Why a chemical buyer keeps a second supplier, and how to become the first call

Why plants that buy chemicals often keep a backup source, and what a supplier does, lot by lot and call by call, to become the one they ring first.

Chemical makers often hear that the plant is happy with the material but also buys from another supplier. A plant keeps a second supplier because one late tanker or off-spec lot can stop a line, and the purchase manager takes the blame. You are unlikely to talk them out of it. The aim is to be the one they ring first: the larger share, the forecast, the first word on a new requirement. That is earned through lots that match, contact with the plant chemist and stores, and warnings that arrive before the problem does.

Why the backup exists, from the buyer's side

A lot arrives that passes your certificate of analysis but behaves differently in their process. A dye house sees a shade shift; a paint maker sees a viscosity change. Their lab now has to work out whose fault it is while production waits. A feedstock tightens and makers may ration supply to their largest accounts. The monsoon closes a ghat road and the tanker sits for three days.

Then there is approval. Getting a new source past the plant's quality team takes trials, samples and paperwork. No buyer wants to start that during a crisis, so they keep a second source approved and alive with small orders.

Where do you stand on the buyer's list?

Many suppliers do not know. They know they get orders, not what those orders mean. Read your position from the buyer's behaviour, then work on the one step above it.

Your positionWhat the buyer doesWhat moves you up a step
Approved, seldom orderedKeeps your documents on file and buys a trial drum once in a whileA reason to order: a shortage you can cover, or a product the main supplier does not make
BackupCalls you when the main source is short or lateDeliver every shortage order completely and on the day promised, then ask for a fixed share
Split supplierOrders regularly, divides the volume with another sourceLots that stay clear of lab queries, and contact with the chemist, not only purchase
First callGives you the larger share and tells you about changes earlyHold it by warning them first and by bringing the next product
Sole supplierBuys only from youUncommon, and not always good for you (see the last section)

The jump that matters most is from backup to split. A backup who performs in a shortage has earned a hearing. Ask for it then, while the stores in-charge still remembers who covered the gap. Our post on getting on a company's approved vendor list without the file stalling covers getting onto the list in the first place.

What the first call gets you, and what it costs

A first-call supplier hears about volume changes before the order arrives. They are asked to trial the new grade the plant needs for a new customer. They get the price conversation before a tender goes out, not after.

It also costs something. The plant will expect you to hold stock for them, take the Saturday evening order, and carry credit through their slow quarter. Storing chemicals near a customer, or on their behalf, has its own rules on storage and transport. Those differ by chemical and by state and they change, so check with your own adviser or the regulator before you offer it.

Decide whether you want that before you chase it.

Who to stay in touch with, and what each conversation carries

Steady contact is not a call to ask "any requirement?". Each contact should carry something new.

  • The plant chemist or process head. Send the certificate of analysis before the tanker leaves, not with it. Ask what their incoming test showed on the last lot, and keep a retained sample of every lot you send.
  • Stores. They know the consumption and the reorder level. A supplier who asks "how many days of stock do you have?" before a long holiday gets the order.
  • Purchase. Give notice of a rate change with the reason, the date it takes effect, and how long the current rate holds.
  • Accounts. Clean invoices that match the purchase order. A disputed invoice sours the relationship faster than a late truck.

One rule matters more than the rest: tell them about a problem before their lab finds it. If a lot tested at the edge of the range, say so and offer to replace it. The supplier who called first is the one remembered. This is the core of strategic account management for a chemical maker.

Imagine an auxiliaries maker in Kolhapur

Imagine, as an invented example, a maker of textile auxiliaries in Gokul Shirgaon MIDC, supplying softeners and wetting agents to process houses in Ichalkaranji. For one process house, it is the backup on a silicone softener. A larger Gujarat supplier holds the main share.

For a year the owner tried to move up by quoting lower on every call. The process house forwarded the rate to the Gujarat supplier, who matched it. The share did not change, and the margin on that product fell by about ₹4 a kilo.

Then the main supplier ran short during a raw material squeeze. The Kolhapur maker covered three weeks of supply, in full, from a plant two hours away, at some cost in overtime and a late payment from another buyer. This time, instead of quoting a rate, the owner went to the dyeing master. The question was which property of the softener caused trouble on their machines. The certificate for that property then went ahead of each lot. The maker kept retained samples and offered to replace any lot the lab queried. Then purchase was asked for a fixed share on that one product, at the existing rate.

Purchase gave about a third of the volume, not the half asked for. Over the next seasons the dyeing master began calling first when a new fabric order needed a softener trial. That trial became a second product.

When staying the second supplier is the right call

Push for first call only when you could carry the whole volume if the other source failed. Being relied on and then missing a delivery is worse than never being relied on.

Stay where you are if one buyer would become a large part of your plant's output. A single account that large sets your prices and your payment terms. Stay where you are, too, for commodity products bought on the day's rate by the tanker. Those buyers move with price. Keep your approval current and compete load by load.

Plan the next shortage at one backup account

Pick the customer whose orders arrive only when someone else is short. Find out who their chemist and stores in-charge are, and what went wrong with the last lot from the main supplier. Then decide now how you would cover the next gap. The chemicals hub has the rest of the trade. If you want help building that account plan, or the customer retention routine around your top buyers, tell us what you need.

Questions

Questions owners ask.

Should I cut my rate to become the primary supplier?
Not usually. A lower rate from the backup is an easy lever for a purchase manager to use against the main supplier, who may match it. You end up with the same share at a thinner margin. Spend the effort on lot consistency and early warnings, and keep any price move for a larger, committed share.
How do I find out what share of the buyer's business I have?
Ask the stores in-charge what the plant consumes of that product in a normal stretch, then compare it with your own dispatches. Some will tell you roughly. If they will not, your order pattern tells you: regular orders mean a split, orders only during shortages mean you are the backup.
Is it worth getting approved if I will only be the backup?
Yes, if the approval did not cost you a long trial at your own expense. Approval is the hard part for the buyer, and a supplier already on the list is the first one called when the main source fails. Being called in a shortage is where many first-call positions begin.
