The factory
A working factory you can audit, not a trading desk.
Founded in 2019 in Liaocheng, Shandong. Clay is mixed, shaped, cured, packed and inspected on our own line by our own QC team — the same shift that signs off the sample signs off your container.

Compliance
Audited, not just certified.
Three independent checks cover the product and the people who make it — the set most European and North American buyers ask for before the first order.
EN71
EU toy safety
EN71-1, EN71-2 and EN71-3: mechanical strength, flammability, and migration of heavy elements — including lead, cadmium and barium.
amfori BSCI
Social compliance
Audited under amfori BSCI: working hours, wages, health and safety, and the absence of child, forced or trafficked labour.
Copies of current reports are sent with every quotation — or on request before you commit to anything.
What we make
Four ranges, one certified factory.
Every kit ships from the same line, under the same 17-point quality process — so a mixed container is still one conversation.

Why Siglo
The parts of sourcing that usually go wrong, handled.
Buyers do not switch factories for a better catalogue — they switch for fewer surprises. These are the four we designed the business around.

OEM and ODM across clay colour, tooling, packaging and private label. Design proofs land within five business days, and nothing runs to mass production until you approve a physical sample.
Logistics you can promise your buyer
