We are the plant, so the number you get is ours to defend — there is no trading layer between you and the production cost. Here is what actually drives black masterbatch cost per kg, why two quotes for the same-sounding product can differ by a wide margin, and how to get a number you can plan on.
Most price gaps between two quotes are not margin games. They come from a different specification of the same-sounding product.
| Carbon black content | The single biggest driver. Higher loading costs more per kg but lets you run a higher let-down. |
|---|---|
| Carbon black type | Standard pigment black and specialty conductive or UV grades are priced very differently. |
| Carrier resin | PE, PP, EVA and PET carriers carry different raw-material cost. |
| Order volume | Trial lots, pallets and full containers are priced on different scales. |
| Packaging & logistics | Bag size, palletising and shipping terms are usually quoted separately from the resin price. |
| Lead time | Typically 10–15 days after spec confirmation; trial samples in 5–7 days. Stock grades ship faster than made-to-order specials. |
| Port of loading (Incoterms) | FOB Shenzhen, China — one named port, printed on every quotation. Our plant sits about 90 km inland, so inland trucking to the Shenzhen terminal is inside the FOB price; there is no second port to argue about later. CIF is quoted against a named destination port, and EXW or DDP on request where you would rather not handle customs yourself. Both cost more than FOB, and we show the difference as a line item instead of hiding it. |
| Payment terms | 30% deposit, balance against a copy of the bill of lading. That is the structure we open with on a first order, and it is normal for a Chinese plant — the deposit is not posture: carbon black is bought and paid for before we compound. On contract volumes we will discuss open account or a longer tenor once we have three shipments behind us. |
| MOQ | 500 kg per specification for a trial lot. One 25 kg bag of any stock grade can be sampled before you commit; the 500 kg figure applies to a compounded batch, not to a sample. |
| Certifications | ISO 9001 / 14001 / 45001, with certificate numbers and issuing bodies supplied with the quotation so you can check them yourself. For a regulated end use, ask us for the current listing status before you write the grade into a specification. |
Send us your loading, carrier and monthly volume — we will send a firm price and the grade data, not a price range.
Indicative factory ranges so you can sanity-check any quote. Your firm number depends on loading, carrier and volume.
A price is only useful if the entity behind it is checkable. These are the four details a purchasing or compliance desk asks for before the first container, so we put them on the pricing page rather than in an email.
| Legal entity | Guangdong Yijuyuan Plastic Industry Technology Co., Ltd. (广东易聚源塑业科技有限公司), trading as E-LUCK / MasterbatchSource. Registered in China on 27 January 2016. |
|---|---|
| Unified Social Credit Code | 91441322MA4ULT1D8T — searchable on the National Enterprise Credit Information Publicity System (gsxt.gov.cn). It is the number on our invoices, our export filings and our bank account, and it is the same entity that appears on your bill of lading. |
| Plant address | Huangxi Industrial Zone, Shiwan Town, Boluo County, Huizhou, Guangdong 516127, China. 20,000 m², 12 compounding lines, 60,000 t/yr capacity. |
| Port of loading | Shenzhen, China (FOB). Inland haulage from the plant to the terminal is inside the FOB price. |
| Who invoices you | The manufacturing entity above — not a trading company and not a sourcing agent. The same legal person compounds the lot and signs the certificate of analysis. |

Carbon black is petroleum- or coal-derived, and US Customs treats it as a high-priority sector under the Uyghur Forced Labor Prevention Act (UFLPA). If you import into the United States, this is the section your compliance team will read first.
This is a supplier statement based on our own supply chain and on our suppliers' declarations to us. Where your import requires a specific certification, tell us which one and we will confirm in writing whether we hold it before you commit.
You are quoting with the plant, so there is no middle margin sitting between you and the production cost.
The ranges below are for sanity-checking somebody's quote, not for planning. Give us a real specification and volume and we quote a firm price with a stated validity window.
We hold pricing across repeat orders where the raw-material picture allows, and tell you early when it moves.
Test the grade on your own line before committing volume. Your spec stays confidential.
Before you compare two prices per kg, make sure you are comparing the same product:
A 20% grade and a 45% grade are not the same product, however similar the bags look.
Compare cost per kg of finished product, not per kg of masterbatch.
PE, PP and PET carriers are priced and behave differently.
Ask whether packaging, testing and freight are inside the number or on top.
We need four things: carbon loading, carrier resin, monthly volume and destination. With those we send a firm price the same working day. Without them any number would be guesswork.
Usually a lower carbon loading, a different carrier or a different carbon black type. Compare the specification and the let-down ratio before you compare the price per kg.
Carbon black is a commodity and its cost moves. We hold quoted prices for the validity window we state, and we tell you early when the raw-material picture is shifting.
We quote from 1 ton per specification upward. Give us a monthly volume as well as a first-order quantity and we can show the price step between trial and contract volumes.
Guangdong Yijuyuan Plastic Industry Technology Co., Ltd., Unified Social Credit Code 91441322MA4ULT1D8T, registered 27 January 2016, at Huangxi Industrial Zone, Shiwan Town, Boluo County, Huizhou, Guangdong 516127, China. The same entity compounds the lot, signs the certificate of analysis and issues the invoice. You can search that code on gsxt.gov.cn.
Yes, with documents rather than assurances. We issue a signed origin and forced-labour statement with every shipment, naming the carbon black mill and the production batch, and we provide a supply-chain map for the lot under NDA. Our raw materials come from suppliers in Guangdong and neighbouring provinces; on the basis of their written declarations to us, nothing in these grades originates in Xinjiang and no supplying mill appears on the UFLPA Entity List.
Tell us what you are running and how much you need. We reply with a firm factory quote — and, if you want to test before committing, a free 1–5 kg sample compounded on your own carrier resin. No obligation.
Before you compare a price per kilo, look at the line it comes off. This is ours.
