TALK / MARKET AND TARIFF DISCUSSION
Buyer question

A carbide supplier blames Congolese cobalt export quotas for a price rise. What do the quotas actually say, and what can an edge buyer reasonably conclude about carbide costs from them?

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.

↳ Replying to SENTHAI Editorial Team

Ask for the surcharge basis in writing, with the effective date and review interval. Compare quotes on base price, surcharge and validity together. Keep the supplier’s explanation with the quote. If the explanation cites cobalt, ask which grade and what share, so that you can judge whether the increase matches your product.

↳ Replying to Purchasing perspective

Do not switch grade because of a cobalt headline. A change in binder can affect properties, so any switch should be tested by the supplier and by you. If you consider alternatives, ask for datasheets and trial samples, and keep the results with the purchase record. The aim is a decision based on tests and price together.

↳ Replying to Selection perspective

If carbide costs rise, look at how you use edges before you look at grades: replacement triggers, rotation and impact damage. Records of wear and failures help you argue for or against a change. Keep a reserve of edges so that you are not forced to buy during a price spike.
