Frequently Asked Questions

General FAQs

Who Is CHIN-SU?

CHIN-SU is a Vietnamese food and condiment brand owned by Masan Consumer Holdings, part of the Masan Group. Most people know us for hot sauce, fish sauce, and soy sauce. But CHIN-SU has grown into a full food ecosystem that includes seasoning granules, mayonnaise, instant noodles, Pho, vermicelli, and frozen foods. Every product in the lineup focuses on one thing: giving your everyday meals more flavor with less effort.

The brand launched in 2002 in Vietnam. 24 years later, CHIN-SU leads the chili sauce category in Vietnam with over 60% market share and ships to the United States, Japan, South Korea, and Australia. What started as a single condiment for Vietnamese home kitchens now sits on tables across four continents.

How Long Has CHIN-SU Been Around?

CHIN-SU entered the market in 2002 and has been operating for 24 years as of 2026. The brand started as a domestic condiment product in Vietnam. It grew into one of the country's leading seasoning brands and now exports to international markets, including the U.S., Japan, South Korea, and Australia.

What Makes CHIN-SU Different from Other Hot Sauce Brands?

CHIN-SU stands apart through flavor balance rather than heat alone. Most hot sauces push one note, whether that's acidity or raw spice. CHIN-SU blends four: spicy, sour, salty, and a gentle sweetness that rounds out the finish. That four-note harmony means the sauce works with a dish instead of overpowering it.

Three things drive that difference. The chili pepper base comes from Ớt Chỉ Thiên (Vietnamese Bird's Eye Chili), harvested at peak ripeness and naturally fermented with fresh garlic. The flavor profile hits your palate in layers, not all at once. And it's built for versatility. You can dip spring rolls in it, stir it into a simmering broth, or use it as a marinade glaze for grilled meats without altering the dish's original flavor structure.

Is CHIN-SU a Vietnamese Brand?

Yes, CHIN-SU is a 100% Vietnamese brand. We were developed and managed by Masan Consumer, one of the largest consumer goods (FMCG) companies in Vietnam. The entire supply chain, from flavor research and domestic agricultural sourcing to production, carries Vietnamese culinary heritage through every step.

Product Questions

What Products Does CHIN-SU Offer?

CHIN-SU produces chili sauces and fish sauces designed for different cooking styles and flavor needs. The current product lineup includes:

Does CHIN-SU Contain MSG?

Yes, CHIN-SU chili sauce contains Monosodium Glutamate (MSG, E621), as well as Disodium Guanylate (E627) and Disodium Inosinate (E631). These flavor enhancers deliver the savory umami taste that defines the sauce's profile.

Here's something worth knowing: the FDA classifies MSG as a safe, plant-derived ingredient produced through fermentation. It contains roughly two-thirds as much sodium as regular table salt. The outdated myths about MSG don't hold up against decades of food safety research, and we're proud to support fact-based conversation about this ingredient.

Is CHIN-SU Gluten-Free?

CHIN-SU chili sauce does not contain wheat or gluten-based grains. The product uses modified starch (E1422) as a thickener instead. International distributors in the U.S. and Europe commonly classify CHIN-SU chili sauce as "Gluten-Free."

If you have celiac disease or a diagnosed gluten sensitivity, always check the label on your specific bottle. Manufacturing processes can differ by production batch, and the packaging label remains the most reliable reference.

Is CHIN-SU Vegan?

The original CHIN-SU chili sauce line is vegan. Its ingredient list is entirely plant-based: chili peppers, garlic, tomato, sugar, salt, and flavor enhancers. No animal extracts, dairy, or seafood derivatives are used in the formula.

One distinction matters here: CHIN-SU fish sauce is made from anchovies and is not vegan. The chili sauce and fish sauce lines are separate products with different ingredient bases. If you follow a plant-based diet, the chili sauce works for you. The fish sauce does not.

What Are the Main Ingredients in CHIN-SU Hot Sauce?

CHIN-SU chili sauce is built on water, sugar, chili peppers at 110 g/kg (3.9 oz/2.2 lb), salt, thickener (E1422), garlic, and tomato concentrate. The full formulation also includes dextrose, maltodextrin, flavor enhancers (E621, E620, E635), acidity regulators (E260, E330), stabilizer (E415), preservatives (E211, E202), mixed spices, artificial sweeteners (acesulfame potassium, aspartame), synthetic flavoring, synthetic coloring (sunset yellow FCF, ponceau 4R), antioxidants (E223, E221, E300), wasabi powder, and sulfites.

The chili peppers used are celestial chili, harvested when fully red-ripe to preserve their natural color and characteristic pungency of Vietnamese-grown peppers.

How Spicy Is CHIN-SU Hot Sauce on the Scoville Scale?

CHIN-SU chili sauce measures an estimated 1,000 to 2,500 SHU (Scoville Heat Units). That puts it in the mild-to-medium heat range, roughly equal to or slightly below standard Sriracha sauce. The design intent isn't to burn. It's to build balanced flavor across four registers (spicy, sour, salty, sweet) while still giving your palate a noticeable kick.

For reference, jalapeño peppers measure 2,500–8,000 SHU, and Tabasco Original sits around 2,500–5,000 SHU. CHIN-SU lands at the approachable end of that spectrum.

What Peppers Are Used in CHIN-SU Chili Sauce?

CHIN-SU uses celestial chili as its core pepper variety. These peppers are harvested at the red-ripe stage, which gives the sauce both its natural color and its sharp, pungent heat. Bird's Eye Chili is one of the most widely cultivated pepper varieties in Vietnam, and its flavor profile carries the warmth and intensity that defines Vietnamese condiment cooking.

What Is CHIN-SU Sriracha for Pho?

CHIN-SU Sriracha for Pho is a fermented chili sauce made for Vietnamese noodle soups. It's formulated to dissolve into hot broth, whether that's Pho, Bún Bò Huế (spicy beef noodle soup), or Hủ Tiếu (pork noodle soup). The sauce combines fermented celestial chili with whole fresh garlic cloves, producing a natural tartness and a slow-building heat that blends into bone broth without breaking its flavor structure.

Why a separate product for soup? Standard chili sauces tend to sit on top of broth rather than integrating into it. This Sriracha line was engineered to disperse evenly, so every spoonful delivers consistent heat rather than a fiery bite followed by a bland one.

Does CHIN-SU Make Fish Sauce?

Yes, CHIN-SU is one of the largest fish sauce producers in Vietnam. The brand operates industrial-scale fermentation barrel houses in Phu Quoc, Phan Thiet, and Hau Giang, processing over 26,000 tons (approximately 57.3 million pounds) of fish per year. That output supplies both the domestic Vietnamese market and international export channels.

CHIN-SU fish sauce starts with fresh anchovies sourced from the fishing grounds of Kien Giang, Phu Quoc, and Phan Thiet. The fish is mixed with refined sea salt at a 3:1 fish-to-salt ratio and fermented naturally in large wooden barrels. This process extracts amino-acid-rich fish sauce concentrate, which then passes through filtration membranes and a closed-loop pasteurization line before bottling.

What Types of CHIN-SU Fish Sauce Are Available?

CHIN-SU offers five distinct fish sauce lines, each designed for a specific use case.

Is CHIN-SU Fish Sauce Made from Anchovies?

Yes, the core ingredient in CHIN-SU fish sauce is fresh anchovies. These are sourced directly from the fishing grounds of Kien Giang, Phu Quoc, and Phan Thiet. After passing quality inspection, the anchovies are mixed with refined sea salt at a 3:1 ratio and aged naturally in large fermentation barrels. That microbial fermentation process extracts an amino acid-dense concentrate before it goes through filtration and sealed pasteurization.

Which CHIN-SU Product Is Best for Pho?

CHIN-SU Sriracha for Pho is the strongest match for noodle soups. The formula was developed with fermented garlic and celestial chili peppers specifically to blend into bone broth. It gives you natural tartness and building heat that integrates into the soup rather than floating on top. Your bowl stays balanced from the first spoonful to the last.

Which CHIN-SU Product Is Best for Grilling or Dipping?

The best product depends on how you're using it.

For dipping, CHIN-SU Chili Sauce (the original line) is the go-to choice for fried foods, spring rolls, and quick snacks. Its spicy-sour-salty-sweet balance works as a standalone condiment. For seafood or boiled meats, CHIN-SU Fish Sauce Salmon or the Sweet and Sour line delivers a lighter, more nuanced dipping experience with adjusted saltiness.

For grilling marinades, combine soy sauce with CHIN-SU Chili Sauce. The soy sauce provides natural color and deep umami flavor. The chili sauce acts as a binding agent, creating a thick, sticky glaze on the meat surface that caramelizes under heat. That combination gives grilled proteins an amber crust and layered flavor you won't get from either ingredient alone.

Storage and Shelf Life

How Should I Store CHIN-SU Products?

Keep CHIN-SU products in a cool, dry area away from direct sunlight and heat sources like stovetops, ovens, or microwaves. Close the cap tight after every use. That seal blocks oxygen and outside contaminants from reaching the sauce, which slows oxidation and preserves flavor stability.

Does CHIN-SU Need To Be Refrigerated?

Before opening, no. After opening, it depends on the product type.

All CHIN-SU products are safe to store at room temperature when sealed. Once opened, refrigeration is recommended for chili sauce to maintain color, prevent chemical breakdown, and keep the flavor profile stable through the end of the shelf life. Store it in the fridge at 39–46°F (4–8°C). For fish sauce, refrigeration after opening isn't mandatory, but keeping it sealed in a cool, dark spot extends its quality.

How Long Does CHIN-SU Hot Sauce Last After Opening?

Once opened, CHIN-SU hot sauce lasts up to 6 months when stored in the refrigerator. Keep the cap tightly closed between uses. If the sauce changes color, develops an off smell, or separates in a way that shaking doesn't fix, it's time for a new bottle.

What Is the Shelf Life of CHIN-SU Fish Sauce?

Unopened CHIN-SU fish sauce maintains quality for several years. After opening, the sauce stays at peak quality for about 1 year when stored properly: cap sealed tightly, kept in a cool, dry location, away from direct light. Fish sauce is naturally high in salt, which acts as a preservative, but air exposure gradually dulls the aroma and deepens the color over time.
