Caster buying questions, answered straight.
The questions importers, distributors and OEMs ask before their first CASTOVELLA order — on pricing policy, MOQ, tariffs, samples, branding and testing.
Why are there no prices on this website?
Because a caster price without its specification is meaningless — the same photograph hides different forks, bearings and tread hardnesses. CASTOVELLA publishes no prices anywhere, including the blog. Every quotation is written, and states the locked specification it is priced on.
What is your MOQ?
MOQ is confirmed per product and specification in the written quotation. Existing lines with standing tooling start lower than custom OEM builds. Tell us the product and your target quantity and the MOQ in the reply will be specific to that specification.
Which tariff heading will our US shipment use?
It follows the measured wheel dimensions. Wheels of 75 mm diameter or less — or wider wheels under 30 mm width — sit in 8302.20; typical heavy duty casters (100–200 mm, 40–50 mm wide) classify under 8716.90.30. Both carry 5.7% MFN and, for China origin, the same additional-duty stack (≈55.7% all-in at the time of writing). The full explanation is in the tariff guide; your broker makes the final call.
Can you supply under our own brand?
Yes — the OEM programme covers product branding, packaging and carton marks, with branded samples approved before production.
How do samples work and what do they cost?
Samples are production-representative units of a locked specification, measured before dispatch. Sample unit and freight costs are stated in the sample quotation for your destination — see the samples page.
What standards are your casters built and tested to?
Specifications follow the ISO 22883 and EN 12527–12532 framework; load performance is tested per EN 12532 / ANSI ICWM conventions. These are specification and test-method standards — we describe them as 'built to / tested per', and we do not present them as certifications. Details: quality & testing.
Do you hold stock we can buy immediately?
CASTOVELLA is a specification-led supply programme, not a stock catalogue: lines are produced against locked specifications and verified samples. Lead times are quoted per order — see shipping & lead time.
Can you match a caster we already buy?
Yes — send measurements (per the measurement guide) or a physical sample, plus the load case. The quotation locks the match dimensionally and materially, subject to the design-rights check any responsible manufacturer runs.
What are your payment and order terms?
Order terms are stated in the written quotation and proforma for each order. As with pricing, we do not publish a generic terms sheet that a specific order would then contradict.
Which port do you ship from, and can you consolidate lines?
FOB Ningbo is the default basis. Mixed-line consolidation in one container is the normal importer pattern across our range.
Do you sell to individuals or single-cart buyers?
CASTOVELLA is a B2B programme for importers, distributors, OEMs and volume buyers. Sample and trial quantities exist to serve programme evaluation, not retail purchase.
Who operates CASTOVELLA?
CASTOVELLA is the industrial caster brand operated by Ningbo East Packaging Technology Co., Ltd., based in Ningbo, China. Contact details are on the contact page.
