HS Code for Dextrin adhesive

HS code 3505.20 is reserved for glues based on starches, dextrins, or other modified starches. The classification is determined by the product's formulation as a prepared adhesive. Dextrins are a group of low-molecular-weight carbohydrates produced by the hydrolysis of starch or glycogen. When these substances are prepared as glues—often by adding water, preservatives, or other additives—they fall under this specific subheading. This classification is distinct from the raw modified starches themselves, which are found in 3505.10. The use of dextrin-based adhesives is widespread in the paper and packaging industries due to their high tack, water solubility, and biodegradable nature. Under the Harmonized System, Chapter 35 covers albuminoidal substances, modified starches, and glues. For a product to be classified under 3505.20, the starch or dextrin component must be the essential constituent that provides the adhesive property.

Products Included

• Dextrin-based liquid glues
• Starch-based adhesives for corrugated board
• Modified starch glues for labeling
• Envelope and postage stamp adhesives
• Vegetable-based glues for paper bags

Common Misclassification

The most frequent misclassification is with HS code 3505.10, which covers dextrins and other modified starches that are not yet prepared as glues. Another common error is using 3506.10, which is for products suitable for use as glues or adhesives put up for retail sale in packages not exceeding 1 kg. If the dextrin glue is in a large industrial drum, 3505.20 is correct; if it is in a small 500g bottle for consumers, 3506.10 may take precedence.

FAQ

What is the HS code for dextrin adhesive?

The HS code for adhesives and glues based on dextrins or starches is 3505.20.

How does 3505.20 differ from 3506.91?

HS code 3505.20 is specifically for starch/dextrin-based glues, while 3506.91 is for adhesives based on polymers or rubber, which are chemically distinct.
