Certificates

Certificates available upon request. Ask in the enquiry about documents for the items you name.

The general position on documents

This site uses one general wording for documents: certificates are available upon request. No list of certificates is published here, and no certificate number, issuing body or validity period is stated for any item. Name the items in the enquiry to receive the documents that apply to them. Document questions depend on the item, the destination and the requirement that applies to the job, and they can only be answered reliably when the items are named in the enquiry.

A buyer who needs a document should therefore name the route, the form and the application in the enquiry, and ask what documents apply to those items. The answer can then be tied to the order, rather than read as a general claim about the whole catalogue. The same approach applies to any third-party record mentioned on this page: it is described as a record, with its source, and questions about what it covers belong in the enquiry.

A third-party listing, described as a record

A third-party listing on qai.org records Tianjin Huayue International Trade Co., Ltd. for the ThermRock Basaltboard product, with related standards listed on that listing. That listing is a third-party record, not a company certificate claim, and this site does not present it as one. A buyer who wants to know what that listing covers for a particular item should ask in the enquiry, naming the item, so that the answer can be checked against the listing itself.

No other document is named on this page. In particular, no homepage image title is reproduced here as a list of documents held, because an image title on its own does not establish what document, if any, applies to a particular order. The enquiry remains the route for every document question on this site.

Questions worth asking in the enquiry

Useful document questions include: which documents apply to the route and form named; whether the documents differ by destination; and what information the supplier needs from the buyer before a document question can be answered. Each of those questions should be tied to named items, since a document that applies to one form may not apply to another. Put the item names first, and the document questions second, so that the reply can follow the same order.

The same discipline applies to quantity, timing and commercial questions. Documents, quantities and timing are all settled for named items in the enquiry, not stated as catalogue facts. An enquiry that follows that order will produce answers that can be checked against the order, which is the only form in which such answers are useful.

How document answers are tied to items

Every document answer on this site is tied to named items, and that tying is what makes the answer useful. A document that applies to one form may not apply to another, and a document that applies in one destination may not apply in another. An enquiry that names the route, the form and the application, and then asks what documents apply to those items, will receive an answer that can be checked against the order. An enquiry that asks about documents without naming items will receive only a general answer, which cannot be checked in the same way.

The same tying applies to the third-party listing described on this page. The listing records a company name and a product name, and questions about what it covers should name the item concerned, so that the answer can be checked against the listing itself. That discipline, items first and documents second, runs through every page on this site, and it is the reason the enquiry form asks for a message that states route, form and application together.
