “food supplement”, not “dietary supplement”
Any supplement placed on the GB market must meet the general food information rules retained from Regulation (EU) No 1169/2011 (FIC), plus the specific requirements in The Food Supplements (England) Regulations 2003. One detail trips up many overseas brands: the product must be labelled as a food supplement — the US-style term “dietary supplement” is not acceptable on a GB label. Nutrition and health claims are also tightly controlled; you cannot state or imply that a product prevents, treats or cures disease. In practice, many imported supplements need to be relabelled, and sometimes reformulated, before they can legally be sold.
When is the product actually a medicine?
This is the question that quietly sinks shipments. Many ingredients and claims that are routine elsewhere are treated in the UK as medicinal or as a “novel food” requiring authorisation. If a product, an ingredient or a claim crosses that line, it is no longer a food supplement at all and needs a different regulatory route entirely. GOV.UK advises contacting the Medicines and Healthcare products Regulatory Agency (MHRA) before you place a product on the market to check whether it is considered medicinal. Doing that check pre-shipment is far cheaper than discovering it after a container has arrived.
Do you need IPAFFS pre-notification?
Whether you must pre-notify through the Import of Products, Animals, Food and Feed System (IPAFFS) depends on what the supplement contains. IPAFFS notification is required for specific categories, including products of animal origin (POAO), composite products and high-risk food and feed not of animal origin (HRFNAO). A fish-oil, collagen or dairy-based supplement can fall into the animal-origin or composite category; a straightforward plant-based vitamin tablet often does not. Under the Border Target Operating Model, sanitary and phytosanitary controls became fully required from 2024, so check your product against the current category list rather than assuming. When IPAFFS applies, the importer raising the notification takes responsibility for the consignment from entry until checks are complete, and documents must be submitted electronically (PDF preferred).
Classification, duty and import VAT
Every supplement needs a correct commodity code so the right duty and VAT are applied. GOV.UK publishes specific guidance on classifying vitamins, supplements and herbal medicines, and the distinction between a food preparation and a medicinal product matters here too — it changes both the tariff treatment and the regulatory regime. Because the figures change, confirm the current duty rate and VAT treatment on GOV.UK’s Trade Tariff for your exact code rather than relying on an old quote. If your declarations and SPS notifications need to line up cleanly, it is worth getting an experienced agent to book a customs broker for the UK–Poland leg before the goods move.
Pre-import checklist
- Confirm the product is a food supplement and not a medicine or novel food — check with the MHRA if unsure.
- Check whether the supplement is animal-origin, composite or HRFNAO and therefore needs IPAFFS pre-notification.
- Verify the commodity code using GOV.UK’s classification guidance and Trade Tariff.
- Redesign the label to GB rules: marked “food supplement”, FIC-compliant, with permitted claims only.
- Confirm ingredients and dosage levels are permitted in Great Britain; plan for reformulation if not.
- Gather supporting documents (specifications, certificates) in electronic format before the goods ship.
- Brief your customs agent so the import declaration and any SPS notification match.
If you regularly bring regulated goods across the border, our earlier guide on importing cosmetics to the UK and CPNP compliance walks through a similar compliance-first mindset.
Mini-FAQ
Do I always need IPAFFS to import supplements to the UK?
No. IPAFFS pre-notification applies to specific categories such as products of animal origin, composite products and high-risk food not of animal origin. A plant-based supplement that is not high-risk often falls outside it — but you must still meet UK food law. Check your product against the current GOV.UK category list.
Must the label say “food supplement”?
Yes. Products placed on the GB market must be labelled as a food supplement (not “dietary supplement”) and comply with FIC and The Food Supplements (England) Regulations 2003.
Could my supplement be classed as a medicine?
Possibly. Some ingredients or claims are treated as medicinal or as a novel food in the UK. GOV.UK advises checking with the MHRA before you place the product on the market.
