Quality control & compliance

How quality is controlled

Quality is controlled at each stage rather than inspected at the end. These are the checks built into a standard order:

• Incoming material checked for grade, density and colour before production.
• Wall thickness and dimensions measured on finished units, not on the raw material.
• Function testing — inflation, valve cycles, resistance range and buckle operation.
• Set assembly checked against the component list before boxing.
• Pre-shipment inspection on packed cartons — count, dimensions, assembly, packing.

What to check on the sample

Most disputes are settled at sampling. Check these before bulk production starts:

• Actual dimensions and wall thickness against the specification.
• For balls: inflation, valve function and the anti-burst specification.
• Resistance level measured, not assumed from the colour code.
• Surface texture and grip against a mat.
• Whether the components work together as a set when packed.

Documentation

Depending on the market you sell into, one or more of the following will be requested by your buyer or your customs broker. We provide them on request and keep them on file for repeat orders:

• Material and density stated in writing for every component.
• REACH statement and phthalate reports for polymer components.
• Latex statement for rubber components, with a latex-free option where required.
• Textile certifications where a safety claim is being made.
• Packaging material declarations, including recycled content where claimed.

Third-party inspection

Third-party inspection and factory visits are welcome, and we will work to the inspection protocol you set. Give us the inspection date early enough that a failed finding can still be corrected within the production window rather than pushing the shipment.

Materials and what they mean

A set mixes materials, and each behaves differently. Silicone is stable, low odour and tolerant of repeated cleaning, which is why it belongs on skin-contact parts. TPE is lighter and more recyclable with grip slightly below premium silicone unless the formulation is tuned. EVA should be specified by density rather than thickness — low-density foam collapses within months and dates the whole set. Fabrics and polymers render one brand colour slightly differently, so decide which is the reference before sampling.

Next step

To put this into practice, start from the product range and then read the guide closest to your next decision. Tell us which documents your market requires and we will confirm what we can supply and what has to come from a third-party lab.
