Real case

Kitchen equipment without CE marking, stopped at the port of Hamburg

A restaurant owner orders professional kitchen equipment directly from China. At the port of Hamburg, customs inspects it: no CE marking, no labels on the devices, no manual with safety instructions. Two expensive options remain: have the equipment disposed of at the port or ship it back at his own cost, without knowing whether the manufacturer will take it back. It never reached his kitchen. He only came to us afterwards.

What we would have found beforehandPackage L shows which marking and which documents are required. The inspection before shipment would have spotted the missing CE marking on the devices.

What can go wrong without a check

Example figures

Your deposit goes to a company that does not exist as stated

€2,400 deposit lost

Check S: the bank account does not belong to the company.

The “manufacturer” is only a trader and adds 30 %

€2,400 too much on €8,000 of goods

Check S spots the trader, package M finds real manufacturers.

2,000 pieces arrive, every tenth is defective

Goods unsellable, returns hardly possible

Inspection before shipment.

Market surveillance finds missing documents after the goods are already on sale

Product taken off the market, recall, fines possible

Package L: documents checked beforehand.

Untested substances in products that touch skin or food

Skin rash for your customer, liability, recall

Package L: are there test reports, for example on REACH or food contact?

What we find beforehand

If your check is late, the price is waived.

German quality inspection to ISO 2859‑1

We do not inspect by gut feeling but by the international standard for sampling inspections: precise, traceable and with a photo report.

  • At the factory before shipment, anywhere in China at the same price
  • Appearance, dimensions, function, marking and packaging
  • Photo report in English or German within 24 to 48 hours
€349net
Book inspection, €349
Sample report: Quality inspection

No laboratory analysis of substances. Package L clarifies whether lab reports exist.

Sample photosSample photosSample photosSample photos
Sample photos

What does ISO 2859‑1 mean?

ISO 2859‑1 is the international standard for sampling. Instead of checking every piece, we draw a set number of pieces according to fixed rules and count the defects. The defect limits are called AQL: 0 for critical defects (dangerous), 2.5 for major defects (goods hardly sellable), 4.0 for minor defects (small cosmetic flaws). We inspect at level II, the usual standard.

Example: for 1,000 pieces we inspect 80 pieces. The shipment passes with at most 5 major and 7 minor defects. A single critical defect means it fails.
