Tips to enter the lot number when requesting a C of A or C of O

Sigma

• More important for C of O: enter a "0" if only two numbers are in front of the letter e.g. 62K1064 – you will only find the C of O if you enter 062K1064.

Aldrich

• If you find such a lot number on your label TO09019TO then just enter 09019TO without the first two letters.
• If you find a lot number with a filling-code behind like 05427ES–021 - just enter the lot number 05427ES without the filling-code -021.

Fluka

• Please enter the lot-number without filling code (the part after the dash)If 430588/1-21402 is given on your label then enter only the lot number 430588/1.
• Enter the lot number as a 6-digit string e.g. 049351/1 instead of 49351/1).
