Quality & Certification FAQs

We use incoming material checks, production-stage inspections and finished-product verification as part of our manufacturing quality activities.

For cable assemblies, relevant checks may include connector assembly, electrical continuity and workmanship. Our factory also includes equipment for cable durability and electrical verification.

The inspection plan depends on the approved product specification and relevant acceptance criteria. More information about our manufacturing quality approach is available on our Controllo qualità pagina.

These terms describe inspections at different manufacturing stages:

• IQC — Incoming Quality Control: checks purchased materials and components against defined requirements.
• IPQC — In-Process Quality Control: checks selected characteristics during manufacturing.
• FQC — Final Quality Control: verifies finished-product characteristics before release.

Checks at multiple stages help identify problems closer to where they originate instead of relying only on final inspection.

We determine inspection coverage according to the product, test method and agreed quality requirements. One inspection frequency does not necessarily apply to every product or characteristic.

Routine non-destructive checks, such as electrical continuity or basic functional verification, may be specified for every unit. Mechanical endurance, extended-operation and destructive tests are generally performed on selected samples.

For your order, we can clarify which checks use 100% inspection, which follow sampling plans and what acceptance criteria apply.

AQL stands for Acceptance Quality Limit. It is a parameter used in statistical sampling systems, including plans based on ISO 2859-1.

Lot size, inspection level, selected AQL and applicable sampling rules determine the sample size and acceptance or rejection criteria.

An accepted sample does not prove every item is defect-free. AQL is also not a guarantee of a fixed defect percentage in any individual lot.

When an inspection identifies a product or process that does not meet the applicable acceptance criteria, the affected output needs to be identified and controlled before release.

Our approach involves reviewing the nonconformity, assessing the affected products and determining an appropriate disposition. Depending on the findings, this may involve correction, rework, replacement or another approved action.

Products requiring corrective work should be re-verified against the relevant requirements before acceptance. For significant issues, we can discuss the investigation findings and any appropriate corrective-action evidence with the customer.

For repeat orders, we recommend referring to the same approved drawing, product specification or reference sample and identifying any revisions before production.

Critical characteristics may include conductor construction, connector dimensions, electrical ratings, materials, appearance and packaging.

You can ask us to review proposed substitutions or design changes and confirm which batch-identification or inspection records are available for the order.

USB cable testing can include continuity, wiring verification, short-circuit detection and conductor resistance checks.

Depending on the design, insulation, charging-current capability, electronic marking and data signal performance may also require verification.

A basic charging cable and a high-speed USB-C data cable have different requirements. Passing continuity testing alone does not establish compliance with a specified high-speed data rate.

Bending tests evaluate how a cable assembly behaves under repeated flexing, frequently near the connector strain-relief area. Our factory information includes bending-test equipment used for durability evaluation.

A test result should be interpreted together with its bend angle, applied force or load, cycle count and failure criteria.

Two cables passing the same number of cycles may not have equivalent durability if their test conditions differ.

Connector testing can evaluate mating and unmating forces, contact reliability and mechanical durability over repeated connection cycles.

The method and acceptance limits depend on the connector specification and application. USB-C, Micro USB and other connector types should not automatically be assigned the same durability requirement.

USB charger verification should reflect the advertised outputs and charging functions. Relevant checks can include:

• Output voltage and current at specified loads.
• USB PD and other supported charging protocol behavior.
• Multi-port power allocation, where relevant.
• Temperature rise, efficiency and applicable protection functions.
• Electrical safety and electromagnetic compatibility requirements for the target market.

Qualification and production tests must be selected for the exact charger model rather than assumed identical for all products.

AC/DC power adapters require verification related to their input range, regulated DC output and applicable safety requirements.

Relevant evaluation may include output regulation, load performance, efficiency, temperature rise, protection features and insulation.

Hi-Pot, or dielectric withstand, testing evaluates insulation integrity under defined conditions. It does not replace functional testing or constitute a complete safety evaluation.

Environmental verification should reflect materials, operating conditions and the intended application.

Relevant testing can include temperature, humidity, corrosion resistance and other environmental stresses where needed.

Salt spray testing helps assess certain metallic components or coatings under controlled conditions; it does not directly predict a fixed lifetime in real-world use.

Please identify unusual operating environments when discussing your product's test requirements.

ISO 9001 is a quality management system standard. Certification to ISO 9001 addresses an organization's management processes within its certified scope.

Product certification evaluates a particular product or product family against defined requirements in an applicable certification scheme.

An ISO 9001 certificate does not automatically make every product from that organization independently certified.

Check the certificate holder, scope and status separately from product-level compliance documentation.

No. CE marking indicates the manufacturer's declaration that a product meets the applicable EU requirements.

Depending on the legislation, conformity assessment may permit manufacturer self-assessment or require notified-body involvement.

CE marking is not automatically evidence that an independent laboratory certified every product characteristic.

RoHS restricts specified hazardous substances in electrical and electronic equipment within its scope.

RAGGIUNGERE is a broader EU chemicals regulation that includes certain restrictions and information obligations.

A RoHS test report does not automatically establish complete REACH compliance. Applicable requirements must be matched to the product, materials and market.

Compare the documentation with the precise model and configuration being purchased. Depending on the document type, check:

• Certificate holder or responsible legal entity.
• Covered model numbers and model family.
• Applicable standards and editions.
• Issue date, validity and current status, where relevant.
• Certificate or report number and issuing organization.
• Whether the purchased configuration falls within the stated scope.

Where possible, verify the document through the issuing body or official database. Similar appearance does not establish identical certification coverage.

No. Compliance obligations depend on product design, electrical characteristics, intended application and destination market.

A passive USB cable may have different requirements from an AC-powered USB charger or external power adapter. Products with active electronics can also have additional electromagnetic compatibility obligations.

CE, FCC, UL and UKCA represent different regulatory or certification frameworks. USB-IF certification is a separate industry certification program and does not replace applicable legal compliance requirements.

For private-label products distributed in several countries, each destination market and final product configuration should be considered when identifying required evidence.

No. USB-IF certification and Apple MFi are separate programs.

USB-IF certification concerns products evaluated under its relevant certification program, with official marks governed by program rules.

Apple MFi applies to certain accessory technologies covered by Apple's licensing program. It is not a blanket requirement for every USB-C cable.

Identify the intended connector, accessory technology and any required program approval before specifying certification requirements.

We can review certification and compliance requirements as part of an OEM/ODM project discussion.

Start by identifying the product configuration, intended application, destination markets and any specific standards or approval programs required by your customers.

Depending on the agreed project scope, support may involve reviewing technical requirements, preparing relevant product information or samples, and discussing testing or certification arrangements with appropriate external providers.

The required process depends on the product and applicable regulations. A new design may require its own evaluation even when it is based on an existing product platform.

Sì. We are an Apple MFi-authorized manufacturer and can support eligible accessory projects through the Apple MFi Program.

Our reference timeline for MFi certification is approximately 3–4 weeks. The actual schedule depends on the accessory design, program requirements, sample preparation, applicable testing, documentation and Apple's review process.

We review the proposed product and its required accessory technology before confirming the applicable development and certification steps. A product based on an existing design may still require its own verification or approval depending on the configuration.

The estimated period is a planning reference, not a guaranteed approval date. Final certification eligibility and approval remain subject to the relevant program rules.

You can request relevant documentation from us during technical evaluation, order preparation or before shipment.

Depending on the model and agreed inspection requirements, available materials may include:

• Applicable product test reports.
• Available finished-product or pre-shipment inspection records.
• Declarations of conformity.
• Material-related compliance documents.
• Relevant product or system certificates.

Please identify the model, purchase order, destination market and specific documents you require. We can then review which records exist and whether they apply to the purchased configuration.

Yes. Changes to materials, electrical components, circuitry, enclosures, insulation or connectors may affect the scope of existing compliance evidence.

Whether a new evaluation, amended report or updated certification is needed depends on the change and applicable assessment rules.

Even seemingly small changes should be reviewed for their impact on controlled product characteristics.

Before placing an order with us, confirm the technical and compliance requirements for the exact product:

• Approved model, configuration and product specification.
• Electrical, mechanical and functional requirements.
• Test methods and acceptance criteria.
• Inspection coverage, sampling plan and any agreed AQL conditions.
• Destination-market regulations and required documents.
• Material, labeling and other customer-specific requirements.

For customized products, identify changes that may affect existing testing or certification coverage.
