Customs Declaration Software for Electronics Trade

Bring technical product detail into a clearer customs workflow. CDUK lets your team prepare GB declarations from checked product information, with document extraction and reusable shipment data. You file in-house, directly with HMRC, and see every line before it goes. Every filing, for components in or finished devices out, sits in one account.

  • GB CDS declarations
  • AI document processing
  • Multi-item editing
  • Reusable product data
Discuss your electronics shipments
  • Start from a template for each product familySupplier, parties and goods are already in place, so each order starts ready to review.
  • Apply saved settings to a product modelReuse the commodity settings your team saved for each model, ready to review on every order.
  • Check battery and model details per lineSee which lines have settings applied and which need a battery or conformity check.
  • Fix gaps early, then submit it yourselfMissing fields are listed by section. Complete them, then file directly from your own account.

In a nutshell

Electronic products can look near-identical on an invoice while serving very different functions. A model number identifies a product inside your business. It does not explain what the product does, and function, specification and composition are what a classification decision rests on.

Customs Declarations UK (CDUK) lets your team bring GB customs filing in-house through the Customs Declaration Service (CDS). Commodity search and CDS requirements mapping guide each line, AI document processing turns invoices into a reviewable draft, and multi-item editing handles mixed shipments of devices, chargers and parts.

You prepare each declaration, check it and submit it directly to HMRC, with built-in checks and our UK support team behind you. Pay as you go, with no monthly fee and no minimum volume.

Why electronics is different

Describe the function, not just the model.

Collect the facts a reviewer needs before a code is chosen, not after a query arrives. CDUK keeps product detail, documents and goods lines together, so your team can see why each line says what it says.

  • Model numbers hide function

    Two products with similar names can do different jobs. Capture what each one does, its specification and relevant composition, then use UK Tariff lookup and commodity requirements to guide the classification you select. The decision stays with your team, and the audit trail records what was chosen.

  • Accessories, components and devices differ

    A power supply sold on its own, a part inside a device and a complete device may each need different treatment. Keep each as its own goods line so every decision is made and recorded for the right product.

  • Mixed invoices are common

    One invoice can combine devices, power supplies, spare parts and accessories, with different origins and values on adjacent lines. Multi-item editing and bulk upload keep long invoices quick to prepare.

  • Specifications live elsewhere

    Data sheets and technical files rarely travel with the invoice. Bring them into the same review, so the description matches the goods in the box and your team does not file from the invoice alone.

  • Reuse needs a re-check

    Saved parties, templates and declaration cloning remove retyping on repeat models. A revised specification, a different factory or a new origin is a prompt to check the line again, and validation helps you spot it.

  • Customs is one of several checks

    Battery transport rules, product conformity and export controls sit alongside the declaration. CDUK records the battery and product detail on the line so those checks can be planned from the same data.

Illustrative examples

From model number to a reviewable description.

Product detail captured per model, then a mixed invoice where each line type keeps its own description. Both examples show how your team sees and checks the facts in CDUK. They are illustrative and assign no code or treatment. The next shipment of the same model starts from a reviewed description.

Product detail

Model, function, customs description.

Record the function and specification beside each model, then draft a description your customs reviewer can use. Lines without enough detail are flagged, so your team completes them before anything is classified and submitted.

  • Keep the internal model number for traceability
  • Add function, specification and relevant composition
  • Check the description against the technical documents and the invoice
  • Use HMRC's commodity code guidance alongside CDUK’s search
Mixed invoice

Keep goods lines separate where treatment differs.

Extract the invoice with IDP, check quantities and values, then keep devices, power supplies, spare parts and accessories as separate lines wherever their treatment might differ. One draft, one review, one submission. Extraction carries no per-document fee.

  • Use bulk editing for details that genuinely apply across the selected items
  • Check item-specific origin, codes and supporting documents line by line
  • Spot disagreements between invoice, packing list and transport document before submitting
Line types

What to capture for each kind of line.

The table lists the detail your team collects for each kind of line. Capture it once and every later declaration for the same product starts from a reviewed record.

Line typeDetail to captureWhy keep it separate
Complete devicesFunction, key specification, modelFeatures that define the product can differ between models
Power supplies and chargersInput and output specification, intended useCan be treated differently from the device they ship with
Spare parts and componentsWhat the part is, what it fits, whether it is usable aloneA part is classified differently from a finished product
AccessoriesFunction and whether sold with or without a deviceAccessories are classified on their own characteristics
Battery-containing goodsBattery type and size, as stated on technical documentsRecorded so the separate checks can be planned

Classification follows the actual technical characteristics and tariff rules. The decision is yours, and CDUK guides and checks it with tariff lookup and validation.

Repairs and replacements

Plan the purpose of the shipment before dispatch.

Record whether a shipment is a sale, a warranty replacement, a repair or a return. The customs procedure and value reflect the circumstances, and your team prepares each flow in the same CDUK account, with templates for the ones you repeat.

A commercial sale

  • GB CDS import
  • GB CDS export

A sale has a seller, a buyer and a commercial value. Check that the invoice, the order and the goods all agree, then prepare the declaration from an extracted draft and submit it directly to HMRC. Your team sees every line before submission.

  • Invoice value and delivery terms
  • Product detail per line
  • Origin information per line
Discuss sales shipments
Separate checks

What a declaration does not establish.

Customs acceptance and these obligations are different matters, even when the same data sheet informs both. CDUK prepares the declaration and records the product detail, so your other checks start from the same facts.

In the declaration

What you prepare in CDUK

  • Goods lines from checked product information
  • Commodity search and CDS requirements mapping
  • Origin, value and procedure fields

What runs alongside it

  • Battery transport requirements
  • Product conformity requirements
  • Export-control checks, licences and destination checks
  • Screening of goods and parties for export-control purposes
Frequently Asked Questions

Questions from electronics businesses.

Can AI classify a device from a model number?

A model number alone does not describe the goods, so classification should rest on the technical characteristics and the tariff rules. CDUK’s commodity search and requirements mapping guide your team, and your reviewer makes the final decision, recorded in the audit trail.

Does the platform screen dual-use goods?

Dual-use and export-control screening is not part of the platform, so licence and destination checks run alongside your CDUK filing. CDUK gives you clean, consistent product and party data to feed those checks, and a visible record of what has been filed.

Can we reuse product information?

Yes. Saved parties, templates and declaration cloning remove most retyping, and validation prompts you to check changes to the specification, origin and shipment before submitting. See reduce manual data entry for how the time savings add up.

How should mixed invoices be handled?

Extract the source data with IDP, check quantities and values, and keep goods lines separate where their treatment differs. Use bulk editing for details that genuinely apply across the selected items, and check origin, codes and supporting documents per line before you submit.

Does a battery change the customs process?

Record the battery type and size from the technical documents against the line, so the declaration and your transport and conformity checks work from the same facts. The panel above shows what runs alongside the declaration.

Is there an electronics-specific integration?

Product and order data can reach CDUK through an ERP, TMS or WMS connection via API, scoped with our team around the fields you hold. Tell us your system and we will map it. See connecting ERP, TMS and WMS data.
