Antimony Ore Supplier in Pakistan: What to Check Before You Order

Before you order antimony ore from any supplier in Pakistan, check three things: how the lot was sampled and analysed, what the material actually is (crushed ore or concentrate), and who inspects it at loading. Get those right and most disputes disappear. Get them wrong and you're arguing about numbers after the container has already sailed.

Here's a working checklist for buyers — smelters, trioxide producers, and ore traders — sourcing from Pakistan.

What to check in an antimony ore assay

The headline number is Sb (antimony) content, reported as a percentage. That's what you're buying. But the assay alone doesn't tell you whether the figure is reliable — the sampling behind it does.

Ask who took the sample and how. A grab sample off the top of a pile means almost nothing. A properly composited sample from the crushed lot, split down and sealed, is what a certificate should be based on.

At GBX Resources each lot is sampled and analysed by SGS Pakistan, and the material is sold against that SGS certificate of analysis. You can also test a sample in your own laboratory before you commit, and appoint SGS or your own inspector at loading. That's the normal way to keep both sides honest.

What to look for on the certificate:

• Sb percentage and the analytical method used
• Moisture content (you pay on dry weight, so this matters)
• Deleterious elements — arsenic (As) is the big one for antimony, plus lead, and sometimes mercury
• The date and the lot or sample reference so the certificate ties to the actual material

Arsenic is the penalty element most trioxide and metal producers watch. High As raises your processing cost and can breach environmental limits at your end. So agree an As threshold and a penalty scale in writing before you order — not after.

One more thing. Confirm whether you're buying crushed ore or flotation concentrate. These are different products with different Sb ranges and different prices. GBX sells crushed ore, crushed to your size range — not concentrate. If a spec sheet quotes a very high Sb figure, ask directly which one it is.

You can see how GBX describes the material on the antimony ore page.

HS code and how antimony ore is classified

Antimony ores and concentrates fall under HS heading 2617 — specifically 2617.10 in most tariff schedules. Your customs broker will confirm the exact national suffix for your country, and you should check that against your import permit if antimony is controlled where you are.

Why it matters: the HS code drives duty, any import licensing, and how the shipment is declared. Getting it wrong causes delays at your port, not the loading port. Confirm it early with your broker.

Antimony is on several countries' critical or strategic minerals lists, and some jurisdictions apply export or import controls. That's a moving target and depends entirely on where you sit — so verify the current position with your own authorities rather than trusting a general claim.

Packing, weighing and shipment terms

Crushed ore for export usually moves in bulk bags (jumbo/FIBC bags) stuffed into containers, or as breakbulk depending on volume and route. The packing method affects moisture protection and weighing, so agree it up front.

On Incoterms, GBX quotes FOB Karachi, with CFR on request. Quick reminder of what that means for you:

CFR does not mean insured. Under CFR the seller pays freight but risk still passes at the loading port, so arrange your own marine cargo insurance either way. Honestly, a lot of first-time buyers assume CFR covers them for loss at sea — it doesn't.

Minerals are supplied to order. Availability and the shipment window get confirmed on enquiry, so tell the supplier your target quantity and dates when you first make contact. Don't assume anything is sitting on a dock waiting.

Inspection and weight at loading

This is where you protect your money. Independent inspection at the point of loading gives you an agreed weight and an agreed sample before the ore leaves Pakistan.

Your options with GBX:

• Rely on the SGS Pakistan certificate of analysis that each lot is sold against
• Test your own sample in your own lab beforehand
• Appoint SGS or your own inspector to attend loading

A sound inspection scope covers weight (draft survey or weighbridge, depending on how it ships), sampling and moisture determination, and sealing of samples for both parties. If a supplier resists third-party inspection, treat that as a warning sign. A serious antimony ore exporter in Pakistan won't blink at SGS attending loading.

Documents you should expect

For an FOB or CFR shipment out of Karachi, the usual document set is:

• Commercial invoice
• Packing list (with bag count and weights)
• SGS certificate of analysis
• Bill of lading
• Certificate of origin
• Any export documentation required on the Pakistan side

Check what your own bank and customs need before you agree payment terms. If you're opening a letter of credit, the L/C wording has to match this document set exactly — one mismatched field and the bank can reject the presentation. Line it up with your supplier before the L/C is issued, not after.

How to place an order

Here's the here's-the-thing part: the buyers who have the smoothest first order are the ones who send a clear enquiry. Not "do you have antimony ore" — but the specifics.

When you contact a supplier, include:

• Target Sb range and your maximum arsenic tolerance
• Quantity and your preferred shipment window
• Crush size you need
• FOB Karachi or CFR to your named port
• Any inspection you want at loading

That lets the supplier confirm availability and give you a real quote instead of a vague reply.
