Compliance steps

1
File the bill of entry under HSN 3506 99 10, confirming that the product is a synthetic adhesive whose primary reactive component is phenol, urea, or cresol combined with formaldehyde. Misclassification into adjacent tariff lines attracts re-assessment and potential short-levy recovery under the Customs Act, 1962.

2
Verify that the product is not a cockroach trap or mosquito repellent before filing under this CTI; such products merit classification under Tariff Item 38089199 per CBIC Circular 28/2013. A misfiled entry is liable to reassessment and applicable differential duty.

A word of counsel

The single most common error on this tariff line is mis-describing a formaldehyde-resin adhesive as a general-purpose prepared adhesive under 3506 99 90, or conversely, classifying an insecticidal adhesive trap under this CTI rather than 3808 91 99. The 8-digit distinction turns on the primary functional component, not trade name; customs officers routinely request a technical data sheet or supplier composition certificate to confirm phenol-urea-cresol-formaldehyde as the main reactive constituent.

Frequently asked

Does HSN 3506 99 10 require BIS certification?

No, no BIS Quality Control Order covers synthetic phenol-urea-cresol-formaldehyde adhesives. Import of this product is governed by standard CBIC customs procedures under the Customs Act, 1962, with a Free ITC (HS) import policy and no sectoral PGA licence required.

How does CBIC Circular 28/2013 affect classification of adhesive-based pest-control products?

Cockroach traps and mosquito repellents — even those presented in adhesive form — merit classification under Tariff Item 38089199, not under 3506 99 10; the circular instructs officers to reclassify any such product filed under Chapter 35.

Is any PGA NOC or pre-import registration required for this adhesive?

No PGA-specific NOC, registration, or permit is mandated for HSN 3506 99 10 under the current regulatory framework; standard CBIC bill-of-entry clearance is sufficient provided the product description and composition are accurately declared.
