Certificate of Analysis
Assay, heavy metals, microbiology, moisture, ash, lot number, manufacturing and report dates. English.
Home · Quality
What arrives with the goods.
Most of the work in this trade is paperwork that fails an audit. This page is what we issue, and what we do when a lot does not pass.
Documentation
What ships with every lot, under our seal.
The number on the drum, the number on the certificate and the number on the invoice are the same number.
Specification sheet
The limits the lot was released against, for registration and for your customer's file. English.
Analytical method
The method used for each test item, item by item. English and Chinese, because the laboratory reads Chinese.
Certificate of Origin
Issued for customs clearance. English.
Material Safety Data Sheet
On request. Supplied with the quotation when the product requires it.
For blends
The Certificate of Analysis additionally carries blend uniformity and content distribution. A premix certificate is not the same document as a single-material one, and we do not send one in place of the other.
Written on our side
The certificate is issued under our name and our seal.
Not forwarded as a PDF from a plant. The analytical methods are compiled by us, which is why they are bilingual and why we can explain any line on the sheet when your QA team asks.
When something is wrong, the call comes to us, not to a plant office that has never heard of your order.
Lot numbering and retest
- Lot number AIX followed by the manufacturing date in YYMMDD. The number on the drum, the certificate and the invoice are the same number.
- Report date Issued six to seven days after manufacture, once the analytical work is complete.
- Retest date Two years from manufacture, less one day, stated on the certificate.
Independent testing
A report from a laboratory that is not the manufacturer.
Where your market or your customer requires it, testing is arranged through a government-accredited laboratory in Changsha. Give us the limits, we send the sample, and the report travels with the lot.
This is arranged per order. It is not a standing certificate, and we do not describe it as one.
Halal
Certification is held on individual items, not across the whole range.
For blends it is filed per formula against your specification, and the carrier we use is chosen with that in mind.
Tell us at the quotation stage if your market requires it. We will tell you before you ask whether the item you want is covered.
If your specification cannot be met, we say so before the order, and tell you what can be met instead. That is cheaper for both of us than a failed incoming inspection.
Ask
Send the limits. We will tell you what holds.
If a specification keeps failing on arrival, send it even if we never trade — there is a good chance we can tell you why.
