Guangci
Nutraceuticals
An ISO 9001 and ISO 22000 certified functional-food plant in Dongguan making gummies, hard candy, tablet candy and solid beverage powders — strictly OEM, ODM and private label. There is no catalogue to order from: every export programme is formulated to the buyer’s own brief.
No product list — a set of dosage forms your brief gets built in.
Guangci exports on a pure OEM / ODM basis. It does not maintain a stock SKU catalogue for overseas buyers, and there is no price list to browse — what it offers is manufacturing capacity in four certified dosage forms, plus the formulation work to get a concept into one of them. Buyers arrive with an actives list, a competitor benchmark or a claim direction; the factory develops, produces and packs the result under the buyer’s own brand.
The four forms below sit inside the factory’s ISO 22000 scope and its Chinese export food producer filing — meaning they are the forms it is certified and customs-filed to produce and export.
The factory additionally states it runs effervescent tablet, capsule and powder programmes. These sit outside the dosage forms named on its current ISO and customs filings, so buyers planning those formats should ask for the specific scope documents before contracting.
From an actives list to a packed, documented carton.
Gummy & gel candy OEM
Pectin or gelatin gummies formulated to your actives, dosage, shape, colour and flavour brief. Gel candy sits inside the factory’s ISO 22000 and export-filing scope.
Tablet candy OEM
Chewable and swallow tablet candy — compression, coating and blister or bottle packing to your specification.
Hard candy OEM
Functional and nutritional hard candy, including single-wrap and pillow-pack formats for retail and sampling programmes.
Solid beverage OEM
Powder sachets and stick packs, covering plant solid beverage and probiotic solid beverage under the certified scope.
Formulation development
ODM route: bring a concept, a competitor benchmark or a target claim and the factory develops the formulation and dossier around it.
Private label & packaging
Bottles, jars, blisters, sachets, stick packs and cartons under your brand. Artwork and print coordination handled with the packaging supplier.
Documentation pack
COA, ingredient and specification sheets and export paperwork issued per shipment, matched to the destination market’s requirements.
Export & logistics
Registered foreign-trade operator with a customs export food producer filing on record and a U.S. FDA-registered facility number for U.S.-bound shipments.
MOQ, capacity, sampling and production lead times are not published for this factory. Because every programme is custom-formulated, those terms are quoted against the brief rather than fixed in advance — send the dosage form, formulation target, packaging format and volume and the factory will quote to it.
Certificates and filings with numbers you can check.
Every entry above corresponds to a certificate or filing document held on file at ChinaMakersHub. U.S. FDA food facility registration is a mandatory registration renewed on a two-year cycle — it is not an FDA approval, certification or endorsement of any product, and the importer of record remains responsible for labelling, claims and entry compliance. The factory has not provided GMP, HALAL, organic or third-party laboratory certificates, and none are claimed here.
A functional-food plant in Dongguan’s Fenggang corridor.
Dongguan Guangci Biological Medicine Science and Technology Co., Ltd was registered in Fenggang, Dongguan in January 2014, with a business scope spanning food and dietary-supplement production, plant extracts, special foods and import/export. Production runs on the third and fourth floors of its Fumin Road building — the specific area named on both its ISO 22000 and ISO 9001 certificates.
Its certified output is functional confectionery and powder: gel candy, hard candy, tablet candy and solid beverage, including plant and probiotic solid beverages. In practice that means gummy vitamins, chewables, functional lozenges and stick-pack powders — the formats supplement brands most often need a contract manufacturer for.
Overseas, Guangci works only as a manufacturer. It does not run its own export brand or a fixed SKU range, and it does not compete with the brands it supplies. Programmes come in as briefs and leave as the buyer’s product. Its priority market is the United States, with active interest across Canada, the UK, Australia, Southeast Asia, the Middle East, Eastern Europe, Latin America and Africa.
Twelve years of adding one filing at a time.
