Overview
TPU Dumbbells, factory direct
Thermoplastic polyurethane is injection-moulded rather than cast, which lowers tooling and unit cost while keeping the odour-free, non-marking behaviour that separates polyurethane from rubber. The surface is marginally softer than CPU. It is the right choice when a buyer wants the polyurethane story on the product page without the CPU price.

Container figures are planning estimates, not a guaranteed load. They are calculated as the lower of usable packed volume (28 / 56 / 68 m³ for 20 ft, 40 ft and 40 ft HQ) and gross payload (21.5 / 26 / 26 tonnes). Free weights are normally payload-limited, which is why a 40 ft high cube carries no more weight than a standard 40 ft. Actual loading is confirmed against your assortment and destination port before the proforma invoice is issued.
Figures marked in yellow are confirmed per model on the specification sheet supplied with your quotation. Container loading (net/gross weight, carton size, 20ft / 40ft / 40ft HC quantities) is issued with every quote.
Private label options
- Moulded or printed end cap

FAQ
TPU Dumbbells: FAQ
TPU or CPU: which should a distributor stock?
Stock both if you sell into two price tiers. CPU for chains and premium studios, TPU for mid-market commercial and higher-end home gym retail.
Does TPU smell?
No. Both polyurethane systems are odour-free from the carton, unlike recycled rubber.
What is the minimum order quantity?
Standard MOQ is 500 kg per SKU; private-label with a moulded logo starts at 1,000 kg per SKU, as does a custom Pantone colour. Mixed containers across dumbbells, plates, kettlebells, bars and sewn goods are accepted, and a first order is normally one 20ft container.
How long does production take?
Sampling normally takes two to three weeks after artwork approval. Bulk lead time runs 25 to 40 days depending on the line and coating, quoted per order with your proforma invoice.
Do you publish test certificates?
We publish specifications we can stand behind and we do not publish third-party certification we do not hold. Every batch is weight-checked against calibrated scales and inspected in house for coating, dimension and finish. Where a market or a tender requires independent test data, appoint your own testing or inspection agency — we will supply samples and arrange access to production. We would rather you verify than take our word for it.
