Soda Maker Certificates: What Importers Ask For | 4°

Certificates are the part of a soda maker project that arrives as a surprise, usually two weeks before the ship date. Here is the whole list, grouped by who is asking.

Written by the 4° engineering team · Foshan, China

Three different people ask for three different things

Buyers tend to treat "certificates" as one folder. It is really three folders that answer to three different parties: your own quality system, your market's regulators, and the carrier moving a pressurised cylinder.

DocumentWhat it actually coversWho asks for it
ISO 9001 / ISO 14001 The factory's quality and environmental management system — and the stated scope, which on ours is the R&D and assembly of soda makers Your own sourcing or quality team
BSCI social audit Labour conditions and social responsibility at the manufacturing site European retailers and larger brands
LFGB (EU) / FDA (US) Food-contact safety of the materials that touch drinking water — bottle, seals, tubing Customs, retail compliance, your insurer
RoHS / REACH Restricted substances and chemical safety in materials and electronics EU importers, retail listings
PET GB 4806.6 The Chinese food-contact standard for PET — relevant when the bottle is moulded in China Chinese export inspection and some buyers' own specs
Packaging PPWR Packaging and packaging waste compliance for the EU market EU retail compliance
CO₂ CoS / MSDS Certificate of conformity and safety data sheet for food-grade carbon dioxide Carriers, customs, and any buyer filling cylinders
TPED / DOT Pressure-equipment approval for cylinders — the EU and US schemes respectively Carriers and customs wherever cylinders are shipped

What each one is really telling you

ISO 9001 is about the system, not the product

A quality-system certificate says the factory has a documented process and that an auditor checked it. It does not say your machine will pass your market's tests. The part worth reading is the scope line: a certificate for "electrical appliances" and a certificate for "the R&D and assembly of soda makers" are different documents, and only one of them is about your product.

Food-contact documents are where the bottle lives

On a soda maker the material that matters is the one holding the water: the bottle, the seal and the tubing. This is why the bottle is not a detail you can leave to a supplier — if the factory buys bottles in, the food-contact story belongs to someone else's paperwork. We blow-mould ours in a 300 m² dust-free workshop, so the material and the process are both in the same building as the machine.

RoHS and REACH are about what is in the product

RoHS covers restricted substances, mainly in electronics. REACH covers chemical substances more broadly. Both are usually requested as test reports rather than certificates, and both are worth reading for the model name on the cover — a report for a different machine is not evidence about yours.

The cylinder is a separate project

A CO₂ cylinder is pressure equipment, and it travels under its own rules. Depending on the destination you will be asked for approval under TPED (Europe) or DOT (United States), plus a certificate of conformity and a safety data sheet for the gas itself. Buyers routinely discover this after the machine is booked, which is a bad week to learn it.

How to check a certificate in four minutes

  1. Get the number, not the picture. Ask for the registration or report number and the issuing body.
  2. Look it up on the issuer's register. Most certification bodies publish a searchable database. A number that cannot be found is a scanned decoration.
  3. Read the scope and the model. The document has to name what you are buying, and the legal entity has to match the one on your invoice.
  4. Check the dates. Expired is not the same as non-existent, but it does mean your retail listing may stall later.

What we hold

We publish ours rather than sending a folder on request: ISO 9001 and ISO 14001 (issued 2025-08-12, valid to 2028-08-05, scope — R&D and assembly of soda makers), a BSCI social audit, packaging PPWR, LFGB and FDA for food contact, RoHS and REACH for materials, PET GB 4806.6, and CoS, MSDS, TPED and DOT for the CO₂ cylinders. Scans of the originals, with the registration numbers, are on the patents and certificates page.

The other half of the same question is the design side: 60 granted patents across 4° and MIA, 56 of them in force. Those are also public documents, and the list is downloadable from the same page.

Put it in the schedule, not in the panic

Ask for the documents you need at the quotation stage and write the ones that do not exist yet into the timeline as a task with a name against it. A certification you have to generate adds weeks; one the factory already holds adds nothing. Knowing which is which is the difference between launching on the date you promised your buyer and explaining a delay.

Tell us where you sell and what you are shipping, and we will tell you which documents you will be asked for — including the ones we do not hold and would have to run for your product.

Common questions

Which certificates does an importer actually ask for?
Three groups. System certificates: ISO 9001 and ISO 14001, sometimes a social audit such as BSCI. Product compliance for the destination market: food-contact documents (LFGB for the EU, FDA for the US), RoHS and REACH for materials, and packaging regulation such as PPWR. Transport documents for the cylinder: certificate of conformity or safety data sheet, plus TPED or DOT depending on where it ships.
Is CE marking required for a soda maker?
It depends on the finished product and where it is sold. Mains-powered appliances fall under electrical and electromagnetic compatibility directives, and the obligation sits with whoever places the finished product on the market — which may be you, not the factory. Ask which standards were tested and get the test report; a factory that cannot produce a test report has not tested anything.
How can I tell whether a certificate is genuine?
Every legitimate certificate carries a registration number and an issuing body, and most issuers publish an online register. Ask for the number, then check it on the issuer’s own site instead of trusting a scanned PDF. Also check the scope: a certificate that covers "electrical appliances" is not the same document as one that names soda makers.
When in the project should I ask for these documents?
Before you pay for tooling, not before you ship. If a factory has already run the food-contact and material tests on the platform you are adapting, that saves weeks; if the documents have to be generated for your product, that time belongs in your launch plan. Either way it is cheaper to find out at the quotation stage.
