Understanding Goods Classification in UK, Poland & Spain Trade

1. The UK: Commodity codes & the UK Global Tariff

In the UK, importers/exporters must use commodity codes via the official “Trade Tariff” service. theddcgroup.com+3GOV.UK+3uktrade.github.io+3

Key points for the UK:

The UK’s classification uses the HS-6 digits as the basis, and then adds further digits for national differentiation. Wise+1

The UK Global Tariff (UKGT) applies from 1 January 2021 for goods entering the UK from outside its preferential trade-arrangements. API Catalogue+1

The UK goods classification is divided into 21 sections (shown in Roman numerals) in the tariff tool. uktrade.github.io+1

Failure to classify correctly may lead to paying wrong duty, missing licensing requirements or delays. Scanlon Freight

Example risk: If you import a product described vaguely (e.g., “electronic accessory”) but classify under a generic HS code, you might face higher duty or need a licence that you didn’t anticipate. Using the UK Trade Tariff service ensures you find the correct code. GOV.UK+1

2. Poland: EU Customs Union, CN & TARIC based system

Since Poland is a member of the EU customs union, its goods classification falls under the EU’s system (i.e., the Combined Nomenclature (CN) and the Integrated Tariff of the European Communities (TARIC)). Trade.gov+2Taxation and Customs Union+2

Key points for Poland (and other EU Members):

The CN uses an 8-digit code structure: six digits from HS + two digits for EU subdivision. Taxation and Customs Union+1

TARIC codes go further (10 digits or more) and integrate EU measures (tariff quotas, suspensions, duty offsets) for each product/entry. Agencia Tributaria+1

Since Poland applies the EU’s Common Customs Tariff (CCT) for non-EU imports, duty rates are consistent across the EU external border. Trade.gov+1

Internal EU trade (goods circulating between EU member states) is often duty-free, but classification still matters for statistical, regulatory, VAT and internal movement purposes. icetransport.com+1

Example risk: If a UK exporter wants to send goods into Poland (or vice versa), though the duty may be zero (for EU internal movement), they still need the correct CN/TARIC code for the customs documentation. If they treat it like UK classification, they may mis-declare the code and face cost/time issues.

3. Spain: EU classification + Spain-specific customs procedures

Spain, as another EU member state, uses the CN/TARIC system for classification of goods. Agencia Tributaria+1

Key points for Spain:

Import duty rates from non-EU countries into Spain are determined via the TARIC system, accessible through the Spanish customs agency. Agencia Tributaria+1

For many industrial goods the duty is relatively low (e.g., 0-5% average). Trade.gov+1

Goods from outside the EU also attract Spain’s VAT (21% standard), with reduced rates (10% or 4%) for certain categories. blog.consultinghouse.eu+1

Example risk: If you export from the UK into Spain post-Brexit and treat it as internal EU movement mistakenly, you may overlook duty or VAT obligations or have the wrong classification under Spanish/TARIC rules, leading to delays or additional cost.

4. Key Differences & What They Mean for You

Here are some of the major differences and what exporters/importers should bear in mind:

Take-away points:

Always start classification using the HS-6 digits (the global baseline) then verify the national/EU specifics (UK commodity code vs CN/TARIC). Trade.gov+1

Use the country-specific tariff/commodity code lookup tools:

UK: Trade Tariff tool. GOV.UK+1

Poland/EU: TARIC / CN database. Taxation and Customs Union+1

Spain/EU: TARIC + Spanish customs site. Agencia Tributaria+1

Checking code accuracy is vital: wrong code can mean wrong duty, missing licences, wrong statistical reporting, or even export/import refusals.

Even within the EU (Poland/Spain), classification matters for internal movement, VAT, excise, quotas and preferential origin.
