DRC Cobalt Quotas and Carbide Costs: What Edge Buyers Can and Cannot Conclude

Scenario: a supplier mentions cobalt costs as a reason for a carbide price rise. Direct answer: cobalt export policy in the Democratic Republic of the Congo is real and recorded, but a quota on cobalt does not give you a carbide edge price. Use it as background and ask your supplier how cobalt enters their quote. The figures below are from the policy record as read on 24 October 2026 and may change.

What the IEA policy record says

The policy record is worth reading directly rather than through a supplier summary, because the dates and quantities are what matter.

• On 20 September 2025, the DRC regulator ARECOMS issued Decision 004/ARECOMS/2025, extending a suspension that had been in place since February 2025.
• From 16 October 2025 a quota-based export system applies. The 2026 total is 96,600 tonnes, made up of a base quota and a strategic quota.
• For 2027 the record gives the same total, subject to quarterly adjustments, and says the decision will be reviewed.

Why cobalt may matter to carbide

A carbide supplier’s description of the material, quoted by a recycler, says carbide consists of tungsten carbide grains embedded in a binder phase of cobalt or, less commonly, nickel, with cobalt content generally 5% to 15% and special grades up to 30%. So cobalt is one input to many carbide grades.

What you cannot conclude

An allocation is not a shipment, and the difference matters for lead time.

• The quota is an allocation, not a count of material shipped, and it does not tell you the price of cobalt or of a carbide insert.
• Your edge’s binder content, and how much of its price is cobalt, depend on the grade and supplier.
• One trade article describes a tool maker adding a separate carbide raw-material surcharge; that is one company’s practice, not an industry rule.

Questions for your supplier

Raw-material clauses are where a carbide quote hides its risk. Four questions make the exposure visible.

1. Does your quote include a raw-material surcharge, and how is it calculated? An index-linked surcharge and a fixed price behave very differently over a season.
2. Is it linked to tungsten, cobalt or both, and how often does it change? Cobalt and tungsten do not move together, so the basis matters.
3. What binder does the insert grade use, and in what range? Binder content drives both toughness and exposure to cobalt pricing.
4. How long is the quote valid? A quote that expires in days is a position on price, not a commitment to supply.

Boundary: Facts are dated 24 October 2026 and may change; the quota is not a price and not a shipment count, and nothing here predicts carbide prices.
