Commodity Codes, HS Codes and EORI Explained

A consignment can be perfectly made, properly packed and wanted by an overseas customer, yet still be stopped because one number is wrong. Commodity codes, HS codes and EORI details may sound like customs administration, but they sit at the point where a commercial sale becomes an international movement of goods. Get them right and the shipment has a sound basis for customs clearance. Get them wrong and an exporter may face delays, extra duty, penalties or an awkward conversation with a customer who expected delivery.

This is not a subject best left until the goods are on the lorry. In practical export work, classification and customs identification should be settled while a quotation is being prepared. They affect duty, import restrictions, documents, landed cost and sometimes whether a market is commercially worthwhile at all.

Commodity codes, HS codes and EORI: three different jobs

The terms are often used together, which encourages the impression that they are interchangeable. They are not. A commodity code describes the goods for customs purposes. An HS code is the internationally recognised foundation of that description. An EORI number identifies the business or person dealing with customs.

The HS, or Harmonised System, is an international nomenclature administered through international customs arrangements. Its first six digits are used widely across the world. A British-made steel fitting and a similar fitting leaving another country should begin from the same international classification logic, although national tariff systems can add further detail.

In Great Britain, imports and exports normally require a more detailed commodity code, commonly ten digits. The first six digits are the HS heading and subheading; later digits reflect the UK tariff treatment. Those additional digits may determine the applicable duty rate, a quota, an anti-dumping measure, a licence requirement or a statistical distinction. Calling the whole ten-digit number an ‘HS code’ is commonplace, but it can conceal the difference between global classification and the UK’s more specific customs tariff.

An EORI, or Economic Operators Registration and Identification number, has a wholly different purpose. It is the customs identity of the trader. A UK business generally uses a GB EORI number for customs activity involving Great Britain. Businesses moving goods involving Northern Ireland may need an XI EORI in relevant circumstances, reflecting the distinct arrangements that have applied since the UK left the EU customs framework.

One number answers ‘what are the goods?’ The other answers ‘who is the customs trader?’ Both must be consistent across the declaration, commercial invoice, transport paperwork and the records held by the exporter and importer.

Why a plausible description is not enough

Years ago, many smaller exporters treated the invoice description as the essential customs document. ‘Machine parts’, ‘electrical equipment’ or ‘samples’ might have appeared sufficient. They were never very satisfactory descriptions, and in a more data-driven customs environment they are plainly inadequate.

A commodity code follows rules, not intuition. Classification is generally based on the product as presented at the border: its material, function, construction, degree of manufacture and sometimes its intended use. A component may be classified as a part, as a general-purpose article, or as a complete item if it has the essential character of that item. The answer can turn on a small but material detail.

Consider a business exporting an electrically heated industrial cabinet. Is it principally heating equipment, a piece of laboratory apparatus, an item of furniture or part of a production line? The sales catalogue may call it a cabinet. Customs classification requires a more disciplined answer. The technical specification, photographs, operating method and intended function matter far more than the marketing name.

This is where experience is valuable. The right question is rarely, ‘What does our customer call it?’ It is, ‘What is it, objectively, when tested against the tariff structure and its legal notes?’ Those notes are not light reading, but they exist because similar-looking products can have quite different customs treatment.

The commercial consequences of getting it wrong

The immediate concern is often customs delay. That is real enough, particularly where a declaration is selected for checking. But the longer-term consequences can be more serious. A wrong code may mean that too little duty has been paid. Customs can seek the unpaid amount later, potentially with interest or penalties. If too much duty has been paid, the importer may have lost money unnecessarily and will not thank the exporter for an avoidable error.

Classification can also affect eligibility for preferential tariff treatment under a trade agreement. Preference is not simply a matter of stating that goods were made in Britain. Origin rules must be met and evidenced, and the correct commodity classification is often central to deciding which origin rule applies. Classification and origin are separate disciplines, but they meet on the same customs declaration.

Then there are controls beyond duty. Some goods are subject to licensing, safety requirements, sanctions restrictions, product-specific controls or anti-dumping duties. An inaccurate code does not make such obligations disappear. It merely increases the chance that they will be discovered late, after costs have been incurred and commitments made.

For a small exporter, this can alter the economics of a sale. A low-margin order may look attractive until freight, customs agent charges, duty and a delayed payment are considered. International trade rewards careful preparation rather more reliably than optimism.

A sensible method for classifying goods

Begin with the product, not a search box. Assemble a short technical file containing a precise description, composition, dimensions, function, photographs, drawings where useful, and details of how the product is supplied. If it is a machine or electronic item, include the operating principle. If it is a textile, food, chemical or composite article, the material information becomes especially important.

Next, work through the tariff from its sections and chapters towards the relevant headings and subheadings. Keyword searches can be helpful, but they are only a starting point. Search results may offer several apparently reasonable answers. The legal chapter notes, section notes and explanatory material decide between them.

Check whether the proposed code brings an unexpected duty rate, control or description. An unexpected result is not proof that the code is wrong, but it is a reason to revisit the reasoning. A product’s classification should be capable of being explained calmly to a customs officer, a customer and a finance director.

For routine, low-risk goods, an experienced customs intermediary may assist. For high-value, technically unusual or repeatedly exported products, it can be worth seeking an Advanced Tariff Ruling from HM Revenue and Customs. That gives greater certainty than relying on a hurried judgement or on a code copied from an old invoice. It is particularly sensible where the difference in duty is substantial or a classification dispute could disrupt a regular market.

Keep a classification record. Note the code selected, the evidence considered, the date of review and the reasoning. Product designs change. Tariff codes change. A classification made five years ago may not remain sound merely because it has been used without challenge.

EORI is simple, but responsibility is not

Obtaining an EORI number is generally more straightforward than determining a difficult commodity code. The complications arise when businesses are unclear about who is acting in whose name. Exporter, importer, declarant, customs agent, carrier and consignee may all appear on the paperwork, but their roles are not identical.

A freight forwarder or customs agent can prepare a declaration, yet the trader should not assume that responsibility has been entirely transferred. The exporter must provide accurate commercial information, including the correct goods description, value, origin where relevant, Incoterms and commodity code. An agent cannot reliably repair information that was vague or wrong at source.

The EORI used must also match the party’s customs role and the territory involved. This matters especially where goods move between Great Britain, Northern Ireland, the EU and the rest of the world. The arrangements are not identical, and casual assumptions based on pre-Brexit practice have caused many avoidable problems.

Build customs information into the sales process

The best exporters do not treat customs data as something added by the dispatch department after the order is won. The product database should hold an approved commodity code, accurate description, country of origin where needed, net weight, and any known control requirements. Sales staff should be able to see when a quotation carries a duty or documentation implication.

There is a balance to strike. Not every occasional exporter needs an in-house customs specialist. Equally, no business should outsource all understanding of its own goods. External expertise is most effective when the exporter can provide clear facts and challenge an answer that does not fit the product.

The forthcoming Practical Export Guide addresses tariff classification alongside pricing, documentation, Incoterms and getting paid because these subjects are connected in daily trading, not separate administrative boxes. A mistake in one can undermine the work done in all the others.

A good customs record will not make a poor export proposition viable. It does, however, remove one of the commonest sources of preventable friction. Before promising a delivery date or a landed price, know precisely what is being sold, which code describes it and whose EORI will stand behind the declaration. That modest discipline is often the difference between an export order and an expensive lesson.
