A tablet looks like the simplest supplement format on the shelf. It is a compressed disc of powder, it needs no gelling system, no sachet filler, no cold chain. That simplicity is real on the line and misleading on the specification sheet, because almost everything a buyer cares about — whether the tablet survives freight, whether it tastes of chalk, whether the label claim still holds at month eighteen — is decided by powder decisions made weeks before the first tablet is pressed.
In Chinese factory paperwork the category is written as tablet candy (压片糖果), and it covers both the chewable tablets a consumer bites and the pressed tablets they swallow. This guide walks through how that category is actually produced to a buyer's brief, what belongs on the specification you hand a contract manufacturer, and how to confirm a factory is filed to make the form before you invest in development.
Tablet candy is a filing category, not a marketing word
Chinese export manufacturers are registered against named product categories rather than against "supplements" as a general activity. Tablet candy appears as its own line in an export food producer filing and as its own wording in an ISO scope certificate, separate from gel candy, hard candy and solid beverage. A factory that makes excellent gummies is not therefore cleared to press your tablets, and the reverse is equally true.
Guangci Nutraceuticals, a Dongguan contract manufacturer listed on this platform, is a useful worked example because its documents are specific. It was founded in 2014 in Fenggang, Dongguan, and holds China export food producer filing 4400/11384, issued by Fenggang Customs, covering tablet candy, gel candy, hard candy and solid beverage. Its ISO 9001:2015 and ISO 22000:2018 certificates (Zhongjian Certification, valid to 7 October 2026) name the same four categories. It also holds U.S. FDA food facility registration No. 17267166330, which is renewed biennially and is a notification of existence rather than any form of approval.
Those four artefacts are the ones worth reading before a technical conversation starts. The pattern generalises: ask for the filing, read the category wording, and match it against the form you intend to sell. The wider document set is set out in this guide to documents to request before a first order.
Three routes to a tablet, and what each one costs you
How the powder is prepared before compression is the decision that drives cost, stability and how the tablet behaves in the mouth. Three routes dominate contract manufacturing, and a factory will normally propose one based on your actives rather than on preference.
| Route | How it works | Suits | Trade-off |
|---|---|---|---|
| Direct compression | Actives blended with excipients and pressed straight away | Free-flowing, heat- or moisture-sensitive actives; shorter development | Needs good powder flow; high-dose or sticky actives often will not run |
| Dry granulation (roller compaction) | Powder is compacted into ribbon, milled to granules, then pressed | Moisture-sensitive actives that still need better flow and uniformity | Extra step, some fines generated, modest yield loss |
| Wet granulation | Binder solution added, granulated, dried, then pressed | High-dose botanicals and poor-flow powders; robust tablets | Heat and moisture exposure; longest cycle; unsuitable for some probiotics |
Ask which route is proposed and why. The answer tells you how much of your formula the factory has actually thought about. If a manufacturer proposes wet granulation for a live-culture product without discussing the drying step, that is a signal to slow down.
The specification that keeps a chewable from failing at retail
Chewable tablets fail commercially in mundane ways: they arrive chipped, they crumble in the bottle, they taste bitter on the finish. A specification with acceptance limits prevents most of it. The parameters below are standard in the industry and should appear on the document both sides sign.
- Weight and weight uniformity — target weight plus an allowed deviation, sampled across the run rather than at the start.
- Hardness — expressed in newtons or kiloponds. Chewables sit deliberately softer than swallow tablets, which is why they need tighter packaging protection.
- Friability — the standard test is described in USP General Chapter <1216>, and a loss of not more than 1.0% of tablet weight is the conventional limit. Confirm the current chapter text with your technical lead.
- Thickness and diameter — these drive blister tooling and bottle fill, so freezing them early avoids repeat packaging costs.
- Disintegration — relevant to swallow tablets under USP <2040> for dietary supplements; chewables are generally treated differently because they are chewed, which is exactly why hardness and mouthfeel carry more weight in their acceptance criteria.
- Organoleptic acceptance — taste, colour and mouthfeel judged against a retained gold-standard sample, not against a written adjective.
The retained sample matters more than most buyers expect. "Slightly sweeter than the approved reference, retained 12 August" is contestable at inspection; "pleasant flavour" is not. The same discipline applies across dosage forms, and the sequencing is covered in the guide to choosing a supplement dosage form.
What your actives do to the tablet, and the reverse
Compression is a mechanical process applied to a chemical mixture, so the formula and the format negotiate with each other. Four constraints come up repeatedly in briefs.
Dose volume. A high-milligram botanical extract may simply not fit in a tablet a consumer will chew. The honest options are a larger tablet, a two-tablet serving, or a different form — and it is cheaper to hear that in week one than after tooling.
Moisture and hygroscopicity. Vitamin C, some mineral salts and many botanical extracts pull water from the air. That drives the granulation route, the packaging decision and the shelf-life claim together, not separately.
Heat sensitivity. Probiotics and some vitamins lose potency through drying steps. Where a claim depends on counts at end of shelf life, overage has to be designed in and justified with stability data rather than assumed.
Taste. B vitamins, zinc and many plant extracts are bitter. Masking is done through sweetener system, flavour and sometimes coating, and each of those choices touches the label. Sugar alcohols such as sorbitol and xylitol are common in chewables and carry their own labelling and tolerance considerations in several markets.
Reading the factory's filed scope before you send the brief
Two checks take a few minutes and remove most downstream risk. First, read the export food producer filing and confirm tablet candy is named in it. Second, read the ISO certificate scope wording rather than the certificate number, because the scope is where the categories actually appear.
Beyond the paperwork, the questions that separate a serious quotation from an optimistic one are practical: which route is proposed for this formula, what stability programme supports the shelf-life claim, who owns the formula if you move production later, and how change control is handled once the specification is frozen. The ownership question in particular is decided by the commercial model rather than by goodwill, which is why it is worth settling alongside the OEM, ODM and private label distinction before development spend begins.
If you intend to audit, the on-site sequence for a supplement plant — document room first, then traceability walk-back — is set out in this guide to auditing a supplement factory in China. Where certification claims are involved, the differences between ISO 22000, HACCP and GMP are worth knowing before you accept a badge at face value.
Packaging, market entry and the numbers a buyer will test
Chewables are softer than swallow tablets, so packaging is part of the product rather than an afterthought. Blister packs protect individual units and suit sampling and travel formats; bottles with induction seal and desiccant suit daily-use products and are cheaper per unit at volume; stick-style tubes appear in impulse and point-of-sale positions. The decision interacts with the moisture profile of your formula, which is why it belongs in the same conversation as granulation.
On market entry, classification deserves early attention. Gummies commonly move under HS 1704.90; pressed tablets containing added vitamins or botanicals may instead be classified as a food preparation, and the correct code depends on composition. Treat the code as something to confirm per product specification with your customs broker rather than something to copy from a supplier quotation.
For the United States specifically, the Supplement Facts panel is prescribed by 21 CFR 101.36, and importers carry obligations under the Foreign Supplier Verification Programs rule. Both sit on the importer of record, not on the Chinese manufacturer, and both are easier to satisfy when the documentation is requested during development. The sequence is covered in the guide to importing dietary supplements from China to the USA.
Guangci operates as a pure OEM, ODM and private-label manufacturer without a stock catalogue, and states that production runs in a 100,000-class (approximately ISO Class 8) clean workshop on automated lines with small-batch customisation supported. Buyers comparing that offer against a gummy programme will find the tablet route generally simpler to specify and to pack; the comparison itself is set out in our private-label gummy manufacturing guide.
Common questions
What is tablet candy in a Chinese factory quotation?
Tablet candy is the Chinese regulatory and industry term for compressed supplement tablets, covering both chewable tablets that are bitten and swallow tablets, and it appears as a distinct named category in a manufacturer’s export food producer filing and in the scope wording of its ISO certificates. A quotation using the phrase is describing pressed tablets rather than a confectionery novelty.
What is the difference between a chewable tablet and a pressed tablet?
A chewable tablet is formulated to break down in the mouth and is therefore compressed to a lower hardness with a sweetener and flavour system designed for taste, while a pressed swallow tablet is harder, smaller for its dose and formulated to disintegrate in the stomach. The two share a production line but differ in excipients, hardness targets and packaging protection.
How do I verify that a China factory can legally make tablet supplements?
To verify that a Chinese factory may legally produce tablet supplements for export, request its export food producer filing and its ISO 9001 and ISO 22000 certificates, then read the scope wording rather than the certificate numbers and confirm that tablet candy is explicitly named among the registered product categories. A factory cleared for gummies or powders is not automatically cleared for tablets.
Which tablet manufacturing route should my formula use?
The manufacturing route depends on your active ingredients: direct compression suits free-flowing actives and shortens development, dry granulation through roller compaction suits moisture-sensitive powders that still need better flow and content uniformity, and wet granulation suits high-dose botanical powders that tolerate heat and moisture during processing. Ask the manufacturer to state which route it proposes and why.
Does a US FDA registration number mean the tablets are FDA approved?
A U.S. FDA food facility registration number does not mean a product is FDA approved: it confirms only that a facility has notified the agency of its existence and renews that notification every two years, and it involves no product inspection, testing or endorsement of any kind. The FDA does not approve food or dietary supplement factories, so “FDA approved” is never an accurate description.
If you are scoping a tablet programme, the fastest route to a comparable quotation is a brief that states the dosage form, the serving payload, the target market and the packaging format. Send that brief and it can be matched against manufacturers whose filed scope already covers pressed and chewable tablets, including Guangci Nutraceuticals in Dongguan.
