Founded in 2000, Linyi Dasheng Import & Export Co., Ltd. has grown from a regional plastics workshop into a manufacturer and exporter trusted by packaging buyers in more than 30 countries. Our factory sits in the Jinluo Technology Industrial Park in Bancheng, Linyi City, one of Shandong's established industrial hubs.
Because we design molds, mold parts and assemble IBC components under one roof, we can explain exactly how each lid, valve and tote is made, and we stand behind it after delivery.
Four integrated capabilities that let us support distributors, tote reconditioners and brand owners with one reliable production partner.
We supply reliable IBC tanks and replacement fittings worldwide. Bulk stock of standard items allows preparation for delivery in about 3 days.
Tailor-made plastic parts from high-quality prototypes to full production runs, matched to your drawings, materials and performance requirements.
Experienced in mold design, flow analysis, machining, maintenance and assembly, with precision up to 0.005 mm for closure-critical parts.
A core specialty for 26 years: IBC lids, bucket and pail covers and industrial caps designed for reliable sealing and repeatable fit.
Select an application to see typical industries and the product lines buyers usually source together.

IBC tanks safely store and transport large volumes of liquids and powders such as chemicals, food ingredients, pharmaceuticals and agricultural inputs. They are also widely reused for rainwater harvesting, waste management, oil and gas operations and aquaponics systems.

Plastic lids seal, protect and preserve products from food items such as dips, snacks, wet wipes and dairy to industrial goods like paints, chemicals and bulk buckets. Designs range from snap-on and press-fit lids to tamper-evident, airtight and heat-sealable closures that keep contents hygienic and secure in transit.

Plastic drums store and transport materials that must not leak, including many hazardous substances. Paired with sorbents, they add a further layer of spill protection, and they are equally suited to shipping food, beverages and oils.
As an IBC bulk container solutions provider, we manage the full product lifecycle with clear pre-sales, in-production and after-sales responsibilities that protect your interests.

We confirm the stored media, filling method, transport route and target market so the tote, gasket and lid type are specified correctly from day one.
Tailored IBC and lid design, plate making and material customization to meet the specific needs of each customer.
Flow analysis, precision machining up to 0.005 mm and in-house mold maintenance keep dimensions stable across long production runs.
One-stop manufacturing and branding services, from prototype development to mass production, supporting custom logos and technical specifications.
Finished parts are checked before packing, and shipments are prepared with the documentation your freight forwarder and customs broker need.
Stock items can be prepared in about 3 days, and our team stays available after delivery for replacement parts, reorders and technical questions.
Price alone rarely predicts tote performance. These are the checkpoints our engineers recommend to procurement teams comparing IBC tanks and fittings.
Ask for virgin HDPE and consistent wall thickness. Under-weight bottles are a common cause of bulging, cracking and bursting under load.
Check steel tube gauge, weld quality and galvanizing, and match the pallet base (steel, plastic or aluminum) to your forklift and racking setup.
Match the gasket material, such as EPDM, NBR or FKM, to the chemical you store, and confirm valve thread standards fit your existing hoses.
Use breathable lids for gassing media or fast filling and draining; use gasketed sealing lids for long-distance transport and storage.
Nameplates with batch and date data simplify fleet management. For dangerous goods, request UN-marked models and supporting test documentation.
