Import customs for manufactured parts affects cost, lead time and legal responsibility. A technically correct shipment can still be delayed when the commodity code, origin, customs value or documents are incomplete. Import planning should therefore begin during sourcing, not when goods reach the border.
Identify the importer and declarant
Define who is the importer of record, who submits the declaration and who provides supporting data. The Incoterm influences commercial responsibilities but does not automatically resolve all customs obligations.
Classify the parts correctly
Goods entering the EU need a classification under the Combined Nomenclature and TARIC framework. Classification determines duty rates and possible non-tariff measures. The material alone is not always decisive; function, construction and the product in which the part is used can matter.
Keep a documented classification rationale and review it when the product changes. For uncertainty, consider formal customs guidance.
Determine origin
Origin is the economic nationality of the goods, not simply the shipping country. Preferential origin may reduce duty when the applicable agreement and evidence support it. Non-preferential origin also affects trade measures and marking.
Do not accept an origin statement without understanding the production route and required proof.
Calculate customs value
The transaction value is commonly the starting point, subject to additions and deductions. Tooling, assists, commissions, royalties, freight or insurance can affect the calculation depending on circumstances. Keep contracts and invoices consistent with the declared value.
Prepare the document set
- Commercial invoice with buyer, seller, description, quantity and value.
- Packing list and transport document.
- Commodity code and origin evidence.
- Required licences, declarations or product-compliance records.
- Insurance and Incoterm information where relevant.
Descriptions such as “machine parts” are often too vague. Use a technically accurate commercial description.
Account for duty and import VAT
Duty depends on classification, value and origin. Import VAT is calculated under the applicable rules and may include duty and incidental costs. Confirm cash-flow treatment and local arrangements with a customs or tax specialist.
Align packaging and inspections
Packages should match the packing list and allow customs examination without damaging critical surfaces. Wood packaging and controlled materials may have additional requirements.
Prevent common delays
Typical problems include inconsistent invoices, wrong quantities, unclear origin, missing preference evidence and last-minute changes to the consignee. Use a pre-shipment document check and provide the broker with product information before arrival.
The broader customs guide for outsourced manufacturing explains the wider sourcing context, while outsourcing logistics and customs covers operational coordination.
Build a customs data pack before shipment
Create a controlled file containing the product description, commodity code rationale, origin evidence, invoice, packing list, transport document and agreed Incoterm. Check that quantities, weights, values and buyer or seller details match across the documents. Inconsistent information often causes questions that could have been resolved before dispatch.
If a component contains several materials or is part of a larger assembly, use a description that explains its function instead of a vague label such as “metal parts”. For the logistical side of the shipment, see our guide to outsourced manufacturing logistics and customs.
Assign responsibility for exceptions
Agree who responds when customs requests technical information, proof of origin or a revised value. Keep drawings and commercial data available without disclosing more intellectual property than necessary. When sourcing decisions are made, include duty, import VAT timing, brokerage and inventory in the total cost of ownership.
After the first shipment, compare the declaration with the planned data pack and record any customs questions or corrections. Reuse the verified information for repeat orders, but reassess it when the product, supplier, origin, price structure or trade rules change.
Conclusion
Importing manufactured parts reliably requires accurate technical data and clear customs ownership. TOS coordinates suppliers, documents, freight and customs partners so import requirements are built into the production route.
