GST Rate related issues.

Based on the latest GST reforms that took effect on September 22, 2025, the GST rate for the products you've listed remains 18%.

• Vinegar (HSN 220900): Vinegar and its substitutes, including brewed and synthetic vinegar, are classified under this HSN code. The GST rate for these products continues to be 18%.

• Phenyl (HSN 3806): While "phenyl" as a product isn't listed with a specific HSN, the HSN code 3806 covers "Rosin and resin acids, and derivatives thereof; rosin spirit and rosin oils; run gums." Phenyl-based compounds and similar miscellaneous chemical products in Chapter 38 generally fall under the standard 18% GST rate.

• Bleaching Powder (HSN 28281010): Bleaching powder, specifically "commercial calcium hypochlorite," is classified under this HSN code. The GST rate for this product is 18%.

The rates are HSN-specific, so don’t apply one rate across all three products. Also, the dates and HSNs in your question need checking against the product descripttions:

• Vinegar (HSN 2209): This heading generally attracts 12% GST; confirm the exact product and current rate entry before invoicing.
• “Phenyl” (HSN 3806): HSN 3806 covers rosin and resin acids, not ordinary phenyl disinfectant. Phenyl’s classification and rate depend on its formulation and use; check the product label/specification and applicable HSN entry.
• Bleaching powder: HSN 2828 10 10 is associated with bleaching powder, but verify the current GST rate against that exact tariff item and product descripttion. The HSN code alone should not be treated as proof of the rate.

For invoices dated 22 September 2025, check the rate notification effective on that date and the GST portal’s current rate finder; I can’t verify from the information provided whether a rate change applied then. The phenyl formulation and the relevant rate notification are needed to confirm the latter two rates.

Correct product classification and rate mapping are essential to avoid invoice amendments and return mismatches. Manual HSN-by-HSN research is difficult, and automation can reduce repetitive checks while keeping classification and rate decisions under professional judgment.

Vinegar, phenyl and bleaching powder – rates after 22.09.2025 and one HSN correction:
• Vinegar (heading 2209): continues at 18%, listed in Schedule II of Notification 9/2025-CT(R). The 12% mentioned in the latest reply is not correct; the 12% slab was largely removed in GST 2.0.
• Bleaching powder (2828 10 10, commercial calcium hypochlorite): no change, 18%.
• Phenyl: HSN 3806 is wrong, as rightly noted; 3806 covers rosin and resin acids. Phenyl sold as a disinfectant is normally classified under 3808 94 (disinfectants), which remains at 18%. Correct the HSN in your item master and in GSTR-1 Table 12.
• So your existing 18% billing on all three items is correct both before and after 22 Sept 2025; only the phenyl HSN needs fixing.
• For any future doubt, check the item in Notification 9/2025-CT(R) on cbic-gst.gov.in, or use the GST rate finder on gst.gov.in, rather than private charts.
