Import Ammonium Bicarbonate — Buy in wholesale FOB from Supplier in China

Ammonium bicarbonate (NH4HCO3, CAS 1066-33-7) from Weifang Dongpu Industry Co., Ltd. is a food-grade leavening agent supplied as a white crystalline powder with a stated purity of 99.2%. The compound decomposes at temperatures below 60°C, releasing carbon dioxide, ammonia and water, which makes it particularly suitable for low-temperature baking applications where residual ammonia would otherwise taint the finished product. This thermal decomposition profile distinguishes it from other carbonate leavening agents that require higher activation temperatures.

The material is typically manufactured via the reaction of carbon dioxide with ammoniated brine, followed by crystallisation and drying. Standard industrial grades contain minor impurities including traces of chloride, sulphate and heavy metals, with food-grade specifications limiting lead to 2 mg/kg maximum and arsenic to 3 mg/kg maximum under typical Chinese GB standards. The 99.2% purity figure refers to the assay of NH4HCO3 on an anhydrous basis, with the balance comprising moisture (typically 0.3-0.5%) and insoluble residue. The product should be stored in a cool, dry environment away from acids and oxidising agents, as it is hygroscopic and will decompose on exposure to moisture or elevated temperature.

Primary buyers include industrial bakeries, biscuit manufacturers and producers of steamed goods across Asia and the Middle East, who value its rapid gas evolution and clean flavour profile in crackers, flat breads and puff pastries. The material also finds use in the pharmaceutical sector as a buffer and reagent, and in agriculture as a nitrogen fertiliser component. Importers should confirm the supplier's current halal certification status, packaging specifications (typically 25 kg woven polypropylene bags with polyethylene liner), and whether the product is offered under FOB Qingdao or alternative Incoterms. The absence of response data for this Shandong-based supplier means buyers should allow additional time for initial enquiry turnaround.

Weifang Dongpu Industry Co., Ltd. is located on Beigong Street in Weifang, Shandong Province, postal code 261000, in eastern China's established chemical manufacturing corridor. The supplier carries a harbour trust tier with a 0.00% response rate and zero recorded average response hours, which indicates no historical transaction data through the platform and suggests buyers should treat initial contact as unproven. The listing presents itself as a manufacturer rather than a trader, though the profile contains no information about factory scale, year of establishment, employee numbers, or annual turnover.

The source description focuses entirely on product application in food leavening, with no mention of export experience, certification details beyond the implicit food-grade claim, or client references. The supplier does not state MOQ, pricing, lead times, or packaging options. Buyers should verify manufacturing licences, food production licences (SC certification), and whether the company has experience with halal or kosher requirements if relevant to their market. The Weifang location offers proximity to Qingdao port, but logistics arrangements would need to be negotiated directly.
