IS THIS RIGHT FOR YOU?

Who uses Inward Processing?

✓ You import raw materials or components to manufacture finished goods for export
✓ You repair or refurbish goods for overseas customers and return them
✓ You import goods for testing, calibration, or adaptation before export
✓ You sell a portion of your production into the UK market and export the rest
✓ Your goods will leave the UK in a processed, repaired, or finished state
✓ You have previously paid duty on materials that left the UK in a finished product
✓ You are in manufacturing, aerospace, automotive, electronics, or repair
✓ You are unsure whether IPR, Customs Warehousing, or another procedure applies

If you're importing goods into the UK to process, manufacture, repair, or refurbish them, and those finished goods are leaving the UK again, you may be paying duty you don't owe. Here's how to tell if IP applies to your situation:

Important: If your goods arrive and leave the UK unchanged, unprocessed and unsold, Temporary Admission or Customs Warehousing are likely the correct procedure instead. Using the wrong procedure results in HMRC demanding the full duty and VAT. Readyset will confirm which applies to your situation. Book a free consultation.

THE BASICS

What is the UK Inward Processing procedure?

Inward Processing is a HMRC customs special procedure that suspends customs duty and import VAT on goods brought into the UK for processing, repair or manufacture. The suspension lasts for the duration of the authorisation period and if the processed goods are re-exported, the liability is removed entirely. If the goods remain in the UK after manufacture, goods may be eligible for a lower, or 0 rate of duty even when remaining in the UK.

Suspension method

Duty and VAT are suspended at the point of import. If finished goods are re-exported, no payment is ever made. If goods are sold into the UK market, duty becomes due on the proportion entering free circulation, calculated at the point of discharge, not at import.

Drawback method

Duty and VAT are paid at import and reclaimed after re-export. Less common than suspension, but used where suspension is not practical. Readyset confirms which method applies to your specific supply chain before your application is submitted.

WHY IT MATTERS?

The core benefits of Inward Processing

💷
Immediate cash flow preservation
Stop the "pay and reclaim" cycle. Capital stays in your business, not an HMRC account, for the duration of the project.
🌍
Enhanced global competitiveness
Remove the duty burden from your manufacturing costs, price your exported products more competitively on the world stage.
⚙️
Operational flexibility
Import goods even when the final destination, domestic or international, is not yet confirmed at the time of import.
♻️
Repair and circular economy
The ideal mechanism for businesses engaged in refurbishment, import, repair, and re-export without duty liability.

For UK manufacturers, repair businesses, and processors, IP is one of the most powerful cash flow and competitiveness tools available, keeping your capital working rather than sitting in an HMRC account.

IP Re-Export Example
A UK manufacturer imports £1,000,000 of raw materials under IP, with £50,000 of import duty suspended. After manufacturing, 75% of finished goods are exported, with 25% sold into the UK market. Duty is only paid on the 25% entering free circulation.

Duty Inversion Example
A UK processor imports materials at a 4% duty rate. After manufacturing, the finished product has a new commodity code with a 0% duty rate. Under IP's duty inversion method, the lower rate of the finished product applies, not the higher rate of the imported material.

REAL WORLD SAVINGS

KNOW THE DIFFERENCE

Inward Processing vs other special procedures

Choosing the wrong procedure at the UK border is one of the most costly customs errors a business can make, HMRC will demand the full duty and VAT, regardless of intent. Here is how IP compares to the two most commonly confused alternatives.

Customs Warehousing
Storage without processing
Goods are held in a duty-suspended state until a decision is made about their destination — UK market or re-export. No processing or manufacturing takes place.
Use when → You need to store goods before deciding where they go. No processing involved.
Inward Processing ← you are here
Processing with duty suspension
Goods are imported specifically to be processed, manufactured, repaired, or incorporated — and the finished product is intended for re-export. Duty is suspended throughout.
Use when → You are changing the nature of the goods through manufacturing, repair, or processing before export.
Temporary Admission
Short-term use, no processing
Goods enter the UK for a specific, temporary purpose — an event, shoot, exhibition, or test — and leave in the same condition they arrived. No repairs, no modifications.
Use when → Goods arrive and leave unchanged — unprocessed and unsold.

THE COST OF GETTING IT WRONG

The risks of non-compliance with Inward Processing

HMRC treats duty suspension as a trust based privilege. Because IP involves a 100% tax suspension, audit scrutiny is intense. Errors, even innocent administrative ones, carry significant and immediate financial consequences.

Retrospective duty demands
If you cannot prove goods were re-exported or properly accounted for, HMRC will demand the full duty and VAT immediately, often years after the event, with no appeals on grounds of intent.
Bill of Discharge errors
Quarterly Bills of Discharge must accurately account for all goods in your IP regime. Errors, missing entries, or late submission trigger HMRC penalties and increased audit scrutiny.
Revocation of authorisation
Repeated compliance failures can lead to your IP authorisation being permanently withdrawn, damaging your import capability and competitiveness across the whole business.
Financial penalties under 2026 regulations
Under the latest HMRC regulations, failure to comply with directions for the movement of goods can result in civil penalties of up to £1,000 per error, applied per movement, not per overall shipment.

The most common failure we see isn't deliberate, it's businesses that set up IP correctly and then let the quarterly Bill of Discharge slip. HMRC doesn't distinguish between intent and negligence. The liability is the same either way.

Seen in practice

HOW WE WORK

The Readyset framework for Inward Processing

IP is routinely applied for without proper preparation, leading to rejected applications, delayed approvals, and compliance failures months later. Readyset plans ahead. We build the procedures, manage the application, and act as your technical lead throughout.

01
Feasibility and procedure design
We analyse your supply chain before anything is submitted. Is IP the right procedure? Which method — suspension or drawback? What yield rates, equivalence, and simplifications apply? We confirm the answers before your goods arrive at the UK border.
02
Application and HMRC management
We prepare and submit the full SP5 application to HMRC, managing all supplementary evidence requirements and correspondence. Approval timelines can be 4–6 months — we start the process early and manage HMRC directly throughout.
03
Procedure setup and systems
Once authorised, we build the IP procedure into your operations — Customs Procedure Codes, record-keeping structures, audit trails, and internal working instructions that meet HMRC's requirements from day one.
04
Ongoing compliance and Bill of Discharge
We manage your quarterly Bills of Discharge, track goods within your IP regime against HMRC time limits, and handle any audit queries. You focus on manufacturing — we handle the compliance calendar.

WHY READYSET

We don't hand you a checklist, we build the procedures.

Inward Processing is one of the most technically precise customs procedures available. The margin for error is zero, HMRC will demand the full liability the moment a deadline is missed or a Bill of Discharge is incorrect.

Most businesses either avoid IP entirely and pay unnecessary duty, or attempt it themselves and end up with unexpected tax demands.

Readyset plans ahead, manages every application, and acts as your technical lead during any HMRC audit or query.

IP works alongside these procedures

Inward Processing is one of several HMRC special procedures that can reduce your duty burden. Ask us how they interact with your specific trading pattern.

Frequently asked questions about Inward Processing

  • Inward Processing is for goods that will be changed while in the UK, through manufacturing, repair, or processing. Temporary Admission is for goods that arrive and leave unchanged, such as equipment for a shoot or exhibition. Using the wrong procedure results in HMRC demanding the full duty and VAT regardless of intent. Readyset confirms which applies to your situation before your goods move.

  • The standard approval timeline for a full IP authorisation (SP5) is 4 to 6 months. This includes the application, any supplementary evidence HMRC requests, and the formal authorisation letter. In some cases an Authorisation by Declaration is available for lower-value or infrequent movements, which is faster. Readyset starts the process early and manages HMRC correspondence throughout to avoid delays.

  • A Bill of Discharge (BoD) is a quarterly return submitted to HMRC showing all goods that entered and left your IP regime during the period, including quantities processed, waste, and the method of discharge. It must be submitted within 30 days of the end of each quarterly period. Missing a deadline or submitting inaccurate figures triggers HMRC penalties and increased audit scrutiny. Readyset manages every BoD submission so nothing slips.

  • Yes, IP allows for partial re-export. If a proportion of your finished goods are sold into the UK market rather than re-exported, duty becomes due on that portion only. The calculation is made at the point of discharge using the duty rate of the finished product, not the imported material. This is one of IP's most commercially useful features for manufacturers who supply both domestic and international customers.

  • Duty inversion occurs when the finished product has a lower duty rate than the raw materials or components imported to make it. Under IP, the duty rate applied at discharge is the rate of the finished product, not the higher rate of the imported inputs. This can result in a significant reduction in duty liability for manufacturers in sectors such as electronics, automotive, and aerospace, where raw material duty rates are high but finished product rates are low or zero.

  • HMRC may require a financial guarantee to cover the suspended duty and VAT during the authorisation period. The level of guarantee depends on the value of goods and the duty at risk. Businesses with AEO status can often secure a guarantee waiver, removing the need to tie up capital. Readyset assesses your guarantee position as part of the application process and advises on the most cost effective route.

  • Yes, but your IP authorisation must specifically cover all sites where goods will be processed or stored. Moving IP goods to an unlisted site without amending your authorisation is a compliance breach. Readyset ensures your authorisation covers all relevant locations from the outset, and manages any amendments if your operations change.

  • If a BoD is submitted late or not at all, HMRC treats the goods as having entered free circulation at the point the deadline passed, triggering the full duty and VAT liability immediately, calculated from the expiry date rather than the date you eventually submit. There is no grace period. Readyset tracks every deadline within your IP regime to ensure this never happens.

  • Yes. Readyset works with international businesses importing goods into the UK for processing, repair, or manufacturing. We manage the UK side of the authorisation, including the SP5 application, Customs Procedure Codes, discharge records, and any HMRC correspondence, regardless of where your business is based.
