Tungsten Stays on a High Plateau as the Renminbi Firms and the Tariff Stack Grows

The short version

• Tungsten concentrate is holding a historically high plateau. Chinese black tungsten concentrate (WO₃ ≥ 65%) was reported at RMB 406,900 per tonne on 17 September 2026, roughly 197.7% above the same period in 2024 — but it has moved sideways rather than upward through the third quarter.
• Ammonium paratungstate (APT) is drifting marginally weaker at RMB 594,000–600,000 per tonne for national zero-grade material, with September long-term contract prices anchored at RMB 600,000.
• The renminbi has firmed to 6.6995 per US dollar, about 2.9% stronger than a 6.90 reference rate — a direct, quantifiable headwind for anyone pricing in US dollars.
• The US tariff stack on Chinese tools and hardware still resolves to roughly 64% at category level, and the shape of it matters as much as the total: rates differ between non-powered hand tools and powered tools.
• Mexico’s tariff on 1,463 product lines from non-FTA countries has been in force since 1 January 2026, raising landed costs across a wide range of imported hardware.

1. Tungsten: a high plateau, not a spike

1.1 Reported price levels

Long-term contract anchors (first half of September, 13% VAT included) — Zhangyuan Tungsten: black tungsten concentrate (WO₃ ≥ 55%) RMB 413,000 per standard tonne; scheelite concentrate (WO₃ ≥ 55%) RMB 412,000 per standard tonne; ammonium paratungstate (national zero-grade) RMB 600,000 per tonne.

Chart: the same squeeze viewed from two angles — domestic concentrate year on year, and Rotterdam APT against mid-2024. Data as published by the sources listed below.

1.2 What the shape of the curve says

The pattern through 2026 is a spike, a correction, and then a plateau:

1. Q1 — sharp advance to a historic high.
2. Q2 — a significant pullback, with a sequential decline reported at 14.19%.
3. Q3 — high-level, narrow-range oscillation. Current levels sit well below the March peak but remain close to double their level two years ago.

Three supports hold the plateau: domestic mining quota control, which limits how fast supply can grow; a strategic-metal premium; and a cost line plus long-term contract floor that producers defend. Two catalysts point the other way up — the September–October peak season, and new demand from AI PCB drill needles and tungsten hexafluoride (WF₆).

Institutional commentary is consistent and deliberately hedged: near-term prices are expected to stay range-bound with a soft bias, and a genuine recovery needs to be confirmed by real transaction volumes rather than by sentiment. China Tungsten and Hightech has stated publicly that it cannot forecast tungsten prices precisely, and the wider industry view remains one of a tightly balanced supply and demand structure.

What we are not saying: none of the numbers above is a quotation, and none of them should be treated as a forward price. They are published third-party reference points, reproduced with their original dates so that readers can judge how current they are.

2. Currency: the quiet second squeeze

2.1 Why this matters more than it looks

For a supplier who quotes in US dollars but buys materials, labour, and energy in renminbi, a firmer renminbi compresses the renminbi value of every dollar of revenue — with no change to the invoice price the buyer sees. Around a 0.20 move on USD/CNY translates to roughly 2.9% less renminbi per dollar earned.

The practical consequence for both sides of a transaction is the same: without an explicit currency clause, the FX exposure sits entirely with the supplier, and it grows quietly until it becomes a pricing dispute.

2.2 Practical responses

• Re-base open quotations to the current rate before they are issued, and state the rate and date they were built on.
• Add an FX clause with a defined trigger — for example, a re-pricing right if USD/CNY moves beyond an agreed band.
• Settle on an index for the material leg and a rate reference for the currency leg, so that a future move can be discussed with data rather than with opinions.

3. Tariffs: two markets, two different problems

3.1 United States

Chart: how the individual layers resolve into an effective category-level rate. Rates differ per HS code; the approximately 64% figure is a third-party category-level calculation.

Three points deserve emphasis:

• Powered tools are classified differently. Tools with electric or pneumatic motors generally fall under HS Chapters 84/85, with a different base rate and different Section 232 exposure from non-powered hand tools. A single blended rate cannot be applied across a catalogue of drill bits, burrs, mounted points, sockets, and bits — rates must be checked SKU by SKU.
• Origin is determined by substantial transformation, not by the last port of shipment. Repacking or relabelling in a third country does not change Chinese origin.
• Policy risk remains live. Executive Order 14389 (February 2026) and the Section 122 appeal mean the effective picture can shift again within a contract cycle.

3.2 Mexico

Mexico’s Chamber of Deputies approved the new tariff bill 281 to 24 on 10 December 2025, imposing additional duties of 10% to 50% (with many lines moving to 35%) on 1,463 product lines originating in countries without a free trade agreement — including China, India, and Vietnam. It took effect on 1 January 2026 and has been written into the General Import and Export Tax Law.

For buyers in that market the arithmetic is straightforward: landed cost rises at the border, and programmes with thin margins feel it first. Compliance-based mitigations exist — IMMEX or PROSEC treatment where goods are destined for re-export, and USMCA origin paths where the rules are genuinely met — but each requires its own verification and none should be promised casually.

5. What this means for buyers and suppliers

1. Fix the material leg to an index, not to a memory. Tungsten has moved by more than 190% year on year. Cost formulas that reference a fixed historical price will fail; formulas that reference APT or concentrate indices with a stated reset period will not.
2. Treat currency as a line item. A 2.9% move on USD/CNY is larger than most negotiated annual price concessions. Put a rate reference and a trigger band into the contract.
3. Verify HS classification before, not after, the quote. The difference between a 4% base duty and a steel-content Section 232 layer is a real number, and it is per SKU.
4. Check origin rules honestly. Repacking does not change origin; misstatements at the border create exposure far larger than the duty saved.
5. Buy Q4 peak-season volume earlier. When supply is quota-constrained and prices oscillate in a narrow band, lead time becomes the cheapest hedge available.
6. Ask for the date on every price. A tungsten or FX number without a date attached cannot be used in a negotiation — by either side.

6. Data gaps in this issue

Stated plainly, so that readers can weigh the above:

1. Rotterdam APT spot price for this week — only the May 2026 level of approximately USD 3,000/mtu and a September description were available; no precise current print was obtained.
2. Competitor pricing below the surface — no public price-increase notices were found for IRWIN or KENDO. That does not mean no channel-level adjustments were made.
3. Milwaukee new-product full SKU list and pricing — sourced from trade media and official social channels; not individually verified.
4. Per-HS effective US duty rates — the approximately 64% figure is a third-party category-level calculation; actual rates for any given product must be verified against its own HS code.
5. KENDO — no usable public information retrieved this period.
