Minor Variation in Chemical Composition Matters in Eyes of Law: CESTAT Denies Concessional Duty on Boronated Calcium Nitrate [Read Order]

The Ahmedabad Bench of the Customs, Excise and Service Tax Appellate Tribunal (CESTAT) determined that "Boronated Calcium Nitrate" is a distinct product from "Calcium Nitrate”, disqualifying from concessional customsduty benefits.

Yara Fertilizers, the appellants, imported a product branded as "YARALIVA Nitrabor Calcium Nitrate with Boron." The company classified the fertilizer under the standard tariff heading and claimed a reduced duty rate of 5% provided for "Calcium Nitrate" under a 2017 notification.

However, the Revenue Department challenged this, arguing that the addition of boron created a separate commodity not covered by the specific language of the exemption. This difference led to a demand for over ₹57 lakh in differential duties.

In its defense, the appellant argued that the addition of boron was minuscule roughly 0.3% and did not change the product's "essential character."

They also asserted that since the product was still classified as calcium nitrate for general customs purposes, it should logically qualify for the corresponding tax break. They appealed to the principle of "commercial parlance," suggesting that in the trade world, the two are seen as essentially the same.

The Revenue added that on Fertilizer (Control) Order, 1985, "Calcium Nitrate" and "Boronated Calcium Nitrate" are categorized differently. The former is listed as a 100% water-soluble fertilizer, while the boronated version is classified as a "fortified fertilizer" with a slightly lower solubility of 99.5%.

The Tribunal noted that even minor variations in chemical composition and nutrient solubility matter in the eyes of the law. By looking at the Fertilizer Control Order, the Tribunal found that the two products are governed by different quality standards and definitions.

The bench of Dr. Ajaya Krishna Vishvesha (Judicial member) and Satendra Vikram Singh (technical member) said that when a tax exemption is at stake, the burden of proof lies entirely on the taxpayer to show they fit exactly within the Four Corners of the notification. If there is any ambiguity or "grey area," the interpretation must favor the government.

Since the notification was specifically named "Calcium Nitrate" and made no mention of its boronated or fortified variants, the benefit could not be extended by implication.

Therefore, the Tribunal dismissed appeals and denied the exemption.
