I buy mostly paper and plastic packaging. When factoring in tariffs and shipping costs, it's generally cheaper in China like 70% of the time and there are more suppliers in China (so it's easier to find them on Alibaba). It's generally harder to find the American suppliers and there's a wider variance in price. It could be there are two American options and 25 Chinese options. One American company could be the cheapest and the other could be the most expensive. The Chinese companies tend to have lower variance in pricing.
