Walmart sent a letter to President Donald Trump and the US trade representative about two weeks ago about downsides of the US's proposed tariffs on Chinese goods.

Trump has gone ahead with the tariffs anyway.

From a July list proposing more than 6,000 goods that could be subject to the tariffs, Walmart identified 31 that it said could cause the most harm to its business and customers.

Five of the high-concern goods were dropped from the final list, released on Monday, but the rest are set to get hit with tariffs.

The 26 goods on Walmart's list include air conditioners, dog food, and Christmas lights. Check out the full list below.

Walmart's stern warning to President Donald Trump about the trade war with China appeared to go unheard, and now some key goods sold by the retail giant could see serious trouble.

In a letter to Trump and US Trade Representative Robert Lighthizer sent about two weeks ago, Walmart warned that the latest tariffs on $200 billion worth of Chinese goods could cause major disruptions to its supply chain and price increases for its shoppers.

"As the largest retailer in the United States and a major buyer of US manufactured goods, we are very concerned about the impacts these tariffs would have on our business, our customers, our suppliers, and the US economy as a whole," Sarah Thorn, Walmart's senior director for global government affairs, said in the letter, seen by Business Insider.

She continued: "This round of tariffs could impact a significant number of common consumer items that are not easily replaceable."

The new set of tariffs, which are taxes on imports, raised alarms for Walmart because many products on the list of potential targets included, for the first time, consumer goods. Previous rounds have focused on industrial goods like bulldozers and chemicals.

Included in the letter was a list of goods that Walmart sources from China that could be subject to the new tariffs.

Walmart's "worry list" was based on the Office of the US Trade Representative's initial list in July of more than 6,000 Chinese goods considered for tariffs. There were five items Walmart highlighted that were dropped from the final list, released Monday, including some electronics, child seats and high chairs, patio furniture, and car seats.

The USTR provided limited details as to why those items were removed, but a senior administration official said Monday that the USTR considered the availability of non-Chinese versions of the goods and the statements from businesses when making the decision.

Twenty-six types of goods on Walmart's "worry list" are on the final tariff list. They range from wood furniture and mandarin oranges to HDMI cables.
