The Hubs Standard

Quality control

How Hubs controls the quality of your parts

We’ve reinvented cross-docking for quality control

Cross-docking is mostly used to make shipping more efficient. We’ve added a crucial quality control element to our cross-docking process. In addition to extensive quality checks conducted on-site by manufacturing partners, parts of shipments are reassessed by Hubs’ source inspectors and/or QC teams at our Amsterdam and Chicago cross-docks. This applies to many globally sourced orders with an emphasis on critical line items.

Quality control from design to delivery

To ensure our parts always meet the Hubs Standard, we have in-house and on-site quality control (QC) systems and protocols in place. Every custom part gets checked on site by our manufacturing partners according to our guidelines. Depending on the manufacturing location and the complexity of the order, many parts undergo a second-inspection by Hubs' source inspectors and/or at our cross-docks before delivery.

We audit our manufacturing partners

All Hubs manufacturing partners (MPs) perform in-house quality checks before sending custom parts to our facilities or to their final destinations. We have teams on the ground responsible for regular audits across the supplier network, to ensure that every MP is consistently following the Hubs Standard for production as well as QC.

We do on-site quality control on a global scale

Alongside our cross-docks in Amsterdam and Chicago, we also have teams actively performing quality checks across the manufacturing network. Our on-site teams in China and India (with more on the way) inspect all outgoing orders using the Hubs Standard. If you’d like to receive a full QC report, you can request one when you order your custom parts.

“The team is always learning more and raising our benchmarks. Being a custom part manufacturer means that not every part fits existing standards, and it’s always a fun challenge to upgrade standards to fit our capabilities as they grow and improve.”
