How to Write a Titanium Bar RFQ Suppliers Can Actually Quote

Ask a Baoji titanium supplier what slows down or derails an overseas order, and price isn’t the first answer. The most common issue is simpler and more avoidable: buyers send a request that isn’t specific enough to quote accurately. The supplier either has to send several rounds of clarifying questions (slowing everything down) or guesses at the missing details — and guessing is where mismatched shipments happen.

Here’s what a supplier actually needs to give you an accurate, fast quote.

The two fields buyers most often leave vague

Tolerance. “Standard tolerance” isn’t a spec — it varies by mill and by what “standard” means to a given factory. State the actual tolerance you need (e.g., ±0.05mm), or the standard you’re quoting against (ASTM B348 has defined tolerance classes).

Chemical composition requirements. Naming the grade (Gr5 / Ti-6Al-4V) tells a supplier the target alloy, but if you have tighter-than-standard requirements on specific elements (oxygen content for certain fatigue- sensitive applications, for example), that needs to be stated explicitly. “Gr5” alone assumes standard composition limits — if your application needs something tighter, say so up front.

A useful mental model: tolerance is a hardware question, not a skill question

A common misconception is that tight dimensional tolerance comes down to an experienced machinist or an especially careful factory. In practice, tolerance capability is largely determined by the rolling mill itself — its precision, condition, and calibration — not by how many years the operators have been doing the job. When evaluating a supplier’s ability to hit a tight tolerance, the more useful question is “what mill do you run, and what tolerance is it rated for,” not “how experienced is your team.”

This matters for RFQs too: if your tolerance requirement is tight, it’s worth asking directly whether the supplier’s equipment supports it before you’re deep into a quote — rather than finding out after material arrives out of spec.

Minimum information for a quotable RFQ

• Grade (e.g. Gr5 / Ti-6Al-4V) and the standard it should meet (ASTM / AMS)
• Form and dimensions — diameter, length, and tolerance
• Quantity, and whether you need it from stock or can accept a made-to-order lead time (in-stock material can ship in quantities as small as 1kg from some suppliers; custom/non-standard specs typically carry a minimum order — ask what applies to your spec)
• Application — this isn’t just informational. It tells the supplier what certification you’re likely to need (see below), and whether your spec falls into a category that requires additional documentation
• Certification requirements — if you need third-party test reports (SGS or equivalent), say so in the RFQ rather than after the quote

Why this is worth doing properly

A vague RFQ doesn’t just slow down your quote — it shifts risk onto you. When a supplier has to guess at tolerance or composition, the material you receive may be correct by their interpretation and still wrong for your application. A specific, complete RFQ is the cheapest form of quality control available to a buyer, and it costs nothing but a few extra minutes before you send it.
