FAQ
Frequently asked questions
Practical answers about MOQ, samples, packaging, shelf life, lead time, HS code and payment terms.
What is the minimum order quantity (MOQ)?
For liquids, generally one 20'FCL (about 20–24 t depending on packaging); for powders, 5 t. New customers can start with a 1 t trial order. We keep safety stock for grades under regular contract.
Can we test samples first?
Yes. We suggest sending 2–5 kg of your local cement, SCM and aggregate samples. We run compatibility tests and return the recommended dosage together with a trial mix report. Samples are free; freight is collect.
What packaging options are available?
Liquids: 1000 kg IBC totes, 200 L plastic drums, or 22–24 t flexitanks. Powders: 25 kg composite paper-plastic bags or 500–1000 kg jumbo bags. OEM labels and custom packaging are supported.
Shelf life and storage conditions?
Liquid PCE mother liquor: 12 months in sealed original containers at 5–35 °C away from sunlight. Powders: 24 months in dry conditions. Protect from freezing and prolonged sun exposure; winter shipments can be insulated on request.
What is the lead time?
Standard grades in stock: 7–10 days. First order of a custom formulation: 15–25 days including trial mix confirmation. Booking and sea transit depend on the destination port.
HS code and export documents?
Concrete admixtures are normally classified under HS 3824.40. We provide COA, MSDS, TDS, packing list, commercial invoice, certificate of origin, plus non-hazardous classification or third-party test reports as required by your country.
Can you adjust the formulation to our local cement?
This is what we do most. Once we receive your cement sample, compatibility results and a recommended dosage are typically ready within 5 working days, and production is scheduled after your confirmation.
What payment terms do you accept?
Commonly T/T (30% deposit, 70% against B/L copy) or sight L/C. Credit terms can be discussed for long-term customers.
