How to Request a Useful Silicon Metal Quote
A vague message like “please send price” almost never produces a quote you can act on. Silicon metal is sold against tight chemical specifications, and the number you get back is only as good as the information you send. This guide lists exactly what a supplier needs so your RFQ returns a firm, comparable offer instead of a guess.
1. Information your supplier needs
- Grade / specification – e.g. Silicon Metal 553, 441, 421, 3303, or 99.9% refined. State the exact Fe / Al / Ca limits you require.
- Quantity – total tons and whether it is a one-off or recurring monthly volume.
- Size / particle – lump (e.g. 10–100 mm) or powder (e.g. 0–3 mm, 325 mesh), with tolerance.
- Packing – 1 MT jumbo bag, 25 kg PP bags on pallet, or bulk.
- Destination & Incoterms – FOB / CFR / CIF with discharge port, or EXW from warehouse.
- Target price (optional) – sharing a budget range speeds negotiation.
- Required timeline – when you need the goods and the documents (CO, CIQ, SGS).
2. Typical Silicon Metal specifications
| Grade | Si (min) | Fe (max) | Al (max) | Ca (max) | Common application |
|---|---|---|---|---|---|
| 553 | 98.5% | 0.5% | 0.5% | 0.3% | Aluminium alloy, deoxidation |
| 441 | 99.0% | 0.4% | 0.4% | 0.1% | Aluminium alloy, silicone |
| 421 | 99.1% | 0.4% | 0.2% | 0.1% | Silicone, photovoltaic |
| 3303 | 99.3% | 0.3% | 0.3% | 0.03% | Silicone, photovoltaic |
Note: “553” means Fe≤0.5%, Al≤0.5%, Ca≤0.3%. Always confirm the exact standard (GB, ISO, or customer spec) with your supplier.
3. What a complete quote should include
- Unit price with the named Incoterm and currency.
- Chemical analysis (Fe / Al / Ca / impurities) the lot will meet.
- MOQ and container load (a 20 ft container typically holds 20–27 MT depending on grade and packing).
- Lead time: commonly 7–15 days after deposit for stock grades; 15–30 days for tailored specs.
- Packing details and containerisation method.
- Validity period of the quote and payment terms (T/T, L/C).
4. Common RFQ mistakes to avoid
- Quoting only “silicon metal” without a grade – 553 and 421 differ sharply in price.
- Mixing up silicon metal and ferrosilicon (see our comparison guide).
- Forgetting size: lump and powder are different product lines and prices.
- No destination port – freight can be 10–30% of landed cost.
Frequently Asked Questions
What is the minimum order quantity for silicon metal?
MOQ is normally one 20 ft container, roughly 20–27 MT depending on grade and packing. Smaller trial quantities can sometimes be arranged from stock.
How long is the lead time?
For standard grades in stock, 7–15 days after receipt of deposit. Customised composition or particle size usually needs 15–30 days.
Should I choose 553 or 441?
It depends on your process. 553 is the workhorse grade for most aluminium alloys and general deoxidation; 441 and finer grades (421 / 3303) are used where lower Al / Ca matters, such as silicone and photovoltaic feedstock.
Do you provide samples?
Yes. Small representative samples are usually available (sometimes free, sometimes freight-collect) so you can verify composition before a full order.
Which Incoterms do you offer?
Commonly EXW, FOB, CFR and CIF, with shipment from major Chinese ports such as Tianjin, Qingdao or Dalian.
