With a common MOQ of 10 tons, buyers can expect to commit to significant volume, making this category ideal for established supply chains rather than small-scale testing. The global spread of top suppliers across the U.S., India, Germany, Afghanistan, and Spain offers diverse sourcing options with different price points and quality profiles, so buyers can match their needs to specific regions. Combined with a wide reference price range—from $1,600 to $56,000 per ton—buyers must carefully evaluate origin, processing, and trade terms to avoid overpaying and ensure cost efficiency.
