As the private label of Costco, the number one membership store in the United States, Kirkland Signature has always had no shortage of fans. This supermarket brand has always been known for its high quality and excellent value for money, and canned tuna is one of the most popular products, with a price that is only slightly higher than the average tuna shelf brand, but it is rated as one of the top competitors in the market.
 
Kirkland Signature's canned tuna is supplied by Bumble Bee, one of the top three canned tuna brands in the United States, but Bumble Bee's own brand has gone the mass market route and won at a low price, while the products supplied to Kirkland Signature have been reborn as the top commodity in the market.
 
Kirkland Signature has only one type of canned tuna, white-fleshed tuna. The tuna is made from albacore tuna caught in the Indian Ocean, processed in Mauritius and canned in the United States, with 100% traceability of the raw fish. The product has a net weight of 7 ounces (198g) per can, which is higher than most similar products, and the weight of the solids after draining the liquid is 153g, which is a very high proportion of fish. The fish meat has no heavy fishy smell, the meat is full and complete, the color is white, it is solid and solid, the texture is firm, the flavor is mild, and the taste is woody. For consumers who prefer a more simple taste, the Kirkland Signature is an ideal choice. Kirkland Signature's white-fleshed tuna has received rave reviews since its release, but the quality has declined slightly in recent years, and impurities such as black-gray mucous membranes and blood clots can occasionally be seen in the fish, which greatly affects the taste of eating.
 
At present, there is no official purchase channel for Kirkland Signature's canned tuna in China. Although Costco's overseas flagship store in Chinese mainland has been launched, it unfortunately does not supply Kirkland's tuna products, and consumers in Chinese mainland still need to shop or purchase on behalf of others. Kirkland Signature's canned white-fleshed tuna is usually sold in eight 7-ounce cans, with an average price of about 20 yuan, which is competitive enough in price and quantity compared to Wild Planet and American Tuna, and the cost performance is outstanding.
