Product Overview
EDTA, also known as Edetic Acid, is a classic aminopolycarboxylic acid chelator.
CAS No.: 60-00-4
EINECS No.: 200-449-4
EDTA molecule contains multiple carboxyl and amino groups, presenting strong coordination capacity toward calcium, magnesium, iron, copper, zinc and other heavy metal ions. It forms stable water-soluble chelate complexes to suppress metal ion catalysis, sediment formation and oxidation deterioration.
Compared with EDTA salts, EDTA free acid features lower water solubility and is suitable for formulations requiring acidic environment or further neutralization to produce EDTA disodium / tetrasodium salt.

Frequently Asked Questions(FAQ)
1. Q: What would you do to guarantee the product quality?
To fully guarantee stable and reliable product quality, we implement full-process control covering Quality, Health, Safety and Environment (QHSE) with systematic measures,conduct multi-stage product testing with full batch traceability, adopt strict health & environmental control to avoid product contamination, carry out regular QHSE audits and continuous system optimization, plus standardized storage and logistics management. Every link follows unified QHSE rules to eliminate quality risks fundamentally.
2. Q:Can you provide COA / MSDS /TDS before order?
Yes, we can provide complete COA, MSDS /TDS documents for your reference prior to placing orders. Please advise the exact product grade and quantity you intend to purchase, and we will send you the latest updated versions of these technical documents promptly by email. All files are issued in accordance with international QHSE standards,for your customs clearance, laboratory testing and internal risk assessment.
3. Q: What about your price?
We offer flexible and favorable prices for bulk orders. To provide an accurate best quotation,
kindly advise: (1)Required product grade (2)Order quantity (3)Preferred trade term (FOB / CIF) (4)Destination port
Meanwhile, we can supply complete TDS, SDS and COA for your reference before order confirmation. We believe this is an effective way to build long – term business with our customers and earn good reputation.
4. Q: What payment terms do you accept?
We support multiple flexible payment terms to meet different cooperation demands:
(1)T/T (Telegraphic Transfer): 30% deposit in advance, 70% balance against copy of Bill of Lading; full T/T in advance for small trial orders.
(2)Irrevocable Letter of Credit at sight (L/C at sight): Acceptable for large bulk orders, issued by reputable international banks.
(3)Negotiable payment terms can be discussed for long-term cooperative clients with stable monthly orders.
5. Q:What about the order lead time?
Our standard production lead time is 10–15 working days .
(1)For T/T payment: 30% deposit by T/T in advance, balance against scanned BL copy. After your deposit arrives, we will schedule raw material procurement and production immediately within the 10–15 day cycle. This mode safeguards mutual capital safety: the deposit locks exclusive production capacity for you, while you only settle the rest after seeing loading evidence.
(2)For L/C payment: We accept irrevocable sight L/C issued by first-class international banks. The 10–15 working days lead time will start running after we receive and verify the operative L/C text without unachievable clauses. A formal L/C serves as bank credit guarantee for both parties, eliminating default risks effectively. We will review L/C terms thoroughly before production to avoid discrepancies and potential financial losses for both sides.
6. Q:Which ports can you ship from?
We support shipment from Qingdao Port and Tianjin Port of China; you can choose the loading port as per your actual demand.
7. Q:Can you arrange thirty party inspection during loading?
Yes, we fully support third-party inspection during container loading. You can appoint your designated inspection agency to attend the whole loading process at our warehouse. Our QHSE team will coordinate all preparation work in advance, including raw batch COA checking, product appearance verification, weight tally, packing integrity supervision and sealing recording.
8. Q:Do you accept OEM packaging (private label)?
Yes, we support OEM & private label packaging service for our products. You can provide your customized brand logo, label design, bag/barrel printing artwork and customized packaging specifications. Our production team will arrange tailored packaging according to your design files. For OEM orders, there is a minimum order quantity requirement.
