TRADER SUPPORT SERVICE
‍
ACCURATE & COMPLIANT

What are Trader Support Services

The Trader Support Service (TSS) is a free, government funded service provided on behalf of HMRC to help businesses move goods between Great Britain and Northern Ireland. Launched in 2020, it supports traders of all sizes to comply with the Windsor Framework, the arrangements governing the movement of goods into Northern Ireland after Brexit.

Through the TSS portal, registered businesses can have customs declarations, safety and security declarations and related processes completed on their behalf at no cost, alongside access to guidance, training and specialist customs support.

While the TSS submits declarations for you, your business must enter and provide all the information associated with each movement, and legal responsibility for customs compliance stays with you. BKR helps you get the most from the Trader Support Service, from TSS registration and onboarding to setting up accurate commodity codes, customs values and origin data. We also advise on the UK Internal Market Scheme (UKIMS), goods “not at risk” of entering the EU and duty reimbursement, and help resolve TSS queries and errors so your goods keep moving between GB and NI.

Benefits of TSS Support

Using the Trader Support Service can be complex and time consuming, and for most businesses it sits outside their core activities. Outsourcing your TSS declarations to BKR can benefit your business in three key ways.
01.

REDUCE THE COST OF TSS DECLARATIONS

While the TSS itself is free, completing your own TSS declarations is not. Training staff, committing internal resource and correcting errors all add up. As a result, many businesses find that using a dedicated TSS support service actually saves them money.
02.

IMPROVE ACCURACY AND COMPLIANCE
‍

Our team are fully trained and experienced in using the TSS portal, from entering commodity codes and customs values to selecting the correct TSS document codes. This means the information we submit is accurate and compliant, reducing rejected declarations, amendments and the risk of HMRC penalties.
03.

MEET TSS DEADLINES EVERY MONTH
‍

Businesses are responsible for submitting their TSS supplementary declarations by the 10th day of the month following the movement of goods. Many struggle to meet this deadline, particularly during staff holidays or busy trading periods. With a dedicated and experienced team managing your TSS declarations, you always have cover and your declarations are submitted on time.

What We Do


BKR has a dedicated and experienced team of customs professionals who submit TSS declarations on behalf of businesses moving goods between Great Britain and Northern Ireland. We have submitted thousands of TSS declarations for our clients, managing both ongoing monthly declarations and backlogs of overdue historic declarations.

Our team take the time to understand your business, your freight activities and how your goods move, so we can provide accurate, high quality support and ensure your goods are declared compliantly to HMRC through the TSS portal. Because our team are trained in both the Trader Support Service and traditional customs declarations on CDS, we bring practical experience, efficient use of systems and a strong understanding of customs compliance to every declaration we submit, including the correct use of TSS document codes.

One of the most common challenges traders face on the TSS portal is selecting the correct document codes. TSS document codes, also known as customs document codes or CDS document codes, tell HMRC which certificates, licences, invoices and supporting documents apply to your goods, or confirm that a waiver or exemption applies. Using the wrong document code can lead to rejected declarations, delays at the border or incorrect duty being charged. BKR’s team are trained in every TSS and CDS document code and can quickly identify exactly which codes your goods require.
