Proposal to amend frequency of antimony ddp China price: pricing notice

Fastmarkets proposes to amend the frequency of the publication of its price assessment for MB-SB-0003 Antimony MMTA standard grade II, ddp China, to monthly from weekly.

Fastmarkets selects the frequency of publication of a market assessment after considering the number of data points (deals, bids, offers, deals heard and assessments) that it can reasonably expect to collect on a consistent basis over the selected period to support the price assessment process.

This proposal follows preliminary discussions with the market as well as internal meetings to review relevant Fastmarkets’ data, which suggest lower spot liquidity, price volatility, and data usage recently.

The proposed new specifications are listed below, with the proposed amendment of price frequency in italics:

MB-SB-0003 Antimony MMTA standard grade II, ddp China, yuan/tonne
Quality: Ingot. MMTA standard Grade II. Sb 99.65% min, As 0.1% max, Pb 0.2% max, Se 0.002% max, Cd 0.002% max, Sn 0.005% max, Te 0.005% max, Bi 0.01% max, Cu 0.02% max, Fe 0.02% max 
Quantity: 1 tonne 
Location: Delivered duty paid China 
Unit: CNY/tonne 
Payment terms: Cash

The price is a part of the Fastmarkets’ minor metals package.

The consultation period for this proposed amendment starts from Tuesday April 8 and will end on Thursday May 8. The amendment will then take place, subject to market feedback, with the first assessment on a monthly frequency on Friday May 30.
