What is the TPC limit for reused cooking oil in India?

FSSAI caps Total Polar Compounds (TPC) at 25%. Oil at or above 25% TPC is classified as unsafe and must be discarded immediately — not blended, filtered, or extended with fresh oil.

How often must restaurants test frying oil TPC?

Under Maharashtra FDA Order 716/2026 §6, establishments doing deep or continuous frying must test TPC with a calibrated meter every 8 cumulative frying hours — not calendar hours.

When is a RUCO daily register mandatory?

If your kitchen uses more than 50 litres of cooking oil per day, you must maintain a daily register of oil purchased, used, TPC readings, and used cooking oil (UCO) handed to an authorized collection agency.

What happens if I pour used oil down the drain?

Illegal under environmental and food-safety rules. Inspectors treat it as a serious hygiene violation; it can trigger improvement notices, licence suspension, and unsafe-food prosecution.

RUCO rules for restaurants: used cooking oil, TPC limits, and fines

Reused frying oil is both a cost lever and a compliance trap. Maharashtra FDA Order FDA/COMM/FOOD/HRE/716-2026/07 (§6) tightened what inspectors expect: calibrated TPC tests, discard at 25%, registers for high-volume fryers, and documented UCO handover. This guide maps the rules — and links to the compliance order hub and edible oil crisis playbook for sourcing and storage.

What is RUCO — and why inspectors care now

RUCO (Repurpose Used Cooking Oil) is FSSAI's program to collect used cooking oil from food businesses and route it to biodiesel — not drains or illegal resale. June 2026 Maharashtra inspections flagged reused frying oil alongside expired stock and missing staff certificates. Oil compliance is no longer a paperwork nicety.

What is TPC — and when must you discard oil?

Total Polar Compounds (TPC) measure how degraded frying oil has become. Fresh refined oil starts near 0%; each fry cycle pushes TPC up. FSSAI's hard limit is 25% TPC — at or above that, the oil is unsafe food and must be removed from the fryer immediately.

Visual fail signals — dark colour, foam, smoke at normal temperature, rancid smell, thick viscosity. Remove on sight; do not wait for a meter reading.
Safe reuse window — most QSRs get 2–3 fry cycles if oil is filtered and topped up; casual dining with lighter fry volume may stretch further. Meter readings beat guesswork.
Never extend past 25% — blending degraded oil with fresh oil does not reset TPC. Discard and log the disposal.

How often must you test TPC? (§6 — 8 frying hours)

Maharashtra Order §6 requires establishments doing deep or continuous frying to test TPC with a calibrated meter every 8 cumulative frying hours — the clock runs while oil is actively frying, not while the kitchen is closed.

Buy a calibrated TPC meter — ₹6,000–12,000 one-time; cheaper than one licence-action day.
Log every reading — date, time, fryer ID, TPC %, action taken (continue / discard).
Reset the 8-hour counter after each test or after a full oil change — pick one method and stay consistent.
Train shift leads — the meter must be usable at 11 pm when the head chef is off shift.

Who needs a daily oil register? (>50L/day)

If your kitchen uses more than 50 litres of cooking oil per day, §6 mandates a daily register covering purchase, usage, TPC readings, and UCO disposal. Cloud kitchens and QSR brands often cross this threshold on a single fryer line.

Register field	What to record	Example
Date	Calendar day of operations	2026-07-06
Oil purchased (L)	Fresh oil received	40 L palm blend
Oil used (L)	Estimated consumption per fryer	52 L total
TPC readings	Meter result + fryer + time	Fryer 1: 18% @ 14:00
UCO disposed (L)	Volume handed to agency	12 L to RUCO vendor
Agency receipt #	Collection challan / invoice	RC-2026-1847

How do you comply with UCO collection?

Used cooking oil must go to an FSSAI-authorized RUCO collection agency — never down the drain, never to informal buyers. Store UCO in closed, labelled drums away from fresh oil. Retain collection receipts for at least one inspection cycle (inspectors ask for the last 3–6 months).

Registration — enroll your outlet with a RUCO aggregator; display the compliance sticker at entrance where applicable.
Collection schedule — weekly for >50L/day outlets; fortnightly may suffice for lighter fry volumes.
Revenue offset — authorized collectors pay roughly ₹20–35/L; a busy fry line can recover ₹5,000–45,000/month.

What are the fines and enforcement risks?

Violation	Typical enforcement	Max penalty (indicative)
TPC ≥25% oil still in use	Improvement notice → suspension	Unsafe food prosecution
No TPC meter / no 8-hour logs	Documentation fail at inspection	Up to ₹1L unhygienic processing
No RUCO receipts / drain disposal	Serious hygiene + environmental flag	Licence action
Missing >50L daily register	Order §6 non-compliance	Improvement notice → suspension

Oil rules sit inside the broader Maharashtra FDA compliance order. For pre-inspection prep, see the FDA raid checklist.

Owner checklist: get compliant this week

Buy and calibrate a TPC meter; assign it to a named shift lead.
Start the 8-hour frying log today — even if readings are manual at first.
If >50L/day: open the daily register (spreadsheet is fine if printed weekly).
Confirm RUCO agency pickup schedule; locate or request past receipts.
Brief kitchen: visual fail signals mean immediate discard — no exceptions.
