It depends on the animal it came from. Beef tallow is melted-down beef fat, and it is halal only if the cattle were slaughtered the Islamic way (zabiha). Most commercial tallow comes from ordinary slaughterhouses, so it is best treated as doubtful unless it is halal-certified. There is no pork question here, because it comes from beef. The only question is how the animal was slaughtered. Beef tallow is also the ingredient behind the famous question, "Are McDonald's fries halal?"

The short answer
Beef tallow is melted-down beef fat. Whether it is halal depends on the animal. Fat from cattle slaughtered the zabiha way is halal. Fat from cattle slaughtered in the ordinary commercial way is doubtful according to most scholars. There is no pork question, because it is beef.
Why is beef tallow a "depends" and not simply halal?
Fat from a permitted animal is halal only if that animal was slaughtered the Islamic way. Most commercial beef tallow in the United States comes from ordinary slaughterhouses that do not follow the zabiha method. So unless tallow is halal-certified, it is best treated as doubtful.
What does beef tallow have to do with McDonald's fries?
Beef tallow is behind the question "Are McDonald's fries halal?" McDonald's fried its potatoes in beef tallow until 1990, when it switched to vegetable oil. However, US fries still contain a "natural beef flavor." That is why US fries are treated with caution, while fries in the UK and Canada, which use only plant oil and no beef flavor, are considered halal-suitable.
Where is beef tallow used?
You can find beef tallow in some fried foods, pastries and refried beans. Some restaurant chains have also started frying in beef tallow again. Outside of food, it is used in candles and soap. On a label, it may appear as "beef tallow" or "beef fat," or it may be hidden inside "natural flavors."
How can you check for halal beef tallow?
- A halal or zabiha certificate is the only confirmation.
- Unnamed "beef tallow" in a popular product is doubtful.
- Watch for "natural beef flavor," which raises the same question about where the beef came from.
What can you use instead of beef tallow?
Use vegetable oils, or halal-certified beef tallow from zabiha cattle when a recipe really needs it.

Not since 1990. They are cooked in vegetable oil, but US fries still contain a beef-based natural flavor, which is why they are treated with caution in the United States.

No. It is beef fat. The question is not pork. The question is whether the beef was slaughtered the Islamic way.
