Classification is the process of assigning a commodity code to a product for customs purposes. Commodity codes, also known as CN, HS, or tariff codes, are used globally to categorise goods for trade. These codes are typically ten digits in length, although they can vary between regions. For example, the same product may have different commodity codes in the UK, EU and US. This highlights the importance of accurate classification, as it is easy to apply an incorrect code when trading across multiple jurisdictions.
A commodity code determines several key aspects of customs treatment, including the rate of duty and import VAT, the applicable origin rules and whether any restrictions, licences or trade measures apply. Accurate classification is therefore essential for all businesses, and responsibility for getting it right sits with the importer, not with customers or suppliers. Having a clear process and understanding of classification is a critical part of any compliance framework. Businesses should ensure that classification is regularly reviewed and embedded within their internal processes to maintain accuracy and consistency.
BKR is highly experienced in the classification of goods. We work with hundreds of clients to support their classification requirements, ranging from full commodity code reviews across entire product ranges to day to day support where a specific code is required for an individual product.
Our team of specialists reviews all relevant technical information and applies practical industry experience to ensure products are classified accurately and efficiently. We cover all areas of the customs tariff and provide classification support across multiple jurisdictions, including the UK, EU and US. We can also assist with obtaining formal rulings or challenging those issued by HMRC in relation to classification. This may be required where HMRC is questioning a classification or raising an assessment, or where your business wishes to obtain certainty for key products through a binding decision.

We deliver practical, results-driven solutions designed to reduce costs, improve efficiency, and strengthen your overall approach to international trade.

Ad hoc classification
In many cases, businesses require classification support for a single product or a small range of goods to ensure accuracy and determine the correct treatment for duty, origin and licensing purposes.
BKR will provide a detailed report setting out the appropriate classification, the reasoning behind it and the associated duty rate. This can be used as part of your compliance framework to demonstrate that a considered and robust assessment has been undertaken.
Reclassification Services
Many businesses manage large product ranges, each requiring an accurate commodity code. In practice, these codes are not always reviewed or maintained, and errors are common.
BKR can carry out a detailed analysis of your customs data to identify potentially incorrect or misapplied classifications, including cases where duties may have been overpaid. We have helped clients recover significant amounts of duty through reclassification and can take a structured, risk based approach to reviewing and updating your product classifications.

Advance Tariff Rulings
Advance Tariff Rulings, also known as Binding Tariff Information (EU) or CROSS (USA) rulings, are formal decisions issued by customs authorities that provide legally binding confirmation of a product’s classification.
BKR can support your business in preparing and submitting these applications, ensuring that the technical evidence and supporting information are robust. Where appropriate, we can also help present a position that aligns with your commercial objectives while remaining compliant with the relevant legislation.

Customs classification is the process of assigning the correct commodity code to a product for customs purposes. This is sometimes also referred to as tariff classification or customs tariff classification. The correct commodity code determines the rate of Customs Duty, import VAT treatment, origin requirements, and whether any licences, restrictions, or trade measures apply. Because of this, accurate customs classification is a critical part of customs compliance for any importer or exporter.
Accurate commodity code classification is important because the commodity code applied to a product affects duty, VAT, origin, licensing, and customs declaration accuracy. If a business uses the wrong code, it may underpay or overpay duty, create compliance risk, or face delays at the border. A strong classification process helps businesses improve customs compliance, reduce operational disruption, and ensure goods are declared correctly in the UK and other jurisdictions.
A business may need customs classification support where it is unsure of the correct commodity code, is importing or exporting new products, is trading across multiple jurisdictions, or is concerned that existing codes may be wrong. Many businesses also seek commodity code advice where products are technically complex, difficult to classify, or where the duty impact is significant. In these cases, specialist tariff classification advice can help ensure accuracy and reduce customs risk.
Yes, incorrect tariff classification can lead to unnecessary customs costs. If the wrong commodity code is used, a business may overpay Customs Duty or fail to apply the correct origin or licensing treatment. In some cases, a review of historic customs classification can identify errors and unlock significant savings. This is why many businesses carry out reclassification services or seek customs classification advice to reduce duty exposure and strengthen compliance.
A business may want to apply for an Advance Tariff Ruling where it needs legal certainty over the customs classification of an important product. An Advance Tariff Ruling, sometimes referred to as Binding Tariff Information, provides an official customs decision on the correct commodity code. This can be particularly useful where goods are difficult to classify, where HMRC is questioning a code, or where a business wants stronger certainty for key imports or exports.
BKR provides a full range of customs classification services, including ad hoc classification for individual products, large-scale reclassification services, and support with Advance Tariff Ruling applications. We provide detailed commodity code advice, review technical product information, and deliver practical customs classification support across the UK, EU, and US. Whether a business needs help with a single commodity code or a broader tariff classification review, we help ensure products are classified accurately, efficiently, and in a way that supports compliance and cost control.
