Bronopol Price & Supplier Guide for India and Export Buyers

Sourcing Bronopol at a fair price starts with understanding what genuinely drives cost, what a reasonable minimum order quantity looks like, and how to separate a genuine manufacturer from a repackaging trader. This guide covers all three for buyers in India and export markets.

What Determines Bronopol Price?

Bronopol price is driven by verified purity/assay, product grade (technical, cosmetic, or pharmacopoeia grade), whether the seller is a manufacturer or trader, pack size, freight and Incoterms, and documentation such as COA and SDS. Compare quotes only on a like-for-like specification.

Purity and assay: confirm the quoted price is for the stated assay (commonly 99% minimum for technical grade). Ask for the Certificate of Analysis specification range on every quote. Grade: technical/industrial grade, cosmetic grade, and pharmacopoeia grades (IP, BP, Ph. Eur., USP) carry different cost structures reflecting different testing and documentation requirements. Packaging and order size: 25 kg fibre drums or HDPE bags carry a different per-kg cost than larger bulk packaging; ask about available formats for your order size. Freight and Incoterms: FOB, CIF, and CFR quotes differ by destination port and by Bronopol's hazard classification for transport (UN 3241, packing group III). Documentation: COA, SDS, REACH support, and pharmacopoeia compliance documentation add administrative cost that should be reflected transparently in the quote.

What Packaging and MOQ Are Standard for Bronopol?

Bronopol is commonly supplied in 25 kg fibre drums or 25 kg HDPE bags with liner, with this pack size often serving as the practical MOQ for new buyers. Larger bulk packaging can typically be arranged for regular repeat buyers with higher volume requirements.

25 kg fibre drums and 25 kg HDPE bags with liner are the standard commercial pack sizes across most suppliers reviewed, suiting cosmetic, pharmaceutical, and industrial buyers at small-to-medium order volumes. For buyers with larger, regular requirements, bulk packaging arrangements can typically be negotiated directly with the manufacturer. Most suppliers can also arrange small samples (500 g to 5 kg) for formulation trials before a first commercial order.

How Do I Evaluate a Bronopol Supplier?

Confirm whether the seller is the actual manufacturer or a trader, request a current COA and SDS before ordering, verify ISO 9001:2015 certification, check pharmacopoeia compliance documentation if needed, and test a sample before committing to a bulk order.

Manufacturers typically provide more consistent batch-to-batch quality and better bulk pricing than traders, who may source from multiple factories with specification drift between batches. Request a current Certificate of Analysis and Safety Data Sheet before ordering, and compare the assay, appearance, melting point, and moisture content against your specification or a recognised pharmacopoeia reference if applicable. For pharmaceutical or cosmetic-grade buyers, confirm the supplier can provide pharmacopoeia-specific documentation (IP/BP/Ph. Eur./USP compliance) if your application requires it — not every industrial supplier carries this capability. Request a sample and run your own preservative efficacy or identity testing before committing to a bulk order, particularly with a new or unfamiliar supplier.

Frequently asked questions

Why do Bronopol prices vary so much between suppliers?+
Differences reflect verified purity/assay, grade (technical vs cosmetic vs pharmacopoeia), whether the seller is a manufacturer or trader, packaging size, and documentation included. Compare quotes on a like-for-like specification.
What is a reasonable minimum order quantity for Bronopol?+
Most suppliers set a practical MOQ around one standard 25 kg drum or bag, with smaller sample quantities (500 g-5 kg) available for formulation trials.
Do I need pharmacopoeia-grade Bronopol for pharmaceutical use?+
Yes. Pharmaceutical formulations should use Bronopol meeting the specific pharmacopoeia monograph applicable to your product (IP, BP, Ph. Eur., or USP), which carries tighter purity and testing requirements than standard technical grade.
How can I verify a Bronopol quote is for genuine 99% assay material?+
Request a current Certificate of Analysis showing the assay specification range, and consider an independent third-party assay on a sample before placing a large order with an unfamiliar supplier.
