Leather Tanning & Deliming Fixation
Provides gentle, uniform pH reduction in tanning drums, enhancing chrome penetration and cross-linking without damaging collagen fibers or causing grain harshness.
Packaging drawings are schematic. The actual pack, liner and closure are confirmed on the proforma and may vary by source lot.
HCOOH · MW 46.03 g/mol · Colorless
Supplied as colorless, transparent liquid with pungent, penetrating odor at a guaranteed assay of ≥ 85.0% HCOOH. Available in one controlled grade and 3 standard pack configurations, with lot-specific analytical release from the Ankleshwar terminal.

Documentation, pack choice, storage and custom specifications for this line.
Ask the technical deskEvery dispatch carries a lot-specific certificate of analysis, the current safety data sheet revision, a GST tax invoice, a packing list and the origin weighbridge slip. Export consignments add an IMDG declaration and, on request, a certificate of origin. The COA is issued against the actual batch number and retained in our archive for twelve months.
Stock options for this line include 35 kg HM-HDPE Carboys; 250 kg HDPE Drums; 1,200 kg IBC Totes. Trial work usually starts with a carboy or drum; production volumes move to IBCs, jumbo bags or tankers where the product and site permit. The load estimator below converts tonnage into units, pallets and container utilisation for each pack.
Store in acid-resistant, ventilated chemical sheds away from heat sources and strong oxidizers. Vapors are pungent and corrosive to respiratory membranes. Recommended shelf life: 24 months in sealed HDPE containers. Incompatible materials include Sulfuric acid (decomposes into toxic carbon monoxide gas); Strong bases; Oxidizing agents.
Yes, for repeat volumes. Send the assay, moisture, trace-metal and packing limits to the technical desk. We check them against the source plant’s capability, run a trial lot where needed, and hold the agreed limits in the annual supply agreement. Standard stock material remains available in parallel.
Three short steps — product, volume, company — route your requirement to the Ankleshwar desk with the grade and packing already attached. Quotes are issued against a real lot, not a price list.
