Sending samples

Sending lubricant and operating fluid samples to OELCHECK

In each all-inclusive analysis kit, you will find a sample bottle along with a pre-addressed envelope, a Sample Information Form and a UPS return label for sending liquid or solid samples.
The envelope is made of oil-tight, recyclable plastic. Through the self-adhesive seal, the envelope leakproof. The Sample Information Form is placed in the external window pocket to ensure that it is not soiled by the sample bottle or potential oil stains.


All customers in Germany receive a UPS return label as part of the all-inclusive analysis kit. It entitles the customer to send samples to OELCHECK free of charge within Germany.

The bottom of the Sample Information Form, which is detached on the perforated line, is your sample reference, on the back of which you write down your UPS Tracking #. The Unit ID and components can be given on the front. On the sample reference, you will also find your lab number. The noted UPS number and lab number can help you track your samples and their status more easily.
Stick the UPS return on the OELCHECK address on the front of the envelope.

CAUTION: Please do not stick anything over the field "Sample from" or the window pocket containing the Sample Information Form.
Once your delivery is ready, register it to be picked up by UPS, stating the UPS Tracking #, or send it from a UPS drop off point in Germany.
Contact OELCHECK (Tel. +49 8034-9047-250) if you would like further information on overseas UPS sample delivery prices.

Sending oil samples, coolant samples, grease samples and fuel samples

Protecting the environment is important to us. This is why all of our equipment is recyclable. It’s also possible for you to contribute to this by combining your deliveries. You can send up to four sample bottles in one OELCHECK envelope. The delivery box in which you have received your all-inclusive analysis kit can fit up to eight sample bottles. If you want to send even more samples on the same day, please use your own delivery box. 

Time and again, questions arise at the post office, courier services or shipping companies in connection with the contents of the items to be transported The delivery can easily be classified as suspicious and may not be delivered, particularly when the content is liquid. 

If problems occur regarding this, please note the following:

  • Declare oil samples as new or used oils, not waste oils. As waste oils, they might be considered dangerous goods under certain circumstances. Lubricants are only considered waste oils when they are no longer suited for their original intended use. The lubricant or operating fluid samples you usually send come from systems where the liquids can remain in use.
  • Where applicable, give a flash point of over 200 °C. The limit value, which is a minimum according to the UN dangerous goods classification, is 61 °C. Standard hydraulic, engine and gear oils have a flash point of over 200 °C. Diesel and heating oil, which mostly have flash points of over 65 °C, are not dangerous goods either.
  • Refer to the "limited quantities" rule. As the lubricant samples are in low quantities of less than 100 ml, these goods are exempt from transport provisions for road and rail. Quantity restrictions in accordance with the ADR/RID (road/rail) and IATA (air) provisions only apply for the delivery of samples such as petrol. However, these only define the sample as dangerous at quantities of over one liter.
  • Please only use the sample bottles that we provided with our all-inclusive analysis kits. The delivery of lubricant samples in bottles, which are intended to store food, is prohibited in accordance with §8, section 7 of the German Ordinance on Hazardous Substances.
  • Although you are not required to include a safety data sheet due to the high flash point and minimal quantity, you should procure a copy of the material safety data sheet (MSDS) in case of inqueries. You receive this multi-page document, which also contains instructions on storage and transportation, with the oil delivery from your lubricant manufacturer. The document is also often available for download online.
  • When sending oil samples by air, please note that a delivery is often only possible if the staff member responsible is proven to have completed a IATA training.
  • New and used greases are not deemed dangerous goods in accordance with UN provisions. There are no restrictions or quantity limits for their transport by road or air.

In order to avoid customs issues when sending samples from overseas, you should use the following wording in your customs documentation and the pro forma invoice.

The samples are not subject to taxation under german §1 Energy Tax Act because the content of the lubricant samples
is not intended for heating or as fuel.
