Christie’s has once again raised its buyer’s premium, this time adjusting rates for low-end purchases.

A new buyer’s premium rate of 25 percent is to be introduced at all sites as of September 1 with the following thresholds: United States (New York City and Los Angeles), $20,000; King Street and South Kensington, £10,000; Paris, Amsterdam, Milan and Spain, 5,000 euros; Geneva, 20,000 Swiss francs; Hong Kong, 150,000 Hong Kong dollars; Dubai and Tel Aviv, $20,000.

The current rates for prices above these thresholds remain unchanged at all Christie’s sites †20 percent of the final bid price of each lot up to and including $500,000 and 12 percent on any amount above that.
