Dangerous Goods Classification by Substance or UN Number

omnial/x402-dangerous-goods-classify

Given a substance name or UN number, returns its dangerous-goods classification: hazard class and division, packing group, proper shipping name, hazard labels, special handling provisions, marine-pollutant and limited-quantity status, and an Emergency Response Guidebook guide number. When the substance is not recognized, returns a no-match result with guidance on how to retry instead of an error.
