Yes, "paste" items—such as toothpaste, hair paste, or food pastes like pesto or tomato paste—are fully allowed in checked baggage without any volume restrictions. While these items are strictly limited in carry-on bags by the TSA's 3-1-1 rule (meaning they must be in containers of 3.4 ounces or less and fit in a single quart-sized bag), these rules do not apply to luggage that is stowed in the cargo hold of the plane. You can pack a giant, family-sized tube of toothpaste or several large jars of peanut butter in your checked suitcase without any issue from security. However, it is highly recommended to pack these items carefully to prevent a mess. The change in air pressure in the cargo hold can sometimes cause tubes to expand and leak, or jars to "pop" their seals. To avoid "paste-proofing" your wardrobe, you should place these items inside a sealed Ziploc bag or a leak-proof toiletry kit. For food items like curry paste or spreads, ensure they are in their original packaging and check the customs regulations of your destination country, as some places have strict rules about importing certain food products, even if the "consistency" of the item is cleared by airport security.
