Products classified under HTS 2932.20.50.20
Glucono-δ-lactone Powder
Pure glucono-δ-lactone (GDL) is a heterocyclic lactone derived from gluconic acid, used primarily as a slow-release acidulant in food processing. It falls under HTS 2932.20.50.20 as it is specifically named 'other lactones - glucono-δ-lactone' within the heterocyclic compounds with oxygen hetero-atoms. This white, odorless powder hydrolyzes gradually to gluconic acid, making it ideal for applications requiring controlled pH adjustment.
Food-Grade Glucono Delta Lactone USP
USP-grade glucono-δ-lactone meets pharmaceutical standards for use in food and supplements, classified under HTS 2932.20.50.20 as the pure heterocyclic lactone compound. This high-purity form (GDL) is essential for controlled acidification in yogurt fermentation and surimi production. Its gradual hydrolysis prevents rapid pH drops common with other acidulants.
Industrial Glucono-δ-lactone Bulk Bags
Bulk glucono-δ-lactone packaged in 25kg bags for industrial food manufacturing, specifically classified under HTS 2932.20.50.20 as the named lactone. Used in large-scale tofu production and canned meat processing for texture control and preservation. Meets Chapter 29 requirements for chemically defined organic compounds without added stabilizers beyond transport needs.
Pharma-Grade GDL for Effervescent Tablets
Pharmaceutical-grade glucono-δ-lactone for use in effervescent formulations and controlled-release medications, under HTS 2932.20.50.20. This pure heterocyclic compound provides gradual acidification without taste issues of citric acid. Complies with Chapter 29 as a separate chemically defined organic compound.
Kosher-Certified Glucono Delta Lactone
Kosher-certified glucono-δ-lactone for baking and confectionery applications, classified precisely under HTS 2932.20.50.20. This fermentation-derived lactone replaces chemical leavening agents in matzo production and kosher meat tenderizing. Pure form meets Chapter 29(a) requirements for chemically defined compounds.
GDL 99% Min. Technical Grade
Technical grade glucono-δ-lactone with 99% minimum purity for industrial applications, under HTS 2932.20.50.20. Used in polymer production and metal surface treatment requiring controlled acidity. Qualifies as separate chemically defined compound per Chapter 29 note (a).
Gluconolactone Fermentation-Derived USP
Fermentation-produced glucono-δ-lactone USP grade, classified under HTS 2932.20.50.20 as the specific heterocyclic lactone. Preferred over synthetic routes for 'natural' labeling in clean-label foods. Identical chemical structure qualifies under Chapter 29 organic compound definitions.
