I've been working in the suppl chain world at the same company for 10 years and was recently made supply chain manager. The past 2 months is the first time I've seen surcharges being added to invoices instead of a standard price increase and all the raw material companies are siting "geopolitical issues" as their reason. I don't doubt that for obvious reasons but I'm curious and trying to learn if this was done in the past anytime there was a war or is the surcharge tactic something new going on when markets are volatile? Just looking for advice from anyone who has been around the block for a few decades lol.
