Customs Assist
Meaning ~ Additions to the customs value representing costs of goods or services provided free or at reduced prices by the importer to the producer for manufacturing.
Engineering Services Exclusion
Meaning
Statutory tariff exemptions remove design and engineering work undertaken within the importing country from the taxable transaction value of imported goods. Importers rely on the engineering services exclusion to ensure domestic research and development expenditures are not taxed as dutiable assists at the border. The carve-out applies exclusively to technical work performed inside the importing nation territory, leaving offshore engineering fully subject to customs duties.
Clear geographic boundaries protect domestic engineering teams from unwanted tariff burdens.
Statutory Boundary
Geographic location dictates whether technical services increase entry valuation. Under international trade standards, engineering performed in the country of importation does not constitute a dutiable assist. Offshore CAD design or prototype modification performed in the manufacturer region remains fully taxable upon importation.
Documented Separation
Invoices must isolate domestic engineering charges from overseas manufacturing expenses. Applying the engineering services exclusion requires maintaining clear accounting records that prove where the design work was physically conducted. Blending domestic design costs into offshore tooling invoices forfeits the exemption during customs audits.
Compliance Verification
Regulatory auditors cross-reference purchase orders and payroll records to confirm where technical services occurred. Improperly claiming relief for offshore technical work results in duty underpayment liabilities and civil penalties. Detailed timesheets and engineering contracts provide the legal proof required to defend exempt status.
